Fasting and Metabolic Rate (How to avoid Starvation Mode) | Jason Fung
Вставка
- Опубліковано 12 чер 2024
- Metabolic rate is how much energy (calories) your body uses in a day for normal function. Calorie restricted diets lower metabolic rate, and this limits weight loss, and is often called starvation mode. Dr. Jason Fung explains why fasting does not lower metabolic rate thus allowing you to avoid the dreaded starvation mode that leads to weight loss plateau. Check out my blog at / drjasonfung

Even if I eat just 1000 calories everyday on a very low carb/insulin diet my metabolism wont slow down? I simply am not able to fill more than 1200 healthy calories in 2 meals. Thank you for all that you do.
I need your help
What if your bodyfat is already low BEFORE the fast. I have done two separate 5 day fasts, in the first one, I was 20 lbs overweight but in the second I was maybe 3 lbs overweight. In the first fast I lost 8 lbs but in the second, I lost NO weight. Is it possible I was in starvation mode during the second fast?
@@marciabernard615 my help??
Dr Fung do you do virtual consultations?
I'm so humbled and grateful that you featured me in this week's video. You have changed my life! Thank you for all you do to educate us on intermittent fasting!
You look so healthy & beautiful Megan! Awesome!👍😁
You had some great tips to add to Dr. Fung's talk. What you are doing really makes a difference.
Thank you both! Your words mean so much to me 💜
Hi Megan you are an encouraging example to us !!!! Congratulations for your healthy life choices, beautiful kiddo 👶
You look amazing and keep it up, Megan...!!! Way to go...!!
This man alone changed my life for the better.
❤❤❤❤❤❤
Same here!
Yup
You also changed your own life though, because you took the first steps and were ready to change.
Same 😉✨
Dr Fung restores respect to the human body when he says, "the body is not stupid." Thanks Dr Fung.
He is a sort of God-send. Revealing the power hidden from us for millennia
Your welcome kid
I don't need social media, groups, or other people to fast but I love to watch videos about fasting to encourage my decision to do it.
Dr Fung watching you read your books I have lost 40 pounds. I refused Metformin as a type 2 diabetic even shocked my GP, she said no patient of hers ever done that.Thank you so very much.
Wow Great Job Kathy!
@@drjasonfung dok can I do fasting im chronic hepatitis b px
@@drjasonfung what about someone taking 5 meds? My husband says he has to take them with food or he gets nauseous.
@@victorguani8799 Of course. Humans have always HAD to fast throughout history, it's a normal thing to do.
@@KarlDag Do you have a medical degree? Fasting has been normal throughout all of history, but people also died a lot back then too. A healthy person can usually always fast, but certain diseases/treatments for said diseases may not be compatible. This could be a potentially reckless statement to make.
I'm doing rolling 72's and so happy to hear my metabolism isn't going to decrease
I found that fasting goals without an end date really did help. I always hear that, "it's a marathon not a sprint" and that is SO TRUE. To put that into practice, I regularly reminded myself of how long it took to GAIN the weight, it should take at least that long (or longer!) to lose it. THat really helped keep me on track. I lost 55 pounds and have been able to keep it off with IF.
Thank you for this statement because I was becoming impatient with the weight loss. I have hypothyroid though. I started OMAD since February 1
I wouldn't say it needs to take as long, but it doesn't have to happen instantly either.
Thank you, you are absolutely right!
Wow that’s incredible progress! Good for you!
Been fasting for 60 hrs now. Going till 72. Thanks for your support. Yes it is lonely road, and we do need cheerleaders. On and off I stumble down from the wagon, but hop right back. No procastrination no cortisol.
Yay me too 64 hours still going . I want to try 7 days

@@eghobebe9733 that’s great probably good enough to get some good health benefits and just experience jtb
@@eghobebe9733 did you have sleep problems during this fast I did when I did 2 or 3 days
whenever i feel to quit , I started watch video about knowledge . not motivation videos.. motivation only for temporary.
