What is particularly noble about Dr. Fung is that this information is put on UA-cam for anyone to find and use and benefit from. Its not behind a paywall, its not a commercial for buy my product, its just out there for anyone to use and get healthy. If only I had this information 10 years ago. I only recently discovered Dr. Fung in June of '22, but have lost over 70 pounds since then. Having watched almost all of the videos by now, I can't help but grin a tiny bit when Dr. Fung sounds a little exasperated at trying to say nicely for the 1 millionth time, "your eating to darn much!". I guess this is pretty much what ever doctor goes through with their patients. 😀
@Kent You asked how I lost the weight, I fasted and walked an hour or so everyday. I eat my last meal Sunday night, and then fast until Friday morning. I stay hydrated with water or tea, and take salt + an electrolyte supplement everyday. I tried various combinations of alternate daily fasts, but I was hungry all the time. Sunday to Friday just turned out to be the easiest, least complicated way to do the fast. In the beginning I was losing about 5ish lbs a week, but after about 6 months I'm only losing 2ish lbs a week. Though I have no way to measure, I don't feel like I've lost much if any muscle. The first week wasn't much fun adjusting to fasting, but 6 months later, its easy peasy.
@@real_chaorders Honestly, its easy peasy. From a physical point of view, I'm not hungry, I have tons of energy and truly, Monday through Thursday I feel great. Physically I feel like I could go a week or more without food. Its the mental challenge is what's so difficult to overcome. By Thursday night my brain just won't let up thinking about food. And trying to get any sleep Thursday night is just a exercise in futility, I toss and turn all night. I'm guessing its because of the counter regulatory hormones. Once I start eating again on Friday I feel awful. Its like how you feel after eating that huge thanksgiving meal, except I feel that way all day Friday. But at least I sleep great Friday night. Sat and Sun I do ok, I just feel normal again, then Monday and Tuesday I don't even want to look at food. 😎
Maybe you could buy his book "The Obesity Code" to reward Dr Fung. And, this is not the case of Fung, but don't think that many doctors have feelings for their patients. You're just like a broken car which you bring or repair at the repair shop. Actually you give them work. Think about how much money Eli Lilly is making with insulin. The price has skyrocketed through the years !
I’m on day three of starting 16/8. I went to visit a friend and they offered me two of the things I love most. BBQ potato chips and peanut butter cookies. I wasn’t hungry and I managed to not eat any of it. It was tough. But I kept telling myself I wasn’t hungry and succeeded in not eating any of it. 🎉

Calorie restriction leads to a decrease in metabolic rate, limiting body fat loss. 16:38: 🍽 As energy drops and metabolic rate decreases, hunger levels increase due to higher levels of ghrelin hormone. 22:08: 🔥 Fasting increases noradrenaline levels and switches the body's fuel source from food to stored body fat, leading to increased energy expenditure. 27:22: 🍽 Skipping dinner allows your body to use stored fat for energy and reduces hunger levels. 32:24: 🔑 Controlling hunger is more important than controlling diet for weight management. 38:01: 💡 Fasting is a natural and beneficial part of our physiology that can be done by both males and females without any harm. 43:22: 🍽 Fasting is more important now than ever due to the prevalence of obesity, type 2 diabetes, and metabolic disease. 48:51: 🕒 The physical hunger during fasting tends to decrease, but the psychological hunger from constant temptation is the real challenge. 53:54: 🍽 Stimulating your appetite with sweet foods can lead to overeating and weight gain. 58:56: !

Recap by Tammy AI
Congratulations on your weight loss and improved health. Which book of Dr. Fung's did you read? I recommend his The Diabetes Codd even for non-diabetics.
Dr Fung just keeps honing this message - still getting better every time he does it ! Also, the person interrupting the audio is clearly not following the presentation (and requests for muting) , so next time, just kick them off.
So great to spend a Sunday afternoon settling in and watching a Dr. Fung lecture! (Better than the Packers today 🤪😅!). I remember when I started watching almost two years ago I was wondering if all this was really true and worked but felt it was worth a try. Now, I watch and think "Yes! That's so true! That's exactly what happens and how it works!". I'm 59 and I've lost over 150 lbs. and have been maintaining it well since then. The transformation has been profound. I did it all on my own, just by following and reading Dr Fung's books. I'm off my blood pressure meds, my osteoarthritis pain is so much better and my asthma is gone. I'm so thankful. Learning to fast changed my life. Thanks again for all you do 😊🙏
I'm eternally grateful for this knowledge. This is the 1st time in my life that I've felt in control of what I eat and weight loss. Haven't binge eaten since Intermittent fasting and cutting refined carbs and sugar. I could almost cry of happiness.
In 2018, I did not know what to do anymore to lose weight. I was browsing again to find a new option and - THANK GOD! - I found Dr Fung´s book "Obesity Code". Since then, I started fasting and my health is much more strong today. I´m sure, one day, all the world will accept the truth of what Dr Fung is saying. Thank you, Dr Fung for sharing your knowledge and keep fighting for the Truth. You are saving lives. God bless you!
i cant thank u more . i was 75 kg when i thought of getting in shape aroung 68kg .i tried all things in between but always my weight kept on increasing . same when i saw my weight 83 kg , i thought lets do it now or i will surely face health problems . but again it went to 92kg . then i found u and watching your videos again and again helped me to understand root cause . now after 4 months , i have lost around 15kg , still doing .. but loosing weight was not so much easy and fun before u sir . thank u for changing my life forever . i cant describe in words what your videos helped me .. thnq u sir much love
80 days ago, I was one reading all of the comments on several of Dr Fungs videos thinking; there is no way this many people have been healed from not eating. 70 days after starting IF, I’m 60 lbs down, BP in check, A1C in check, foot fungus gone, skin issues gone, my addiction to food I didn’t know I had is cured. I’m feeling so much better about myself and can’t wait until I loose the remaining 40 pounds to get to my goal of 210 Thanks so much Dr Fung. I owe my life to you
@@trishkline6507 If you start out severely overweight, 60lbs in 2-3 months is entirely plausible. I lost 20lbs in my first 3 weeks of fasting a few years ago.
@@t1mmytiger yes. I have a smart scale and if there was a way to post a screen shot of it, I would. Like I said in my post, I was reading the comments and thinking there was no way. I also was 310 pounds and high body fat %. My body was in so much stress, I could barely walk up 2 stairs without getting winded. Best of luck to you and your journey!
I've added this to my Dr Fung Lecture Playlist. I use it to refresh my understanding (I have your books plus the Audible recordings). It's great when I traveling and send to friends to share what I've done to reverse and reclaim my health and debunk their view of Type 2 being a progressive chronic disease and their "essential" Hypertension. Thank you
I have a similar playlist and added this Dr. Fung interview that I stumbled on this morning. It's comprehensive and just as in this video Dr. Fung is quite relaxed. ua-cam.com/video/36oVGVokcNQ/v-deo.html
@@finosuilleabhain7781 I was hoping the OP would answer this for themselves, but since they haven't I'll just mention that "essential hypertension" (primary hypertension) is basically hypertension that can't be linked to a specific cause like injury etc. Physicians often link it to genetics and sometimes just say it is inevitable with age. If you google the term, you can learn about it in more detail.
@@AzaleaBee Thanks, Azalea. I'd have done so straight away had I thought it might be a term, but was thrown off that scent by the combination of 'their' and the quotes around 'Hypertension', which led me to wonder quite what the OP's friends might have been saying about the subject. It's called overthinking, I believe. Thanks again - most helpful of you to have stepped in.
Really good information, I've been running 16/8 IF for 3 weeks , dropped 11 lbs, feel very good, going to plan on it just being what I do going forward.
