The Obesity Epidemic, Explained
Вставка
- Опубліковано 27 лип 2024
- Dr. Jason Fung explains how the 1977 dietary guidelines led to the obesity epidemic. The Dietary Guidelines for Americans changed the way Americans ate, advising us to eat more carbs and less fat to prevent heart disease, but this lead to weight gain. When we gained weight, we were then told it was our own fault. Check out my blog at / drjasonfung

Need more. We sat on the couch watching TV instead of going to the gym.

You Sir, changed my life and way of thinking, I am also a MD and I have to say ...medicine school does not teach us these things. I am 29 years old and have had issues with my body weight all my life until 3 years ago ( and also insulin resistance with a HOMA Index of a prediabetic) when I discovered your lectures and Dr Lustig's and then everything changed. I have been doing IF in the OMAD style and lately also keto , exercising and changing my habits and I have to say, your body changes, your craving change, your way of seeing food changes ...and of course you loose weight and feel better. Now I am trying to teach my close one to change their way of eating and understanding food BUT the 3 meals a day and 2 snacks mentality is so well implanted in our heads...it's unbelievable ! People look at me like I'm crazy...
When I think back to all of the abuse that I have received, over the past 25 years, because I was "told" that my obesity was my lack of willpower I want to scream.
I am now eating fats to satiety, with IF, and am down 35 pounds in 90 days.
The food industry blames the individual while they cause metabolic disorders. Just like they blamed all the excess packaging they use on "litterbugs" in the 70s.

Congratulations!!! Keep it up you’re doing so great! Nobody deserves less respect for their weight, I understand people being against Health at Every Size or movements that encourage overweight people not to change with no regard to the health implications, but individuals who are simply trying to live their lives never deserve to be disrespected for their weight. I’m sorry that happened to you.
What did you avoid eating and what did you eat?
Are we allowed bullet proof coffee during intermittent fasting?
@@thetree7694 best to kick the caffeine addiction.
I will bow to Dr. Fung forever because he says it outloud... they lied to us, they told us to do the exact thing that would make weight loss very hard and then, they blamed us. Fung blew the whistle.
After battling weight my whole life, years ago I did enough research to realize there was something wrong with my leptin/ghrelin hormones, because I never felt full. I could eat ridiculous amounts of food and still want more. It wasn’t until last year, when I discovered Dr. Fung, that I realized I had to power to correct my body’s leptin resistance by fasting. Dr. Fung is changing my life, and I am so very grateful. ♥️
~ Interesting... 👍
I overeat when I'm tired, I have a mental illness, & I tend to overeat when I'm really depressed. I'm just eating less calorie dense food. Dry boxed cereal is my crack.
Also check calorie density chart. Sounds like u were eating lotsa rich food!
Same I also struggle with emotional eating but IT corrected that, I am not a slave to food anymore
Same. I never felt full ever in my life. I didn't even know how it felt to not feel hungry or to feel satiated until I tried a low carb diet. I remember being soo happy because it felt different for the first time in my life. Thanks to Dr. Fung!
I am eating once (keto diet) only every 3days and my fat is flying away ! Thanks a lot Dr Jason Fung and Dr Eric Berg !! I owe you this success !
EVERY grad, undergrad as well as med student should be required to hear this lecture. It would rock the world.
We need to get to them before they become complacent and lazy or obligated to be big food and big pharmaceutical companies!
I'm not a medical student, just an obese person trying to lose weight,....and this information is all out there! All you have to do it read the studies. It's not hard to find.
@@Sassifrass7 no it's not hard to find but overcoming education, biases and just plain yummy carb addiction is hard for even the medical community.
whoa never thought of that
@@Sassifrass7 You're right the information is available.
However, it's rare to find a physician who advises fasting and Ketogenesis.
In my case, I found this information via Mercola/Fung.
I've been using intermittent fasting with a Ketogenic diet for the past 7 weeks.
When I started, I was 172 lbs. I'm 6 feet tall.
Today I'm 155 lbs.
I don't do this because I'm obese. I do this because I am reversing Diabetes.
It's working.
I work in cardiovascular surgery where about 9/10 patients have high glucose. I started LCHF, about 4 years ago, and the weight fell off. A few anesthesiologist asked me what I was doing, and I told them. NONE of them said anything negative. They just smiled, and nodded. Now I've started the intermittent fasting too. It's a lot easier than I thought, and I'll never go back to carbs, hunger, and being overweight. I'm glad I found Dr. Fung, I'm subbing!
What is LCHF?
