- Опубліковано 21 лип 2024
- I’m diving into the fascinating concept of the body’s set weight, which acts like a thermostat for our body fat. Ever wondered why it’s so hard to lose or gain weight? I’ll explain how this body fat thermostat changes everything you know about weight loss.
In this video, we'll cover:
Body Set Weight - Understand how your body controls fat like a thermostat.
Homeostatic Mechanisms - Learn how our bodies automatically adjust to changes.
Calories vs. Hormones - Discover why “calories in, calories out” isn't the full story.
Real-life Examples - See how historical figures stayed fit despite food availability.
Scientific Studies - Explore research proving the existence of this body fat thermostat.
Hormonal Influences - Find out which hormones affect your body’s set weight.
I’ll break down complex ideas with simple examples, like comparing your body to a room with a thermostat. Whether you’re trying to lose weight, gain weight, or just understand how your body works, this video is packed with easy-to-understand information.
Don't miss out! Hit play and learn how to adjust your body’s thermostat for better weight management. Remember to like, subscribe, and leave a comment with any questions or topics you want me to cover next.

Good information, as always. But...the stupid faces!
Mean BMI was lowest in vegans (23.6 kg/m2) and incrementally higher in lacto-ovo vegetarians (25.7 kg/m2), pesco-vegetarians (26.3 kg/m2), semi-vegetarians (27.3 kg/m2), and nonvegetarians (28.8 kg/m2). Prevalence of type 2 diabetes increased from 2.9% in vegans to 7.6% in nonvegetarians; the prevalence was intermediate in participants consuming lacto-ovo (3.2%), pesco (4.8%), or semi-vegetarian (6.1%) diets. After adjustment for age, sex, ethnicity, education, income, physical activity, television watching, sleep habits, alcohol use, and BMI, vegans (OR 0.51 [95% CI 0.40-0.66]), lacto-ovo vegetarians (0.54 [0.49-0.60]), pesco-vegetarians (0.70 [0.61-0.80]), and semi-vegetarians (0.76 [0.65-0.90]) had a lower risk of type 2 diabetes than nonvegetarians.

Jason, why not just tell people the truth? The thinnest healthiest longest living populations eat a lower caloric density diet...
When we eat heavy weight gain might be a constant challenge .... There are no thin healthy long living populations where everyone is thin eating heavy ....
This may be unpopular to say... But why not say the truth and let the chips fall where they may..
@@mysticjedi6730 Maybe, because we are not healthy on just plants.
@@jdilksjr my comment was about calorie density.
Looking at the china study, the Oxford epic study, the seventh day Adventist studies, it is clear the thinnest healthiest longest living populations eat little to no animal products..
Why deny reality?
He talks about fasting all the time. So that is calorie density.
He is telling the truth.
Just not how YOU want him to say it ???
If anyone is interested or needs more motivation: l was a fat, sick, very old-looking woman in Feb 2023 with a BMI of 34.5 (dangerously obese for my height), now I am getting IDd at bars again :D
I shed 76lbs in 6 months last year using fasting (between 24-76 hours most days of every week for the whole 6 months) and intense endurance exercise.
I went from an XL to an XS :)
All the obesity-related health-issues I was enduring had a total reversal. My skin shrank to the extent I am _constantly_ accused of surgery from randoms who see my transformation on the internet (it’s all documented). I also built muscle, fitness, and endurance from the bodyweight HIIT exercises and walking I was doing!
At almost 36 years old I am now getting ID’d again 😊
(Also I’m a mother of two teenagers! My belly looks like I haven’t had babies or ever been obese)
Anyway part of what I’m here to say is that most days I drank strong dark coffee (the plunger kind), with cream in during my fasts :o usually just one big cup with a splash of cream. So this confirms what Dr Fung has said in other videos that cream may not have a negative affect on autophagy ^_^ (though it may depend on the individual! I’m talking real cream from a cow, not artificial creamer)
Also it’s been a year since I shed the weight and have effortlessly maintained - my “set point” seems to be somewhere between 116-120lbs now??
I’m 5’2”, I eat OMAD as a lifestyle, and also do carnivore a lot of the time. I do running for exercise. I’d prefer walking but I’m often busy so I get the exercise done faster if I run.
Also I did all this in poverty!! People have told me I’m lying because I’d have to be rich for all the surgeries I’ve had 😅 But my front tooth is broken and badly coffee stained because I can’t even afford a dentist lol (not begging here, I don’t accept money or donations, I’m just trying to emphasise what’s possible even with no resources!!
Hopefully this can help give you hope and motivation if you see it :D
what a legend! thats bloody amazing! xx
Good for you…🙌 it can be done without any financial strain.