I reversed my diabetes 10 years ago by changing my lifestyle...eating healthy and staying active everyday. I started doing 24 hour fasts about a year ago...as I age, I don’t feel the need to eat everyday, my body doesn’t crave food at all. I usually fast 48 hours, have a day of eating, and resume again. I also don’t let it consume my life, if a friend invites me for lunch, I’m there! I just start all over when done. Lol! I’ve maintained my weight, my A1C stays at 5.5 (it was 12.8 ten years ago!) and I have so much energy and feel great, even through rotator cuff surgery. I believe that’s why I healed so quickly. I’ll be 60 in 2 years and looking forward to it! Fasting keeps me young!😉 and lastly, my doctor was fantastic when I was initially diagnosed. He believed in me and gave me a chance to reversed this on my own. He referred me to a registered dietitian and I educated myself. It can be done. Thank you, Dr Fung...I continue to learn so much with your videos! Thank you for all you do 😎
Thanks for sharing, and to Dr Fung for demystifying! I'm happy to hear your a1c is 5.5. That is my goal; I'm at 6.5 now. To your good health!
That's inspiring. Thanks for sharing!
I told my doctor that I was going on a water fast for 2 weeks to combat my high blood pressure. She pretty much flipped out told me I could die and that meds was the only way I could control my problems. I told her I was doing it anyway. And left
I fasted 2 weeks. Blood pressure normal, blood sugar normal ect.
My doctor didnt say much anything about me being better she seemed stoned faced. After a couple years she left practice and I was given a new doctor. Have yet to meet that doctor.
This is my goal, to be so comfort with fasting that I go days without eating. So far I’m doing Omad and I feel fantastic. I’m always amazed at the effect fasting has on my emotional state. It’s like depression and anxiety just lift away and they’re replaced with mental clarity. I even feel more spiritual while fasting. Glad you’re in great health - love and light 🙏🏼💕✨
@@marmararraj76 Best wishes on your journey to great health! You can achieve it. Trust your instincts, our bodies know what to do. OMAD is a great, I like to mix it up a bit and do OMAD myself. And it is a very personal, spiritual journey. I can honestly say that my fasting lifestyle has changed my overall attitude and outlook on life. 😉😎
My fiance and I started low carb alternate day fasting for Lent (we started the Sunday before). I've lost 8 pounds, and my sugar has gone from 225 to 113 :) The first full-day fast was miserable. I was nauseated, shaky, weak, and vomited most of my water. The next fast day was unbelievable! I felt energized and clear-headed! I couldn't believe the difference. I love the feeling of an empty gut.
The quick effect on glucose levels is still amazing me everyday!
I dropped 45 pounds (and I ain’t picking it back up! Lol) over the course of a year using the 16:8 strategy. I never gave myself a timeframe, just a weight loss goal. I still have 20 pounds to go. I just stumbled across Dr. Fung’s videos a little while ago - it’s nice to know that I’ve been on the right track!
That is wonderful! You should be proud of yourself! Question: Did you have any plateaus and did you switch up the 16:8 at all?
Congrats, you are so inspiring! Cud you help me with a question? Even if I eat just 1000 calories while fasting my metabolism wont slow down? I simply am not able to fill more than 1000-1500 healthy calories in 2 meals in a 18-6 setup. (im a vegan). Did you not experience metabolism slowdown? And how much exercise did u put in? Thank you.
@@gothicqui on rare occasions, I did the 20:4 and a couple of times I did a full 24 hours, eating only dinner afterward, then right back to the 16:8.
Woo-hoo. Same. Just started 16:8 last week, and lost a bit overc3 lbs, with 20 to go. I was finding that I was eating in about an 8 hr window, and couldn't eat any more because I was making myself sick with the bad carbs. Once I heard dr. Fung explain the science, I started.
I already fell off a couple of days ago, only with my diet, not the hours...and was pleased that my sugar stayed low. I started over the next day, and looking forward to weighing next week.
So glad for your success!
@@Jens0215 where you eating a low-carb diet?
This man's content is some of the best out there. Everyone who is overweight needs to be introduced to your world Dr. Fung!
Probably because he “wrote the book” on weight loss & fasting😆
I’m thankful for this info now, but dang where was he 40 years ago!
