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! 🌟

Good day Dr.jason
Awesome piece of info
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.
A Great doctor
Thanks Dr. Fung.
Re: fasting, do non-caloric sweeteners count as breaking your fast / stimulating an insulin response?
(can I still have a coffee with say a Splenda in the morning before breaking my fast at lunch?)
Yes. Sweeteners raise insulin. And the goal of fasting is, on the contrary, to lower it. So it is better not to use sweeteners during fasting: it slows down lipolysis.
I love the way you teach!! Straight to the point! ♥️
Thank you Dr. Jason. Very helpful information.
Thanks so much for this information! I have had to limit my protein intake to Apprx 25 g per meal and have been concerned that I wasn’t getting enough protein per day based on the input from other people in the fasting and carnivore space.
Thank you
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!
This is another one of those things I heard that never seemed to make sense – “if you ‘starve’ yourself, you will lose muscle” glad my common sense backed me up yet again.
Dr Fung is a HERO
Thank you sir
Please make a separate video on how skinny people can gain muscle!
Thank you for another no-nonsense informative video, Dr. Fung.
Thank you! Great video!
Doc thanks for this video. I’ve had several Dexa scans and had no idea about some of the flaws. I still see value in them, but thanks to you I’m better informed.
You should do a podcast with Dr. Mike Israetel, please do a debate with him
Plz more on fasting and muscle loss cause its the only topic that sets me back. thansk jason