I did it and lost 90 lbs in 10 months.
No special foods or the gym. Everything was done at home:)
Huzzah!
Fasting saves money on food, vitamins and doctors ! Way to go.!!
Thank you for making these videos
and NOT charging for the info Dr. Fung!
Good reminder Dr. Fung. I got my fasting groove back. I have reestblished a 36 hour fast today. Today as I was feeling hunger I thought of you and reminded myself that this is just my ghrelin getting turned up.
Same here. Just restarted 36-42 hr fasts over the last month. Feels great to be back at it.
Hi Dr. Fung,
I followed your advice about intermittent fasting. I lost 15 pounds in 3 months. My A1C from 6.3 to 5.8. I appreciate your time and effort to make these videos on UA-cam ! Thank you for your help 🎉
👏🏾👏🏾👍🏾👍🏾
How many hours did you fast for?
you'll regain all your fat and then some by the end of the next year, I very much promise you!
@@Amaraticando not necessarily. For years I was in 207-210 lb range. Followed Dr.Fung intermittent fasting and ACV and have maintained my new weight of 180-183 for over 3 years. You can do it
@@Amaraticando not true
The great thing about fasting is it actually increases the metabolism when you do fasts 96h and under. It also regenerates organs like the thyroid at the end of the fast due to growth hormone generation. Hormons like testosterone slowly wane with age but in both men and women, growth hormone reduces by 2/3 as soon as we are adults and stays that way forever for most people. The many benefits of occasional extended fasting and lowering dietary carbs:
Your body recycles up to 1/3 of all immune cells in a 72h fast, rejuvenating your immune system. This helps with autoimmune disease, cancers and cytokine storm.
Reduces B cells by over half in a single fast, greatly reducing allergic and other autoimmune responses.
Fasting and low carb help with POTS, which is driven by high insulin and blood sugar.
Fasting reduces cortisol over time and improves your circadian rhythm.
Fibrosis aka scarring is reversed over time, including in the heart, lungs and clots.
Clotting and fibrin are inhibited, stopping any 'unusual' clots.
Fasting stimulates phagocytosis, the ingestion of proteins, pathogens and plaques by macrophages and other immune bodies. This will remove spikes quicker, whether natural or unnatural in origin!
Fasting restores NAD+, reduces NADH and increases nitric oxide release to open blood vessels.
Reflexes and short term memory are increased.
Fasts from 36-96 h increase metabolic rate due to norepinephrine release!.
Blood sugar and insulin are lowered when fasting, reducing inflammation and allowing the immune bodies to move freely through the body.
T cells are cruciall in fighting cancer, autoimmune disease and infection. With age, the thymus generally stops making them but fasting releases stem cells, which then can become new T cells. It also releases growth hormone, which regenerates the thymus!
When insulin is high, vit D stays locked in the blood cells but fasting quickly lowers it. Vitamin D plasma levels are increased as fasting improves metabolic health, and D in turn increases autophagy.
Fasting increases anti-aging Yamanaka factors and increases average telomere length in stem cell pools.
Fasting increases interferon, which shuts down the ability of viruses to replicate.
Clots and plaques are removed over time due to accelerated phagocytosis.
The hunger hormone ghrelin also lowers with extended fasting and rises from dieting.
Fasting does not reduce testosterone over time. Iraises it when the fast is broken by increasing lutenizing hormone. Fasting also increases insulin sensitivity, which helps with muscle building. And removes fat, which also increases estrogen in men.
Fasting activates autophagy (literally self eating). This recycles damaged proteins and foreign matter such as viruses.
Fasting can help with MS, Depression, BPD, Autism and seizures.
Weight loss from daily caloric restriction has 1/4 to 1/3 of the weight lost as lean tissue while many studies show fat loss from 36 h fasts without losing any lean tissue!
The obese will lose loose skin while fasting, but the frail will have increased growth hormone release, which helps to make more lean tissue and reduce frailness.
It increases mitochondrial function and repairs mtDNA. Mitochondrial function also has the added benefit of increasing your metabolism, fighting infection and cancer prevention!
24h of fasting reduces leptin levels by half! This reduces leptin resistance, which impairs immune function.
Over time fasting normalizes stomach acid levels and during the fast acid levels go down to allow for the healing of ulcers.
Fasting reduces pain and anxiety by stimulating the endocannabinoid system, just like the effect of CBD oil
Your brain prefers to burn ketones at a rate of around 2.5 to 1 when equally available to glucose. Except for brief periods of very intense exercise, your body mainly burns free fatty acids.
When not in ketosis, the brain can only burn glucose, which produces a great deal of damaging ROS the brain has to deal with.