Thank you Dr. Fung. I was diagnosed with T2 diabetes not long ago and my doctor made me take metformin. I learned about you and stopped my medication after a week of taking it. I have been doing IF and low sugar/carb diet and my fasting blood sugar is now between 90-112 in less than a month. Even after a meal it doesn’t spike. I’ve lost weight and I feel so much better! I bought 3 of your books in kindle and also hard copies to share with my husband who has been obese and always had a hard time losing weight despite trying all sorts of diets. He’s now fasting and doing the same diet with me.
how much weight have you guys lost?
I have a friend who did a 40 day water fast and her BMR improved rather than slowed down
My husband is no longer a diabetic thanks to you. Thank you very much Dr Fung.
Can u tell what he did plz... my mom is very sick she cant eat anything losing lots of weight because of the metformin 200 a day. She has no taste of anything... i cant do anything for her she is slim... is there anything that i should give her😥😢
@@happykhanusablog9999 watch Dr Fung’s videos and even The Diet Dr’s videos.
I give thanks to you, for i am fearfully and wonderfully made. Psalms 39:14
I’ve lost more weight or all the weight by fasting. Than working out! Thank you
👏 ❤ 😊
I've been doing IF for one month and I no longer have the urge to eat constantly nor I have cravings! I will be doing this for life now. It was very hard in the beginning but I just kept busy at work .
I have such a sweet tooth! Like a 3 year old 😶😏🤪but IF and a modified intake of non processed whole foods has almost totally eliminated the cravings. I would have NEVER thought that I could pass up candy, chocolate, ice cream etc but it has happened!
My 96 hour fast has ME SO energized!
I sleep like a satisfied infant - through the night - without even getting up to pee!
30 pounds with intermittent fasting, occasionally throwing in a several day fast to hit autophagy, keeps my body moving forward to my goal ! It's a shame my doctor is a dweeb 😆 lol
I have 4 hours left on my first 96 hour fast. I feel mostly how you describe. I found that nighttime before bed I would feel super hungry. And I would just watch mukbang videos on UA-cam but overall this was relatively easy!
Did you take electrolytes?
I always knew that starvation mode talk was bullshit. People think about the body like it is a simple system
A while back that mummified cadaver display was in VT, went to see it, there is nothing simple about human anatomy. It is amazingly complex.
@@michaeltherrien6006 because God made it
The problem with calorie restricted diets, in many cases, is that they don't allow the insulin levels to come down enough for the body to access the fat reserves. They (referring to the people on the calorie restricted diet) are burning more calories than they are consuming, but they still don't have access to the stored energy, so something has to give. Thus the metabolic rate ends up being reduced. The key point continues to be bringing down chronically high insulin levels so that the body can access its fat reserves, and until the insulin comes down, the body will not go into a catabolic state, and no significant amounts of body fat will be consumed.
Your comment is highly underrated. So perfectly explained and not too long. Keep shouting it.
the good doctor seriously looks younger every week
You are the best inspiration on u -tube, thank you so much! Lost over 55 lbs through intermittent fasting, eliminating sugar and refined carbohydrates and seed oil! Walking 55 kilometres a week or more not bad for a lady approaching her 69th birthday! I move like Jagger, lol! Never give up, we all have set backs, especially during tough times! Your advice makes so so much sense! Everyone spread the word and subscribe!
At age 63, you just gave me the inspiration I need! I cut out carbs and all sugar except 1 teaspoon a day in my coffee (and will be giving that up within the week). I've been doing keto and OMAD for 2 weeks and have only lost 3 pounds but have begun a 72 hour water fast in hopes of getting into autophagy and ramping things up a bit. I think I'm fighting a fatty liver as well as a slow metabolism from only eating OMAD for years but eating ALL the wrong "foods" (LOVE potatoes and fresh baked bread :O
I started reading your book and watching all of your videos in Sept 2018. From Sept 2018 to Feb 2019 I lost 70lbs. I fasted no more than 3 days at a time and never on the weekends. Why? because it's easier to fast when your day is busy. I also found it easier to keep fasting to myself because people who don't understand fasting will express negative views about it. I have had 1 set back in 2020 due to Covid and my workload. I gained 20lbs but have since lost it. Thank you for your knowledge.