Thank you, such a great explanation, I just did a 48 hr fast over my weekend. I sometimes feel a bit tired during my fasts, but when I stop and re feed I’m bursting with energy. Love fasting ❤
Sounds almost like you do not like it. "I feel better when I eat? Just go through 2 days of pain while I work". You may want to look into your diet when feeding. On average you energy levels should be increasing. Sounds like diet is poor or you eat in excess during your feeds. Should be able to find info on that.
Thankyou so much Dr.!! You have changed my life! After 3 months I have lost 30 lbs and I'm no longer pre-diabetic, my thyroid is back in normal range, my joints don't hurt and my plantar fasciitis went away!! I read the Obesity Code and have followed your videos and learned so much and it all makes perfect sense. I'm currently doing OMAD (one meal a day) one big meal, and try to eat healthy but still eat whatever I want. I've learned to keep my sugar and carbs low and it totally made a difference. I can't thank you enough!
Absolutely stunning. The information you give out for free is live saving, but unfortunately not shared by any „normal“ physicians. But that’s okay. We know better.
I think it’s beginning to be shared by other physicians. My doctor read me the riot act over my diagnosis of non-alcoholic fatty liver. She referred me to Dr. Fung’s videos. My husband and I have now lost 12 and 10 lbs respectively in two weeks.
Hello Dr. Fung, Thank you very much for promoting a healthy lifestyle and fasting to cure Type II diabetes. I am a big fan. I just did a 24-hour fast yesterday and lost 2 pounds. I was slim until I gave birth to two children and hit my mid-40s. I have been struggling with weight loss/weight gain cycles. Now I finally find a way to lose weight and keep slim.
Perfect example of a way to breakdown a complex subject but make it sound obvious and simple. I have tried every diet under the sun in the past 10 years and IF is the only thing that just works and is easy. Now thanks to amazing lectures like this I understand the science properly and can openly discuss with evidence with anyone. The only terribly sad thing is that you can't really commercialise fasting like you can juice fasting or gyms etc etc so there is so much vested interest in not publicising IF.
I love Dr Fung's message each and every time I listen to him ! it's always relevant. It's always new to my ears. I love all of his messages and think that one day the entire world will wake up and take this on board too. Thank you so much Dr Fung 🙂
Thank you for all your diabetes informational videos explaining the necessary dietary components of preventing & reversing excess blood sugars causing insulin resistance Diabetes 2 metabolic syndrome. It’s just so very hard to UN-learn a lifetime of incorrect eating. Thank you again.
Wow...I'm 51 and the "eat less, move more" idea has ruled my life for 30 years. I just sucked up the fact that I was hungry all the time and it "worked," until I regained and did it again, just as you said. I found out about intermittent fasting 3 weeks ago and have done OMAD 75% and 18:6 the other 25% of that time, and I've lost 6 lbs! And I'm totally satisfied, hardly any hunger and my one meal is literally all I can eat at once. I feel great and see that my goal is not only in view but I'll never regain, again!!!! I might have to increase to two meals a day; I can't keep losing 2 lbs a week for much longer...what a problem, LOL! Thank you for laying it out so clearly!
Thank you very much, Dr. Fung, you're the first true Dr. in the world. No other doctors have ever healed so many patients like you. You have treated millions of people over UA-cam exceedingly. Your videos will continue to do so for the rest of time. God bless you to live longer. You are a copy of Jesus
I had it done in 2001, if I had found IF I NEVER NEVER would have done that to myself but I was so desperate!!! I did lose 130 pounds but with IF I have lost 70 pounds in 7 months😊
I’ve been listening to you and others’ Keto and fasting videos since October 2021. I started intermittent fasting in March 2022 and on and off extended fasting in August 2020. I agree 100% about hunger pains (waves) passing during short and extended fasting but you are the first to explain why very simply. To paraphrase your explanation, when not fasting, you get hungry, you eat, the hunger goes away. When fasting, you get hungry on and off during your fast and your body starts eating your stored fat and the hunger goes away. Two questions 1. Will fasting help fight Diabetes Type 1? 1. Will a 72 hour or longer fast, resetting your immune system, help fight the HIV/AIDS virus? Thank you for all your videos
You are one of my heroes, Dr Jason! I have been trying to help someone( in her 50’s) who wants to lose weight and is trying to use the Dr Adkins book. She is TYPE 1 DIABETIC. she gets scared if she tries to skip breakfast, and I never hear you talk about type 1 diabetics and fasting. She is overweight but not obese.
I began 16/8 intermittent fasting, 2mad, carnivore diet except include string beans, eggplant, broccoli, cauliflower, and cabbage in my diet. I increased exercise daily but not much. I eat until I am full and after 2 wks I feel better. At 75 I want to reverse type 2 diabetes, bring 6.9 a1c down and lose weight. I am 220 lbs and want to lose 30lbs. Thanks to your advice I find it stable regardless what restrictions others offer online. I have a dr appt in 6 wks and hope this will show improvement of my 5’8” female person.
Thank you for giving me my youth back DR Fung ! I lost 100 lbs in 4 months. 36 hour fast then intermittent fasting while eating very low cal diet. Rode my bike a couple times a week about 45 min each time and paddled my kayak for fun on Saturday and Sunday. I was never starving !!!!! I’m 62 and 209 lbs. Iv kept it off over a year now. Thank you sir !!! Ps. Never drank water, two to 3 Liters of Diet Coke a day. Been doing this for over 34 years !!!
Thank you sir for posting this!!!!! I have been begging for help through diet and exercise for a very long time. All the Drs want to do in give me a pill or have me follow the diet that you mentioned is "surface knowledge". I have NAFL and a calcium deposite in my aorta. I refuse to take a statin, because I want to lose weight and correct these issues using a more natural process. I have now put your site in my Favs. I wish you had a practice here in my hometown of Greensboro, NC! But I am so glad to finally find someone with sensible information. Thank you !Thank You! Thank you!
Fffffuuuuuunnnnnnnggggggg! Thanks for answering so many questions I had and explaining so many factors involved in IF. With such a clear and concise presentation as well.
I have tried fasting for a year.. and I love it… I just lose discipline and go back to overdosing on carbs every other month… currently attempting a 7 day fast (water) hoping it will help me to be more disciplined with OMAD. I’m 60 hours in out of 178 but feel good about this and Dr Fung was the first I ever heard about Fasting… Thank you Doc
thank you 🙏 you save my life i was diabetic and 204 pounds when see your first video i say maybe i can make it and i bay your book i started festing and keto 2 years a go now i’m free diabetic and 145 pounds very healthy i still doing i change my lifestyle and my husband we doing to gather i’m eating only one times they never getting hungry.thank you 🙏
Excellent review. I'm more than 4 1/2 years into a super low carb and intermittent fasting way of life. I've lost 105 pounds and at 65 feel like I have a new lease on life. Thank you for all you do!!!
@@ouidabordji6438 Absolutely not! If you're adapted to burning fat instead of glucose for fuel, your body happily does so. If you eat all the carbs, then you never adapt to be a fat burner, your body stays a glucose burner, constantly burning those carbs demanding more and more, and your metabolism slows because on your "eat less, move more" way of eating your body fears famine and starvation. I've yo yo dieted from age 15 to 61 and that way never works (for me at least no more than 6-9 months) . Cutting carbs way down (for me almost always under 20 whole carbohydrates a day) and intermittent fasting are the only things that work. My intermittent fasting is 1-2 meals a day with at least 16 hours between supper of the eaving to lunch the next day. No long term fasting for me as I'm on blood thinners permanently and 24 hours is my limit without food or it seriously messes with my dosages. If I can do this after 55 years of fighting fat ( most years morbid obesity) anybody can!!!
