9 Studies on 20-48 Hour Prolonged Fasting and Benefits (2023)

In this video we dive deep into the science of 36-hour and 48-hour extended fasting. Discover the latest scientific studies showing some of the key promises of why it can make sense to do a 48-hour or 2 day fast which in my opinion may be the perfect prolonged fasting length to do every so often for both weight loss and health benefits.

We cover 9 studies ranging from IGF-1, HGH or Human Growth Hormone, Cancer Research, Autophagy, Immunity, the general timeline of fasting, gut bacteria and microbiome research and answer questions like when does autophagy start and much more!

Reminds of the scene from the film dracula untold, the line " if you can go 3 days without feeding, you will be free of the curse " when you think about it the concept of fasting as a healing mechanism is everywhere

i found your video through a reddit post and I really like the style of your videos! :) so interesting

[cattleprods]

Fantastic video, I lift weights 2-3x/week and enjoy fasting, frequent OMAD (2-3x weekly), weekly 48 hr fasting, quarterly 3-day. Feel 👍 and wouldn’t go back…ty again

I like your cleaning the house comparison. I’m just about finished a 72 hour Fast. I’m hoping to do this once a month. Otherwise I do a 20 hour daily Fast.

I did a 55 DAY water only fast last year. I feel like I did miracles for my health. No food, no calories for almost TWO MONTHS. I had so much energy, my hunger was completely gone and mind was super clear and sharp! I didn’t lose any muscle. My muscles kept super strong! I didn’t need any kind of medical supervision. I only took in electrolytes, vital sea salt, trace minerals and magnesium. None of these had any calories at all.

Great timing - just starting a 48hr fast (at 16hrs) after not doing any fasting for months. Good to have a reminder of the benefits. Glad you mentioned the exercise when fasting because I've often done a massive workout on day 2 and then had to break the fast because of instant hunger at < 48 hrs. Nothing but walking this time.

Awesome info for such a new channel, really well done JOE! Look into bannanas for lose skin, David Goggins mentions it in his book I believe.

What about light resistance exercises to minimize muscle loss in upto 48 hour fast?

Enjoyed watching this video as you have a lot of great info. Sure wish you would do a video of your own story which would be of interest to me and I’m sure a great deal of people. Especially photos of yourself 100lbs heavier and what you did and the mistakes along the way. I am one month into my 100lb weight loss journey and love to see and hear others to learn by and to keep motivated. Keep up the great videos.

I am on day 4 of omad FYI down 19 pounds. and I want to try a 36 hr fast this week. Wed. I feel I really need to dive way deep as my current health is in a very very bad place.
Just wanted to try and connect with others to hopefully have others to connect with.

I do intermittent fasting by skipping breakfast permanently. About 16 to 18 hours no food. Periodically, longer water fasts. Tried different lengths, up to 5 days. Lately, 48 to 60 hours about twice a month. Lifting weights 2 times a week. I don't eat sugar, do eat fruits Feel fine.

[bethaminkhan]

Which supplements encourage autophagy? Can you do a video on this, please?

[bairfreedom]

I'm doing rolling 48's. One large meal every 48 hrs. I didn't end up eating a ton on my meal after 48 hrs. 2 large sausage and egg burritos and a corn dog. Didn't even break 1 days calorie intake.

[derrickparker]

I use the supplement called hydroglyph it a game change it even when you're doing a 24-hour or 48 hour fast you won't lose no muscle because the ingredients in here it's very powerful

[nissathompson]

False on type 1 not being able to fast. My son has done shorter fasts, 24 hours or less and he is fine.

[deangerrard]

Just another video everyone is jumping on FASTING