Fasting make me reborn again am living my best life at 38 thanks so much for these fact# an health well being DR fung😇🥰
I just did my first 24 hr. I am blown away with how I felt the following 24 hrs. Mental clarity and energy through the roof!! I will be doing at least one 24hr fast every week. Not for weight loss, but for the other benefits. Outstanding youtube video.
How has your weight loss gone?
I been fasting like this for a long time lost a 150 ponds I am glad to now what I was doing was right Dr. Noun
I fast during the month of Ramadan from sun rise to sun set, it is hard the 1st two days then you get used to it and donot feel hungry. it is good for health and a good way to lose wait if I try to keep away from Ramadan desserts
Hell was never made you for you , you were never supposed to go to hell he wanted you to live with him in heaven always from the very beginning he had a plan to make it right this time to make a way for you to come back home to him , thats why in John 3:16 "for God so loved the world that he gave his only begotten son that who so ever believed in him shall not perish but have everlasting life".
@@apologeticministry Stop it! You should be apologetic, for your disrespect. Keep your religion to yourself and your deluded, childlike ideas of hell. Stop projecting. Stop being so arrogant that your made up storybook is better than other religions' made up storybooks.
Megan looks fabulous. Great job. I wish more people would start using this technique to lose weight. Most people think that fasting is unhealthy, and for people with eating disorders. So sad.
Dr. Fung, I am so grateful for you! I read The Obesity Code and watched your lectures. I’m down 25 pounds now and counting! For the first time in my life I don’t feel like I have a food addiction any more. Thanks for all you do!
I've been fasting 96 hours since May 2020 Starting at 6PM on Monday and Ending 6PM of Friday. Low Carbing through the weekend
Awesome!
Wow! I want to do that too! You’ve inspired me ☺️
Do you take electrolytes supplement during fasting?
@@lilizhang463 I use a bit of salt and I use Epsom Salt baths to help with Magnesium, I use zinc 50mg, D3 10k, C 2k, and lysine 2k mainly for immunity. I got asymptomatic covid and kept to the regiment. Didn't feel a thing. I eat high amounts of dark green leafy during the weekend. I do not do additional nutritional fat for the sake of ingesting fat. I get enough in red meat and dairy on the weekends.
Dr. Fung, Dr, Ywes and Dr Berg have been massive helps in teaching this 56 year old things I should have understood years ago. I have never taken and illicit drug or ever drank alcohol but just this year realized how I used food to manage stress causing a life of addiction. They have been so helpful in understanding the science and the psychology that has broken me free. I do not live on a diet. I am living a lifestyle that will moderate with my body's transformation but I will never go back to living a slave to my emotional cravings.
ever since i started fasting I've lost nothing but fat compared to when I was decreasing my calorie intake, yes I did lose weight from calorie restriction but I didn't look healthy at all or feel good . fasting is a miracle
But in reality...fasting is exactly that. Calorie restriction. The longer you go without intake of calories, the less you consume overall in any given tome frame, right?
@@gypsygirl9 Yeah in theory, but it's not that simple. For example if I wanna lose 2,5 lbs a week I have to eat ~1700 kcal a day. Spreading it out to 4 or 5 meals makes it almost impossible to go through a day for me. I'll be hangry all the time. Instead when I apply fasting, I go to work on an empty stomache, I usually don't get hungry at all, because I'm occupied with work. I eat a big meal at 12:30 ~800 kcal and then I go until evening and eat another big meal at 6:30 and I fast until the next day(18:6) that makes it alot easier to apply a calorie deficit. Of course it's all from my personal experience and it's not scientifc, just anecdote.
Simple calorie counting + eating at random times doesn't work for me.(needs a lot more will power)
There's something going on hormonally that I can't explain but I feel it.
@@gypsygirl9 i eat whatever i want during my 2 hour eating period. I eat till im full and I don't feel hungry until tomorrow. I dont count calories . when I wasn't fasting and doing calorie restriction I always felt hungry and I didn't feel so good but with fasting i feel really good
@@gypsygirl9 Yes, and you can retain more muscle mass compared to fasting as you can maintain higher average protein intake, and that will help you after the weight loss you've planed. ;)
@@gypsygirl9 This is exactly correct - in all these types of "diets" it is just framed differently so it becomes the new best approach. It will work and for some people is the best way of eating but not everyone. People will argue but it is simply about a caloric balance that determines weight (gain or loss) and of course other factors play a role in how efficient this process works in our body.
