Simple? You mean cherry picked parts of studies that support his views. People do your own research, don't be a Jason Fung sheep please! If you demonize Insulin, you either know extremely little about how the body works or you are trying to sell thing to people looking to blame anything but themselves for being overweight. Jason Fung is the latter.
Paul Jansen What?? Who's selling something? Who demonized insulin? Did you read my comment? I expressed MY opinion on Dr. Fungs presentation. How you took sales and demonizing out of that is beyond me! What I "cherry picked" out of your comment is that you've COMPLICATED a simple observation.
No no I'm not talking about you at all, I'm talking about the good doctor. He cherry pics to get people on board with his ideals and makes a ton of cash from his books/videos. Sorry about that lol Feel free to read, it's genuinely objective. www.myoleanfitness.com/evidence-caloric-restriction/
Being a doctor myself I followed your diet and changed my eating habits low carb high fat and protein not only did I lose weight got healthier even could control diabetes. Brilliant reasoning, Intelligent thinking Dr Jason.
@Rusty you don't know what you are talking about! Sugar, refined foods, starches cause diabetes! It also causes candida yeast to over grow and become fungus in your body that causes cancer. Many are now practically being born with cancer. And cancer is becoming rampage. Diabetes is high sugar in the blood. High sugar or starch kills the good friendly bacteria in your gut! The diet is to substitute sugar to high fat for a few weeks for the transition. The body then starts to use your body fat thus losing drastic weight. You maintain eating your raw veggies salads, good fats and low meats. This is the best diet. Plus adding intermediate diet really adds to the punch of loosing weight. There some people that is keep their weight down and are extremely healthy is ONE healthy good meal a day. Great for diabetics because the constant snacking or eating forces your body to produce insulin and is not good. I met people that eat this way and are super healthy, alert, full of life.
Reduced my sugar intake to less than 10 grams/day. Combined it with resistance training (3 times per week) and I eat a bit less carbs and fat, but more protein intake to gain muscle mass. Lost my belly and I look damn fit. This happened in 3 months time.
@@itscooltobeyou No, I bought a dumbbell set and train at home. Did some research and watched some professionals on youtube like Jeff Cavalier (athleanX) and Mike Thurston. My basic routine is: Dumbbell floor press (chest), windshield floor wiper (abs), dumbbell skull crusher (triceps), Squats (legs), dumbbell Curl (biceps), bend over rowing (back). I do 5 sets of 10 reps for each exercise. Most of the exercises I do are what they call 'compound' exercises so you train different body parts at once. I switch some exercises after a while to shake up things a bit like eg I will do Hammer curl instead of normal curl and eg dead lifts instead of squats.
I need to add another comment. The food industry DOES NOT MAKE MONEY OFF OF FASTING!!! nor , does the pharmaceutical industry. When, "they tell me to go left, I am going right". Thank you Doctor Fung for a way of living that is healing.
Or the diet industry. God forbid people found out they don't need sugary meal replacement shakes to lose weight, or that that sports drink and energy bar in the gym does you zero good.
Big Food and Big Pharma have to keep people obese and sick to make big profits and the NHS with corrupt Senior civil servants, Corrupt, corrupt MPs are shills and colluding with big food and big pharma. The wrong food to eat they are pushing will make and keep people obese and make them sick. The British NHS terrible nutrition advice is proof of this. htps://www.nhs.uk/live-well/eat-well/ "base meals on starchy foods like potatoes, bread, rice or pasta" "Aim to eat at least 2 portions of fish a week, including 1 portion of oily fish." "have some dairy or dairy alternatives (such as soya drinks)." "Having a sliced banana with your "morning cereal" is an easy way to get 1 portion". " Eating a lot of saturated fat can raise cholesterol levels in the blood, and having high cholesterolraises your risk of heart disease". A few excerpts from the NHS website...GASP! For the truth on optimum human health read the book called the Obesity Code by Dr Jason Fung. UA-cam Cole Robinson Snake Juice too for a man who walks the walk. Share this with your family and friends...it may literally save their life.
Rebecca, absolutely right. That’s the same philosophy I use with the leftists. When they say good is evil and evil is good, you know the opposite is true. 💯
I feel like crying each time I see this man. It hurts to have spent lots of time n money doing the wrong things n same time really heart touching to know the little right thing to do. I can't believe my weight loss in three months. I'm soooo grateful. I've made others around me listen to him too.
I take breakfast at 2pm earliest, I exercise almost every (free home workouts from fitness youtubers), I avoid sugar as best as I can. Sometimes I fast for 24 hours or more. I've been living this way for over a year now and I'm keeping the weight off. Fasting is anyway the game changer, cus I also did workouts before now.
@@christophercruz117 you are welcome. It's quite hard. I equally have two 5 years old and work full time. In the beginning it's hard, but gradually u get used to it. Also watch other doctor Fung videos on fasting hacks like coffee, green tea and salt water. They help alot.
@john smith Sometimes I will have a sore throat or just be under the weather and I'm teaching and I think Oh no, I am not gonna be able to teach very well today, but I actually do better because i say less
My doctor recommended this system [Go here=== *2WeightLossFast. Com* ]to me. I was looking to lose a significant amount of weight, and needed a plan. This diet book has done miracles for me and my husband! We follow the plan and both lost over 20 pounds in the first month. This is a well written book that will give you the tools you need to start eating healthier and regain control of your metabolism. I can't say enough good things about this book and the diet. This was a life changer for us!?
maybe the 1500 cal was what worked, but keto heals your metabolism, prevents craving, makes you healthier & more energy. Started for weight loss, stayed for the health benefits. keto is amazing.
@@fitnessnutritionandsoul3618 no, it's keto, 1500 total calories with 60% coming from carbs, the current SAD, increases insulin. This closes the fat burning process, no workout or food fixes these issue. Keto does. Did for me, went from 269 to 185 in a year and 4 months. You are just stating otherwise, because you've been brainwashed. And don't like it when others go against your views and ideology.
They do teach this at medical school,but there they teach the proper version. What he's neatly skipping over is that if you have insulin resistance as a result of too high blood sugar levels for too llong(type 2 diabetes) and you reduce the amount of energy you eat, then the body will pull on some of the energy it has available to cover the difference, and some of this energy will be taken from the excess energy in the blood - the blood sugar. If you eat less than you need and lose weight, blood sugar levels will go down. When/if the blood sugar levels go down and stay down,eventually insulin sensitivity returns to more normal levels. This is why weight loss is an integral part of treating type 2 diabetes. Yes,the body will adapt to the energy deficit by trying to reduce how much it spends, but you have some leeway. The bigger the gap between what it wants and what it has, the faster this adaptation will occur. If the deficit is smaller, the body can keep losing weight for longer before it gets upset,and you have more space to make more changes. So he's basically giving you half the truth in order to push his view,which is troublesome.
this is highschool biology where I live.. not with these metaphors ofc if you mean US school then yeah, they should teach a LOT more things there from what I've heard
I am 74 YO and began the 18/6 fast at the beginning of this year and find it so easy to perform. No counting calories or special, expensive foods. Have lost about 1/2 pound per day. Tried going on a 48 hour fast and was successful, so may add it periodically. I try to get in a 3 to 5 mile walk in every day, as well. The key is PATIENCE. If I can maintain this fat burning rate, I am looking forward to warmer weather and biking season and will see how that goes.
@@martynblackburn1977 he saves lives, like mine and many others, oriented specifically on diabetes, one year and im sane af since i went to emergency for diabetes.
I did 16/8 intermittent fasting and finally I'm no longer insulin resistant :D. My insulin levels were constantly high for years, and took me 5-6 months of IF to finally control that goddamn hormone! I can't describe how happy I am ;_;
@@nottoday4820 I ate lots of white meat and healthy fats (from nuts and seeds), along with whole wheat bread and low glicemic fruits such as berries. Twice a week a had a small portion of brown rice or pasta as a side dish. This is what worked for me tho and I'm still doing it, a professional should give you a complete guide according to your needs 😉
So, it's not a permanent condition? Damn, I just learned that I'm insulin resistant 15 min ago and I had a epiphany about how I hurt and damaged my body for so long. I'm pretty fit but not as healthy as I should. Been doing IF but I'll start incorporate low carb too. Any tips to make the process smoother?
