What Happens to Your Body After 1, 3, and 7 Days Without Food?

I'm on water fast too and it gets hard after 24 hours. Electrolytes are a must. Cheers!

Also dude, you left my gold signal program that rejected me lol! Tufts 😅

❤❤❤ I was thinking about intermitten fasting yesterday it was like you read my mind lol😅

Thanks for sharing your knowledge ❤
You must've been a scientist but I respect doctors more 🤭

but how long can you sruvive without food???

How long can you survive without finishing residency?

Excellent video. I just mentioned to the neighbor yesterday that I'm doing a water fast. She told me to be careful because she knows someone that died when they reintroduced food. So I have been allowing a couple things ... A cherry-strawberry kefir smoothie w/cinnamon & turmeric, an avocado, and some peanuts. To be honest, if this doesn't start making me feel better soon, I'm happy to say sayonara.

Very comprehensive video. I also read about the recent article, scares me a little but moderation is best!
Minimalism in every way of life is the best thing.

Thank you very much for sharing your knowledge and your experience with us. Highly appreciated.

I read that it's normal to fast. Early humans were scavengers, they ate whenever they found food sources. Other times, they went without. We have more fat cells than other primates..to allow for our gorging/fasting mode.

Thank you Zach for this information filled video. I always wondered what fasting can do to us or if it has any benefits at all!



Thank you for illuminating us.

Many thanks and love to you. ❤️

May you stay the way you are. ☺️

I knew you would be perfect for this kind of Dr-Mike video format.
Keep following his example.
But don't interview presidential candidates...

I can totally agree to what Zach says in this video. After my surgeries, I didn't eat at all and was only drinking, so I have lost very swiftly my weight. But, after I started to eat normal (after a couple of months) I've gained even more weight, although I did not eat sugar and practiced intermittent fasting. So only sport and sleep can help. Thank you so much for your advices. P.S.: As I watched you eating bread I got hungry, although I was not hungry before I started to watch your videos.

First, glucose is used up then protein is converted to glucose and when that is depleted, fat is converted to glucose. Fat is the last resource available for energy, this is why it’s so hard to lose weight!

Hello doctor zach, great video, please make a video on skin tips also.. how to take care of skin.. appreciate it.. thanks a lot

❤🎉

I’ve done 7 days multiple times. Never regretted doing it.

Aside from the video content, I wanted to tell you that I really like what you present and I love your personality because you are kind and positive and always make me smile.
love you
💗

Another great video, Zach!
Thanks, mate!
Have a lovely weekend!
Cheers from Brazil!

This year I fasted 30 days and I felt better every day. It was so awesome. I hope I can do it again one day.

It is NOT true that your body reduces muscle while long time fasting. Look at different studies from people who fasted 30 - 50 days. They GREW muscle while fasting and doing cardio plus working out.

This video is a joke. Long time fasting CURED all my problems. And I am definitely not the only one! 😂

Hi Zach, wow what a great video! Love it how you covered also scientific studies and the overall educational content is just amazing! Keep going! Many greetings from a biomedical scientist 🙂

Okay Z, how long until you aren’t pretty anymore?😘

med school interview questions:
if you were a banana, would you be ripe or unripe?

It was interesting. I want to hear more about intermittent fasting

What's happen when you don't get sleep?

Sad what you have become to. Follow your path and everything but please, unless you don't return to residency, at least try to create something new, some niche content. Whatever you are trying right now, is extremely satured.

Indeed, it feels like the Hunger Games out there

Zach, I think you'd be a great college professor...you meet all the requirements and some more!

I've had good experiences with both intermittent and long fasts using generous amounts of electrolytes. Dr. Jason Fung is perhaps the best resource on fasting.

I like the way you say "CAN KIIL YOU" 😒😂