Dr Fung is a genius that has not fallen to the FDA and is not not not afraid to tell us what is happening in our bodies. I have a Masters in Hormones now. And I thank you!!$
Thank you for posting a nice summative refresher video. I started watching Dr. Fung about two years ago and I think I've watched every video and I've read almost all his books - you're an absolute life changer. I lost 50lbs and it has not come back even with going on holiday for a month (went to visit family after four and half years) and now fasting is just my normal eating patterns. Thank you Dr. Fung, you are literally a life saver for so many!! I would like to know how to share this with friends who often ask but when I tell them I fast they almost immediately get defensive and say "oh I could never do that" or "I have to have eat (generally carbs) or my blood sugar drops and then I'm weak" etc. I haven't figured out how to respond to this in a positive way so I just let it go. I've tried explaining the science behind it but it falls on deaf ears, my guess is because they just think that fasting is 'starving'. Any suggestions?
First, thank you for sharing your experience. 50 lbs of sustained body fat loss seems impossible for some people especially those who have already yo-yoed several times due to the outdated and harmful "eat less, move more" mantra of the past 5 decades. Family and friends might not respond to hearing about fasting until they see the sustained healthy results. Three things that seemed to have helped me in at least getting my family to stop worrying or intervening when I fast is to: 1) make sure that they see me eat well as I do eat well when I eat. 2) get as knowledgeable as possible so that I could articulate the science when asked and give reliable resources (Dr. Fung's books, various studies, Dr. Bikman, etc), 3) check and share my blood glucose and ketones whenever asked (I bought a keto mojo for this). My family learned pretty quickly that a blood sugar of 60 and even lower with high ketones was normal for me on an extended fast and by no means unhealthy. It has been a long time.. maybe even a full year since I have been asked to check my glucose. If there is a family member who you are particularly concerned about who needs to lose weight/ reverse diabetes 2 but sees fasting as "starving", encourage them to do TRE (time restricted eating). Have them read books and listen to lectures by Dr. Satchin Panda. SOOO helpful.
@@AzaleaBee I did the same amount, in about a year, at the age of 67. It blew my mind. Maintaining pretty well, with some sugar issues still to deal with. I'm very grateful for his and others' (Sten Ekberg, for example) information and encouragement.
A lot of people just want the easiest answer and if it doesn't sound easy they instantly shut off. What's crazy is that fasting actually _is_ the easiest answer, but in truth many people want to be told 'you can eat whatever you like whenever you like with no exercise and lose all the weight' lol. Or like "just drink this one tea each day with your regular meals and you'll lose weight". If someone is genuinely serious about wanting to lose weight and asks advice from someone who has lost weight, they _will_ look further into it even if they ultimately decide it's not for them. If they dismiss it instantly without even trying to learn about it, they're probably not serious!
Back in the day, delaying a meal is torture on high carb diet! I would not be able concentrate, I would have a headache and feel terrible. If I restricted calories, I felt cold and terrible. Low carb diet made such a difference. Much easier to skip a meal and to not eat when not actually hungry. Dropped 30 lbs in 2011 and kept off, no suffering. Don't really miss those high carb foods as long as I don't eat the high carb foods and keep away from the fake sweeteners 95% of the time. Love all of your books Dr. Fung.
This a great talk. Thank you for explaining fasting so well. 😊 I've been doing intermittent fasting for over a year, done a couple of 72 hours and find it really helpful in maintaining my weight. I lost about 1 stone, but more than that, I feel healthy.
@Jason Fung could you do a series on “what the gut knows”? had a breakthrough experience because of fasting, that I didn’t expect to happen. I only ever crave sugar and it is unceasing. While I was sick with the flu I suddenly had an intense craving for fresh cranberries, raw blueberries. I was actually salivating. I walked by the EmergenC and thought I would faint. So I brought the items home and feasted heavily on them alongside my dinner. The next day I had the most thorough cleanse and I am recovering, and no longer craving vitamin C foods. I don’t crave sugar, either! I feel the wisdom of my gut has returned, the real “Intuitive Eating.” I’d love to hear what you know on the subject
Thank you Dr Fung! Your guidance is priceless! ADF sounds really doable. As an older woman with celiac like inability to tolerate wheat and gluten and a family history of diabetes, obesity and heart disease I lost 34 pounds in three months doing IF and limiting carbs. That was more than a year ago and even though i’ve relaxed my restrictions the weight is staying off. My only issue has been some IB which I treat with a quality probiotic and at times a half dose of lomotil. I don’t hear of others having this problem so it must be specific to me. I would suggest that anyone fasting should pay attention to getting adequate fluids and electrolytes. This helped me tremendously and I was never ever hungry. 😊
I did intermittent fasting 36/12 from the beginning of July of 2022 - the beginning of October 2022. I lost about 35 lbs. On the days I ate, I ate whatever I wanted. Some days I ate one meal, other days I ate throughout the day. I did discover that I actually wanted to eat healthier as time passed. I let vacation, and then a illness in the family derail me for a time. I am now getting back to my every other day fasting. I have fasted days here and there, but have found it difficult to get started again, but today is the day. I will not stop this for even vacation. If I do have some special event come up I do allow myself salad and or soup on a fast day.
Phonetica, just water for the 7 days? You have super powers! I am planing on 5 day fasting. This is my second day. I am cooking a vegetable broth( celery, parsley, ginger, cumin and salt). Fingers crossed. Did you drink electrolytes? Congrats on your accomplishment! Keep it up!
Just to add my 2cents here but I am down 40+ kg’s and really FINALY starting to get stronger again. I can see my body form once again and it makes me smile when I walk past a mirror or store window these days. Don’t really exercise a lot but do like to walk for kilometres and swim, suck at swimming as I sink easy 😢😂. 70 years old now and went animal based when my mother died when I was 64 and it was type-2 that ate her up. Horrible way to go ay 😢😢😢. Dr Fung was the first guy I listened to talk about this and had my eyes opened wide and my brain 🧠 came alive. Didn’t make any friends as many family members are in the medical field (FTA). Carnivore and fasting saved my life or at least extended it a lot! Feeling more and more like I can live to 120 these which some data says we should be able to live to.
Thx for helping so many people including myself to fix our health. Im helping others by sharing this info, hopefully they act on it and repair thwir bodies too.
Thank you very much for speaking the truth against money lovers who have not been telling the truth . They also know the truth but continue the contrary
@@SoniaAzam7 I drink water, sparkling water and water with lemon. I take a calsium magnesium B12 supplement, NAD+ and a multi vitamin . My elevevated taste for bitter makes coffee undrinkable so I drop that.
At our workplace, the admins of the meeting have the capability to mute all participants. Maybe a good upgrade for your meeting service. If we blame the people who didn’t mute themselves, It’s like blaming the 95% you spoke of, when we know they were setup to fail.
I have been subscribed to your channel for three years now and continue to benefit from your research. Thank you Jason for imparting sensible information in a simple and straightforward format.
Thanks Dr Fung, knew you from Dr Berg interview you video, i been following both Dr video have helped me to improve my health a lots 🙏👍. thankyou so much to you both God bless you ❤️
Dr fung. Intermittent fasting has helped me manage my relationship with food. Now I am at 20-4 intermittent fasting. I would like to move to 24+ hour fasting but I not able to get over sleeping hungry. Will you be find enough to make a special video or write book/article around 24+hr fasting. Thanks again for your help.
