Fasting, Muscle Loss and Protein Needs – the facts | Jason Fung
💪 Does fasting burn muscle? Absolutely not! This video explains why fasting doesn’t lead to muscle loss and dives into how the body uses energy from stored fat and glucose rather than breaking down muscle. Dr. Jason Fung discusses the science behind muscle preservation during fasting, the role of protein, and how muscle growth is actually tied to exercise, not just protein intake.
Topics Covered:
How fasting impacts muscle mass
Why protein intake is important but often overestimated
Understanding muscle strength and energy during fasting
Studies on fasting and muscle strength improvement 🧪
Key Takeaways:
1️⃣ Fasting primarily uses fat and glucose, sparing muscle tissue
2️⃣ Muscular strength remains stable, even during long fasts
3️⃣ Overeating protein doesn’t necessarily build more muscle; exercise is essential 💪
4️⃣ Fasting may even improve heart muscle health after a heart attack ❤️
Watch to learn more about the fascinating link between fasting and muscle health. Don’t let myths hold you back from the benefits of fasting! 🌟

Jason, thank you so much. Following your advice has dramatically changed my life for the better. By every metric imaginable, I am healthier now than I have been since my mid 20’s. I have lost 100 lbs, metabolically resilient and have tons of energy. Keep doing what you’re doing.
Awesome! You must feel so much better.😊
@@AzaleaBeesure do. I will never go back to eating 3 times a day
@johnreynolds1912 Yup. For me, I eat 0-3 times a day period. The three times is rare.
Hi John – are you on the low carb / keto diet ?
Thank you for doing the research for us, and delivering it in layman’s terms so that we can all benefit. Useful and fabulous as always.😊❤😊
Finally an expert answers the age old question of how much protein do you actually need to prevent muscle loss. Thank You Dr Fung!
I agree 👍”
Yes
@@Poppy_love59 I’m sure many experts have a different opinion. A better question is, will extra protein do us any harm
Dr Fung is a HERO
He really is. . . . . if only more people knew who he is and how smart and full of vital information he has.
Plz more on fasting and muscle loss cause its the only topic that sets me back. thansk jason
I just found Dr Fung online and things are finally making sense to me. Thank you!
I recommend three of his books, The Obesity Code, The Diabetes Code, and The Cancer Code.. and I that order.
This is SO helpful. I remember your blog post from several years ago addressing these protein needs. I’m 62 and receive a lot of information about how I need to up my protein. Whenever I go over 60 g per day – my Blood Glucose rises dramatically this next morning. I appreciate you sticking to your stance and stating it again – I have regained so much health, thanks to you and Megan.
This is my 4th year without any diabetic medication due to Jason’s advice. Intermittent Fasting.
I can’t believe that I did a 5-day fast 😳
@@jamescalifornia2964 Non in fact it is my 4th year. So if you need any help plz contact me.
great, and … what diet do u do, are u low carb / keto ?
That’s great. I started fasting about 30 years ago. Today (over 70) have no medical conditions, BMI 22 and don’t wear glasses. My identical twin brother had never fasted and passed away with cancer 8 years ago.
@@Franky2A3 – so do u fast just for each day, or more than a day ? and what r your meals like ? are u low carb ?
Who else loves Dr Fung’s frank and very blunt way of explaining things? Very refreshing.
I kind of miss him saying “that would be craaaazy” in his early videos. 😀
He certainly does the research 👍
every german
I love when he says, “It’s like, ‘Duh!'” 😂😂😂
I do too!! 👍😉👏
High Protein is one of the Biggest Myths of our Times ! Thnx Dr.Fung for confirming that too !
Sir sorry I want ask…if I do omad….one meal a day eat 30/40gram protien a day enuf?
Dr. Fung should be part of MAHA(Make America Healthy Again) team
doubt he wants to be part of a team ready to get rid of all immigrants legal or not
He is a Canadian not American
Why would an intelligent man like Dr. Fung get involved with the MAHA? He’s not ignorant.
Lighten up people he is talking about health. 🙄
Trump and Musk should have him on America health board
A much needed topic to be clearly explained. No one need to doubt it as it’s from a medical expert and that too explained with proof… He is just amazing🙏🙏
Thank you! Finally someone who gets it!!! I’m less hungry day to today with intermittent fasting.
Everyone is talking about the protein now! I gave in… struggling to lose weight and build muscle, working out every day. Im going back to intermittent fasting and low carb, which worked best for me. Thank you, Dr Fung!
Hi zhanna – how many hrs do u fast ? and do u eat 2MAD ? do u eat veg ? fruit ? grains ? ty
@Amanda_downunder I feel my best physically and mentally eating 2 meals a day within 6 hour window. You can have a small snack in between if you want, but after a while, you don’t need it. Veggies , protein, berries, some other fruit on occasion, good fats.. A big salad for one meal and cooked veggies wirh protein for the second meal . I also get low carb tortillas if I want a wrap, which help me stick to the plan, or overnight protein oats. Definitely cut out sugar.
Hope this helps .
@@zhanna5827 – yes, thank you; it is helpful. I have lack of discipline. “good fats” – is that avocado, olive oil, nuts ? for protein, u mean fish, poultry, red meat ? ty
@Amanda_downunder pretty much, but not limited to. With only 2 meals a day, we can make those plates look and taste good. Besides Dr Fung, I learned a lot from Sten Ekberg (he’s amazing at explaining things), book and podcasts by
Gin Stephens, Ben Bikman, and others. Keep it simple. Maybe,start with Becky Gillaspys 0123 strategy, which stands for 0 sugar, 1 big salad a day, 2 cups of cooked veggies, and stop eating 3 hours before bed. See what plan works best for you
Check Dr Jack Kruse book and his easy protocols, cheap book.
You’ll loose all the weight you want
Timing is perfect! I had great success in 2019 fasting and being consistent in a the gym. I felt amazing, was strong and healthy. Pandemic brought back some poor lifestyle habits, I have gained weight, lost muscle. I have been searching for ways to get back into a sustainable lifestyle again, and got caught up in the guru’s talking about not fasting, I have been forcing myself to eat multiple meals with tons of protein. Well, I gain more weight, and the changes in the gym are not better or worst than with fasting. So, I am happily back to a fasting routine and moderate protein, as I can maintain that and if fits my lifestyle!
Thank you so much for clarifying this Dr Fung. My heart specialist told me to stop fasting as it would ruin my heart 🥹 but I will go back to fasting as it has done miracles for my health 👌🏻 bless you for your valuable time ❤
trust your body. like hippocrates said, if we aren’t our own doctors, we are fools.
Thanks dr. Fung. This helps calm my mind.
Anything the FDA says I just do the opposite. I recommend reading “Health and Beauty Mastery” by Julian Bannet, that book is a real eye opener about shocking stuff health industry is doing! I completely changed my habits
totally agree
This book is scam
Be careful people
Thanks for answering my protein questions. I was unsure about how much protein to eat and this video is a big help.
Thank you Dr fung 🙏🏼