@@shelleydavis5231 low carb high fat
I eat about 80 percent whole grain carbs and I have a 6 pack. I eat huge amounts too and I don't fast. I am not just a person with lucky genes. The fact is that cookies and cakes are not real carbs. Oats, wheatberries and brown rice are real carbs.
checl out Dr. Eric Berg on youtube
I got fat eating low fat to lower my cholesterol on the advice of my doctor. My cholesterol went up from 220 to 297 and I gained 60 pounds. Many doctors, including mine, are still pushing the low fat, limit saturated fats diet. I stopped listening to this bunk.
Don't listen to doctors that know nothing about nutrition and have logos from pharmaceutical companies all over their offices. It is in their best interest to keep you sick.
Because u were eating lotsa refined carbohydrates & sugars. U raised your insulin levels!
@@jgrysiak6566 Yes...had no idea at the time. It was difficult to lose the weight too b/c I joined WW who also pushed low fat no fat food, using a points system. I'd eat pretzels and fat free yogurt b/c they were 1 point, , thinking I was doing myself a favor. I was hungry all the time b/c of the refined carbs/sugars and very little fat which is satiating. And sadly many doctors are still promoting the avoidance of fat.
Just going HFLC, IF and no processed food has brought my husband’s blood glucose so low, we had to stop all Insulin and 1 oral diabetic med!! In 3 weeks!! Thank you Dr. Fung.
Hi…just wondering if the result lasted 3 years, if you don’t mind.
Dr. Fung, I feel set free. I've thought it was my fault forever. Now I see it's just been about using the wrong sources of fuel for my body. I've been adopting your ideas day by day, doing the IF and reducing refined carbs, and I feel so much better. You are much appreciated!
“ Dr Fung “ is our Angel of Reversing T2. I’m reversed from 12.2 down to a1c of 6. Deeply grateful !
Yes! Dr Fung is a GOD SEND! My A1c two years ago was 12.7! I found out about Dr Fung and intermittent fasting about two months after being diagnosed. My current A1c is 6.8 and going down at every 3 month check. Hopefully I'll reach my goal of 5.7 in a few months and be diabetes free! I do the 16/8 fasting regimen every day and try to keep total daily carbs to no more than 30g a day. Learning about a ketogenic diet and intermittent fasting has literally brought me from the point of no return. I am forever grateful for a "conventional " medical doctor speaking real truth. I put conventional in quotations because Dr Fung is anything but. He's speaking truth to light and no pill can cure a dietary disease. 👊👊👊
Why is Dr Fung in quotes? Why doesn't he UA-cam ❤ any of these glowing comments? So many sources of confusion.
Congratulations!
This is so refreshing to hear. Especially the part that obesity is not based on your genetics.
Fortunately,growing up,both parents insisted on butter and my father never used Crisco....only lard...
i make my own tallow, eat mainly meats, fast 18/6 daily fast 42 hours twice a week no weight issues here.
Lol
Thank you! Your book "The Obesity Code" started me onto understanding and reversing my lifelong obesity, uncontrollable hunger, and people's prejudice toward me because of the obesity.
140lbs down since last September, Keto and Intermittent fasting is my path... Dr Fung is saving lives
Damn that's great. I'm trying to decide on 16-8, 20-4, or longer term fast schedule myself.
@@RonaldMcPaul If I may add some advise, don't be rigid in a schedule...mix it up and keep your body guessing. Feast some days, fast others and time constraint the rest. Your body will tell you what type of day it is.
Wow that's huge. There might be something here after all. I'm fasting for the first time today ~20 hours. Maybe get rid of the beer belly.
@@RonaldMcPaul u don't need any pattern, you yourself is a pattern. Sometime I feel like I can go for 2 days without eating (water fasting only, and yes, I actually did), and sometime its really hard for me to go 16-8 . Listen to your body instead, you are unique.
What are the most important/common foods you eat? Congrats to you!
I've said "Dr. Jason Fung" to my doctor so many times she finally wrote his name down. Hope she does her research.
Doctor to Doctor
she wont, . . . lol, bcoz they r doctrinated that way
You should probably add Cole Robinson as well, but he might give her a heart attack lol.
Another patient comes and begs to watch Kardashians, do I listen every moron now? I beg you to read Idiot, Karamazov Brothers, Master and Margarita first, but you will not do... You like youtube education more..
Your Doctor wrote it down to shut you up.
Dr. Fung is the most important doctor of our time. Just as people in the 1800s claimed to be "Banting" for their weight and health, modern society will turn to "Funging".