Fasts of 36-96 will not affect short term female fertility or affect menstrual cycle. They also may increase long term fertility for some women.
Fasting releases BDNF and NGF in the blood, creating new nerve and brain cell growth. This helps a great deal with diseases like MS, peripheral neuropathy and Alzheimers.
Fasting stimulates apoptosis in senescent or genetically damaged cells, destroying them. Senescent cells are responsible for many of the effects of aging and are a root cause of the development of cancer.
Glycine and trimethylglycine (TMG) can also be useful supplements while fasting that won't break ketosis and have many benefits.
A fasting mimicking diet for 3-5 days in a row provides many of the same benefits as water fasting. FMD has about 200-800 calories, under 18 g of protein and zero net carbs.
What breaks a fast? Anything with protein or carbohydrates in it will break a fast but most teas and herbs are OK. Supplements and meds usually break ketosis directly or contain a filler that wil, or irritate the stomachl. Many meds are dangerous to take while fasting.
Exogenous ketones can aid with fasting, allowing some people with specific issues to fast in spite of them without worrying as much about hypoglycemia. They also help with dementia and many other issues even if you take them while not fasting!
Children, expecting or nursing women should not fast for periods longer than 16 hours. People with pancreatic tumors that excrete insulin or certain rare forms of hypoglycemia generally cannot fast at all or only with doctor supervision. T1 diabetics can also fast but it is more complicated and should be approached with caution as it could lead to ketoacidosis and done under doctor supervision. If you experience extreme symptoms of some kind, especially dizziness or tremors, then simply break the fast with a low carb meal.

Post menopausal, Intermittent faster here, now for 28 months. I lost 19% of my body weight in the first six months however my set point wanted me to weigh slightly more and I now accept that my body is happier at a slightly higher weight. I’m at goal and weigh about 16% less from the time I started intermittent fasting. I’m down three pants sizes and I take my body measurements once a month. Thank you for your channel Dr. Fung intermittent fasting actually is pretty easy to do. I think of it as a light switch, on or off, eating not eating.
What is it you do ? 16/8 ? 24, 36, 48, 72 Hrs ? Thanks.
@@MarinaLaroche Hi Marina, I started IF, intermittent fasting doing “OMAD”, one meal a day. I did that until I got to my goal weight which was lower than I am now. So after I got to my goal weight I switched to 2MAD, two meals a day. Some days I still do OMAD, just depends on how I feel that day. I try to not eat before noon which means I’ve fasted from roughly 15-18 hours from the previous day. I drink black coffee in the morning, that was hard for me because I always drank coffee with 1/2 & 1/2. Now as a treat I’ll drink my coffee with heavy whipping cream and it’s divine! I also drink a lot of plain seltzer water with lemon or lime in it and I did that from the beginning. Yesterday was July 4th and I gave myself license to eat all that I wanted. I met friends for breakfast at 8am and had a giant Mexican breakfast of chilaquiles, dinner was at 7pm. We ate bratwurst on buns with homemade coleslaw, french fries, raspberry sorbet with Trader Joe’s ginger snap cookies and wine before, during and after dinner. I hope this is helpful to you, you can do it Marina! By the way I just had a physical with tons of blood work, A1C…perfect, blood pressure…perfect, cholesterol…perfect.
@@hoovergrant Thank you for such a detailed reply ! I've been strict keto for years now. It's always great to hear of people's good results !
@@hoovergrant Reread your first post and see you're part of the Menopaused world too lol.
@@MarinaLaroche I don’t understand, reread my first post? I thought saying post menopausal stated that I am woman, born as, identify as.
Anyway, I know a number of people who have done and do keto. Personally it would be impossible for “me”, to repeat, for “me” to follow a keto diet.
I love meat but I’m also a very broad eater and could not imagine excluding categories of food or even an individual item of food. Maybe consider a “diet break” for a couple of weeks. I picked up that expression from UA-cam, trainer Mike Cola.
🎉 I get too excited when I get a notification of a new video of yours.
Same!!
Absolutely true.
Likewise
Thank you Dr. Fung. Your analogies are so helpful.
Any treatment for obesity that doesn't treat the body fat thermostat is doomed to fail over the long term.
Wow. You’re brilliant. That’s just what Dr Fung said. Amazing 😂
@@rollingstone3017 rude
Jason Fung is a breaker of thermostats with his fasting and keto advices.
@@shellyc8080 yeah, well, check out his other inane comments and get back with me on being “rude”.
Fact. Most of us are living proof.