@@beatriceladouce965 excersice is your best ally!! I do cardio and resistance training 5days a week. If you crave sweet treats like I do, try to replace sugar with tagatose for baking/cooking. Tagatose is safe and has minimal effect on your insulin levels. I don't know what else I can say, but good luck!! You can avoid type 2 diabetes by changing what you eat ☺️
I figure it’s going to take me at least that long. I know it’s going to turn around. My problem is I do 20:4 fasting and I am not hungry at ALL. When I do eat my one meal in the afternoon ( around 3pm) I’m stuffed and when I put it in my calculator app...I rarely go over 1,000 calories.
This video was the one that opened my eyes, changed my life, over a year ago. After watching this, and subsequently "Fasting as a Therapeutic Option for Weight Loss" I looked my wife in the eye and said "I finally understand. I'm going to lose weight and keep it off, I will never be overweight again" That was over a year ago and I am finally, for the first time since I was a young child, I feel healthy. I'd managed to lose weight before but never felt healthy and never kept it off until now.
*Intermittent Fasting + Low Carb (and very low to no sugar) is KEY to weight loss!* I lost 100lbs only eating red meat, salmon, eggs, berries, Kefir and cooking in extra virgin olive oil and beef tallow. I have never felt better in my life. Protein and Carbs triggers insulin, whereas fat doesn’t. Hence, a high fat low carb won’t store anywhere near as much fat.
What does he mean by you will just reduce your calories out?? If we keep eating in a deficit then how would we NOT keep losing weight? We would surely keep losing weight in a deficit no?? But again what does he mean by "you will just reduce your calories out"????
I’ve cut my daily diet down to two meals (1,500 calories total) per day, reducing the amount of carbs significantly in my meals as well as doing intermittent fasting (eating breakfast at 10am and dinner at 4pm) and I have lost 50lbs in half a year so far. The best part is that I’m not craving food despite the significant calorie reduction which has enabled me to stick to my plan without any difficulty. I’m now aiming to lose another 50lbs and run a half marathon this year.
What does he mean by you will just reduce your calories out?? If we keep eating in a deficit then how would we NOT keep losing weight? We would surely keep losing weight in a deficit no?? But again what does he mean by "you will just reduce your calories out"????
6 років тому+52
the answer - low carb (more fat), intermittent fasting
I am no expert in internal medicine, but the way Dr Fung is presenting this simple logic which entire pharma industry is denying, he deserves a Nobel price for it. 🙏
i have laser focus regardless of diet. i need the carbs for athletic performance. and yes i have tried keto, nothing special. it's all about calories in vs calories out. if you feel bad when eating carbs, you might be allergic to starch or some shit, i'm not.
What does he mean by you will just reduce your calories out?? If we keep eating in a deficit then how would we NOT keep losing weight? We would surely keep losing weight in a deficit no?? But again what does he mean by "you will just reduce your calories out"????
i watched like 10 videos on pcos and insulin resistance and was still confused , but in less than 3 minutes he explained it so simply yet brilliantly , thank you .
Diagnosed with T2D in december. Lost 45 pounds and only been able to do IF and strict Keto 80% af the time - if I had the willpower to do it 100% I would probably have lost the remaining 40 pounds I need to. No meds of any kind and A1c is now within normal range. Just wanted people to know it works.
Dr. Jason Fung I have been reading your videos for about 2 months. All explains a lot to a common person about Diabetes. THIS VIDEO IS SHORT AND STILL EXPLAINS A LOT ABOUT DIABETES VERY CLEARLY. THANK YOU FOR YOUR TIME AND EFFORT.
Quick Talks: Dr. Fung is one of the best advocates for Intermittent Fasting and very low carb diets (mainly Keto). However, I simply don't have time to watch his 30-120 minute videos. I deeply appreciate your edited summary of one of his main topics, insulin and insulin resistance... I will watch this several times to let it sink in... much better approach for many people, I hope Dr. Fung reads this.
Billder Inbaja You are right...his videos are long... however, what is the cost of NOT learning AND applying his concept? I suggest if you dont have time for your help...you wont have much time in the long run either.
Good points Darin. I do watch the long version as well, but it is very technical and too much to really absorb. With this little 3 minute condensed version, I can quickly review and reinforce the high points. I agree... if one is serious about Keto + IF, these are critical concepts.
I agree Billder! As a diabetes educator and coach I follow Dr. Fung's lectures avidly. They are a bit laborious but I force my way through them. These condensed, abridged versions serve a purpose as well, but the full meal is valuable too. I've re-watched this particular one a few times already. Thank you to the producers and Dr. Fung.
Dr. Fung has been a godsend. I tried the conventional wisdom, the counting calories and “calories in/calories out” model for decades with limited success and it was impossible to progress beyond a certain point. I’ve been putting his insight to work for over a year now and I’ve blown through past persistent plateaus and improved my body composition way more than I thought was possible. And it’s still working, unlike the conventional wisdom which consistently hit a wall about six months into it no matter how much I counted calories or exercised. It’s what you’re eating and the frequency with which you’re eating much more than the calories. The metabolic switch and controlling for insulin and other hormones and blood sugar are the key. That comes first, then being in a caloric deficit will actually be effective over time. I’m sure that I’m in a caloric deficit but I don’t count calories. I just practice time restricted eating and eat a healthy keto diet. I just focus on hormones including counter regulatory hormones like noradrenaline and glucagon, blood sugar, the metabolic switch, ketosis and hgh which is naturally upregulated early in a fast when you get the metabolic switch, insulin sensitivity, and anabolic sensitivity.
Im am not a native english do i get this right? The best way to lose fat is to keep insulin low to open the freezer. If you are on the caloric deficit but still keep the insulin high, you wont open the freezer body will just reduce calories out...with no touch of fat..even if you are on deficut? Right?
If insulin is high, you aren't going to be able to access your energy reserves which is why people with insulin resistance/diabetes struggle to lose weight even in a calorie deficit and if you've noticed, those who are taking insulin gain weight and many actually become obese, and it happens even if the person is in a calorie deficit. If you are metabolically healthy, you are likely to have good insulin sensitivity, or a metabolism that burns a lot of calories very quickly, so you get no big spike in blood sugar which means insulin doesn't need to go crazy trying to store energy, keeping it on the low end, making it easier for your body to use up the stored glucose and fat. Bottom line, a calorie deficit is effective if you have good insulin sensitivity or a beast metabolism.
@@haylslouise8428 Just wondering, cause my father is Now 67, and he has high choresterol levels and sugar. And he is trying mąkę IT lower. Lately he drop large amount of weight like 13 kg, but still cholesterol and sugar are the high side, even if that drop in weight should make insulin sensivity better...im not gettin it
@@MrJONKS a drop in weight doesn't always improve insulin sensitivity, which is why we see people who are a normal weight develop insulin resistance. It will take a while for your father's blood sugar to drop to normal levels and cholesterol also, because remember, it takes a couple of decades to go from normal, insulin resistant to diabetic, so it makes sense that it may take that long to reverse it. What does his diet consist of?
My dad is 65 and has high cholesterol. They've told him to reduce fat, which is odd considering my dad has eaten a very low fat diet for years. He eats high sugar high carb foods though which I believe caused his cholesterol to go up, and that's why I'm wondering what your dad eats?
Dr. Fung is a breath of fresh air. An honest genius with a humble demeanor. No nonsense. Makes the information easy to understand. And he is sooo right. IF all doctors know this, why haven't they done something about it instead of just telling patients to eat less exercise more ??? all of a sudden, now doctors are acting like they invented fasting and are giving TED talks. I wish Dr. Fung all success. He should get a Nobel prize for honesty and ethics.
That last bit was very interesting to me. It explains when people say if you reduce calories it doesn’t work. But that’s only if you’re eating the wrong calories. If you’re on keto and fat adapted and you reduce calories it’ll reduce insulin which means you can burn your fat. So it won’t reduce calories out even though you’re reducing calories in.
This man changed my life. He is , THE ROCK STAR OF SCIENTIFIC RESEARCH KNOWLEDGE FOR FAT AND HEALTHY LIVING. Thank you doctor, for being on the cutting edge technology of the truth. What the industry doesn't want you to know. He speaks the truth. Get it while you can before it disappears.
I thank Dr. Fung, Dr. Bikman, Dr. Lustig and other experts in the field for sharing their wealth of knowledge. I can't now imagine where I would have been had I chosen to follow the standard plan of care to treat my insulin resistance and diabetes. Just minimising my carbs and fasting did wonders for me. It was like starting up a cold engine. Thank you, thank you. Thank you!!