Watching this over a big ass bowl of chicken bone broth after day 7 on Keto & IF (18-20 hours). Some days two light meals, most days OMAD. Today after hour 17 I felt this wonderful euphoric feeling while resting in bed watching tv. It hit me out of nowhere, my head got light but not in a bad way, I was just feeling extremely loose and stressless, yet focused. My neck and back released all of its tension, I’m feeling no worries or tightness in my upper extremities. Never been a fan of carbohydrates all my life really, my father never allowed us to drink soda, juice, or eat ice cream, cakes, and breads, he was very strict with our diets, so I think my body easily fell into the ketosis and gave me these energetic feelings. For that, I thank the man. All of my cousins are pretty much over weight and sick, while my siblings and I are feeling great in our late 20’s and early 30’s. We’re never sick. Refined carbs and processed foods/sugars are torture for our sacred bodies. It’s crazy how we eat here in the US, it disgusts me. I can’t stand seeing my friends down 2-3 sodas a day, then slam their gut with pasta & desserts right before bed. It grosses me out. Keep up the great work Fung! Whole natural foods, it’s common sense.
I wouldn't say people in the 1960s were not exercising. I don't know what other parents did, but mine threw me out of the house at 9 am and told me to come home when the street lights went on. We ran all over the place. Playgrounds, climbing trees, riding bikes. My parents worked on their feet. Now tech has people at their desks, kids are not out from 9 am til dark stopping only for two meals. That's exercise. Now, we have to use gyms, we are sedentary in our work habits.
Thank you Dr. Fung....my A1C went from a 14 to a 6.4 as of last Friday. I started 16/8....then 20/4....now OMAD.
Wow! This is one, if not the best videos explaining obesity, hunger and hormones. Thank you.
Dr Fung changed my life and saved me from diabetes. Thank you!!!
Me, too!
How so? Please elaborate. Thanks in advance.

@@tohopes - finally an educated person.
socal20001 aye please how can I reach I have someone in my family that suffers from that
As a type 2 diabetic with an A1C of 6.5, I tried a high carb low fat vegan diet for 4 weeks. My A1C went up to 7.5 and my glucose readings were up to 20.5. And my hypertension up to the high 140’s over 88 on average. Proof that high healthy animal fat, and olive oil etc, and animal/keto low carb foods are the best. Fatty fish is excellent, beef, chicken, cheeses, eggs and low starch veggies are excellent.
Thank you Dr Fung!
You really have the courage to tell us the truth! Thank you and may you get to live up to 120 years of age!
He's wonderful. A real true Doctor. Who is trying to help patients not the drug comanies . I hope everyone hears his message.
Sure, that's why all Americans are so skinny...
@@sandracarli1110 whats your point?

If you want to live longer, then you have to take more from the Adventist Health Studies than the protective properties of a nut.
lowest BMI - vegans
lowest Diabetes - vegans
less Cancers - vegans
now guess how much saturated fat a vegan consumes and how many carbs?
Really glad to see you killing this dogma. The people who were responsible for our health have failed us.
This is one of your most interesting videos that synthesizes history and data to explain how our nutritional “experts” came up with the low calorie, low fat diets. Excellent investigation. I hope you get the recognition you deserve for your contribution toward righting this misinformation.
The FDA still has magic mushrooms and LSD listed as schedule 1 drugs which are supposed to have no medical benefits and be highly addictive. Both magic mushrooms and LSD are the OPPOSITE of addictive! If you do them enough times, you will have a bad trip and a strong desire to never do them again. The FDA has marijuana as a schedule 1 drug, once again not addictive, and yet the FDA cleared oxycontin, basically purified heroine, a highly addictive drug (and the cause of the opioid crisis).
Moral of the story. Don't trust government organizations for health advise. The politicians have their campaigns paid for by private corporations. They will cheat lie and steal in order to prop up these industries. All their advise is great for business for rich people, if its good for you than that is just incidental and a pleasant accident.
Doctors are not responsible for our health, we are
Thank you Dr. Fung, got fatty liver and migraines plus back pains. after i did what you have said, boom, done,gone...
Joshua Opleda how you get rid of your back pain? I’ve a back pain and it’s killing me
pleiades drew thanks I’ll check it out
actually my back is caused by inflammation of my body because of my fatty liver, i just removed sugar and carbs in my diet and took more on salmon, cod, seaweeds etc... but i do 23hr fasting alternately. in one week, its gone
@@Stoneface_ I lost most of my chronic pain and no more migraines by doing Keto, 18/6 intermittent fasting and adding electrolytes.
very good! how long for fat liver recovery? i have that too
Also, more snacking foods with carbs are invented every day causing food addictions.
Have you seen the generic cereal at Walmart? They are putting marshmallows in everything! FOOD SINS
I eat 80 percent carbs and I have a 6 pack. Marshmallows are not carbs. Oats and brown rice are carbs.
@@jaxonv2098 Marshmallows is just sugar and some other ingredients. Sugar is carbs. Thus marshmallows are carbs since they are made out of sugar.
Because of lack of knowledge the people perish. Thank you for sharing your knowledge. It has certainly improved my quality of life. May you receive a hundred fold in every area of your life, for what you are doing for us. God bless you.