2 things adjust the body thermostat aside from excersising. 1 intermittent fasting. 2 adjusting the kinds of foods you eat and ratios. This means ditching seeds oil, minimizing carbs as much as you need on a individual basis, upping protein. If that isn't enough, up fat intake with healthy fats like animal fats, butter, ghee, olive oil or alvacado oil as long as not heated, coconut oil, sesame oil. Nuts, seeds, alvacado, olives, cocoa nibs, cheese, eggs, fatty meats as well as lean meats, are all good fats to have. Focusing on mostly whole foods helps too. Adding in fermented foods helps reset things.
These are the best ways to reset metabolism. Not saying everyone has to even eat a ketogenic or carnivore diet though I did for almost 2 years. But some form of low carb, primarily whole foods, seed oil free, antiinflammatory diet does the trick. That can be keto, ketovore, carnivore, Paleo, Mediterranean, or any form of low carb you create individually. I'm doing my own version of low fodmap general low carb no real guidelines but below 100 g carbs a day, usually between 60-70 g total but under 50 g net currently. Some people do well on less, some on more. Hense my individual needs comments.
Could you share with me a couple of days average food plan please
Wait a minute, we’re not supposed to heat avocado oil?
@@rebeccanew9 heating olive oil and alvacado oil oxidizes it turning it into high omega 6 and high linoleic acid but the really nasty type found in hydrogenated and seed oils. Alvacado oil and olive oil have a low smoke point, and unless you know the exact temp you are cooking with and that's it's below that to prevent oxidation then you should not cook with it if it involves heat. Using in vinegrette, in sugar free cole slaw, drizzling over meat or veggies, using in low carb coffee and teas or in smoothies are all good ways you can use those though. It's not what yiu do but the how you do it that matters
@@helenchambers3291 I am currently doing at least 203 g protein mainly from animal sources but it varies daily. I've got a net carbs limit of 50g which puts total carbs most days between 60-70 g. Most of that comes from fruit and dairy and maybe some fresh veggies or fermented plant products. I have started doing things like a single slice of rye bread toasted and topped with sugar free jam or low carb pumpkin butter along side meat, eggs, and a chia pudding with protein powder or a pritirn smoothie with chia and home made yogurt whey.
Supper is mostly meat, some veggies mpdtky fresh and maybe some fruit and nuts or nut butter. I may throw in things like shiritake or kelp noodles or whatever. Sometimes my carbs come from things like spaghetti sauce or home made Tikka masala sauce. It really varies. Right now I'm focused more on pork, chicken, and fish/shellfish as primary protein with things like beef heart or beef kids mixed in and my main red meat option. Sometimes I do low carb fruit like berries, sometimes I opt for a very small amount of high carb fruit like banana or apple.
I kinda do a wide range of foods.
@@missyleonis avocado oil does not have a low smoke point.
Hi Dr Fung! Thanks for posting this video. Really important information for weight loss and maintaining weight loss.
I'm 61 and lost 160 lbs by finding and following your videos, interviews, lectures and books. It reversed ALL my health issues. I'm maintaining well but I found it challenging to learn how to maintain once I met my goal weight. Maybe a video about maintenance? I feel the best I ever have and I'm loving my fasting lifestyle! Thank you so much for all you do for us! 🙏😀💪
Do the intermittent fasting every day like 16/8
what type of fasting did you do to lose all those pounds? How often do you fast? I need to lose 50 pounds.
@@michaelr.maxwell9437 Hi! At first , I just gave up ALL refined carbs and sugars. And increased my natural ( saturated) fats. Then I ate LCHF keto ( low carb high fat) and OMAD ( one meal a day) then skipped a day entirely once a week. I still eat healthy " ketovore" leaning more towards meats, eggs, fermented veggies (kimchi/sauerkraut etc) and some nuts and seeds etc. Read Dr Fung's The Obesity Code. It will explain everything so well. You can watch my story on The Magic of Fasting UA-cam channel 😊. I also have just started my own channel you can link to from my name tag. Thanks again and be well 👍🙏💪

Can't wait to hear more about how to change our set weight. Great topic!
Whoah..amazing content. This explains a lot..i am grateful for this channel Dr. Fung!
Thank you for all your videos. I follow the intermitting fasting and i feel so much better with my weight loss. Your advise has probably extended my life.
Thank you for your informative videos. I fast 16/8 . To date I lost 25 pounds. I have another 10 pounds to go.
Back in 2018, I read The Obesity Code as I started my Keto journey. I have referred many people to it because of the information on body set weight. For those wondering the how to reset your body set weight, you should read Dr. Fung's book. He also talks about it on previous videos. I'll give you a hint. It involves intermittent fasting. 😊
Or you could watch the video
You are my favorite person. In the recent video, you said you made people fat and didn't know better, and now you know and are correcting your error and HELPING people. 💚 I love you! Thank you. The only doctor I trust.
