Can you please do a video on high protein diets? I'm considering eating 150+ grams of protein on my 16/8 IF days in order to curb hunger and not binge and regain fat from my 72hr fasts. But I've heard protein creates an insulin response, is that something I should be worried about?

[@Teslawaverunner]

Could you possibly do an analysis on the Phoenix Protocol ( August Dunning ) specifically Chapter 3 on water fasting. According to this book an extended water fast beyond a couple of days will result in heart muscle loss ! This sounds counter intuitive , how would we have survived in Hunter gatherer days if by drinking water while on a hunt ( and therefore not eating food ) the heart was destroyed. The medical information in Chapter 3 looks like it is well referenced to medical reports so not easily dismissed. Would appreciate an MD analysis thx

🎯 Key Takeaways for quick navigation: 01:10 🏋️‍♂️ *Muscle growth or shrinkage depends on stress applied, not solely on diet. Adequate nutrition prevents using muscle for fuel unless body fat percentage is extremely low.* 02:20 📊 *Alternate daily fasting did not decrease lean mass (including muscle); in fact, it potentially increased it, compared to fat loss.* 03:42 🔄 *Fasting strategies were more effective at preserving lean mass (muscle) compared to chronic calorie restriction, with a 4x better result in lean mass preservation.* 04:09 ⚖️ *Growth hormone plays a crucial role in lean tissue maintenance. Fasting increases growth hormone, preserving lean muscle while promoting fat loss, without causing side effects like injected growth hormone.* 06:29 🍲 *Fasting utilizes glucose and fat stores for energy, not protein. Body doesn't use muscle for fuel if other energy sources are available.* 07:09 🕒 *Terry Crews practices a 16-hour daily fast, followed by an 8-hour eating window. Exercising in a fasted state can increase training intensity and recovery due to hormonal changes.* 08:04 🌟 *Training in a fasted state, as done by Terry Crews and other celebrities, offers benefits such as heightened training ability, faster recovery, and anti-aging benefits without significant side effects.*

I'm about to turn 34 and had done intermittent fasting maybe around 15 years ago... I liked it then but never knew HOW it worked or WHY. After a 7 year hiatus from fitness and I.F, I started the gym again but this time with more research and knowledge and a plan. I've been at the gym for about 1.5 years now starting with training 2 - 3 times a week for a year and only recently 6 days a week. I have always wondered why and how I could be building muscle even though I'm not having food or protein in my anabolic window after training and now I know why. I'm almost at the best shape I've ever been in my life. I'm close to a body builders physique and I couldn't be happier so far. Thanks Jason for explaining this it finally fills in the blanks as to what I've always wondered.

This doctor I think was talking about NOT loosing muscle, not about gaining muscle. We have fuel in our body for about 1 day as glycogen. But when fasting where we get protein which we need all the time for blood for example?! I think we need to eat protein every day for just not to lose muscle.

The Bible tells us to fast to break strongholds in our lives, spiritual discernment and gifts. To humble ourselves before the Most High God that He may incline His ears to our prayers.

I´m not religious but in fact, fasting brings a lot of benefits for the body. Modern life usually has no clue what it means to have nothing to eat for a while. We can stuff our belly 24/7 which absolutely isn´t natural. Many modern jobs are based on sitting or moving only a few steps daily, but our body is made to move a lot.

God still loved him. Yes, that is the God that I serve, and I would that all men would seek Him and be saved but that isn't reality. People don't know God because they never started the journey. That road begins with the Word... John 1:1-2 [1] In the beginning was the Word, and the Word was with God, and the Word was God. [2] The same was in the beginning with God. [3] All things were made by him; and without him was not any thing made that was made." We have a real code in God's Word.

I had no headaches, and the difficult first 3 days were not as much of a grind to get through. I think everyone should try a 7-day fast once in there life time to gain control over your mind.

Hi @Jason Fung, I was wondering if you could create a video about practising intermittent fasting together with endurance sports such us marathon running or cycling for 4+ hours. There aren't many good resources about this topic especially regarding the nutrition during the event (if any/when/how much). Thanks a lot for all the content.

[@michaellongstreath2405]

Always enjoy the good information, thanks Jason

[@joshuasethhill3518]

I've been intermittent fasting for a while now, but want to try a longer fast to lose weight. I'm glad to know I don't need to worry about muscle loss 😃

[@mohammedmedhat5496]

You should make 16:8 it is better intermittent fasting with the P:E diet for the best building muscle 💪 you will see

[@mercedezlucke-benedict1122]

You changed my life Dr. Fung!

[@jamtmann]

Awesome….I have been a professor teaching exercise physiology for over 30 years, and you have really opened my eyes. Thank you !!

[@ivoivic2448]

you're a pretty shitty professor if you just now learned something new.

[@christinahuck379]

Thank you! Thank you! Thank you! You are sanity/logic in an insane/illogical world.