You are changing my life, already losing. I started on a low calorie diet on January 4th and switched to the intermittent fasting not more than 2 weeks ago and here I am. I AM LOSING THIS HORRIBLE FAT!!! Thank you so much!!
This may or may not help you but try not to think of it as "horrible fat ". Be kind to yourself and think of it as stored energy and you're simply deciding to use up that stored energy 🙂
Great job!
How has your weight loss gone?
Fasting is a miracle of any sickness thanks 🙏
I am totally amazed! Thank you Dr. Fung, Through a water fast over a very short period of time I lost over 15 pounds, something I tried to do since 1995 but couldn’t. The only advice I got was to eat less. I was given a recent diagnosis 2/2021 of diabetes. Fasting will end this forever.
I have been following Dr. Fung talks since last year, with my buddy recommendation. After understanding his theories, I was able to loose my weights easily. After my success in losing my weight, my other buddies followed and managed to loose their weight too, without feeling much difficulties. Thank you, Dr. Fung, this method is very effective, the best of all, it is FREE!
Yes, the _understanding_ part is so important. That makes the execution easier since it is not that intuitive.
"Our Bodies just aren't that stupid"!!!!!
Thank you
I started watching your video for since last year. I started fasting around October and my weight at that time was 240lbs. Now April 2021, I dropped down to 198! I combined fasting with low impact workout. I eat one meal a day Monday to Friday, then I do 16-8 on weekdays. Once a month, I do 48 hours fasting. It truly changed my life. Now, I don't feel guilty eating a slice of cake every now and then and wasn't as worried as before when my gain some water weight. Thank you!
This fear is removed.. I am on 20 :4 diet.. thank you dr Fang
Im doing the same! Love it!
Excellent information and reference Jason, I'd never stop fasting... I love the surge I have!
One of your best videos yet, Dr. Fung. Thank you for your work.

Thank you for being so encouraging!! Listening to your videos often help me get through rough moments during fasting.

You are my hero! Keep up the good work! I thank God for you!
Thanks Jason
Your info has helped me drop 15lbs in just a little time. Doing a high fat low carb diet too. Also doing omad through the week.
Thank you. I have previously been a bit confused on this particular topic. Thank you for the info Dr.
Thank you Dr. Fung, and God Bless you and your family!
Thank you for sharing the stories.
Dark coffee on a small cup & start moving. Don't eat till after noon. Keep busy (do small chores, exercise, walk, anything that keeps your blood flow moving). In US, we have a problem of excess & this is why fasting should work.
Thanks jillian michaels. Too bad all your clients gained the weight back and then some.
You're actually better off eating in the morning and not eating after noon. You eat less since you're less hungry and you get more energy throughout the day, which can help you burn more calories.
I love watching all of your videos. You are helping so many lives!! God Bless you!
You are the best ,truly ! Thank you so much ,we love you ❤️
So thankful to have found this channel Thank you Dr. Fung
Watching you Doc Jason Fung thanks for your for the extension of my life from the Phils.
Thank you dr Fung! Regarding the "caveman metabolism": I notice that I like working out while fasting. One would expect that in "starvation mode" you don't have any pleasure sweating. The opposite is true: working out allows you to fight the hunger feeling and you also get very good performance. I think it's correlated with the evolution reasoning you mention: modern workout is the equivalent of hunting, you need to be good at it when fasted.
God bless you, Dr. Fung!
Thank you Dr Fung and Megan!
Thank you for your no nonsense way of explaining this ! It makes it so easy to share so people can really get it !
❤️ you have helped changed my life ...!

This is an excellent video - short but crystal-clear explanations given throughout. Compelling. Thanks to you sharing your knowledge I've been able to embrace intermittent fasting as part of daily life (I've been doing it for several months). I will always be grateful to you - thanks very much from a 72 year-old dedicated-intermittent faster.
Thanks for all of your videos
Gratitude for sharing your knowledge to us and it’s easy to understand
To add to Dr. Fong's statement, "It's not a race but a marathon". As you go through your journey of a low carb/fasting lifestyle, you'll find that you may platto. This is where periodic extended fasts can help. I also think these plattos can possibly be the body making use of the extra skin. The scale may not be moving much but you might notice your shape looking more cut and less wrinkles.