Thank you Dr.Fung, common sense, very easily explained by Dr fung, artificial sweeteners will open the appetite, it's the habit, it's all about profit $$ Dr.Fung
I owe my life to you started IF in September. Went from a Large to a Medium. Even now medium is too big. I might have to size down to a small. My blood pressure went from 150/90 to 106/67 I have been doing IF + “low carb” not keto. I think keto is stupid. Low carb for me is 100g because the standard American diet is 250mg-300mg. I found this life style to be easier as I like to eat at night anyway. So no more snacking at night. I’m much too full.
One month ago my blood results showed an AIC of 9.1, blood sugar of 279, and triglycerides of 1023. Three weeks of intermittent fasting, low sugar, and low carbs and the numbers were lowered to blood sugar of 129, and triglycerides of 453 - A1C is still 9.1, but I am confident that will be in the normal range in three months.

After trying different eating patterns (my italian style 3 square meals a day, more frequent meals, classic 16hrs intermittent fasting etc...) that didn't feel right to me, I'm now eating 2 super filling, complete and nutrient dense meals a day, one in the morning and one in the evening (for ex. 8 am & 8 pm). This way there are two 12hrs gaps between my fed states and my body has the time to actually use those calories for energy during day and night. I believe in the equilibrium of equally balancing fed with fasting state because I'm so afraid of insulin resistance and what it can cause. Just a different point of view, since almost nobody is talking about skipping lunch in the IF community 🥰
@@saragentilepulcino 12 hours could be enough for some people. But for others more time is needed to make a difference. People who are obese, varying degrees of insulin resistance over x amount of time, age,... all can be factors. If it is working for you, great. But also consider the future which could change your insulin response based on above factors.
Skipping breakfast is way easier for me. I don't eat till noon and it's a zero carb meal, then nothing after my 5pm meal, which is very low carb. Then I go to bed at midnight and up at 7 or 8 am.
Dr. Fung, I have gallbladder stones. My gastroenterologist says I shouldn’t fast, but I feel good when I go :( I’d appreciate any info on fasting and gastro issues. Thank you in advance

What is particularly noble about Dr. Fung is that this information is put on UA-cam for anyone to find and use and benefit from. Its not behind a paywall, its not a commercial for buy my product, its just out there for anyone to use and get healthy. If only I had this information 10 years ago. I only recently discovered Dr. Fung in June of '22, but have lost over 70 pounds since then.
Having watched almost all of the videos by now, I can't help but grin a tiny bit when Dr. Fung sounds a little exasperated at trying to say nicely for the 1 millionth time, "your eating to darn much!". I guess this is pretty much what ever doctor goes through with their patients. 😀
@Kent
You asked how I lost the weight, I fasted and walked an hour or so everyday.
I eat my last meal Sunday night, and then fast until Friday morning. I stay hydrated with water or tea, and take salt + an electrolyte supplement everyday. I tried various combinations of alternate daily fasts, but I was hungry all the time. Sunday to Friday just turned out to be the easiest, least complicated way to do the fast.
In the beginning I was losing about 5ish lbs a week, but after about 6 months I'm only losing 2ish lbs a week. Though I have no way to measure, I don't feel like I've lost much if any muscle.
The first week wasn't much fun adjusting to fasting, but 6 months later, its easy peasy.
Yes, I agree with you. It's awesome that Dr. Fung give out all this information for free UA-cam. He really just wants to help people
@@real_chaorders Honestly, its easy peasy. From a physical point of view, I'm not hungry, I have tons of energy and truly, Monday through Thursday I feel great. Physically I feel like I could go a week or more without food.
Its the mental challenge is what's so difficult to overcome. By Thursday night my brain just won't let up thinking about food. And trying to get any sleep Thursday night is just a exercise in futility, I toss and turn all night. I'm guessing its because of the counter regulatory hormones.
Once I start eating again on Friday I feel awful. Its like how you feel after eating that huge thanksgiving meal, except I feel that way all day Friday. But at least I sleep great Friday night.
Sat and Sun I do ok, I just feel normal again, then Monday and Tuesday I don't even want to look at food. 😎
he doesn't say "you're eating to darn much!" at all though.. i guess fasting may reduce energy to the brain haha
Maybe you could buy his book "The Obesity Code" to reward Dr Fung.
And, this is not the case of Fung, but don't think that many doctors have feelings for their patients. You're just like a broken car which you bring or repair at the repair shop. Actually you give them work. Think about how much money Eli Lilly is making with insulin. The price has skyrocketed through the years !
I’m on day three of starting 16/8. I went to visit a friend and they offered me two of the things I love most. BBQ potato chips and peanut butter cookies. I wasn’t hungry and I managed to not eat any of it. It was tough. But I kept telling myself I wasn’t hungry and succeeded in not eating any of it. 🎉
Good on you.

11:32: ! Calorie restriction leads to a decrease in metabolic rate, limiting body fat loss.
16:38: 🍽 As energy drops and metabolic rate decreases, hunger levels increase due to higher levels of ghrelin hormone.
22:08: 🔥 Fasting increases noradrenaline levels and switches the body's fuel source from food to stored body fat, leading to increased energy expenditure.
27:22: 🍽 Skipping dinner allows your body to use stored fat for energy and reduces hunger levels.
32:24: 🔑 Controlling hunger is more important than controlling diet for weight management.
38:01: 💡 Fasting is a natural and beneficial part of our physiology that can be done by both males and females without any harm.
43:22: 🍽 Fasting is more important now than ever due to the prevalence of obesity, type 2 diabetes, and metabolic disease.

Great job.. this is the summery
You saved my life Dr Jason Fung 🙏 lost 25 kgs and control my T2 diabetes with no meds... Got your book for a present.. life changing
Congratulations on your weight loss and improved health. Which book of Dr. Fung's did you read? I recommend his The Diabetes Codd even for non-diabetics.
@@AzaleaBee Was going to recommend it haha , loved the book read it with so much curiosity .
Congratulations to you! 👏🎉I'm with you! His book The Obesity Code. It changed my life. Thanks for sharing your story.
were you following low carb or just fasting
I have followed Dr Fung for 7 years and I lost weight and a ton of inches
Dr Fung just keeps honing this message - still getting better every time he does it !
Also, the person interrupting the audio is clearly not following the presentation (and requests for muting) , so next time, just kick them off.
The book, "The Obesity Code" is truly life changing and should be required reading for all adults.
So great to spend a Sunday afternoon settling in and watching a Dr. Fung lecture! (Better than the Packers today 🤪😅!).
I remember when I started watching almost two years ago I was wondering if all this was really true and worked but felt it was worth a try.
Now, I watch and think "Yes! That's so true! That's exactly what happens and how it works!". I'm 59 and I've lost over 150 lbs. and have been maintaining it well since then. The transformation has been profound. I did it all on my own, just by following and reading Dr Fung's books. I'm off my blood pressure meds, my osteoarthritis pain is so much better and my asthma is gone. I'm so thankful. Learning to fast changed my life.
Thanks again for all you do 😊🙏
Awesome! Congratulations! Try Carnivore Diet for the osteoarthritis.
just awesome 😎 !
@@AndrewEvenstar 👍❤️
Outstanding effort and result!
Amazing! Truly amazing! I only needed to lose 10 lbs that stuck with me for 10 years. Gone, at 67!
I'm eternally grateful for this knowledge. This is the 1st time in my life that I've felt in control of what I eat and weight loss. Haven't binge eaten since Intermittent fasting and cutting refined carbs and sugar. I could almost cry of happiness.
That’s wonderful and let all the happiness out -cry. This is cleansing for the soul.
@@ladyc9188yes, not only dr fung heals our body, he bless our soul also with his kindness.