It's so weird but after 3 months of OMAD keto coupled with 2-3 times/week light bodyweight exercise and an occasional 48-72 hour water fast, I haven't lost a ton of weight from my starting ~230-235lbs (~10-15 pounds) but I am much leaner and more muscular looking. I fit in my swim shorts that I used to have to be around 205-210lbs to fit in. I guess my growth hormone being high all the time is playing a big role in this.

[@animesloversunited9069]

Cuz you gained muscle, that's the win

[@Black-Panther94]

Thanks man. This video was very educational and inspired me to incorporate fasting to my body fat reduction routing.

[@xCestLaVie1]

Muscle wasting is so hard to happen in the first place. A patient needs to be in bed for weeks with inadequate nutrition to have atrophy. I'm noting a lot of bro science youtubers are making it seem as though this happens in the span of hours. It just gets everyone anxious and misinformed.

[@emochinchilla]

Great info. Thank you for taking the time!

[@buraksaglam1586]

Dr Fung can you please talk about skin deformation on your next videos? ,Most of the people think that their skin will be deformated if they rapidly lose weight because of the fasting.

[@LTPottenger]

How quick you lose it doesn't matter, but you will not be able to get rid of it all through fasting in some cases regardless. Some people are going to look like a deflated beach ball after losing weight because they don't have a big frame and were carrying a ton of fat. Fasting helps a bit to eat skin but people in that case will have to get surgery.

[@JohnKowalskyDrive]

The loose skin problem happened a long time ago, when someone gained too much fat or has been too big for a long time. it's not because of the fasting/weight loss. I know because I've had tears all over my skin at the age of 12 from being obese and a bit of loose skin at 32 now after losing the excess fat. So it depends on your baseline.

[@namrata29t]

Thanks for clearing my doubt

[@rainyjazz9849]

Just wow !

[@nextalphaa1222]

Great information 💚🤍

[@bbradley280]

Yep started fasting and lost 40lbs then, started a weight lifting regiment gaining 10lbs of muscle. Feel like I’m in better shape then I was at 30.

[@sokingssddk]

How long did putting on 10lbs of muscles take?

[@bbradley280]

@@sokingssddk probably 3 months

[@elizabethkoenig5185]

Good for you, Bradly! I have lost over 80 lbs in the past 7 months, while gaining muscle.

[@PeaceIsYeshua]

@@bbradley280 How old are you? Age is a _huge_ factor when it comes to regaining muscle.

[@anthonylong601]

Thankyou from downunder Jason. I fast two days a week and was losing a little bit of muscle. After your video I now think the muscle loss might be due to age (60).

[@james197091]

Great Video Jason! I’m finding great muscle building amd fat loss with fasting from 2pm then training fasted at 6:30am the next morning then able to lower cortisol by eating pretty much after training .....till 2pm....I’ve also read studies where this works in better with the circadian rythm as you’re consuming most calories in the day earlier then fasting evening / night the way our bodies are designed , with restorative/ repair processes occuring at night in the absence of insulin .....my sleep has been much deeper and better quality since doing this too ......once a week I will have a carb only meal at around 5 or 6 to restore glycogen for training and the benefit is also serotonin for sleep , but I don’t eat anything after sunset and I’m finding it so much better in many ways !

[@396Darwin]

Thank you, Dr Jason. Been doing fasted workouts and fasted cardio over the course of this Quarantine Period. Never been felt better. And most of all, I do OMAD eating pattern along with Low Carb High Fat Diet.

[@rodneybooth4069]

On EF I get a little weak and whine when I talk on the third day but I can lift the same weights as usual So I figure I'm not losing muscle on a 72 hr fast. I went to ADF and no issues so that's my go to now.

[@Riosgirl98]

I find ADF to be amazing for cognitive clarity, strength and just overall wellbeing. It's a game changer for me & my mom. Great to see other people getting benefit from it too. 😊

[@dennispickard7743]

Rodney Booth yup , it’s the way to go - every now and I’ll do a week of 2 days fasting and 1 day normal. Fast Monday & Tuesday- eat on Wednesday, fast Thursday & Friday and eat normal Saturday &sunday . 8 days has been my longest and trained 6 of the days with lighter weights and more sets . But ADF has all the positives for me .

[@NgocLe-sn2oq]

Thank you Dr. Fung

[@TheRealCoyote]

Very, very interesting! And sad...because many of us have been given wrong information all our lives.

[@elizabethkoenig5185]

I just wish I'd known this years ago!

[@jameswoodall9261]

Your teaaching makes it easy to do the right thing. Now we know "WHY."

[@davidbrianwells2058]

I've been fasting for two days but now I'm gonna have a pie.

[@KuumbaOnline]

One of the best videos so far!!! Thanks dr fung

[@fiscolorado656]

Dang Dr. Fung. I didn't know you could do one armed pull ups.

You rule Jason. Thank you