Thank You Dr Fung!!! This is the kind of videos that needs to go viral. A lot of lives will be saved! There is so much that is misunderstood...I am having such a hard time speaking to my mom about this, because the old thinking of fat is bad is so embedded!
D S French fry fat is bad. Avocado fat is good. Hot dog fat is bad. Sesame seed fat is good
@@PInk77W1 agree...but as long as they hear fat...BAM they don't hear anything else...anyway I got my dad to look at the logic of the science and he is on board...and dropped more weight than me...my mom on the other on hand does not want to give up certain foods. My mom is having a harder time giving up the carbs.
Thanks for posting this lecture Jason. I enjoyed it . I work in Sweden as a dr in family medicine . While we dont have the same epidemic as the US it is still a big issue and I think we could benefit from a revised approach in how we treat and what we recommend to our patients. We have challenges ahead. Hopefully we will find a way.
I finally understand the saying "I have a second stomach for dessert". Love your talks.
Great work!! I love it when he makes that little laugh after saying something silly like a calorie is a calorie..
Thanks Dr. FUNG! I started intermittent fasting and stopped drinking alcohol and have went from 227 lbs down to 204 in about two months, and still heading down. I really appreciate the education you provide so very much
Did you join up? www.dietdoctor.com/free-weight-loss-resources-from-idm
I joined a gym, worked out daily for a month (including high calorie burning Spin classes) and used a calorie tracker... Didn't lose an ounce. I found Dr Fung and Dr Berg on UA-cam, tried no sugar and low carb with IF. I've lost 3 pounds in a week. If this keeps up, I will evangelize for this man.
Pardon me, what do you mean "tried no sugar"
You eat
- no fruits (bananas, sugarcane, melons,...)
Or
- no industrial added sugars. In cakes, candy, cookies, sodas, brown/white sugar...
@@c-4839 no sugar at all... including fruit. However, I've now started introducing fruit every couple days as a dessert. But, I'm still staying away from added sugars and sweeteners. I've gotten a little more relaxed with all of it now that I'm a few weeks in, since I've gotten into the rhythm of intermittent fasting. IF is doing a lot of the work.
@@loganpeck5084 don’t do that. You are feeding addiction. Stay in keto and in about a month that sweet tooth will disappear. I lost 20 pounds in a month from keto / fasting. And I’m pretty terrible at fasting lol.
@@billybobbobson3797 thanks. I'm now down 12 pounds in 6 weeks. It's gone really well. I'm planning to keep up IF perpetually.
But Dr Fung's book goes into studies about the benefits of fiber. So I do consume some carbs if they're natural and whole. It's the refined flour and sugar that I find addictive and really unhealthy.
But now that I understand insulin response, it really helps me know what to eat and how much and when.
@@loganpeck5084 yeah you gotta eat fiber. Just gotta come from good veggies and not processed garbage
Thank you sharing your knowledge on fasting. Some people I have shared info with think it is dangerous to fast, but it has totally changed my life. Longer fasts, would be a little scary if I hadn’t listened to you first. Life changer for me!
Thank you Dr. Fung for your fine work. Your books and advice have helped me to have incredible numbers on my tests, to the point that my doctor is baffled that at 70 years of age I have such low blood pressure, blood sugar, cholesterol and all of my blood numbers and urine numbers are fantastically normal. He doesn't even ask me why or what I do. Oh, well. Thanks again!
Me too, at 67. My doctor is baffled but tells me to keep on with “whatever you’re doing”. And I know so many people my age that are having surgery after surgery and taking a handful of drugs every day and failing. Me? My health depends largely on butter, cheese, eggs, fat streaked steaks. . . a feast OMAD.
Why hasn't the American Heart Assn been sued like the companies in the Tobacco industry? States have had to pay a lot of medical costs over the years because of their poor advice...
Probably for 10 or so legal reasons. Like they weren't probably intending harm while the tobacco companies clearly were.
How dare you sue the AHA when they rake in billions from people? How dare you try to take down their cash cow?
AHA's links major to industry, indeed that's where it got it's original funding. Interestingly if you try to research this Google offers a lot of links tgat specifically DONT answer the question
The AHA is funded by all the major food industries, starting with Proctor and Gamble creators of Crisco oil and a prime promoter of nutritional confusion! They don't mind if you push keto or low fat, its all money in there pockets, but Dr Fung is dangerous because he encourages fasting and hormonal control and this cuts into profits of big food!
The American Diabetes Association is worse.
Followed diet based on Dr Fung's advice. Lost 15kg (33 pounds) in a few months but while doing less exercise than before. Feeling awesome! Thanks Dr Fung! My girlfriend likes my abs 😉
Thank you Dr Fung for improving my understandings and my life
I love Jason Fung. This guy is the absolute best. Very informative and to the point.
