After 24h of waterfasting my Ketostrips barely change color, deep purple after 48h! Do I even burn any fat in 24h, or does my body just use glycogen which it refills when I eat again and no actual bodyfat was...
Hi everyone, I have been trying to cut some fat, I have to burn around 10kg of fat to achieve my desire goal. I find dieting more demanding that I was expecting, I have a pretty wild and busy schedule for...
I know consuming anything with calories technically breaks a fast, and that the Celsius has about 10 per can, but from a purely fat burning perspective does it matter? Especially if i’m using it as a pre workout and water...
Hi all, I've been fat at some points in my childhood which made excess fat and skin on hands and hips. I'm pretty skinny now, 200lbs at 6'6 but I still have good amounts of fat on the hips. I...
Started IF January 07, 2022, doing 18:6 and already feeling great. Lost 3.5 lbs already (assuming mostly water weight). 32m 6'3" started at 260 lbs. Mainly eating twice a day (12pm and 6pm, with the odd snack). Now when I am...
My understanding is fat burning happens when your insulin is at a lower level and your body depletes all it's glycogen. Let's say you do cardio when you start your fast, will this increase the amount of time you'll be...
I've been using Zero, and I know not to give too much credence to the zones it gives, as they are guidelines and suggestions. Without actually measuring blood glucose I would be hard pressed to be accurate. Currently doing 18:6 intermittent...
Hey, I’m new to the whole fasting thing and I’m starting out with intermittent fasting. Am I still burning fat while fasting for the 16 hours or do I need to fast longer to burn fat?
Im new… i read the wiki, but does fasting help you burn fat or do you only lose water weight? What are some good methods to use to burn fat and stuff…sorry i’m clueless, everyone seems very nice in this...
Hey Everyone, So I used to follow the Snake Juice and fast for 5-days each week, but it has become difficult as hell recently. I no longer have the strength to work out and fast for such a period of time. During...
Is noon-1pm the ideal time to start your OMAD? I think it is because: The sun is brightest during the mid point day - our biorhythms are most awake at this time including digestion Fasting in the morning is relatively easy - esp...
Over the past month I’ve been eating 1500 calories a day, doing 16:8 IF and cardio for 30 minutes a day. I’ve seen results, but sometimes my schedule gets in the way. Nights like tonight are not uncommon. My responsibility...
Does running while fasting enhance the fat burn and calorie burn effects? Anyone run fasted? Looking to start and to hear your tips!
If I fast for more than 16 hours and eat in a shorter window will this enhance my weight loss or body fat loss?
IF newbie here. I’m currently on day 2, slowly testing the waters to see if this lifestyle is for me. I’m curious—as a long time follower of CICO—will IF still benefit me assuming I know my TDEE and am eating...
It’s been working for me because I also pair it with a calorie deficit. But I can’t tell if it’s the OMAD alone or the calorie deficit that is helping me to lose weight. I do realize the longer you...
i see different things. some sources said that 18 hours did as much as 20 hours. if that’s the case then why do people try to fast longer? sometimes even days? what does it do? after a certain point does your...
This guy has a good video on efficiency of Dry Fasting: https://youtu.be/GeQYsBMxW1I?t=1797 (29:57 for conclusion, 31:38 for adjusted BMR). But, since this is only 40 hours Dry Fasted, he explains that his body is probably not functioning on 100% fat...
Hi! I am not currently overweight (I’m 156cm/ 5’1 and 50kg/ 110lbs), but I would like to lose about 3kg/ 7lbs to get rid of some pouchy fat around my waist, and stubborn fat around my arms and thighs. I...
I weigh about 240lbs rn with a lot of built up muscle from working out for years but I also have gained some fat. How would you recommend I fast to optimize fat burn and keep as much muscle and...
I only have until I start my new job to do extended fasts so I’m in a bit of a time crunch. I’m on day 5 of a fast rn. Debating if I should break it today to go to...
I’ve seen several posts extolling the benefits of weight lifting in a fasted state and decided to do some (casual/Google) research to learn more about it. For some background: I normally break my fast the night before a gym session,...
Im at about 28 hrs dry. Longer total fast probably 48 plus hours fasting. I have been unrinating regularly. My cotton mouth is not nearly as bad as this morning. I am mostly headache free. Occasional mild headache! I...