In 2018, I did not know what to do anymore to lose weight. I was browsing again to find a new option and - THANK GOD! - I found Dr Fung´s book "Obesity Code". Since then, I started fasting and my health is much more strong today. I´m sure, one day, all the world will accept the truth of what Dr Fung is saying. Thank you, Dr Fung for sharing your knowledge and keep fighting for the Truth. You are saving lives. God bless you!
This was a fabulous video- minus the rude interruptions .
Dr Fung Deserves s’more Respect Than That.
Those interruptions were so frustrating
i cant thank u more . i was 75 kg when i thought of getting in shape aroung 68kg .i tried all things in between but always my weight kept on increasing . same when i saw my weight 83 kg , i thought lets do it now or i will surely face health problems . but again it went to 92kg . then i found u and watching your videos again and again helped me to understand root cause . now after 4 months , i have lost around 15kg , still doing .. but loosing weight was not so much easy and fun before u sir . thank u for changing my life forever . i cant describe in words what your videos helped me .. thnq u sir much love
80 days ago, I was one reading all of the comments on several of Dr Fungs videos thinking; there is no way this many people have been healed from not eating.
70 days after starting IF, I’m 60 lbs down, BP in check, A1C in check, foot fungus gone, skin issues gone, my addiction to food I didn’t know I had is cured. I’m feeling so much better about myself and can’t wait until I loose the remaining 40 pounds to get to my goal of 210
Thanks so much Dr Fung. I owe my life to you
So great to hear!!!
You lost nearly 1lb a day for 70 days?
@@t1mmytiger I do not even believe they lost 60 lbs in 70 days BS
@@trishkline6507 If you start out severely overweight, 60lbs in 2-3 months is entirely plausible. I lost 20lbs in my first 3 weeks of fasting a few years ago.
@@t1mmytiger yes. I have a smart scale and if there was a way to post a screen shot of it, I would. Like I said in my post, I was reading the comments and thinking there was no way. I also was 310 pounds and high body fat %. My body was in so much stress, I could barely walk up 2 stairs without getting winded. Best of luck to you and your journey!
I've added this to my Dr Fung Lecture Playlist. I use it to refresh my understanding (I have your books plus the Audible recordings). It's great when I traveling and send to friends to share what I've done to reverse and reclaim my health and debunk their view of Type 2 being a progressive chronic disease and their "essential" Hypertension. Thank you
I have a similar playlist and added this Dr. Fung interview that I stumbled on this morning.
It's comprehensive and just as in this video Dr. Fung is quite relaxed.
ua-cam.com/video/36oVGVokcNQ/v-deo.html
Can you just explain what you mean by 'their "essential" Hypertension'?
@@finosuilleabhain7781 I was hoping the OP would answer this for themselves, but since they haven't I'll just mention that "essential hypertension" (primary hypertension) is basically hypertension that can't be linked to a specific cause like injury etc. Physicians often link it to genetics and sometimes just say it is inevitable with age.
If you google the term, you can learn about it in more detail.
@@AzaleaBee Thanks, Azalea. I'd have done so straight away had I thought it might be a term, but was thrown off that scent by the combination of 'their' and the quotes around 'Hypertension', which led me to wonder quite what the OP's friends might have been saying about the subject. It's called overthinking, I believe. Thanks again - most helpful of you to have stepped in.
Great!
I just read the cancer code book.....it's amazing......thanks for all you do....now reading the obesity code...
stay well Dr. Fung!
Obesity Code is also amazing.. love it!
Really good information, I've been running 16/8 IF for 3 weeks , dropped 11 lbs, feel very good, going to plan on it just being what I do going forward.
I started listening to Jason Fung a year ago. Him and Dr. Berg have literally saved my life. Thank you!
They are both amazing and truthful gentlemen and have saved my life by the grace of God
Thank you, such a great explanation, I just did a 48 hr fast over my weekend. I sometimes feel a bit tired during my fasts, but when I stop and re feed I’m bursting with energy. Love fasting ❤
Sounds almost like you do not like it. "I feel better when I eat? Just go through 2 days of pain while I work". You may want to look into your diet when feeding. On average you energy levels should be increasing. Sounds like diet is poor or you eat in excess during your feeds. Should be able to find info on that.
Thankyou so much Dr.!! You have changed my life! After 3 months I have lost 30 lbs and I'm no longer pre-diabetic, my thyroid is back in normal range, my joints don't hurt and my plantar fasciitis went away!! I read the Obesity Code and have followed your videos and learned so much and it all makes perfect sense. I'm currently doing OMAD (one meal a day) one big meal, and try to eat healthy but still eat whatever I want. I've learned to keep my sugar and carbs low and it totally made a difference. I can't thank you enough!
I have plantar fasciitis and am looking for a solution and came across your story. This came at the right time. Thank you!
Absolutely stunning. The information you give out for free is live saving, but unfortunately not shared by any „normal“ physicians. But that’s okay. We know better.
I think it’s beginning to be shared by other physicians. My doctor read me the riot act over my diagnosis of non-alcoholic fatty liver. She referred me to Dr. Fung’s videos. My husband and I have now lost 12 and 10 lbs respectively in two weeks.
Hello Dr. Fung, Thank you very much for promoting a healthy lifestyle and fasting to cure Type II diabetes. I am a big fan. I just did a 24-hour fast yesterday and lost 2 pounds. I was slim until I gave birth to two children and hit my mid-40s. I have been struggling with weight loss/weight gain cycles. Now I finally find a way to lose weight and keep slim.
Thanks so much for sharing, this really does work and he is so awesome and amazing and what he shares is so basic and it has saved my life
Perfect example of a way to breakdown a complex subject but make it sound obvious and simple. I have tried every diet under the sun in the past 10 years and IF is the only thing that just works and is easy. Now thanks to amazing lectures like this I understand the science properly and can openly discuss with evidence with anyone.
The only terribly sad thing is that you can't really commercialise fasting like you can juice fasting or gyms etc etc so there is so much vested interest in not publicising IF.
Dr.Fung Thank thank thank thank you for your earnestness and incredibly fine tuned message that this process WORKS.
I love Dr Fung's message each and every time I listen to him ! it's always relevant. It's always new to my ears. I love all of his messages and think that one day the entire world will wake up and take this on board too. Thank you so much Dr Fung 🙂
Thank you for all your diabetes informational videos explaining the necessary dietary components of preventing & reversing excess blood sugars causing insulin resistance Diabetes 2 metabolic syndrome. It’s just so very hard to UN-learn a lifetime of incorrect eating. Thank you again.
Wow...I'm 51 and the "eat less, move more" idea has ruled my life for 30 years. I just sucked up the fact that I was hungry all the time and it "worked," until I regained and did it again, just as you said. I found out about intermittent fasting 3 weeks ago and have done OMAD 75% and 18:6 the other 25% of that time, and I've lost 6 lbs! And I'm totally satisfied, hardly any hunger and my one meal is literally all I can eat at once. I feel great and see that my goal is not only in view but I'll never regain, again!!!! I might have to increase to two meals a day; I can't keep losing 2 lbs a week for much longer...what a problem, LOL! Thank you for laying it out so clearly!
Thank you for another clear, concise explanation of how physiology relates to weight gain or loss.
Thank you so much, Dr. Fung. God bless you and your family! 🙏🏻
Thank you very much, Dr. Fung, you're the first true Dr. in the world. No other doctors have ever healed so many patients like you. You have treated millions of people over UA-cam exceedingly. Your videos will continue to do so for the rest of time. God bless you to live longer. You are a copy of Jesus
Doc .. you are a beacon .. cutting the stomach is so horrible, cannot reverse once your organ has been surgically reduced …. So well spoken, so true.
If I could go back 8 yrs, I wouldn't have done VSG. I agree with this.