Yes, those stupid bodybuilders becoming some of the leanest people on the planet despite eating high carb diets. I mean, if insulin blocks all fat burning, how could they possibly do that?
I have currently made use of this unique plan *2WeightLossFast. Com* for several days already as well as the results are fantastic. They provide me a lot of energy and also suppress my urge for food, however I don`t crash whenever they wear off which I love, and they don`t cause me to feel jittery. I did absolutely nothing special on my very own diet regime and I still manage to burned my unwanted weight to 7 lbs.
Im T1d and on insulin therapy and I'm struggling to lose weight too..cuz if the only way to lose weight is by bringing down insulin thn no way for us diabetics as we have to take the correct dosage for every meal so there's no way to get stuff out of the freezer in the basement..am I making sense?
It took me 33 years and this understanding to "Have my cake and eat it to" Finally my weight stays where it's supposed to. Great analogy I really enjoyed your presentation! Thank you!
I started 18/6 intermittent fast 12/27/22 and on 1/2/2023, not even a week I lost my 1st 5lbs. I’m insulin resistant and very close to being pre- diabetic. Since the 2nd day I’ve been in mild to moderate ketosis. My goal is to reset my body and heal myself from the metabolic disorder.
Good analogy with the freezer, because just like a fat cell, the freezer cannot be over packed unless something is VERY wrong. Linoleic acid oxidation.
He's literally one of the only people saying this on youtube, everyone else says "calories in/Calories out" but coming from experience, this guy is correct. I've tried multiple times to still maintian eating sugar and things like that but just being in a caloric deficit. It worked for a few weeks but i always felt lke my progress stalled, vs when i cut out the sugar and lower my carbs it seems like the fat just falls off me.
Sure that might work for you but the problem with his message even if intentioned good (Which isn’t an excuse for misinformation) if someone finds it’s supper hard to fast and they just binge whenever they try to fast they just think we’ll I’m fucked so better not even bother If what he claimed was true then bodybuilders who eat 6 meals a day and inject insulin (because it is anabolic for muscle growth and retention) would never get shredded
@@takashi-lee3943 5 months later I lost 30 lbs from still allowing myself to eat some sugar and stuff. But maintaining a caloric deficit & focusing on a balanced diet more so than keto. You were right, although I still feel bloated at times. But i maintained more muscle this time than I did when I did keto and felt miserable for 6 months lol
I'm starting to lose weight with IF and eating less than 1500kcal a day. If I start keto I'll mks excuses or get overwhelmed and fail. But this baby step of less calories, then IF is already working. Keto will be the baby next step.
Long ago I lost a great deal of weight (70 lbs.) as I was learning about my body from the writings of Dr. Roy Walford and his work on calorie restriction and longevity. It took me 20 years of bad eating to get back over 200 lbs. again so I decided it was time to do some new research and see what I could do to both get back to my ideal weight and to help my mother to lose weight since I felt that the disease that eventually killed her was related to her being over weight. Fortunately, mostly out of instinct, I gave up sugar 20 years ago especially in my beverages and didn't return to the habit of three teaspoons in my coffee and such. I am currently in the process of fasting to get back where I should be which being 5'10" and of large bone structure I feel should be between 160 to 170 lbs. Tonight I told my mothers five siblings how I was losing weight (almost 10Kg in three weeks) and they responded with extreme concern and told me all the clichés that I was expecting and all the armature doctor advice that goes with them. I was too late to help my mother but I feel that I’m still in time to help all of them who are each at some stage or another of type-two diabetes. The catch is, none of them speak English, only Spanish. I found Dr. Fung's first book "The Obesity Code" in Spanish and will be buying them each a copy however not the new book "The Diabetes Code". When will this be available in Spanish? You've got to get this information out to the rest of the world it is too important, lives hang in the balance. If this book has been translated does anyone know where I can buy a copy? It's not on amazon. If not, when can I expect it to be available? Thanks in advance for reading this and any help you can grant me.
I have seen many of your videos and now have subscribed because you share great knowledge by talking to people in a simple to understand method with great knowledge.
This is 100% true. Preparing for my Bodybuilding competition, my coach had me eat an extremely high protein diet (to maintain muscle/reduce muscle loss), with a low proportion of carbs & fats. I went from 82kg to 67kg stage weight with 6 - 7% body fat.
What does he mean by you will just reduce your calories out?? If we keep eating in a deficit then how would we NOT keep losing weight? We would surely keep losing weight in a deficit no?? But again what does he mean by "you will just reduce your calories out"????
Life-changing information that big pharma doesn't want you to hear. Pharmaceuticals give you more insulin (making the problem worse), instead of fixing the root problem of insulin resistance. Thank you Dr. Fung!
Fasting test was @126. Dr wanted to put me on metformin. Then I discovered IF. Two week retest 117. HA! Dr wants to see me again in 6 weeks. He is worried that IF is too aggressive. I left Dr. Fung's name with him.
Nice job +John Slagle! Similar thing happen with me only I was taken off metformin. I’m never going back to taking meds either. Now that I understand how to help my body control it’s own insulin.
@chris beerad You did not get to the point. Keto/low carbs means no outside supply of glucose into your body. What body does? Start breaking down own fat as ketosis. What he did he reduced incoming carbs, exactly what needs to be done to low blood glucose. Low calories or fasting ( 0 calories) improve insulin sensitivity. The problem is we cannot live this way.
Dr Jason you are so right. I lost so much weight thanks to your explanations. I owe you so much. You are amazing, carry on the good work! you are awesome !
Point well taking. Address the insulin issue and the science of weight loss starts to make sense. Every chronic disease is in some way caused or exacerbated by hyperinsulinemia Dr. Fung is on point and doesn't pull any punches..
Literally not true at all. Daily sugar intake in the US has been declining since the late 1990's yet obesity continues to rise. Why do you think that is?
It's been working for me in the same way. Soaked chia seeds with generous amounts of tahini spooned in every day, around twice a day. It's delicious and filling.
i didn't have control over my insulin while i lost 130 lbs through intermittent fasting. i ate at a moderate carb level, with decadent desserts every other day. proof: this coming march, i'll have been at maintenance for 5 yrs. the calorie deficits are what got the weight off. the calorie balance is what keeps the weight off.
So you did intermittent fasting. ¿Would you had lost weight on the same coloric restriction diet with no IF? ¿Could it be that the IF part of the process helped lower insulin? 🤔
I do IF past month. 8/16, no food restrictions, body automatically actually said I want even more healthy food that I'm getting now:) I had few days off IF already. I do have cakes (home made) and still loosing weight. Very slowly, but my aim to do IF was the health benefit, the great feeling of having energy, better sleep, feeling fresh and definitely in better mood and closer to the God.
For most people does not work. Carbs make you starving and eating often that cause insulin resistance. Better eat good fats and feel full for long time.
Jeneric Stewart Hi Jeneric, I made my decision of give it a try for life changing since my insuline treatment is not effective and units needed are increasing steadily. Any feed back about fasting rutine? What was your approach or weekly rutine? Thanks
So the key is, eat smaller meals, and space them out to every 2 hours, so the insulin can have a quick job of processing food that you intake. Insulin can only get at unwanted fats on the body, if it doesn't have days worth of food backed up in your system. It can simply bring your body to renewal, if it's released, in a health manner, without over indulging with portions.
No. Eating several meals spaced out every two hours all day even if those meals are small is going to keep blood glucose and glycogen levels high and spike insulin depending especially on what your meals consisted of. To tap into fat stores, you need to deplete the blood glucose AND glycogen by 1) limiting the number of times you eat in a day ... typically not more than three times and no snacking in between 2) limiting how much you eat and how much carbs you eat... protein also but to a lesser extent 3) fasting.. going longer periods of time between the last meal of one day to the first meal of another day.. 12 hours minimum.. but longer will be better 4) burning blood sugar/ glygogen through exercise 5) reduce stress and get plenty of quality sleep
So, its not about the calories, its about fasting 🌹, cos when i reduced the calories and almost no carbs, i didnt loose weight at al. The fat was locked up behind a steel door in the basement. I couldnt get to it. Maybe i try your tip, by fasting and eat 1-2 times a day. And see what happends🤔
@@Tom-em8nn For sure. My mother in law just did a 13 day fast, then ate for four days and didn't like how she felt and is now on 11 days into her second fast. She is doing great. Just make sure to manage your electrolytes.