Can’t wait to hear the HOW now !!!!
You’re the best teacher and a phenomenal doctor!
Dr. Fung makes everything understandable and I really enjoy his info. Gotta get the book The Obesity Code!!! Thank you.
Love these videos! Please post as much as you want!
Another great video from the GOAT Dr J Fung!
Great video Jason, thank you. 👍
I sort of knew rbis but not really understood it til this video. Thank you, explains a lot.
Many thanks for all your hard work Dr. Fung. I've learned alot and improved my health substantially since coming across your books and UA-cam channel.
Thank you for compiling such a comprehensive list of great fasting facts!
People can say whatever they want. I water fasted for 92 days and cured my stage four cancer. Not only that but I lost a ton of weight with no loose skin. Got off ALL my medication and look younger than I am by 20 years. It works. I was morbidly obese. I’m still fat but I’m not dying and continue to lose through OMAD and keto diet
@@jacktyleradams4430 Awesome!! Congratulations and best wishes for a long life 🙏🏻
Did you drink distilled water, tap, bottled? Thank you
Amazing! You should go on Dr. Chaffee's channel to share your story with a wider audience. There's many people suffering now who could benefit so much by knowing about you.
Or if not Dr. Chaffee, then Violet from Road To Health, or Kerry from HomesteadHow.

Good question
We’re all dying but I’m glad you’re not dying specially from cancer anymore.
Dr. Fung- will you please do a video on the impacts of fasting for certain lengths of time and how it impacts the metabolism. Ex. The impact of a 24-36 hour fast vs a 10-12 hour fast and how it impacts over time.
I will keep my eyes open for part 2
Sure look forward to learning how to reserve my fat thermostat. Thank you.
Thank you Dr. Fung! You saved my life
Great topic!!!
Thank you!
Thanks. Enjoyed that.
Dr. Fung, I am new to your work. I would ask that as you continue on this excellent topic, please make clear when you "adjust the thermasat" what does increasing/ deacreaing the thermostat mean? Is it increasing/ decreasing weight, respectively? Great job teasing this topic!
Thank you for these videos and helping people.
What I noticed about this topic of the thermostat is it reminds me of a concept about becomming comfortable in a certain body condition. So in your example about hormones where it involves the nervous system, it reminds me about how when your body physically doesn't have a cerain range of motion is that you gradually train/adjust your body top get used to that range of motion and that becomes your new normal ROM.
With that in mind, it seems like it is all about getting your body to be in a non-stressed state, physically and hormonally toward the condition you want your body to be in.

Awesome!
It would have been useful to go into more detail with regard to how to reduce your body's thermostat. I've lost a lot of weight, I read The Obesity Code but for others who haven't, going into some detail on that would have been beneficial.
There is a prior video by Dr Fung, "weight loss (controlling body set weight)" from couple of years ago.
That video has more of an explanation as to how to reduce your body's thermostat, for anyone wanting that information go watch that video. I can't provide a link to it but it's about 3 years old of years old from 2021 and you can find it under his channel.
That video has a link from Dr Fung to another video of his that helps with losing weight. It's listed in the first comment to that video. I hope this information is helpful for someone.
It still a pleasure to listen to Dr Fung 💙💙
I started with Dr. Fung at the beginning of Covid doing IF ,low carb and daily exercise. I also did longer fast of 3-7 days. Sixteen months later I had lost 100 pounds! I was just below my green zone marker and kept it off for a year and half. Then went to Europe for a month visiting family during the holiday. I got away from my routine of food, exercise and fasting. Gained 25 pounds. Came home and got right back to all the healthy stuff. Lost 7 pounds but that last 15 pounds has been stuck like glue! It’s been over a year and half without a budge. It’s so frustrating but I guess my body is very happy to be at this weight. I’m still healthy. My health numbers are good! But man, sometimes it’s maddening to do the same things I did to lose the 100 pounds but not to drop even a pound. I’m looking forward to his next video to see if I can shock my body back to my original goal weight. Haha
Your book “The Obesity Code” is changing my life!! I am so thankful to you & my best friend for making certain I read it.
Thanks, Dr. Fung! Please focus on the HOW next time :)
He has lots of other videos on the "how".
@@LuvlyDaze....it would be useful if they were linked then for people, like me, who are first timers listening to him..
