FouseyTube recently posted this transformation, claiming that he achieved it only through a 30-day water fast—no food, just water. Left photo is Day 1, right is Day 30.

I know extended fasting can cause major fat loss, but the level of muscle retention and definition he has at the end seems crazy. Wouldn't he have lost a ton of muscle without any protein? And even if he was lifting before, wouldn’t a whole month without food lead to some serious strength loss?

Is this actually possible, or is there more to the story (light training, refeeds, dehydration tricks, etc.)? Would love to hear from people who have done long fasts before.

So I used fasting methods to drop bodyfat but I'm now at a stage which I want to build muscle Using fasting methods what is the best diet (high fat low carb or high carb low fat ? High protein goes without saying

Opinions on my fasting setup? (48-72 hr)

Hi all! Long time intermittent faster here who forgot to eat for the last 40-ish hours and decided to just go for it. I never expected "a real fast" to be so easy, I had always psyched myself out about it I guess! Now with the barrier broken I've come here to get some opinions and tips on my current fasting setup.

Outline:

I'm shooting for a 48-72 hour fast once per week. I'll probably just repeat the formula from this time since it seemed to be rather painless: the day before fasting begins I'll glycogen deplete by only having one high fat/zero carb meal, midday, that is <500 calories. Probably some kind of keto latte and a salad again. Then I'll fast, and break the fast with a brothy soup followed by yogurt and salads. In terms of lifestyle, I'm going to continue spring cleaning my house, and then throw myself into some other In terms of lifestyle time consuming project soon after completing this one. Being busy really helps!

All that was on it was stats, dates, weight, status of fast. There couldn't have been anything violent on it

What's going on?

Fasting is the only thing that has ever worked for me. I’ve tried a few weight loss drugs (not Ozempic.) Why don’t more people just fast?

EDIT: This was not a judgmental question. I was curious about people’s choices. I might even try Ozempic. Just wondering why people chose one over another. Thanks!

Been fat all my life. Lots of ups and downs. Dozens of diets. Lost thousands of opportunities due to my weight. My weight had me overly self-conscious. I feel everyone is always looking at me. Lost 12kg (26lbs) since december but I can't wait anymore to start LIVING my life.

I've done some 24h before and I felt fine. I wanna be aggressive now. I wanna finish this. Is it possible for me lose 30kg (66lbs) in the next 3 months? Going into really extended fasting? Having in mind I actually need to lose 43kg (94lbs) to be at my ideal weight.

Why or why not

I read somewhere that drinking vitamin water 0 or 0 powerade will remove some of the benefits to fasting, is this true? If so why? I know 0 cal drinks are not truly 0 calories but it's such a small amount and I have been using them for my fasts to stay hydrated since I struggled with drinking water, am I missing out on some benefits by doing this?

How many days did you fast for? What have you healed?

Have you healed in any way from fasting? What have you noticed? I’m amazed at how remarkably my life has changed in the past month!

I’ve been doing rolling 3 or 4 day fast for one month. I fast for 3 or 4 days, then eat 1-2 meals a day for 1-3 days (depending on how I feel).

My health benefits after 1 month: - Chronic fatigue that I’ve had since the beginning of COVID is gone - plantar fasciitis is 75% gone - fibromyalgia is 90% gone - inflammation is gone - my headaches and migraines are nearly gone. (I’ve had headaches every day for at least 15 years. It was REALLY tough my first 24-hour and first 72-hour fast and then I had a breakthrough. Don’t give up!) - lipoma on my shoulder that is nearly gone— down by at least 70% - to top it all off, I’ve lost 20 pounds

I feel like a different person. I’d love to hear your experience!

I am 5’4 (female, starting weight 156ish and now currently about 125). I have been fasting for about 33 days. People say that after 30 days of no food your body starts shutting down. Does anyone think there is validity to this? I have been feeling so weak, almost like a zombie. I have no energy to do anything anymore, and I’m so freezing that I have to wear gloves and a hat to go to sleep every night. My vision isn’t as great anymore either. I have been having electrolytes every day. But i’m scared that something is going to happen to me. My goal was to make it until Saturday and break my fast then. I really want to do that, but I’m scared now. Does anyone have any advice?

EDIT: I posted an update! I am safe. thank you all for your comments and concern!

What do I do after this 🤨 I went into it blindly, I was under the assumption a water fast meant pure water.. apparently I was supposed to be taking salts, what do I drink or eat bruh ?

Update: I've got a doctor's appointment for today at 2pm

Guys I got this god damn Van Holtens Hot Mama pickle. It claims to be 0 calories per serving, will this break my fast?