@@flowersmile123 I do a few things. Basically you just need sodium, potassium and magnesium. Dr. Berg makes a good fasting powder. I also drink chicken broth. It has a few calories but not enough to break a fast. Gives you sodium and helps with food cravings.
I did intermittent fasting and extended fasting months ago without knowing that I was 4-5 months pregnant already. I was scared that I might develop diabetes since I always crave for sweet foods. Although undiagnosed, but I had the symptoms of diabetes, hypoglycemia, sweet food addiction, I also had insomnia, lowered libido and mood swings. I guess unhealthy food products and being overweight really takes a toll on your health .What I did was i only ate thinly sliced raw cabbage, boiled eggs, some cheese to put flavor in the cabbage, cucumber, grean leafy vegetables here in my country. No coffee, no sugar, no bread, no rice, no dairy. I've lost 20 lbs in 6 weeks, from 170 lbs last year, I went to 150, that was when I was pregnant already. Now, I've given birth 3 months ago, I'm now 145 lbs, sadly I cannot do fasting in full blast since I noticed my breastmilk production gets affected..I will do it again once my baby turns 3 yrs old..but, still, even if I'm not fasting anymore and I'm back to eating rice and putting sugar on my tea, I'm 145 lbs, which is really great..im happy coz im able to maintain it despite eating some unhealthy food again..my point is, fasting healed my insulin resistance. :)
Doctor what do we do a doctor says call back to re adjust pump from giving too much insulin and then plays hide because insurance doesn't pay all the visits. And insurance doesn't let a patient pay for extra insulin visits to adjust..... So ODing on insulin daily spending 50 a week on candies to keep from bad drops
In general, I agree (based on my experience doing intermittent fasting for a couple years). My fasting insulin is super low now (about 2mcU/mL), which is good, and means that I am highly insulin sensitive. I did lose a lot of weight going from 33 BMI to 23 BMI. However, even with my low insulin levels, and continuing to be sort-of low carb and doing intermittent fasting and walking for exercise, I can't completely lose my belly fat. I think if insulin was the be-all end-all, I'd lose my belly fat, too, but alas, the diet gods are not so kind...
This is the first video i've ever seen finally say this. I've said to many friends who asked me how I lost weight. It's simple. Until you understand what insulin is and how it works you're stuffed. Then learn about other metabolic effected hormones.
I think they do, they just have a different model of understanding. The dietitians say all that matters is calories in vs calories out. This is in fact true. Dr. Fung is saying, well if you don't control your insulin, and you start cutting calories, your body will burn less calories. This is also true. What the dietitians don't say is that second part though. Your body passively burns less but also you will basically become lazy, fogbrained and unable to really get a good workout, meaning you're burning less calories overall. The calories in vs calories out thing still holds true.
@@steveryan4410 if you don’t burn more than you eat and you’re losing weight then you’re breaking the law of thermodynamics and I don’t think you’re doing that…
Can someone please answer these questions for me? What does he mean by you will just reduce your calories out?? If we keep eating in a deficit then how would we NOT keep losing weight? We would surely keep losing weight in a deficit no?? But again what does he mean by "you will just reduce your calories out"????
If you decrease your calories intake, you definitely will lose weight. Yes, your metabolism will slow down, but if you exercise regularly, there is no way in beating the law of thermodynamics. Also, lower calorie intake should equal lower insulin response because the size of your meals are smaller given that your macronutrients stay equal. You can also enhance the lower insulin response by just eating less sugar and carbs.
Our bodies are not a closed system. Thermodynamics law don't apply. Calories are not equals, proteins takes more energy to metabolize than carbs or fat. Carbs raise your insulin throught the roof. Macros matters, not calories. Cal are a side thing.
Tens of millions have tried the methods you mentioned, at the end most failed. Intermittent Fasting hasn't disappointed the people that tried it or use it as a lifestyle.
Seedzification Correct but technically calories are macros each individual macro contains calories so if we eat too much protein and carbs for example your insulin levels goes up and it causes you to gain weight not because of calories however fat is almost neutral it doesn’t create an insulin response people are throwing out the myth that too many calories make you fat when really all it is is excessive carbs and protein in the diet and high insulin the theory of calories in calories vs calories out is a deception
One flaw in Dr. Fung's reasoning: your body cannot simply "reduce the calories out". Whether your insulin is high or low, your body requires a certain amount of calories to maintain all the internal metabolic functions it needs to carry out on a daily basis. Unless insulin can suddenly change the laws of thermodynamics, these "maintenance" calories cannot be reduced. If you require 1,500 calories to keep your body alive today, you will require 1,500 calories to keep your body alive tomorrow, even if your insulin levels are elevated. So, at the end of the day, yes, insulin is very important, especially when it comes to reducing fatty liver, etc., but CICO is king. If you want to lose weight, reduce your calories. If you're making the right food choices, your insulin will come down naturally.
Consistently Controlling Calories in versus out with High protein an exercising. But consistently lowering Insulin will plateau weight loss so you have to start feeding healthy carbs with exercising to main a balance for muscle. Then Make the switch of the two a routine so you're body is aware the time you need the energy stored in muscles an the time you need to go into a energy burn out.
You should watch Dr fungs video on the myths of intermittent fasting. You do not lose muscle, I certainly have not, in fact, many people have found they gain muscle easier since fasting, especially if they do their training in the fasted state. You would also be surprised to find that your body doesn't need to be overloaded with protein, its another lie you've been told. Our ancestors were in shape, yet, they moved way more than we do, ate less than we do and they didn't have protein shakes and powders and man-made supplements, they got their protein from meat, eggs etc... yet they weren't just blobs of fat, they were actually very muscular.
This is great advice, but this is an oversimplification of body fat storage. There is another hormone called ASP (Acylation Stimulating Protein) that also encourages fat storage. In addition, stress levels and cortisol have a psychological and behavioral impact making fat-burning more complex than this simplified model.
I was always lean but could never get six pack because I was consuming too much bread, rice potatoes etc. I was also shocked to find that I had fatty liver when I was lean and athletic looking. I now understand why. I am angry with my doctor who said not to worry about the fatty liver and just cut down sugar. I could have got type II diabetes if I listened to him. I will give the IF and keto a go and see what happens.
I homeschool and I'm following a curriculum, and one of the lessons is teaching the hokey "calories in, calories out" to my 10-year-old. I'm going to briefly break down why it's hokey, and show him this Dr. Jason Fung video instead. My kids would *never* get the hormonal theory of obesity in government school.
I wish this video went on to explain how fasting helps so that I can use it to explain to people why I fast. I'm tired of trying to explain it, and this short video does such a good job of getting to the point. Sending people long ass videos isn't effective because the attention span isn't there.
Stop eating processed foods, all of them. This is what I have done and I am not over weight and still have plenty of energy for living each day. If the food has a sticker or a label, don't eat it. You will find that this will cut your carb intake dramatically and this is a good thing.
Dr. Fung is intelligent no doubt, but what I really like about him is his ability to keep it simple.
Simple? You mean cherry picked parts of studies that support his views. People do your own research, don't be a Jason Fung sheep please! If you demonize Insulin, you either know extremely little about how the body works or you are trying to sell thing to people looking to blame anything but themselves for being overweight. Jason Fung is the latter.
Paul Jansen What?? Who's selling something? Who demonized insulin? Did you read my comment? I expressed MY opinion on Dr. Fungs presentation. How you took sales and demonizing out of that is beyond me! What I "cherry picked" out of your comment is that you've COMPLICATED a simple observation.
No no I'm not talking about you at all, I'm talking about the good doctor. He cherry pics to get people on board with his ideals and makes a ton of cash from his books/videos. Sorry about that lol
Feel free to read, it's genuinely objective.

Paul Jansen Oh ok! My apologies as well. I misunderstood.
I very much enjoyed his style in this talk
In many other longer interviews he calls people idiots at a rate of maybe 10-15 times an hour
Being a doctor myself I followed your diet and changed my eating habits low carb high fat and protein not only did I lose weight got healthier even could control diabetes. Brilliant reasoning, Intelligent thinking Dr Jason.
Meher Prasanna Rokkam
What exactly did you do?