Thumbs up BEFORE watching because its Dr. Fung! I appreciate any material you produce. I find it well researched and thoughtful. I am a TOTAL supporter. Thank you for posting new content. :D
ThatOldBiddy Beware. Agreeing before the material is presented is the definition of conformation bias.
The data must stand on their own. Science isn’t about faith or belief, but facts - as long as the facts are verifiable and reproducible. That how science works.
Even though the low-carb diet eliminated my pre-diabetes, I have to acknowledge my experience is anecdotal. More studies are need to change peoples’ minds.
@@lohphat it's also hard to find anyone who's completely unbiased, especially on UA-cam. The presenters often have a stake in what they are presenting.
@@lohphat I don't think that more studies are needed to change people's minds, but it has to reach wider audiences
It's not anecdotal if there is proof that low-carb diet helps, and there is proof
But you are absolutely right about biases, it's pretty dumb to let yourself borderline worship someone and not question anything they do.
@@lohphat I agree with you to a point, but for 50 or 60 years nutritional science has been anything but real science and the studies that are scientific are being buried, but Dr Fung is fully exposing the real science and anyone that has listened to him knows ahead of time that he is spot on!
Thumbs up before watching!
Dr Fung, this is fascinating.
When I eat zero carb then eat a food that has high fructose corn syrup then I get hungry. No matter what I eat, I don't feel full. It is crazy. I now stay away from HFCS.
Yeah if I eat a bunless cheeseburger with half a tsp of ketchup I know I'm gonna pay for it the next day. Sometimes I fast after that.
That what he's trying to tell us
Alan The Cat .
Also check out sauces for salad, and processed sliced bread. They put sugar there too. There is a lot of food that don’t taste sweet that has added sugar. That’s food industry’s way to keep us hungry, buying and eating more crap.
High Fructose Corn Syrup is a carbohydrate... all sugars are carbohydrates.
xandercorp he said “when I eat zero carb *then* eat a food that has high fructose corn syrup...”, so he means after eating zero carbohydrates. He never suggested that high fructose corn syrup wasn’t a carbohydrate.
HUGE FAN, I just have to thank you for your books and videos, they are changing my life :)
this lecture is pure gold!!! thank u soooo muuuuuch jason fung!!🙏. listening to this all the way from ......mexico
What a presentation. How often do you learn this much important stuff in less than an hour?
I went for my HBA1c Test last week. came out at 4.8. No medication involved. I just started using LCHF and intermittent fasting last January.
Can you give me an example of your food, please
That's amazing, congratulations to you! :)
But what was your HBA1c before doing LCHF and IF?
@@tohopes - For what it's worth here goes my 2 cents. Very similar situation as described by the OP.
January/February 2020 my HBA1c was at 8.9 and still going up. Adding to that, tremendous weight gain, my pants went 3 numbers UP! High blood pressure, cholesterol, inflammations and pains all over my body. Pretty awful scenario. :-(
Until I learned about LCHF and IF! (Thanks Dr. Fung)
THIS WEEK (August 2020) I could wear my old pants again for the first time since this odyssey started!!! Type 2 diabetes reversed, blood pressure OK, cholesterol OK, no more inflammations, weight is going down, etc.! My Dr. was astonished and I was marveled! The combination of LCHF and IF can save lives and improve life quality.
For goodness sake anyone in similar condition. PLEASE consider trying it. Its a life changing option...practical and cheap also!
@@crpth1 that's great. how much do you fast?
My favorite health warrior! !!! Rock on health warrior!
Dr Fung you you are the best. Thank YOU!
I love Dr. Fung as he explains intermittent fasting. My wife has struggled with her weight for thirty years and at 308 lbs she gave in and had a gastric sleeve performed two and a half years ago. Over the next year she lost 90 lbs. The down side was she had yards of loose skin. That didn't last long as she gained 30 lbs back over next the year. Her favorite go-to snack was chips and bread.
My story is a bit different. Six years ago I was diagnosed with stage four neuroendocrin pancreatic cancer. I went to three different doctors who all gave me around two years to live. I had surgery to remove a seven inch tumor and half my pancreas, spleen, 12" of upper colon, two scoops of liver and a dozen lymph nodes. Four months later they found ten new tumors in my liver. New and improved expiration date-one year...I had two rounds of y90 glass beads which killed nine out of the ten tumors. One year later I had surgery to remove 35% of my liver to get that one die-hard tumor. One year later, they found a four inch tumor on my sigmoid colon, a one inch on a kidney, two on the pelvic wall and one in my appendix. My oncologist suggested palliative care and end of life transition. I didn't give up, I had another huge surgery to remove all those tumors. Fast forward another year and another surgery to remove two tumors in lymph nodes and another scoop out of the liver. I'm running out of spare parts! Last August the scan found four new, widely scattered tumors. My blood work showed some disturbing results, A1C 6.3, total cholesterol 255, LDL 158, triglycerides 175. I went on line and watched about a thousand videos on diet and life style. December 1 2018, we changed our diet and everything changed dramatically.