I had it done in 2001, if I had found IF I NEVER NEVER would have done that to myself but I was so desperate!!! I did lose 130 pounds but with IF I have lost 70 pounds in 7 months😊
This was awesome. Started 3 day fasts 3 months ago. Excluding feasting over Xmas/NY (still low carb). Down 10kg. It's been an easy thing to do 🙌
Thank you so much for having this You Tube channel and sharing your knowledge with the general public!!
Your videos have changed my life......thanku dr Jason
I’ve been listening to you and others’ Keto and fasting videos since October 2021. I started intermittent fasting in March 2022 and on and off extended fasting in August 2020. I agree 100% about hunger pains (waves) passing during short and extended fasting but you are the first to explain why very simply. To paraphrase your explanation, when not fasting, you get hungry, you eat, the hunger goes away. When fasting, you get hungry on and off during your fast and your body starts eating your stored fat and the hunger goes away.
Two questions
1. Will fasting help fight Diabetes Type 1?
1. Will a 72 hour or longer fast, resetting your immune system, help fight the HIV/AIDS virus?
Thank you for all your videos
Dr. Fung is a true legend 🙌🏻🙌🏻 Thank you so much!!
Jason you legend!! Tuning in at the end of my fasting day ;)
Thank you for speaking the truth--- especially what you said at the end. ❤❤❤❤❤
Shame on people who join a meeting and don't even pay attention to the fact that their microphone is not on mute as it should always be.
Such an educational video! Great stuff. Question... have you ever tried Next Level Diet? I got a fat-loss meal plan from them and I love it.
You are one of my heroes, Dr Jason! I have been trying to help someone( in her 50’s) who wants to lose weight and is trying to use the Dr Adkins book. She is TYPE 1 DIABETIC. she gets scared if she tries to skip breakfast, and I never hear you talk about type 1 diabetics and fasting. She is overweight but not obese.
I heard dr Bernstein does low carb eating and fasting specifically for type 1 diabetics. Check him out
I began 16/8 intermittent fasting, 2mad, carnivore diet except include string beans, eggplant, broccoli, cauliflower, and cabbage in my diet. I increased exercise daily but not much. I eat until I am full and after 2 wks I feel better. At 75 I want to reverse type 2 diabetes, bring 6.9 a1c down and lose weight. I am 220 lbs and want to lose 30lbs. Thanks to your advice I find it stable regardless what restrictions others offer online. I have a dr appt in 6 wks and hope this will show improvement of my 5’8” female person.
Thank you for giving me my youth back DR Fung !
I lost 100 lbs in 4 months. 36 hour fast then intermittent fasting while eating very low cal diet. Rode my bike a couple times a week about 45 min each time and paddled my kayak for fun on Saturday and Sunday. I was never starving !!!!! I’m 62 and 209 lbs. Iv kept it off over a year now. Thank you sir !!!
Ps. Never drank water, two to 3 Liters of Diet Coke a day. Been doing this for over 34 years !!!
Thank you sir for posting this!!!!! I have been begging for help through diet and exercise for a very long time. All the Drs want to do in give me a pill or have me follow the diet that you mentioned is "surface knowledge". I have NAFL and a calcium deposite in my aorta. I refuse to take a statin, because I want to lose weight and correct these issues using a more natural process. I have now put your site in my Favs. I wish you had a practice here in my hometown of Greensboro, NC! But I am so glad to finally find someone with sensible information. Thank you !Thank You! Thank you!
Fffffuuuuuunnnnnnnggggggg! Thanks for answering so many questions I had and explaining so many factors involved in IF. With such a clear and concise presentation as well.
I have tried fasting for a year.. and I love it… I just lose discipline and go back to overdosing on carbs every other month… currently attempting a 7 day fast (water) hoping it will help me to be more disciplined with OMAD. I’m 60 hours in out of 178 but feel good about this and Dr Fung was the first I ever heard about Fasting… Thank you Doc
Listening to this at work became I really wanted some chips but didn’t want to break my fast 😅
Keeping it real😃
thank you 🙏 you save my life i was diabetic and 204 pounds when see your first video i say maybe i can make it and i bay your book i started festing and keto 2 years a go now i’m free diabetic and 145 pounds very healthy i still doing i change my lifestyle and my husband we doing to gather i’m eating only one times they never getting hungry.thank you 🙏
It's so amazing that it is just one level deeper than anyone thought, not reduce the food, it's reduce the frequency! wow!
I'm fasting right now. Jason Rocks!!!👍👌🥂
me too!!!!
Excellent review.
I'm more than 4 1/2 years into a super low carb and intermittent fasting way of life. I've lost 105 pounds and at 65 feel like I have a new lease on life. Thank you for all you do!!!
Didn't your metabolism slow ? Thanks ! :)
@@ouidabordji6438 Absolutely not! If you're adapted to burning fat instead of glucose for fuel, your body happily does so. If you eat all the carbs, then you never adapt to be a fat burner, your body stays a glucose burner, constantly burning those carbs demanding more and more, and your metabolism slows because on your "eat less, move more" way of eating your body fears famine and starvation. I've yo yo dieted from age 15 to 61 and that way never works (for me at least no more than 6-9 months) . Cutting carbs way down (for me almost always under 20 whole carbohydrates a day) and intermittent fasting are the only things that work. My intermittent fasting is 1-2 meals a day with at least 16 hours between supper of the eaving to lunch the next day. No long term fasting for me as I'm on blood thinners permanently and 24 hours is my limit without food or it seriously messes with my dosages. If I can do this after 55 years of fighting fat ( most years morbid obesity) anybody can!!!
Dr Fung is a genius that has not fallen to the FDA and is not not not afraid to tell us what is happening in our bodies. I have a Masters in Hormones now. And I thank you!!$
Thank you Dr. Fung for all your videos, I lost 40 pounds using the 16/8 method and feel great!
Thank you for posting a nice summative refresher video. I started watching Dr. Fung about two years ago and I think I've watched every video and I've read almost all his books - you're an absolute life changer. I lost 50lbs and it has not come back even with going on holiday for a month (went to visit family after four and half years) and now fasting is just my normal eating patterns. Thank you Dr. Fung, you are literally a life saver for so many!!
I would like to know how to share this with friends who often ask but when I tell them I fast they almost immediately get defensive and say "oh I could never do that" or "I have to have eat (generally carbs) or my blood sugar drops and then I'm weak" etc. I haven't figured out how to respond to this in a positive way so I just let it go. I've tried explaining the science behind it but it falls on deaf ears, my guess is because they just think that fasting is 'starving'. Any suggestions?
First, thank you for sharing your experience. 50 lbs of sustained body fat loss seems impossible for some people especially those who have already yo-yoed several times due to the outdated and harmful "eat less, move more" mantra of the past 5 decades.
Family and friends might not respond to hearing about fasting until they see the sustained healthy results. Three things that seemed to have helped me in at least getting my family to stop worrying or intervening when I fast is to: 1) make sure that they see me eat well as I do eat well when I eat. 2) get as knowledgeable as possible so that I could articulate the science when asked and give reliable resources (Dr. Fung's books, various studies, Dr. Bikman, etc), 3) check and share my blood glucose and ketones whenever asked (I bought a keto mojo for this). My family learned pretty quickly that a blood sugar of 60 and even lower with high ketones was normal for me on an extended fast and by no means unhealthy. It has been a long time.. maybe even a full year since I have been asked to check my glucose.
If there is a family member who you are particularly concerned about who needs to lose weight/ reverse diabetes 2 but sees fasting as "starving", encourage them to do TRE (time restricted eating). Have them read books and listen to lectures by Dr. Satchin Panda. SOOO helpful.