I hope you help your patients also
@Rusty you don't know what you are talking about! Sugar, refined foods, starches cause diabetes! It also causes candida yeast to over grow and become fungus in your body that causes cancer. Many are now practically being born with cancer. And cancer is becoming rampage. Diabetes is high sugar in the blood. High sugar or starch kills the good friendly bacteria in your gut! The diet is to substitute sugar to high fat for a few weeks for the transition. The body then starts to use your body fat thus losing drastic weight. You maintain eating your raw veggies salads, good fats and low meats. This is the best diet. Plus adding intermediate diet really adds to the punch of loosing weight. There some people that is keep their weight down and are extremely healthy is ONE healthy good meal a day. Great for diabetics because the constant snacking or eating forces your body to produce insulin and is not good. I met people that eat this way and are super healthy, alert, full of life.
@Rusty - check out the number of Indian Doctors you have in the US! Will give you an idea.
@chris beerad so fats has low calories? And protein? Haha
Reduced my sugar intake to less than 10 grams/day. Combined it with resistance training (3 times per week) and I eat a bit less carbs and fat, but more protein intake to gain muscle mass. Lost my belly and I look damn fit. This happened in 3 months time.
tips and tricks?
Don't need to restrict it to just 10 grams, 90 is the recommend. Aim for 40ish to 50 and youll acheive same results.
Tyson Moffat no
Did you get a trainer? I have no idea how to do resistance training, but I know it's the best way to stay strong
@@itscooltobeyou No, I bought a dumbbell set and train at home. Did some research and watched some professionals on youtube like Jeff Cavalier (athleanX) and Mike Thurston.
My basic routine is: Dumbbell floor press (chest), windshield floor wiper (abs), dumbbell skull crusher (triceps), Squats (legs), dumbbell Curl (biceps), bend over rowing (back). I do 5 sets of 10 reps for each exercise.
Most of the exercises I do are what they call 'compound' exercises so you train different body parts at once. I switch some exercises after a while to shake up things a bit like eg I will do Hammer curl instead of normal curl and eg dead lifts instead of squats.
I need to add another comment. The food industry DOES NOT MAKE MONEY OFF OF FASTING!!! nor , does the pharmaceutical industry. When, "they tell me to go left, I am going right". Thank you Doctor Fung for a way of living that is healing.
Absolutely agree 👌👌👌
Or the diet industry. God forbid people found out they don't need sugary meal replacement shakes to lose weight, or that that sports drink and energy bar in the gym does you zero good.
Big Food and Big Pharma have to keep people obese and sick to make big profits and the NHS with corrupt Senior civil servants, Corrupt, corrupt MPs are shills and colluding with big food and big pharma.
The wrong food to eat they are pushing will make and keep people obese and make them sick.
The British NHS terrible nutrition advice is proof of this.
htps://www.nhs.uk/live-well/eat-well/
"base meals on starchy foods like potatoes, bread, rice or pasta"
"Aim to eat at least 2 portions of fish a week, including 1 portion of oily fish."
"have some dairy or dairy alternatives (such as soya drinks)."
"Having a sliced banana with your "morning cereal" is an easy way to get 1 portion".
" Eating a lot of saturated fat can raise cholesterol levels in the blood, and having high cholesterolraises your risk of heart disease".

What changes did You make to accomplish your weight loss
I take breakfast at 2pm earliest, I exercise almost every (free home workouts from fitness youtubers), I avoid sugar as best as I can. Sometimes I fast for 24 hours or more. I've been living this way for over a year now and I'm keeping the weight off. Fasting is anyway the game changer, cus I also did workouts before now.

My doctor recommended this system [Go here=== *2WeightLossFast. Com* ]to me. I was looking to lose a significant amount of weight, and needed a plan. This diet book has done miracles for me and my husband! We follow the plan and both lost over 20 pounds in the first month. This is a well written book that will give you the tools you need to start eating healthier and regain control of your metabolism. I can't say enough good things about this book and the diet. This was a life changer for us!?
Intermittent fasting, keto and eating 1500kcal a day helped me lose over 100lbs
It’s the 1500 calories which worked not Keto
Annatar my bf shed 102 lbs as well. He is healthier than ever ! For people against it I guess they never tried
maybe the 1500 cal was what worked, but keto heals your metabolism, prevents craving, makes you healthier & more energy. Started for weight loss, stayed for the health benefits. keto is amazing.
@@fitnessnutritionandsoul3618 no, it's keto, 1500 total calories with 60% coming from carbs, the current SAD, increases insulin. This closes the fat burning process, no workout or food fixes these issue. Keto does. Did for me, went from 269 to 185 in a year and 4 months. You are just stating otherwise, because you've been brainwashed. And don't like it when others go against your views and ideology.
"It’s the 1500 calories which worked not Keto" BULLSHIT...did you even watch the video???? Insulin controls what you store. crissakes.
They should teach this at school
they do the fat bastards stay at home and eat all day so they miss school.
They do teach this at medical school,but there they teach the proper version. What he's neatly skipping over is that if you have insulin resistance as a result of too high blood sugar levels for too llong(type 2 diabetes) and you reduce the amount of energy you eat, then the body will pull on some of the energy it has available to cover the difference, and some of this energy will be taken from the excess energy in the blood - the blood sugar. If you eat less than you need and lose weight, blood sugar levels will go down.
When/if the blood sugar levels go down and stay down,eventually insulin sensitivity returns to more normal levels. This is why weight loss is an integral part of treating type 2 diabetes.
Yes,the body will adapt to the energy deficit by trying to reduce how much it spends, but you have some leeway. The bigger the gap between what it wants and what it has, the faster this adaptation will occur. If the deficit is smaller, the body can keep losing weight for longer before it gets upset,and you have more space to make more changes.
So he's basically giving you half the truth in order to push his view,which is troublesome.
They should teach alot of things at school but they don't
They teach actual science in school, not this nonsense.
this is highschool biology where I live.. not with these metaphors ofc
if you mean US school then yeah, they should teach a LOT more things there from what I've heard
He explained it so well, entire UA-cam fitness icons couldn’t
Jason Fung is a charlatan and not even a qualified nutritionist, he's a cancer doctor.
lmao sure
I am 74 YO and began the 18/6 fast at the beginning of this year and find it so easy to perform. No counting calories or special, expensive foods. Have lost about 1/2 pound per day. Tried going on a 48 hour fast and was successful, so may add it periodically.
I try to get in a 3 to 5 mile walk in every day, as well. The key is PATIENCE. If I can maintain this fat burning rate, I am looking forward to warmer weather and biking season and will see how that goes.
That fridge and freezer analogy really rings the bell! Perfection!

I did 16/8 intermittent fasting and finally I'm no longer insulin resistant :D. My insulin levels were constantly high for years, and took me 5-6 months of IF to finally control that goddamn hormone! I can't describe how happy I am ;_;
Congratulations so happy for you💜💜+ what did you eat?
@@nottoday4820 I ate lots of white meat and healthy fats (from nuts and seeds), along with whole wheat bread and low glicemic fruits such as berries. Twice a week a had a small portion of brown rice or pasta as a side dish. This is what worked for me tho and I'm still doing it, a professional should give you a complete guide according to your needs 😉
So, it's not a permanent condition? Damn, I just learned that I'm insulin resistant 15 min ago and I had a epiphany about how I hurt and damaged my body for so long. I'm pretty fit but not as healthy as I should. Been doing IF but I'll start incorporate low carb too. Any tips to make the process smoother?
@@beatriceladouce965 excersice is your best ally!! I do cardio and resistance training 5days a week. If you crave sweet treats like I do, try to replace sugar with tagatose for baking/cooking. Tagatose is safe and has minimal effect on your insulin levels. I don't know what else I can say, but good luck!! You can avoid type 2 diabetes by changing what you eat ☺️
I figure it’s going to take me at least that long. I know it’s going to turn around. My problem is I do 20:4 fasting and I am not hungry at ALL. When I do eat my one meal in the afternoon ( around 3pm) I’m stuffed and when I put it in my calculator app...I rarely go over 1,000 calories.
This video was the one that opened my eyes, changed my life, over a year ago. After watching this, and subsequently "Fasting as a Therapeutic Option for Weight Loss" I looked my wife in the eye and said "I finally understand. I'm going to lose weight and keep it off, I will never be overweight again" That was over a year ago and I am finally, for the first time since I was a young child, I feel healthy. I'd managed to lose weight before but never felt healthy and never kept it off until now.
Glad you did it bro
At the end of the video, what does he mean by you will just reduce your calories out??