In only thirty days I lost twenty pounds, my blood work changed completely. Cholesterol down to 155, LDL down to 78, tris. down to 123. Then Feb. 1, we started intermittent fasting with a four hour eating window. My wife has lost 30 lbs but the biggest change is all that loose skin has improved drastically. I"ve now lost 44 lbs in six months and feel better than I have in 20 years. I had ED and shortness of breath when I exercised, both have resolved.My wife says she has so much energy and is never hungry until a hour or two before breaking her fast.
But wait a minute, we changed to a high carb, low fat-no oil vegan diet. The only diet ever proved to reverse clogged arteries. The keto diet has never done that. It was so easy to give up all the ice cream, cheese, and animal products. After a month or so, you don't miss any of it and you wonder what was so great about all that fat. Dr Fung has explained intermittent fasting to a T and the roll of the liver and glycogen and fat burning, but I feel he is missing some info on fat in our diet. He also never mentions the Loma Linda health studies or the diet of all the blue zones except the Mediterranean diet.. There are no antioxidants in animal products, they are only found in plants.
For the first time in six years, my last scan found no new tumors and no growth in the existing tumors! New and improved expiration date? Who knows... I betting it's more than a couple years. For the first time, I don't dread the next scan. I'm expecting more good news.
He goes into depth on many other diets so that's a lie. Two you do what's best for you. He is doing his best to give more accurate information to the public and you're sounding a bit ungrateful. Your specific diet won't work for everyone. Just cus that's what you needed doesn't mean it's universal. You older ppl always tend to think you know it all and it's your way or the highway. Like sorry your perspective is not the end all be all.
You're spot on and I agree totally with you Doc. There is also one other issue in the US starting in about 1915 which was the addition of chlorine to the drinking water supply. From what I understand this accelerated the effects of a poor diet. I don't know if you've ever looked at or considered this but as a chemist myself wanted to note this. Please keep up the brilliant work Doctor.
So infomative... Being a Dr. I understood each and every phenomena involved in the accurence of obesity.
May God bless you
Doing great on Banting lifestyle and Intermittent Fasting. Thanks Dr Jason Fung.
@a Supernova It was hard initially and I cheated a lot. Now, I just don't think about it at all. I am ok with squash and sweet potatoes as substitutes. All the best.

saw the notification and couldn’t help myself! love learning from the doctor and makes work so much more fun! :)
We get fat because the foods sold in our supermarkets is garbage for the most part. food sellers don't care about healthy foods like other countries why places like fast food restaurants make big money they are aware that they can pull in people by making junk food taste good. Not to mention the way Americans lives are so fast paced there's no time to really stay home and cook a real meal. Sad situation indeed . Slow down and listen for birds singing and watch the seasons change, we have forgotten how to enjoy being alive try to get in touch with ourselves again. Take notice of the foods we are putting in our mouths, if it taste good take a minute to find out why.
Thank you, Dr. Fung, for your sound advice. In 13 months, I’ve lost 95 pounds and have about 30 more to go till I reach my goal. I wish I’d known all of this information long ago, instead of spending years struggling with my weight. I’m now in my late 40s, weigh less than I did in high school, and have levels of energy that rival those of an average teenager.
What an achievement. Well done. I need to lose over 130 lbs, so it's so helpful to hear these testimonials.
Woot! congratulations.
Dr. Fung is brilliant. I could listen to him all day!
Yes, the French consume saturated fat, but the French consume small portions of all they eat whereas in most countries people are serving too much saturated, high carbs - pizza, sodas, etc., served in massive amounts. Also a lot of fried foods, against in huge amounts. The French eat in moderation.
Thank you, Dr. Jason Fung. This was a great lecture, very informative one of the best.
Thank for you pioneering the obvious (hello, type 1s) yet apparently revolutionary / rebellious idea that Insulin is the real player in weight management. I got bullied to absurd length for making a point of it with CICO supportes, and with even Keto supporters when I dared to point out that even protein elicits an insulin response (albeit not as high as carbs of course). I guess I was also naive thinking a girl could dare put together research, making it sound accessible to the layman, and still be respected, but hey, I'm glad I always have your books and article to link to when people feel like I just am pulling stuff out of thin air. Thanks for all your amazing work!
You mean people get fat soley on their insulin levels and not what they eat?
32:13 I had to check if it was true that my country Denmark had banned transfats in food. I had no idea, but yup. Companies are only allowed to add maximum 2% in their products. Adding more can result in up to 2 years in prison.
Probably the clearest and most concise explanation available - even the most cynical would find this hard to refute. Sadly though, they will and because of this, people will continue to die too soon and our health services will continue to crumble under the weight of the financial burden the current misinformation causes.