@@amethystfeathers7324I agree with you…this is the first time I watched a video from him about fat thermostat and I have read his Complete guide to fasting book. I guess I’ll have to get his obesity code book too
Hi Jason . Please make a video on what you eat on an average day. You and Dr Berg have turned me from being chubby grumpy and miserable human into a happy fit thriving man. Cheers
Hi Dr. Fung. How do we change our internal thermostat? I need to lose 50 pounds. Will intermittent fasting help change the internal thermostat? I was thinking of doing a 3 day water fast and then immediately starting a 16:8 intermittent fasting schedule. Will this lower my internal thermostat?
Ok! VERY helpful
Thank you🌷🌷🌷
Thanks.
Great info
Thank you
When will your new clinic in Toronto open and is there a link you can share?
So can a One meal a day ketogenic diet, along with exercise can decrease the levels of the body fat thermostat? A lot of will power is required
Thank you
Brilliant ❤
Good video. Just a note for the editor, at the end youtube pops up an overlay for another video of the channel but it blocks his face. You might center the doctor during the outro part of the video so it's in the middle so we his face clearly.
Very interesting. I'm looking forrward to your follow up video about the specific hormones that affect one's body fat thermostat. Some years ago, I was excercising heavily, lots of cardio, spinning classes, etc. Hardly lost weight, and what I did lose I gained right back. I know now that what I was eating was just as critical as how much. I never had a fasting insulin test then, but I'm sure it would have been high as I was not only under a lot of stress, I was eating proabalby 3500-4000 calories a day of high carb foods.
Hello Dr. Fung. ❤
Thank you 🎉 ... Now I just need to know how to lower it 😅
Can u please tell us what the best artificial sweetener to use?
Good to know but you didn't tell us HOW to adjust it.
He did. Just google he has articles that talk about it. Plus its in his book.
@@TheRealCaptainMcFly What's the time stamp where he tells us?
Tack!
Great information!! What fast would you recommend for a menopausal woman ( 49 YO) with hypothyroidism?
Before I went into menopause I was always able to keep the weight off with IF … even with hypothyroidism!
But struggling to lose weight now I’m in menopause … what should I prioritise … my thyroid or menopause? Is it possible to lose weight with IF anymore?
So, how to you control the thermostat?
Question with GLP-1's. If you intermittent fast and eat low carb/keto while you are using them, are you still lowering your body thermostat?
Fasting is the ultimate tool for hormonal control for the body fat thermostat. Brilliant video, Dr. Fung!
I hope you can do a video on getting into ketosis. Some say 18 hours others say 2 days. Also how it varies individually. So more info regatding this would be nice.
It hit me in 2023. At some point, after great success with keto, I still gained weight again. Now I walk for 60 minutes a day with a weighted vest so that my body thinks I'm already 20kg heavier. Since then I've been less hungry and lost weight again. Unfortunately, I can't judge whether it's the more difficult sport or the more weight on the bones.
Hi Dr. I was wondering did melatonin will break the fast? Thank you so much for your time and help 🙏
I lost 160 pounds naturally through IF, low carb/ whole foods, exercise, stress management, sleep routine... unfortunately, I am slowly regaining weight at about a pound every 6-8 weeks staying strict to the protocol. It's been 3 years in maintenance and I am still slowly regaining (20lbs+) ... not lots of information out there. Approximately, how long does it take for the body to adjust?
If your calorie intake is the same now as it were during your weight-loss phase then your body has become more efficient so you need to adjust down the calories you eat, usually too much fat.
The thermostat is set by the unsaturated to saturated body fat ratio.
The more saturated your body fat is the less fat cells respond to insulin signaling, and thus the less fat they accumulate.
The key here is to make fat cells more insuline resistant (physiological not patological), while keeping the rest of the body insuline sensitive.
Dr. Fung, i must stay that your thumbnail game is getting strong. Mr. beast is taking notes...lol
I practiced, and it helps. You go to the bathroom and fart also
I don't need your arab money, I need the divorce and job
This makes sense! Need more info on how to adjust that thermostat.
So, how do we adjust the thermostat? Please advise
Hi Dr. Jason Fung. Thank for your advise i lost 11 kgs in 3 months. Maintaining daily green tea intakes and just eating fruits as part of my diet and at most eggs. After 11 kgs lost from total weight without exercise. I now found out that my weight does not reduce. I need to do some slow steep hill walk daily(500 meter) for a week in order to drop another 1 kg. It seems that the fasting works for the first 11 kgs but to loose more kgs you need to exercise and fasting does not work.
It does work. There are many videos on UA-cam showing continued progress for people. If you’re mainly going to live on fruit, you’re going to screw up your metabolism.
More fats and protein. You're not eating enough
I dont feel hungry actually. My body is used to it. Dr. Wiliam li mentioned about eating more seafood to loose weight. im eating seafood and protiens. Fats not really. Veg and fruits yes.