Congrats you did it 👏🏻. I hope one day I will achieve that 🥺🙏🏻
*Intermittent Fasting + Low Carb (and very low to no sugar) is KEY to weight loss!* I lost 100lbs only eating red meat, salmon, eggs, berries, Kefir and cooking in extra virgin olive oil and beef tallow. I have never felt better in my life. Protein and Carbs triggers insulin, whereas fat doesn’t. Hence, a high fat low carb won’t store anywhere near as much fat.
What does he mean by you will just reduce your calories out?? If we keep eating in a deficit then how would we NOT keep losing weight? We would surely keep losing weight in a deficit no?? But again what does he mean by "you will just reduce your calories out"????
How about caloric deficit? You just eat less calories. Thats physics.
I’ve cut my daily diet down to two meals (1,500 calories total) per day, reducing the amount of carbs significantly in my meals as well as doing intermittent fasting (eating breakfast at 10am and dinner at 4pm) and I have lost 50lbs in half a year so far.
The best part is that I’m not craving food despite the significant calorie reduction which has enabled me to stick to my plan without any difficulty. I’m now aiming to lose another 50lbs and run a half marathon this year.
WOW 🤩

Good for you! I'm happy for you.

Dr. Jason Fung I have been reading your videos for about 2 months. All explains a lot to a common person about Diabetes. THIS VIDEO IS SHORT AND STILL EXPLAINS A LOT ABOUT DIABETES VERY CLEARLY. THANK YOU FOR YOUR TIME AND EFFORT.
I looked to see if Dr Jason Fung has ever done a TEDTalk...no. The man is just TOO knowledgeable even for them. If he is talking I am watching!
If you like TED Talks you should check out Sam Hyde's TED Talk. Best I've seen.
He's wrong on so many levels but there again I'd expect that from a cancer doctor speaking about nutrition.
Quick Talks: Dr. Fung is one of the best advocates for Intermittent Fasting and very low carb diets (mainly Keto). However, I simply don't have time to watch his 30-120 minute videos. I deeply appreciate your edited summary of one of his main topics, insulin and insulin resistance... I will watch this several times to let it sink in... much better approach for many people, I hope Dr. Fung reads this.
Billder Inbaja
Thanks for the comment! I'm really glad it was valuable for you
Billder Inbaja You are right...his videos are long... however, what is the cost of NOT learning AND applying his concept? I suggest if you dont have time for your help...you wont have much time in the long run either.
Good points Darin. I do watch the long version as well, but it is very technical and too much to really absorb. With this little 3 minute condensed version, I can quickly review and reinforce the high points. I agree... if one is serious about Keto + IF, these are critical concepts.
YES DR. FUNG HERE I READ IT WHAT ELSE DO YOU WANT??
i suggest you find the time to watch the longer videos and actually learn properly something which is obviously important to you.
I agree Billder! As a diabetes educator and coach I follow Dr. Fung's lectures avidly. They are a bit laborious but I force my way through them. These condensed, abridged versions serve a purpose as well, but the full meal is valuable too. I've re-watched this particular one a few times already. Thank you to the producers and Dr. Fung.
Dr. Fung has been a godsend. I tried the conventional wisdom, the counting calories and “calories in/calories out” model for decades with limited success and it was impossible to progress beyond a certain point. I’ve been putting his insight to work for over a year now and I’ve blown through past persistent plateaus and improved my body composition way more than I thought was possible. And it’s still working, unlike the conventional wisdom which consistently hit a wall about six months into it no matter how much I counted calories or exercised. It’s what you’re eating and the frequency with which you’re eating much more than the calories. The metabolic switch and controlling for insulin and other hormones and blood sugar are the key. That comes first, then being in a caloric deficit will actually be effective over time. I’m sure that I’m in a caloric deficit but I don’t count calories. I just practice time restricted eating and eat a healthy keto diet. I just focus on hormones including counter regulatory hormones like noradrenaline and glucagon, blood sugar, the metabolic switch, ketosis and hgh which is naturally upregulated early in a fast when you get the metabolic switch, insulin sensitivity, and anabolic sensitivity.
Im am not a native english do i get this right? The best way to lose fat is to keep insulin low to open the freezer. If you are on the caloric deficit but still keep the insulin high, you wont open the freezer body will just reduce calories out...with no touch of fat..even if you are on deficut? Right?
Right
If insulin is high, you aren't going to be able to access your energy reserves which is why people with insulin resistance/diabetes struggle to lose weight even in a calorie deficit and if you've noticed, those who are taking insulin gain weight and many actually become obese, and it happens even if the person is in a calorie deficit. If you are metabolically healthy, you are likely to have good insulin sensitivity, or a metabolism that burns a lot of calories very quickly, so you get no big spike in blood sugar which means insulin doesn't need to go crazy trying to store energy, keeping it on the low end, making it easier for your body to use up the stored glucose and fat. Bottom line, a calorie deficit is effective if you have good insulin sensitivity or a beast metabolism.
@@haylslouise8428 Just wondering, cause my father is Now 67, and he has high choresterol levels and sugar. And he is trying mąkę IT lower. Lately he drop large amount of weight like 13 kg, but still cholesterol and sugar are the high side, even if that drop in weight should make insulin sensivity better...im not gettin it
@@MrJONKS a drop in weight doesn't always improve insulin sensitivity, which is why we see people who are a normal weight develop insulin resistance. It will take a while for your father's blood sugar to drop to normal levels and cholesterol also, because remember, it takes a couple of decades to go from normal, insulin resistant to diabetic, so it makes sense that it may take that long to reverse it. What does his diet consist of?
My dad is 65 and has high cholesterol. They've told him to reduce fat, which is odd considering my dad has eaten a very low fat diet for years. He eats high sugar high carb foods though which I believe caused his cholesterol to go up, and that's why I'm wondering what your dad eats?
Dr. Fung is a breath of fresh air. An honest genius with a humble demeanor. No nonsense. Makes the information easy to understand. And he is sooo right. IF all doctors know this, why haven't they done something about it instead of just telling patients to eat less exercise more ??? all of a sudden, now doctors are acting like they invented fasting and are giving TED talks. I wish Dr. Fung all success. He should get a Nobel prize for honesty and ethics.
Epic explanation. Really simplifies complex processes for the average person (me) to understand.
That last bit was very interesting to me. It explains when people say if you reduce calories it doesn’t work. But that’s only if you’re eating the wrong calories. If you’re on keto and fat adapted and you reduce calories it’ll reduce insulin which means you can burn your fat. So it won’t reduce calories out even though you’re reducing calories in.
This man changed my life. He is , THE ROCK STAR OF SCIENTIFIC RESEARCH KNOWLEDGE FOR FAT AND HEALTHY LIVING. Thank you doctor, for being on the cutting edge technology of the truth. What the industry doesn't want you to know. He speaks the truth. Get it while you can before it disappears.

Not the most complicated concept on a biological level, but Dr. Fung does a great job of making this idea accessible to a larger audience
As a diabetic on an insulin pump I agree 100%. I have great control but the weight issue is a tough one. Low carbs and embrace a good salad
Im T1d and on insulin therapy and I'm struggling to lose weight too..cuz if the only way to lose weight is by bringing down insulin thn no way for us diabetics as we have to take the correct dosage for every meal so there's no way to get stuff out of the freezer in the basement..am I making sense?
It took me 33 years and this understanding to "Have my cake and eat it to" Finally my weight stays where it's supposed to. Great analogy I really enjoyed your presentation! Thank you!

Sugar is main key in weight loss
He's literally one of the only people saying this on youtube, everyone else says "calories in/Calories out" but coming from experience, this guy is correct. I've tried multiple times to still maintian eating sugar and things like that but just being in a caloric deficit. It worked for a few weeks but i always felt lke my progress stalled, vs when i cut out the sugar and lower my carbs it seems like the fat just falls off me.
Sure that might work for you but the problem with his message even if intentioned good (Which isn’t an excuse for misinformation) if someone finds it’s supper hard to fast and they just binge whenever they try to fast they just think we’ll I’m fucked so better not even bother
If what he claimed was true then bodybuilders who eat 6 meals a day and inject insulin (because it is anabolic for muscle growth and retention) would never get shredded
@@takashi-lee3943 5 months later I lost 30 lbs from still allowing myself to eat some sugar and stuff. But maintaining a caloric deficit & focusing on a balanced diet more so than keto. You were right, although I still feel bloated at times. But i maintained more muscle this time than I did when I did keto and felt miserable for 6 months lol
I'm starting to lose weight with IF and eating less than 1500kcal a day. If I start keto I'll mks excuses or get overwhelmed and fail. But this baby step of less calories, then IF is already working. Keto will be the baby next step.