The word genius has become debased by overuse. But Dr. Fung is a genius, full stop.
Fantastic summary of data proving the "CICO" theory of eating and weight reduction/health improvement correlation does not work. Thank you, Jason!
definitely doesn't work on a highly refined carb diet where your insulin levels are kept elevated.
WOW that was excellent. Ive heard Dr Fung say all this before but its always good to get a topup.😁👍
You are doing God’s work my friend. Thank you.
Dr. Fung keep doing what you are doing because you are saving lives! Even tho i am not diabetic i got to realize carbs and refined sugars were the reason why i got to 130lbs which is hard for me to moved. Then i did my fasting lost 5lbs however i went back to carbs coz i didnt know it will turn into sugar in my body so i gained another 2lbs. Sigh. Then God is good i ended up watching Dennis pollock then i research your name and i was convinced to do the low carb diet about 7 days ago! lost 5lbs. 2 days was excessive water weight comingout after that i started losing my belly weight which i hated the most since i started having ice cream and lots of fried chickens lol. So Now black feces are coming out of my body! Looks like sugars! coz sugar turns into dark like molasses when u heat that up. Now im so happy and thank you for all your good works! You are God sent indeed! 5 more lbs to go!!! my ideal weight is 115lbs since i’m 5’4 only! 😁
No words to thank 🙏💕you. To control my obesity and type2 diabetes. It needs guts and courage to oppose what we study in medical books
Thank you for your work Dr. Fung.Please continue making content!
Dr. Jason Fung is my fasting/keto Guru. This is my story; five cardiac events over 18 years, two MI's, a triple bypass, four angioplasties, months in hospital, nine drugs a day, fat liver disease, Type II for the past five years. I could barely walk up the stairs in my house without angina. My wife found Keto for me in August 2018, I've lost 68 lbs and today I regularly walk 10 km per day, ride my bike for an hour, strength train for 30 minutes and am refinishing a canoe to go canoe camping this summer. Today I only take a baby aspirin as a prescribed drug. Keto changed my life and it's easy to do if you are committed to getting healthy. Change your life, keto works, my blood sugar level went from a high of 16.5 to 4.7 in three months and my BP is now stable at 118/68. Have fun and Keto On.
Sharing, and hoping others share... This information will change people's lives. Incredible....
We could change the world with this stuff!🤠
Dr Fung is the voice of researched reason. So grateful for your generosity in sharing 💙💚💛💖❤
Down 137 lbs in just over 11 months thanks to your truth regarding carbohydrates, fats, insulin and fasting. It is not just diet for me I also fast 36-48 hours at least once a week the other days I fast 20-24 hours.
Congrats. That's wonderful! That's my goal! Now going to try longer than 18:6 daily fasts. Did you drink broth?
Way to go, O.M.A.D. for life plus all that, congratulations!
@@reginapontes5672 I did at the beginning. And I still do with longer fasts. I have lost 60 lbs and I am at my goal weight now. Pre-diabetic. Blood Glucose down from 100s to 70s in 6 mths
Wow! wonderful accomplishment, congratz.
This presentation is an amazingly well done explanation of a bewildering phenomenon I've been unable to understand forever it seems! I began seeing the obesity levels rise like the tide in The Bay of Fundy when I was in HS. I wrote an essay about it in English class I called "Fat Chance" and I've felt like I was near an explanation I'd find satisfying, but this has me close to really Getting It!
Thank you very much Dr Jason Fung, keep up the good work and you're a saviour
One presentation that is WELL WORTH being shared by all who watch and learn from it..... brilliant!
Dr. Fung thanks for sharing this information, I have insulin resistance and I didn't Know it until I watched the information you are sharing, thank you so much, you have changed my life.
Doing keto is largely returning to the diet my mother taught us in the 1950s. Breakfast (cooked, eggs for children, lamb loin chops for adults) at 8, lunch (tomato/ham & cheese sandwich) at 1, dinner (meat & three veg) at 6. No eating outside of meals, no sweets, cakes or biscuits (cookies). Ice cream/cake on birthdays only. Limits on “starchy” foods always, because starch (bread, potatoes) made you fat, every woman knew this. Pasta & pizza were unknown, rice was rare. Fat meat is good for you, don’t forget to suck the marrow out of the bones! Liver & kidneys were particularly good for you but good luck getting the kids to eat them! Very young children had to be bribed to eat their vegetables with the promise of a tiny square of homemade raspberry tart with a spoonful of hot custard afterward.
Elite food
Make sure to cook the vegetables to be very tasty so children will want to eat it.
I just wish you'd post more often.
Love dr fungi he is awesome so kind of him to share and help so many people.