That's YOUR experience.
I have lost 3 stone (nearly 20 kg) in 4 mths just with carnivore and IF.
Try having one less piece of fruit a day.
I eat 3 pieces of fruit a day but I have to reduce it when I am trying to drop weight.
I add the fruit back when I get where I want.
How to do or should I do fasting if I have high Uric Asid or gout
Dr. Fung. Can you help me to understand the following?
I am a type two diabetic, working on managing my blood sugar through IF and reducing carbs (125 or less per day), and sugars (25 or less per day). We recently had a loss in our family and because I was so upset, I didn't eat more than 100 calories daily for about four days. On the fourth day, a friend used a glucose monitor to check my blood sugar - which read 200 - much higher than my previous read at 129. I was shocked! Can you please explain this phenomenon in a future video? Thanks!
Most people I know, including myself, blow that statistic about gaining one pound per year, to bits. When I gain weight, it isn’t a slow process at all and I certainly isn’t just one pound.
I seriously can gain 3-5 pounds if I eat a half pound bacon cheeseburger on a bun, whilst planning for it all day by eating "right". Now I eat a 4 oz bacon burger on the plate (no bun) - haven't had bread in 2 years. Did taste a bun a few weeks ago. It was weird and didn't taste at all like I remember it. Spit it out.
WHOLE FOODS FOR THE WIN!!
Yeah this average includes people who stay the same weight and people who lose weight. Tells you very nothing about individuals. A friend of mine gained 100 lbs during lockdown. Still it's true metabolism, hunger and energy change as you lose weight making it harder so what works to lose 10 lbs isn't necessarily still going to work to lose 50.
HOW do you adjust the thermostat???
have been trying to get an answer for this question. I have seen a lot of videos by the amazing Dr. Fung but I don't seem to get the answer. During prolong fasting such as 3-4 days, What Minerals or vitamins do you have to take? Or assuming that you're healthy with no medical conditions, you don't take anything? Have you guys seen this, have you guys seen him answer this question before?
I'd only take electrolytes (no sugar added, no extra fillers). Nothing else really necessary. The body will recycle everything, provided you have enough body fat. 😉✌️
Where's the best place to start with fasting... I can do 16/8 but my body fat( especially belly, inner thigh fat) stays at 33% ,disappointed. I am 59, post menopausal, I eat clean mostly, no alcohol, exercise of some sort daily. Had bloods done, shows cortisol and insulin are up...any good help I'd appreciate
@@helenchambers3291 Low carb diet, intermittent Fasting, good sleep, exercise and mindfulness all are needed to help you.
Check out videos from Megan Ramos who works with Dr.Fung. Minimum 36 hours up to occasional 96 hour fasts if you can work up to it. Once you are fat adapted during fasting it starts to feel like a super power ( at least to me. - Post menopausal & with extreme belly weight.) Need to drop the insulin long enough to get into ketosis and start to burn your own fat. Fasting really has helped me with visceral fat loss. Good luck and trust the process.
I will be here waiting for the next part
Will a Ketotic state reduce the set point?
How heritable is the body set weight?
Watch Peter Attia's interview with Stephen Guyenet to find out. (TLDR it could be as high as 75%. Compare with height which is 85% heritable.)
@billyhw5492 Yes!! I saw that & ❤ that one. Watch Huberman's interview w Dr. Zachary Knight gives similar percentages; says 80% genetic.
@@billyhw5492Yes! ❤ That one..Watch Huberman's interview w Dr Zach Knight. Gives the same percentages.
Did our genetics radically change in the past 100 years? Genetic nature nurture studies inadequately disentangle the genetic and environmental factors. They overestimate nature and this poor science is excused for politico economic reasons. The heritability parameter is widely misunderstood.
@@afnandridi9595 No. Genetics is actually the only real science in the field of obesity. identical twins raised in different environments have body weights that correlate at 95%. As Guyinet explains, it is the interplay between genes & the environment that have changed. For example, you cannot become obese if food is scarce. in abundance, that changes. Zach Knight estimates 50% of the population has the capacity. The science is still in its infancy however.
could you please do a video about lipedema treatment? it is very ugly and painful disease
An interesting discussion. Lowering the body fat thermostat using hormones like GLP1 explains why hormone mimicking substances like semaglutide (Ozempic, Wegovy) are so effective for weight loss. I’m wondering if losing weight slowly and staying on weight loss plateaus for extended periods may permanently reset the body fat thermostat lower?