@@AzaleaBee I did the same amount, in about a year, at the age of 67. It blew my mind. Maintaining pretty well, with some sugar issues still to deal with. I'm very grateful for his and others' (Sten Ekberg, for example) information and encouragement.
A lot of people just want the easiest answer and if it doesn't sound easy they instantly shut off. What's crazy is that fasting actually _is_ the easiest answer, but in truth many people want to be told 'you can eat whatever you like whenever you like with no exercise and lose all the weight' lol. Or like "just drink this one tea each day with your regular meals and you'll lose weight". If someone is genuinely serious about wanting to lose weight and asks advice from someone who has lost weight, they _will_ look further into it even if they ultimately decide it's not for them. If they dismiss it instantly without even trying to learn about it, they're probably not serious!
@@AzaleaBeeabsolutely right about that
You have helped me so much over the years …. Thank you 🙏 ❤❤❤❤
Back in the day, delaying a meal is torture on high carb diet! I would not be able concentrate, I would have a headache and feel terrible. If I restricted calories, I felt cold and terrible. Low carb diet made such a difference. Much easier to skip a meal and to not eat when not actually hungry. Dropped 30 lbs in 2011 and kept off, no suffering. Don't really miss those high carb foods as long as I don't eat the high carb foods and keep away from the fake sweeteners 95% of the time. Love all of your books Dr. Fung.
I agree. I first had to get a handle on drastically reducing carbs, then added IF. Would have been very difficult if I had still been a carboholic.
It works! Just a million congratulations on your excellent research!!!! From Crete island just a wish, stay healthy and keep up the excellent work!
This a great talk. Thank you for explaining fasting so well. 😊 I've been doing intermittent fasting for over a year, done a couple of 72 hours and find it really helpful in maintaining my weight. I lost about 1 stone, but more than that, I feel healthy.
What is a stone please
@Jason Fung could you do a series on “what the gut knows”? had a breakthrough experience because of fasting, that I didn’t expect to happen. I only ever crave sugar and it is unceasing. While I was sick with the flu I suddenly had an intense craving for fresh cranberries, raw blueberries. I was actually salivating. I walked by the EmergenC and thought I would faint. So I brought the items home and feasted heavily on them alongside my dinner. The next day I had the most thorough cleanse and I am recovering, and no longer craving vitamin C foods. I don’t crave sugar, either! I feel the wisdom of my gut has returned, the real “Intuitive Eating.” I’d love to hear what you know on the subject
God sent information. Thank you.
Just came off my first 72hr fast, not easy but I did it. Thank you Dr Fung!!!!
Great I'm doing 48 hours fast every weekends. But to move towards 72 hour's still not prepared
The more I do it the easier it got.
God bless you Dr. Fung!
Thank you Dr Fung! Your guidance is priceless! ADF sounds really doable. As an older woman with celiac like inability to tolerate wheat and gluten and a family history of diabetes, obesity and heart disease I lost 34 pounds in three months doing IF and limiting carbs. That was more than a year ago and even though i’ve relaxed my restrictions the weight is staying off. My only issue has been some IB which I treat with a quality probiotic and at times a half dose of lomotil. I don’t hear of others having this problem so it must be specific to me. I would suggest that anyone fasting should pay attention to getting adequate fluids and electrolytes. This helped me tremendously and I was never ever hungry. 😊
Jason, I appreciate everything you have written and shared in your podcasts.THANK YOU SO MUCH!
I did intermittent fasting 36/12 from the beginning of July of 2022 - the beginning of October 2022. I lost about 35 lbs. On the days I ate, I ate whatever I wanted. Some days I ate one meal, other days I ate throughout the day. I did discover that I actually wanted to eat healthier as time passed. I let vacation, and then a illness in the family derail me for a time. I am now getting back to my every other day fasting. I have fasted days here and there, but have found it difficult to get started again, but today is the day. I will not stop this for even vacation. If I do have some special event come up I do allow myself salad and or soup on a fast day.
I did my first 7 day water fast a couple weeks ago. I was barely hungry by day 7, and couldn't eat much when I did eat. Amazing stuff
Phonetica, just water for the 7 days? You have super powers! I am planing on 5 day fasting. This is my second day. I am cooking a vegetable broth( celery, parsley, ginger, cumin and salt). Fingers crossed.
Did you drink electrolytes?
Congrats on your accomplishment! Keep it up!
Massive well done!
Why?
@@Charles.Wright Ketogenic diet, and doing 24-48 hour fasts.
@@bivianadifruscio9701 Yeah I supplemented with LMNT electrolytes
Just to add my 2cents here but I am down 40+ kg’s and really FINALY starting to get stronger again. I can see my body form once again and it makes me smile when I walk past a mirror or store window these days. Don’t really exercise a lot but do like to walk for kilometres and swim, suck at swimming as I sink easy 😢😂. 70 years old now and went animal based when my mother died when I was 64 and it was type-2 that ate her up. Horrible way to go ay 😢😢😢. Dr Fung was the first guy I listened to talk about this and had my eyes opened wide and my brain 🧠 came alive. Didn’t make any friends as many family members are in the medical field (FTA). Carnivore and fasting saved my life or at least extended it a lot! Feeling more and more like I can live to 120 these which some data says we should be able to live to.
Thx for helping so many people including myself to fix our health.
Im helping others by sharing this info, hopefully they act on it and repair thwir bodies too.
I hate it when I'm on a work call and the dogs get loose 🤣
Dr. Jason you`re the best, thanks for all the information that you are sharing and explaining to us.
Amazing as always Dr.
Thank you very much for speaking the truth against money lovers who have not been telling the truth . They also know the truth but continue the contrary
Exceptional break down, Bruh. Thank you 🤙🏾
Day 70 of full fasting and I lost 52kg.
No food since 8 August and I feel great.
You opened a whole new world to me.
Thank You Dr. Jason Fung.
Wow that’s amazing! How have you managed so many days? What fluids are you consuming
@@SoniaAzam7 I drink water, sparkling water and water with lemon. I take a calsium magnesium B12 supplement, NAD+ and a multi vitamin . My elevevated taste for bitter makes coffee undrinkable so I drop that.
Thank you Dr fung you inspire me to do intermittent fasting your amazing
LV LV LV your explanation Dr. Fung👏 🙌
I would like to see a video about fasting before & after surgery.
This man saved my life. Thank u so very much u beautiful human ❤
At our workplace, the admins of the meeting have the capability to mute all participants. Maybe a good upgrade for your meeting service.
If we blame the people who didn’t mute themselves, It’s like blaming the 95% you spoke of, when we know they were setup to fail.
Thanks for your videos. I just bought many of your books. Love the info. :)
Very informative. Thank you so much, Dr. Fung.
Thank you for your videos very informative
I have been subscribed to your channel for three years now and continue to benefit from your research. Thank you Jason for imparting sensible information in a simple and straightforward format.
Thanks Dr Fung, knew you from Dr Berg interview you video, i been following both Dr video have helped me to improve my health a lots 🙏👍. thankyou so much to you both God bless you ❤️
Good morning Dr.Fung thanks.
All awesome and great but mostly low voice of Dr Jason. Thanks
Dr. Fung, you're the best.
Great lecture.
Dr fung. Intermittent fasting has helped me manage my relationship with food. Now I am at 20-4 intermittent fasting. I would like to move to 24+ hour fasting but I not able to get over sleeping hungry.
Will you be find enough to make a special video or write book/article around 24+hr fasting.
Thanks again for your help.
Lots of content on IF offlate, but Dr Fung is The OG in the science of intermittent fasting.