That was explained so we'll. Thank you
Long ago I lost a great deal of weight (70 lbs.) as I was learning about my body from the writings of Dr. Roy Walford and his work on calorie restriction and longevity. It took me 20 years of bad eating to get back over 200 lbs. again so I decided it was time to do some new research and see what I could do to both get back to my ideal weight and to help my mother to lose weight since I felt that the disease that eventually killed her was related to her being over weight. Fortunately, mostly out of instinct, I gave up sugar 20 years ago especially in my beverages and didn't return to the habit of three teaspoons in my coffee and such. I am currently in the process of fasting to get back where I should be which being 5'10" and of large bone structure I feel should be between 160 to 170 lbs. Tonight I told my mothers five siblings how I was losing weight (almost 10Kg in three weeks) and they responded with extreme concern and told me all the clichés that I was expecting and all the armature doctor advice that goes with them. I was too late to help my mother but I feel that I’m still in time to help all of them who are each at some stage or another of type-two diabetes.
The catch is, none of them speak English, only Spanish. I found Dr. Fung's first book "The Obesity Code" in Spanish and will be buying them each a copy however not the new book "The Diabetes Code". When will this be available in Spanish? You've got to get this information out to the rest of the world it is too important, lives hang in the balance. If this book has been translated does anyone know where I can buy a copy? It's not on amazon. If not, when can I expect it to be available? Thanks in advance for reading this and any help you can grant me.
I have seen many of your videos and now have subscribed because you share great knowledge by talking to people in a simple to understand method with great knowledge.
Dr Fung, is AWESOME!
This is 100% true. Preparing for my Bodybuilding competition, my coach had me eat an extremely high protein diet (to maintain muscle/reduce muscle loss), with a low proportion of carbs & fats. I went from 82kg to 67kg stage weight with 6 - 7% body fat.
Amazing stuff! Congrats!
how to lose stubborn belly fat?
At the end of the video, what does he mean by you will just reduce your calories out??
What does he mean by you will just reduce your calories out?? If we keep eating in a deficit then how would we NOT keep losing weight? We would surely keep losing weight in a deficit no?? But again what does he mean by "you will just reduce your calories out"????
Life-changing information that big pharma doesn't want you to hear. Pharmaceuticals give you more insulin (making the problem worse), instead of fixing the root problem of insulin resistance. Thank you Dr. Fung!
Fasting test was @126. Dr wanted to put me on metformin. Then I discovered IF. Two week retest 117. HA! Dr wants to see me again in 6 weeks. He is worried that IF is too aggressive. I left Dr. Fung's name with him.
Nice job +John Slagle! Similar thing happen with me only I was taken off metformin. I’m never going back to taking meds either. Now that I understand how to help my body control it’s own insulin.
John Slagle your FASTING was 126 and he was gonna put u on metformin? I woulda told him where he can stuff that poison!
@chris beerad It's mean a whole hell of alot to him!
@chris beerad You did not get to the point. Keto/low carbs means no outside supply of glucose into your body. What body does? Start breaking down own fat as ketosis. What he did he reduced incoming carbs, exactly what needs to be done to low blood glucose. Low calories or fasting ( 0 calories) improve insulin sensitivity. The problem is we cannot live this way.
How's it going now?
Dr Jason you are so right. I lost so much weight thanks to your explanations. I owe you so much. You are amazing, carry on the good work! you are awesome !
Point well taking. Address the insulin issue and the science of weight loss starts to make sense. Every chronic disease is in some way caused or exacerbated by hyperinsulinemia Dr. Fung is on point and doesn't pull any punches..
Literally not true at all. Daily sugar intake in the US has been declining since the late 1990's yet obesity continues to rise. Why do you think that is?
I had to lose weight 3 times in my life and I succeeded easily the same way. No carbs, a lot of proteins, good fat (cashew, nuts etc).
It's been working for me in the same way. Soaked chia seeds with generous amounts of tahini spooned in every day, around twice a day. It's delicious and filling.
i didn't have control over my insulin while i lost 130 lbs through intermittent fasting. i ate at a moderate carb level, with decadent desserts every other day. proof: this coming march, i'll have been at maintenance for 5 yrs. the calorie deficits are what got the weight off. the calorie balance is what keeps the weight off.
Jeneric Stewart facts
So you did intermittent fasting.
¿Would you had lost weight on the same coloric restriction diet with no IF?
¿Could it be that the IF part of the process helped lower insulin? 🤔
I do IF past month. 8/16, no food restrictions, body automatically actually said I want even more healthy food that I'm getting now:) I had few days off IF already. I do have cakes (home made) and still loosing weight. Very slowly, but my aim to do IF was the health benefit, the great feeling of having energy, better sleep, feeling fresh and definitely in better mood and closer to the God.
For most people does not work. Carbs make you starving and eating often that cause insulin resistance. Better eat good fats and feel full for long time.
Jeneric Stewart Hi Jeneric, I made my decision of give it a try for life changing since my insuline treatment is not effective and units needed are increasing steadily. Any feed back about fasting rutine? What was your approach or weekly rutine? Thanks
Thanks for this explanation, now can you please tell us how to control insulin in order to lose weight healthily ??
The first physician that I know of to breakdown the process of weight dynamics.
This video + all Dr. Berg videos on insulin are all I needed in my life to keep my weight under control
Thanks for the short video. Straight to the point.
Best explanation I've heard and even understood . Thank you very, very much.
So the key is, eat smaller meals, and space them out to every 2 hours, so the insulin can have a quick job of processing food that you intake. Insulin can only get at unwanted fats on the body, if it doesn't have days worth of food backed up in your system. It can simply bring your body to renewal, if it's released, in a health manner, without over indulging with portions.
No. Eating several meals spaced out every two hours all day even if those meals are small is going to keep blood glucose and glycogen levels high and spike insulin depending especially on what your meals consisted of. To tap into fat stores, you need to deplete the blood glucose AND glycogen by
1) limiting the number of times you eat in a day ... typically not more than three times and no snacking in between
2) limiting how much you eat and how much carbs you eat... protein also but to a lesser extent
3) fasting.. going longer periods of time between the last meal of one day to the first meal of another day.. 12 hours minimum.. but longer will be better
4) burning blood sugar/ glygogen through exercise
5) reduce stress and get plenty of quality sleep
Excellent. So very well presented
thankyou and well done to the person who edited this !!
So, its not about the calories, its about fasting 🌹, cos when i reduced the calories and almost no carbs, i didnt loose weight at al. The fat was locked up behind a steel door in the basement. I couldnt get to it. Maybe i try your tip, by fasting and eat 1-2 times a day. And see what happends🤔
I hope it worked out for you. I've done a lot of 40 hour fasts and it works. My wife did an 11 day fast and I could almost see her losing weight.
@@smithtimothy93 11 day fast? That's insane.. Of course you can see her losing weight :D Her body is eating her from the inside
@@Tom-em8nn For sure. My mother in law just did a 13 day fast, then ate for four days and didn't like how she felt and is now on 11 days into her second fast. She is doing great. Just make sure to manage your electrolytes.
@@smithtimothy93 How do you manage your electrolytes while fasting?
@@flowersmile123 I do a few things. Basically you just need sodium, potassium and magnesium. Dr. Berg makes a good fasting powder. I also drink chicken broth. It has a few calories but not enough to break a fast. Gives you sodium and helps with food cravings.