I’ve lost 30 pounds on Ozempic over 8 months. I want to lose another 15 and am already thinking about maintenance and how to avoid a weight gain rebound. I’ve stayed on a low dosage (1. 0 mg or less) hoping to acclimate my body to anew weight set point and to minimize symptoms of gastric discomfort. I’ve paired this with dedicated strength training, cardio, Pilates and yoga. I’m feeling so much better and really want to sustain this loss. I’m also thinking of tapering the medication very slowly once I’ve achieved my weight loss goal and intermittently cycling semaglutide if I start to put the weight back on.
I’m interested in Dr Fung’s ideas about how to permanently reset the body fat thermostat after weight loss.
They're terrible for weight loss. You lose 50% muscle and once you come off you balloon up to being worse than before.
I haven't been able to find any evidence that losing slowly or staying on plateaus actually changes the set point. The only things that seem to treat the set point (not cure the problem) is A. bariatric sugery and B. these new medications. And if you were to undo the surgery or stop the medications the set point returns back to where it was. They don't even fully understand why the surgery and medications work. There are some plausible theories out there, but they don't really know for sure.
I lost 60 pounds in 9 months doing OMAD keto. And kept it off since 2018. I’m also 60 years old. You don’t need drugs you just need to fast and stay away from fruits and artificial sweeteners.
Let go🎉
Dr. Fung all good but you still didn't tell us HOW TO ADJUST BODY FAT THERMOSTAT ?
I need to know how to set my thermostat to like 150lbs LOL. Release the knowledge Dr. Fung 🙏🏾!!! Fasting has allowed me to shed weight and clean up my relationship with food like NOTHING ELSE!! I've been obese since I was a child. And to think it was in the bible the whole time!!!!
Nothing magical about fasting...it's JUST caloric restriction....and prbly not healthy long term.
How do you change it?
Intermittent fasting, unprocessed food. Food combinations - fat+protein, less carbs
@@juliantreidiii I think he’s going to cover how in his next video.
i need help i lost 5 kgs wid intermittent fasting i gain back 4 kgs how to sustain,,,,plz assist wanna loose 25kgs
Apologies in advance for nitpicking the analogy, but you can't move cold into a room; you can only remove heat. Just like you can't apply darkness to a room; you can only turn off the lights. This just rubs wrong people with an understanding of thermodynamics.
For anyone searching: This is not a video on HOW to recallibrate your set point
THAT is what I am after. 😢
@@javadivawithdog same😭
I'm a little under 180 pounds at 59. 25 years since diabetes diagnosis. I'm insulin dependent. I've never gone over 200 in my life. My Endocrinologist said my "ideal" weight is 145. He's a skinny guy from Pakistan. I'm not very tall so I know I'm overweight according to the BMI (like half the country) but when I tell others this they think I look "normal" and the doctor is being unrealistic. Is it worth it to try to override what your body's genetics thinks u should weigh? Or r u really just fighting mother nature and your body will not appreciate u starving it to go well below what it thinks it should weigh?
What happens to the excess fat you consume, since it doesn’t raise insulin to store it.?
I've watched a couple of your videos about IF and weight loss. There's something I'm missing: you just explained why we need to control the hormones (thermostat) which will then self regulate to reduce our weight like controlling our satiety and up our metabolism.
BUT on the other hand, you often say, example in the 5 IF mistakes video, that in our feeding window, we must not overeat, because at the end of the day, we need to still be in a Caloric deficit... well, if we overeat, maybe it's because of our hunger? why don't we feel full after eating normally if we supposedly dialed down the thermostat? what I have found with my experience is we have to "push through" the hunger and learn that hunger isn't painful but enjoyable and I believe that's a much harder pill to swallow than "eat in small window and your hunger will go away because you changed the thermostat"
if anybody wants to comment or Explain, please do
How do RESET the thermostat ???
It's difficult to know how to recognise what's going on in order to know how to "turn up the thermostat".
I've been IF and carnivore since 25th February 2024 (just over 4 mths). In that time I have cured my T2 diabetes and also lost 3 stone (nearly 20kg) in weight.
Except just this last week I have actually put on a pound or 2.
I have noticed that I have been feeling more tired and hungrier this week and have been eating sausages where previously they had been excluded from my diet.
However, I have also been rather stressed due to the approaching general election (I have been involved).
Also when I listed what my typical food intake is on another video, someone commented that I was only eating approximately 1700 calories (I don't count calories so had never figured that out).
So am I not eating enough or has the introduction of sausages been a negative or is it just stress and things will settle back down now the election is over?
Hormones are SO confusing.
Edit to add that it was Jason Fung who I first found to help with my fatty liver and from there started IF. So thanks Dr. F!
That was a really awesome explanation, thank you!