Portia Emery yeah...he sounds like a fun guy 😜
Congratulations! Wow... you are doing great! You are encouraging me. I love to watch you, and I am very happy to hear that you will keep doing videos even after you reach goal weight. I lost 123 lbs, but sadly I gained it all back which makes me very depressed so I haven't left the house in four years. So I want to learn from you how to keep it off. (I am very very short, so that is a lot of weight on me.) God bless you my friend!
scottishcovenanters Try IF=intermitten fasting
Fast 1 or 2 day then eat one day. I think he has a video on it as well.
Don’t give up, persistence is the Golden key.
Give us more, Doc Fung can we please get at least one video a week👍🏾
I believe he has patients to see and a practice to run ...
WOW !!! This is an absolutely amazing presentation. Dr. Fung this is the BEST explanation ever. Thank You !!! ✨
This video is "long" but really worth watching. Every chapter has excellent info that is easy to consume and helps understand why things like Keto exist and why fat is good for weight loss.
When pizza chains went nationally, this WAS the beginning of the end. When fast food turned into a 5th food group. You can eat it, breakfast, lunch and dinner. Everyday!! The industry spends billions of dollars annually in advertising. Not too long ago, fast food was a treat. Something you would have on the weekend to give mom a break from cooking dinner. A few generation's have been brainwashed into thinking it's a the norm. AND fast food is cheap, habit forming and it taste good. Jumping off my soapbox NOW.
Excellent talk Dr Fung. As a physicist I've always been persuaded by the thermodynamic considerations. After all, if you need X calories simply to lie in your bed all day and do nothing, then if you eat X - 500 calories per day you will lose weight because that energy has to come from somewhere. You have to 'eat' yourself in order to survive. It is a compelling argument, but as you beautifully explain here, it's far too crude a model and, whilst correct at a kind of gross overarching level, it does not capture the full interplay and dynamic of what's really going on. The problem with calorie counting is not that it "doesn't work"; the laws of physics and thermodynamics are still valid. It's just that X, our basic energy requirement, is a function of time and it adjusts so that when we start a diet we might be in calorie deficit, but at the end of the diet still eating the same stuff we might be in calorie surplus because X has decreased to compensate for the regular deficit.
I'm pretty sure that the food our ancient ancestors ate didn't come with any nutrition labels. They didn't need to count calories, and I'm also pretty sure they weren't obese. I mean the idea of a tribe of hunters waddling after their prey seems kind of ridiculous. So something has clearly gone wrong over the years and we've lost some of our ability to self-regulate. This is possibly due to the abundance of food today but also possibly because we're simply eating the wrong kind of foods. The hormonal regulatory mechanisms are all out of kilter with the current professional notion of a healthy diet based on the food pyramid. And this is something you explain beautifully here.
Dr. Gary Fettke had a good reason we crave these sweet high carb foods. He said that because in nature, sweet fruit and sweet veggies are a fall bounty; that was when we would find them and we would eat as much as we could, because we needed to put on fat for the coming Winter months when food would be scarce. He has a wonderful Video about it,....just Goggle Dr. Gary Fettke, you will enjoy his video too. He's funny!
The metabolism slows down when we eat less.
Everyone needs to see this video
Dr.Jason Fung is a medical genius.God bess you for all your ad ice and good work you have done as well as all the informative videos.This particular video is a MUST see for everyone.
I have to say that I've learned this. I debunked a biochemist using this knowledge largly. Thank you Dr Fung for all that you have done. Keep up the amazing work. We look up to you. 😀
so cigarettes caused heart disease. To avoid blaming them, we blamed fat and switch to sugar, which created obesity (and diabetes) and even cancer.
Thank you for coming out with this video. Great information! I’ve lost 50 lbs. since June 2018 with Intermittent Fasting and one meal a day with Keto lifestyle. You provide the truth regarding obesity!
What was your diet like before watching this guy? 4 meals a day? 5?12?
I cut out sugars (as much as possible), I eat (healthier foods, as little processed foods as possible) between 8 am and 4 pm (biggest meal around lunchtime) and I started exercising more. Lost 35 kg since july 7th 2020. Went from a 32.8 BMI then, to a 21 BMI now. Feeling better than ever. Cutting sugar was the best thing that happened to me btw.... I have way more energy now.
Jason, you have no idea how much I appreciate your work. (If only gratitude could be delivered in dollars, you'd be a very wealthy man!)
You deserve a Nobel Prize for medicine! 😍😍😍
He makes so much sense!!
Thanks for sharing your research on the roots of the obesity epidemic.
In the 70’s even doctors smoked in his/ her office . Now this is not acceptable.
Gratitude I hate that employers have the power to control what I do in my free time.
Dr use to say pregnant women should smoke.
1962. $$$$
Thanks Dr.I read all your books in French. I reversed my T2B and feel great.
Genius!!! Pure and simple! Great work!
Excellent, as always 👍