This is helpful, but how do you know if it's a plateau, or it's not working (like if the plateau has lasted a while ... are you still on a plateau, or is it time to switch things up?)
@@nicoles5569 The body always adapts because it's a survival mechanism so you should always change it up. Everyday I do an 8/16 or 6/18 by just skipping breakfast. I'll randomly skip lunch and do an OMAD and sometimes I'll fast over the weekend for a 48 hour fast. So keep changing it up and use extended fasts to help break through the platto. Perhaps pull back more on carbs and/or protein. Everyone's body is different so experiment to see what works for you. My wife's body has been extra stubborn so she skips two days a week (Monday & Thursday) to help keep her progress going. Also, be sure to get some exercise. By exercise I mean take a leisure walk or bike ride. If you're job requires you to sit for long periods of time, get up and walk around a bit through out the day. Use the farthest bathroom for your bathroom breaks, etc.
Very well said. Thanks
He is wrong. It is a race. It has already been proven via the Matador study that your body starts reducing its metabolic rate as soon as 2 weeks after realizing your calories have reduced. Thus the key to losing is losing quickly and then taking a break.
@@CelineNoyce the MATADOR diet is basically saying the same thing. It only allows you calorie deprivation for a short time (2 weeks) then back to normal calories for 2 weeks. Then repeat. This is the same long term strategy as Fasting then re-feeding with no calorie deprivation. Weight loss is always long term unless you only have a couple pounds to lose.
Thank You Jason Fung, you’re a miracle worker! Thanks to your videos I have done intermittent fasting for 1 month and have lost 25lbs. I still have 50 more to go,
Great info, thank you Dr. Fung!
Thank you so much Dr Fung.
Thank you for your intelligence and ability to explain the body processes in a clear and easy to understand way. I started intermittent fasting a year and a half ago and it’s changed my life! ❤️
Great video Dr Fung. That explanation about the Noradrenaline is key to me understanding why I wasn't doing well with calorie restriction, as I've watched you explain this before. Now fasting 23:1 since Oct '20 it's going well, you've changed my adult life. Never felt better; combining this with very low carb intake. Thanks so much.
Dr. Fung thank you for sharing the articles you mention. I link to your videos on my Facebook page and website.

Thank you for answering my #1 question about fasting!
Thank you for saving my life.
Thanks Dr Jason Fung who helped me a lot God bless you !
I did a 21 day water fast in Jan and I’m on day 9 of a 14 day fast this month. I can literally feel that burst of energy. It’s normally day 4 for me.
That's incredible! Did you shed a lot of pounds?
I am on day 4 now. I also wanna do 21. how much weight did you lose?😃
@@Swiss_Girl is it only water you will consume ?
I'm on day-33 of a fast however I use bile salts, no calorie electrolytes, and sometimes I take vitamin B1 to help me sleep.
I find fasting easy with this protocol however, I can't imagine a water fast...
Do u take any electrolytes
Thanks for these videos. Watch almost every day for reassurance of the science that supports intermittent fasting as a safe and valuable way to lose weight. Down 28 pounds, in three months, on my way to a goal of 60. Loving the way of life and result so far. But, the information is invaluable.
Thank you for the tips. Very helpful.
Thank you Dr. J. Fung!
I'm excited to start my IF journey to health. No time like the present. Thank you for all your amazing videos and information.
So grateful that we have Dr.Jason Fung it’s really helping me.
Thank you for sharing. Thank you for helping others.
Thank God I found this video today is my first day on a 2 days detox to start my journey
Thank you for clarifying our metabolism and fasting. I always wondered was I slowing my metabolism and stopping my self from losing. It’s when we get into starvation mode when we see weight loss stalls. Thank you very much for educating us.
A great example of how, when and where our bodies switch from one energy source is found in bears. They hibernate in winter when food is scarce and their body fat keeps them alive. I don’t see them hitting the gym either!
And humans actually get into ketosis much more easily than bears. We are better fasters than bears are!
If I saw a bear in the gym, I'm never going back lol