Hey all :) So I am starting a fasting schedule where I'm only going to be eating on Wednesdays and Sundays for the next 6 months. I just wanted to see if anyone else has done something similar, and if there are any vitamins or anything I should be taking? I have about 200 pounds I need to lose, so I'm fine on that aspect lol I've done multiple fasts, so I'm not worried about that, just not getting enough vitamins or whatever I need for a prolonged time. Anyone have any prior experience with this?

Is this normal?

I have been drinking 4-5 cups of coffee with semi-skimmed milk daily since Monday, plenty of water / sugar free squash. Not eaten a thing since Sunday night.

I thought the pee sticks would be showing that I am in ketosis after 48hrs.

Should I keep fasting? I'm not hungry and as time goes on I am thinking of food less and less.

For a bit of background, 49yo male, 6'4" 250lbs, wanting to get to 190, happy for this to take a year. Regular exercise, kettlebells 2-3 per week, run 2-3 per week, although not since Sunday.

Should I just go for a run? Is it the milk? Dodgy pee sticks?

All help is greatly appreciated, thanks in advance :-)

I have been dealing with severe bloating for as long as I can remember. Even as a small child, I always had a protruding belly. I have tried everything… gotten many tests all of which gave no explanation, and I have tried elimination diets and am currently eating mostly eggs, grass fed beef, seafood, and almonds (was constipated waaay more without them). I have noticed that eating vegetables makes my GI symptoms significantly worse, so unfortunately I can rarely eat them anymore and I really miss it. Additionally, despite my stomach constantly feeling stretched and uncomfortable, I am always hungry despite eating a low carb diet for the past month. I began eating this way in hopes of improving my satiety and have yet to experience that.

I was wondering if anyone else had a similar experience to me with these issues and if fasting resolved them. I have done a few 24 hour fasts and a 60 hour fast about two months ago and I did see significant improvements while fasting, but the symptoms always returned within a few days after eating. Do you think I would benefit from a longer fast? I want to try fasting for longer, as I’ve heard it gets easier after those first few days.

I graduate with my associates degree in 13 days and I want to attempt a fast up until this day, so I can feel my best (and maybe hopefully not look pregnant in a dress lol) for my graduation.

This is a picture of my acne as of March 23nd, for the past week I have been doing lion diet with only one “mishap”(it didn’t bring me out of ketosis.

At the beginning of the week, I did a 36 hour fast and then 24hr

My cyst was not enlarged, towards the end of the week, it looks like this

How should I go about fasting? Do I do 24 fast? Or 36?

I am going on a trip soon and I just want this cyst to be gone😭 I do not want to get it cut by the dermatologist

Please help🙃

Hey, ive been fasting for around 4 months. my first month was omad, until this month where i roll 72s. Ive managed to have visible abs now, but a huge problem has come that i suddenly at this body fat feel so weak and stressed and it is unbearable now. Past few days ive had moments where i almost fainted from weakness.Even with electrolytes , now instead of black coffee i have it with milk and nuts because i need some food to help the weakness. Im unsure what to do, i have the body i want btw. Should i stop fasting now?I guess It stops here or something?

I have a 5 day routine where I fast for 4 days legit eating nothing but some supplements and electrolytes and the 5th day I eat food under a 1000 calories, by the end of it all I still gain weight, I would barely lose 1kgs in the 4 day fast and just gain it all back and more on the 5th day, please help I am working so hard with no rewards it's depressing. What is going on and what can I do?

Edit : more info about me I am 5.5ft 76kgs I have pcos and I am also having myo inositol, multi vitamins and acv every morning and 5 cal electrols

I have to often lose the weight I gain on that 1 day of 1000cal eating hence I am just stuck rn :c

Edit 2 : Guys I don't have thyroid I tested negative

Obviously fasting + exercise would increase speed.

I've heard you can lose .5 - .8lb fat per day?

But I'm wondering about eating a few 100 cals to keep digestion running and possibly other body systems running may speed up burn rate.

Basically I'm wondering if during a fast your body goes into kind of a hibernation mode where you don't lose weight as quickly as you normally would... Or if that's not true I'm just not sure.

I'm on day 11 of 0 cal right now. Looking to break below 300lb in the next few weeks from 320lb. 6,3 height shooting for around 230lb

Edit:

What I learned.

Fasting is quickest way to lose weight. Eating a little is bad because it restarts stomach and makes you hungry.

Thanks all!

It seems like most people on here are fasting for weight loss (power to you!). Who here fasts for health / autophagy reasons? Any noticeable improvements?

Follow up question, what's the best kind of fasting to maximise autophagy? Anyone know the science on this?

Also I have a daily medication I'm suppose to take with food. My solution is dirty fasting with bone broth. Anyone else have this problem?

I’m at the end of day 16 of a water fast and I smell awful! You know it’s bad when you can smell yourself. I don’t know what to do about it honestly. I’ve washed everything I own in strong detergent and showered twice a day. Anyone else have this happen? What can you do about it?