Thank you Dr.Fung, common sense, very easily explained by Dr fung, artificial sweeteners will open the appetite, it's the habit, it's all about profit $$ Dr.Fung
I owe my life to you started IF in September. Went from a Large to a Medium. Even now medium is too big. I might have to size down to a small.
My blood pressure went from 150/90 to 106/67
I have been doing IF + “low carb” not keto. I think keto is stupid. Low carb for me is 100g because the standard American diet is 250mg-300mg.
I found this life style to be easier as I like to eat at night anyway. So no more snacking at night. I’m much too full.
Man, I loved this...and also I want to smack the people that cannot seem to grasp the idea of muting themselves. ;)
yes 👍 it's really works for me , wet fast or dry fast ...both works 🙋🏻♀️😁. from 87kag to 69kg in one year💃🏻👯♀️💃🏻👯♀️
One month ago my blood results showed an AIC of 9.1, blood sugar of 279, and triglycerides of 1023. Three weeks of intermittent fasting, low sugar, and low carbs and the numbers were lowered to blood sugar of 129, and triglycerides of 453 - A1C is still 9.1, but I am confident that will be in the normal range in three months. It is true - You are what you eat - and when you eat!
Thank you for the wonderful videos and they truly helped me to get my self sorted out Dr Fung . Blessings .
This timestamping should help:
00:16 🏥 *Weight loss, beyond aesthetics, is a critical aspect of public health, particularly linked to metabolic diseases like type 2 diabetes, contributing to conditions like heart disease and stroke.*
01:27 🍽️ *Standard weight loss advice, "eat less, move more," emphasizes reducing calorie intake and increasing exercise, assuming it leads to weight loss, but evidence suggests it's not consistently effective.*
03:59 📉 *Diet alone often shows minimal long-term weight loss benefits, with studies indicating decreasing success rates over time regardless of the diet's intensity.*
06:45 📊 *Traditional weight loss strategies based on "eat less, move more" have a failure rate of around 99.5%, showcasing their inefficiency for sustainable weight loss.*
08:10 🔄 *Decreasing calorie intake might reduce body fat or lower metabolic rates. Lowering calories doesn't guarantee fat loss; it can also lead to a decline in metabolic rates without fat loss.*
11:32 ⚖️ *Scientific studies consistently indicate that reducing calorie intake results in a decrease in energy expenditure, hindering long-term weight loss efforts.*
13:09 📉 *Significant weight loss often correlates with a substantial drop in metabolic rates, contributing to difficulties in maintaining weight loss over time.*
17:02 🍽️ *As individuals lose weight, hunger levels tend to increase physiologically, making sustained weight loss challenging due to heightened appetite even after weight loss.*
18:37 🍔 *Lower metabolic rates and increased hunger are physiological responses to calorie reduction, leading to weight regain, rather than merely a lack of willpower.*
20:41 🕰️ *Fasting serves as a natural balance between feeding and fasting, allowing insulin levels to drop, facilitating the utilization of stored energy for fuel.*
23:12 🍽️ *Fasting, as opposed to constant calorie restriction, can lead to increased metabolic rates and favorable hormonal responses that support accessing stored body fat for energy.*
24:06 🍽️ *Caloric deficit isn't the only factor in weight loss; it's a balance of energy in, energy out, and fat stores regulated by hormones like insulin.*
26:11 🍔 *Hunger during fasting periods doesn't increase significantly; ghrelin levels drop back to baseline even if meals are skipped.*
28:31 🍭 *Cutting out specific food cravings entirely is more effective than reducing them partially; cravings diminish after a complete removal of those foods.*
30:07 🌡️ *Reducing calories increases hunger significantly, while alternate daily fasting shows less increase in hunger levels.*
32:13 🏋️♀️ *Hunger and metabolic rates, not just diet control, are crucial in weight management; focus on managing hunger rather than controlling the diet.*
34:45 🏋️♂️ *Fasting doesn't lead to muscle loss; fat mass decreases while lean body mass is preserved due to hormone responses.*
36:36 🍲 *Fasting has been practiced in various cultures for millennia, debunking the myth that it's unsustainable or harmful.*
38:50 🕒 *Fasting is a simple, cost-effective, flexible, and powerful intervention for weight loss; it's more about when you don't eat than what you eat.*
41:39 💪 *Fasting is the most effective weight loss intervention as it's free of cost, has no lower limit, and allows continuous adaptation.*
43:01 🕰️ *Fasting is a tool for weight management used for centuries; it's more crucial now due to modern health issues likeobesity and type 2 diabetes.*
46:41 🍽️ *Average eating duration in North America is about 14 hours and 45 minutes, contributing to weight maintenance, but fasting for 16 to 24 hours can aid weight loss.*
48:29 🕓 *Popular fasting regimens include 16-hour daily fasts and 24-hour one meal a day schedules, but various fasting durations (20 hours, two days, three days, etc.) are possible.*
50:03 ☕️ *During fasting, black coffee, green tea, and water without additives are acceptable; coffee with cream, butter, or bone broth with calories may slightly elevate insulin but won't significantly disrupt fasting benefits.*
52:48 🍬 *Artificial sweeteners may not aid weight loss, as they could stimulate appetite, making fasting more challenging despite their lack of calories.*
54:39 🍽️ *Eating all daily calories within one meal while fasting isn't advised; the purpose of fasting is to restrict overall calorie intake and enable the body to burn stored fat.*
57:39 😴 *Fasting may occasionally affect sleep due to increased energy levels from hormonal changes, but adjusting eating patterns often resolves this issue.*
59:02 🍟 *Food industry strategies, promoting snacking and processed foods, significantly influence eating habits, research, and dietary guidelines, leading to potential conflicts of interest in nutrition studies.*
01:04:05 🩸 *Fasting allows the body to burn stored glucose, aiding in weight loss, thereby helping reverse Type 2 diabetes by depleting glucose stores and promoting fat burning.*
01:07:03 🚫 *Certain groups like pregnant or breastfeeding individuals, underweight individuals, and growing children should avoid extended fasting; fasting is a tool, and its implementation should consider individual health conditions.*
Wonderful talk by Dr Fung! Shame people don't know how to use a mute function! Get some manners!
After trying different eating patterns (my italian style 3 square meals a day, more frequent meals, classic 16hrs intermittent fasting etc...) that didn't feel right to me, I'm now eating 2 super filling, complete and nutrient dense meals a day, one in the morning and one in the evening (for ex. 8 am & 8 pm). This way there are two 12hrs gaps between my fed states and my body has the time to actually use those calories for energy during day and night. I believe in the equilibrium of equally balancing fed with fasting state because I'm so afraid of insulin resistance and what it can cause. Just a different point of view, since almost nobody is talking about skipping lunch in the IF community 🥰
That could be because eating every 12 hours is contributing to insulin resistance. Continue listening to and learning from Dr. Fung.
@@kristenmeyers7362 with a 12 hrs period insulin has plenty of time to go down e remain low for a while actually
@@saragentilepulcino 12 hours could be enough for some people. But for others more time is needed to make a difference. People who are obese, varying degrees of insulin resistance over x amount of time, age,... all can be factors.
If it is working for you, great. But also consider the future which could change your insulin response based on above factors.
I decided to skip breakfast simply because I wasn't really hungry then. Whatever works for you.
Skipping breakfast is way easier for me. I don't eat till noon and it's a zero carb meal, then nothing after my 5pm meal, which is very low carb. Then I go to bed at midnight and up at 7 or 8 am.
Dr. Fung, I have gallbladder stones. My gastroenterologist says I shouldn’t fast, but I feel good when I go :( I’d appreciate any info on fasting and gastro issues.
Thank you in advance
Great info as always!!! Need to have a moderator who can mute people on these thought, that was pretty distracting.