I would like to get to know the opinion of Dr. Fung about Ozempic, Wegovy etc. Does this interfer with his idea??? Thanks for any input
I did intermittent fasting and extended fasting months ago without knowing that I was 4-5 months pregnant already. I was scared that I might develop diabetes since I always crave for sweet foods. Although undiagnosed, but I had the symptoms of diabetes, hypoglycemia, sweet food addiction, I also had insomnia, lowered libido and mood swings. I guess unhealthy food products and being overweight really takes a toll on your health .What I did was i only ate thinly sliced raw cabbage, boiled eggs, some cheese to put flavor in the cabbage, cucumber, grean leafy vegetables here in my country. No coffee, no sugar, no bread, no rice, no dairy. I've lost 20 lbs in 6 weeks, from 170 lbs last year, I went to 150, that was when I was pregnant already. Now, I've given birth 3 months ago, I'm now 145 lbs, sadly I cannot do fasting in full blast since I noticed my breastmilk production gets affected..I will do it again once my baby turns 3 yrs old..but, still, even if I'm not fasting anymore and I'm back to eating rice and putting sugar on my tea, I'm 145 lbs, which is really great..im happy coz im able to maintain it despite eating some unhealthy food again..my point is, fasting healed my insulin resistance. :)
This is the best explanation I’ve ever heard
Great explanation Doctor. I'm introducing my husband, a type 2 diabetic) to the ketogenic way of eating.
Is ur hubby getting better from diabetic now
Metformin can help reduce appetite. High blood insulin can fuel appetite.
Doctor what do we do a doctor says call back to re adjust pump from giving too much insulin and then plays hide because insurance doesn't pay all the visits. And insurance doesn't let a patient pay for extra insulin visits to adjust.....
So ODing on insulin daily spending 50 a week on candies to keep from bad drops
In general, I agree (based on my experience doing intermittent fasting for a couple years). My fasting insulin is super low now (about 2mcU/mL), which is good, and means that I am highly insulin sensitive. I did lose a lot of weight going from 33 BMI to 23 BMI. However, even with my low insulin levels, and continuing to be sort-of low carb and doing intermittent fasting and walking for exercise, I can't completely lose my belly fat. I think if insulin was the be-all end-all, I'd lose my belly fat, too, but alas, the diet gods are not so kind...
Same here. Lost ton of weight but still have belly fat. Oh well. Still great approach if you ask me!
This is the first video i've ever seen finally say this. I've said to many friends who asked me how I lost weight. It's simple. Until you understand what insulin is and how it works you're stuffed. Then learn about other metabolic effected hormones.
💯
I find it disheartening that most Registered Dietitians don’t agree with his views.
I think they do, they just have a different model of understanding.
The dietitians say all that matters is calories in vs calories out. This is in fact true. Dr. Fung is saying, well if you don't control your insulin, and you start cutting calories, your body will burn less calories. This is also true. What the dietitians don't say is that second part though. Your body passively burns less but also you will basically become lazy, fogbrained and unable to really get a good workout, meaning you're burning less calories overall. The calories in vs calories out thing still holds true.
@Sarcrai and when you burn hormones you go lower calories and lose fat
@Sarcrai exactly the same calorie of donut and same calorie of veggies are two different things on our insulin..the prior is dangerous
Brilliant. So if someone is eating very little and exercising and not losing weight should they get their insulin level checked by doctors?
Fascinating
Excellent analogy of the two food storage mechanisms. Now I finally have a way to explain to people why I fast.
Great analogy, I am living proof that I eat over my caloric goal daily, minus the bread, pasta and sugar, and is still dropping weight!
Same.. My wife, cant believe it,,i didn't do any exercise..just this diet change, dropped 2 sizes.. No she says u must burn more than u eat..
@@steveryan4410 if you don’t burn more than you eat and you’re losing weight then you’re breaking the law of thermodynamics and I don’t think you’re doing that…
Hahaha what. You think you're eating in a surplus of energy but you're losing weight? Have you just denied the physical laws of energy balance?!
At the end of the video, what does he mean by you will just reduce your calories out??
Can someone please answer these questions for me? What does he mean by you will just reduce your calories out?? If we keep eating in a deficit then how would we NOT keep losing weight? We would surely keep losing weight in a deficit no?? But again what does he mean by "you will just reduce your calories out"????
This is the first video of IF I watched ... and Im glad. Thanks Dr Fung
Beautifully logical and simply expressed ... as always from Dr Fung. Excellent.
Very simple way of teaching. Thank you Dr. Please can you help me more on weight loss.
If you decrease your calories intake, you definitely will lose weight. Yes, your metabolism will slow down, but if you exercise regularly, there is no way in beating the law of thermodynamics. Also, lower calorie intake should equal lower insulin response because the size of your meals are smaller given that your macronutrients stay equal. You can also enhance the lower insulin response by just eating less sugar and carbs.
Our bodies are not a closed system. Thermodynamics law don't apply. Calories are not equals, proteins takes more energy to metabolize than carbs or fat. Carbs raise your insulin throught the roof. Macros matters, not calories. Cal are a side thing.
Coconut oil raises metabolism
Tens of millions have tried the methods you mentioned, at the end most failed. Intermittent Fasting hasn't disappointed the people that tried it or use it as a lifestyle.
Seedzification Correct but technically calories are macros each individual macro contains calories so if we eat too much protein and carbs for example your insulin levels goes up and it causes you to gain weight not because of calories however fat is almost neutral it doesn’t create an insulin response people are throwing out the myth that too many calories make you fat when really all it is is excessive carbs and protein in the diet and high insulin the theory of calories in calories vs calories out is a deception
One flaw in Dr. Fung's reasoning: your body cannot simply "reduce the calories out". Whether your insulin is high or low, your body requires a certain amount of calories to maintain all the internal metabolic functions it needs to carry out on a daily basis. Unless insulin can suddenly change the laws of thermodynamics, these "maintenance" calories cannot be reduced. If you require 1,500 calories to keep your body alive today, you will require 1,500 calories to keep your body alive tomorrow, even if your insulin levels are elevated. So, at the end of the day, yes, insulin is very important, especially when it comes to reducing fatty liver, etc., but CICO is king. If you want to lose weight, reduce your calories. If you're making the right food choices, your insulin will come down naturally.
Reducing the calories out means lowering your metabolism. Lots of animals do it (e.g. hibernation) without changing the laws of thermodynamics.
I thought it read insults like people being mean to you make you lose weight
tonymlealv 😁
Lmao
Consistently Controlling Calories in versus out with High protein an exercising. But consistently lowering Insulin will plateau weight loss so you have to start feeding healthy carbs with exercising to main a balance for muscle. Then Make the switch of the two a routine so you're body is aware the time you need the energy stored in muscles an the time you need to go into a energy burn out.
You do not need carbs. There is no healthy carbs. Your body treats it as if you just take 20 spoons of sugar and turns into fat
You should watch Dr fungs video on the myths of intermittent fasting. You do not lose muscle, I certainly have not, in fact, many people have found they gain muscle easier since fasting, especially if they do their training in the fasted state. You would also be surprised to find that your body doesn't need to be overloaded with protein, its another lie you've been told. Our ancestors were in shape, yet, they moved way more than we do, ate less than we do and they didn't have protein shakes and powders and man-made supplements, they got their protein from meat, eggs etc... yet they weren't just blobs of fat, they were actually very muscular.
This is great advice, but this is an oversimplification of body fat storage. There is another hormone called ASP (Acylation Stimulating Protein) that also encourages fat storage. In addition, stress levels and cortisol have a psychological and behavioral impact making fat-burning more complex than this simplified model.
On a short term basis you are right, but the long term results of lowering Insulin with Intermittent fasting are pretty convincing.
How about type 1 diabetes persons loosing weight-insulin!
Also, for more technical data re autophagy the NCBI website has a search engine - just type in "autophagy".
Love this analogy!
I was always lean but could never get six pack because I was consuming too much bread, rice potatoes etc. I was also shocked to find that I had fatty liver when I was lean and athletic looking. I now understand why. I am angry with my doctor who said not to worry about the fatty liver and just cut down sugar. I could have got type II diabetes if I listened to him. I will give the IF and keto a go and see what happens.
I homeschool and I'm following a curriculum, and one of the lessons is teaching the hokey "calories in, calories out" to my 10-year-old. I'm going to briefly break down why it's hokey, and show him this Dr. Jason Fung video instead. My kids would *never* get the hormonal theory of obesity in government school.
So easily explained....
Most brilliant doctor of the decade.
Yep....Totally confused now..
I wish this video went on to explain how fasting helps so that I can use it to explain to people why I fast. I'm tired of trying to explain it, and this short video does such a good job of getting to the point. Sending people long ass videos isn't effective because the attention span isn't there.
Stop eating processed foods, all of them. This is what I have done and I am not over weight and still have plenty of energy for living each day. If the food has a sticker or a label, don't eat it. You will find that this will cut your carb intake dramatically and this is a good thing.
yeah I know what you mean but even a bag of apples has a sticker on it where I live...