Good morning everyone, This is my second 7 day water fast in 4 -5 years. Now I can't really remember how I survived the first one, just know that I did and how amazing I felt afterwards. Im 32 just for...
I’ve read conflicting studies. Anybody know if there’s a scientific consensus on whether or not it’s possible to maintain muscle mass while doing an extended (2+) day fast? I’ve read that growth hormone surges after around 24 hours, and that...
Hello all, hopefully I will get a response for this post. I have been fasting for a few years (36 hrs to 110hrs). I am currently on medication that needs protein to work. However, I really want to do a...
Disclaimer: it looks quite disgusting. But if anyone could offer me some information I'd be really grateful. What the heck is that? It smelled awful, and usually my dumps have a mild odor and look "healthy" (appropriate shape, texture and color)....
ive been bulking hard since the summer, currently at 17% bodyfat. my goal is to get to 12% by summer. i want to cut by fasting. I've never done a cut this way, usually, I've done a calorie-restricted cut in...
Hey, I’m a high schooler who wants to fast to lose weight/fat (and gain muscle). I was thinking of taking vitamin pills every day (multivitamins with most of my daily intake), as well as, and I know this doesn’t count...
If I take a cup of milk before bed, will it prevent autophagy?
I've been looking at some flavored green tea and herbal tea options to suppress appetite and increase fat burn during my fasting window. How do I tell if a particular tea will end my fast? Should I avoid flavored teas...
Hi so starting February 1st I realized that I can fast again after not being able to for 2+ years and am down 10 pounds in the past couple of days through rolling 48s But for the past 3 days...
I'm on day 9 of my water fast and I've transitioned to a state where the majority of the weight I'm losing is muscle and not fat. Does anyone have any tips or insight regarding how to avoid this -...
hi all, I'm curious what you guys have seen as an ideal fasting length, to cut fat and preserve muscle. I'd seen Dr. Jason Fung mention that after 15 days or so the metabolic rate slows down, but that up...
Hi, I am currently on day 7 of what I hope to be a 21 day water fast. I supplement with electrolytes, and honestly feel pretty good. I read up on the science of fasting, and how as your body...
I’ve been thinking about this for a while now… The building blocks of muscle are protein so we need protein to grow muscle after hypertrophy. Fasting creates accelerated GH which promotes growth while also switching to ketones as fuel so...
I am doing somewhere between 16 and 18 hours of fasting most days. The zero app tells me I'm in fat burning after 16 hours, but thats a generic time. How would I know if my metabolism is slow and...
In my research, I’ve read this increases the efficacy of the fast and burns more fat. Thoughts? Should I try to schedule workouts during my fast within reason? Thank you
I am on day 7 of fast ...I want to do a 30 day but I read couple of bloggers saying there was barely any wt loss from day 21 to day 30. Kindly pour in your experience and help...
Recently I wrote an article that explores why fasting is a better way to reduce body fat than just counting calories. Here are some key takeaways: --Nowadays people are eat 5 or 6 times a day, rather than just 3 --Eating all day...

So I’ve always had a hard time losing weight. I can literally workout every day, and eat like salmon and spinach and barely anything else in a day. I just won’t budge one lb. However I’ve recently discovered with fasting,...
Obviously you shouldn't eat an absolute massive amount of food but would you still lose weight if you had maybe a normal sized dinner and then snacked on candy and other stuff during the eating window? I'm doing 20 hour...
So I’m underweight but doing 3 to 5 days dry fasts to heal my gut. I usually deplete my glycogen stores before fast to enter ketosis quicker. I was thinking, what if I have some carbs(via fruit) to stock up...
I plan to do rolling 72s for the next month, purely for the weight loss, that’s all I care about. Does exercise make any difference when water fasting for 3 days, and if so, what type of exercise? Like walking...
I am right smack in the middle of fasting for 21 days and I've been using it as a learning tool about my body. I also chose fasting due to claims that it won't reduce my metabolism in the long...
So I know a lot of you have lots of info around on fasting. In particular what I'm looking for relates to respiratory quotient (RQ) and fasting. So I think most of us are generally aware of the \~3 day...
Despite having done so much research into intermittent fasting and calorie restriction, I’m still super unclear on some of the mechanisms of the two: i If the role of intermittent fasting in fat loss is to lower insulin so that the...
So to cut to the chase, let's say I am doing a diet of about 1200 calories daily and do a 16/8(fasting/not fasting) fasting regimen. Obviously it's fine to once in a while break the fast early because something came...

Hey babes, I'm very new to the work of fasting and I'm so excited that this sub was created the week I decided to investigate more! From my reading so far, it seems like the first 24-72 hours of a long...
Hi peeps Doing 16:8 fast at the moment , sometimes for longer and it's going great, but I just feel I can help improve myself a bit better, Do you have any tips to help melt away fat or tricks...
There are a lot of details here. All of this comes from using the scientific method to reverse engineer nutrition, performance, mental clarity, and weight release. You must experiment. **\[Progress photo at the end\]** Here’s exactly what I do, big picture: Fast...
What if I started with 1 day dry fast to deplete glycogen in my liver quickly, then continue for 6 days water fasting? I think my body would go into forced ketosis after a day of dry fasting, and I'll...

Just listened to a podcast with Dr Fung and he said that between 24h and 36h fasting you burn protein and after 36h you start burning body fat. What do I burn during the first 24h fast then?
So I used to fast in the past and lost 100 pounds in 6 months and recently started fasting again February 1st Went from 340 to 330 in 2 days but since February 5 I’ve been fluctuating between 335 and...

I did a dry fast for 48 hours and a few more like 5-6 and finally managed to hit my desired weight and wish to maintain it from now. Now I'm a bit nervous about breaking the fast. What I...
Hi- quick question to everyone who read Dr. Fung's Obesity Code: What did he say about weight loss and breaking long term fast? I know that after day 3, we burn our fat and maintain good metabolism. I am so bored...
What's the best way to deplete your body's glycogen while fasting? I usually do the elliptical on the fat burn setting for 20-30 min near the end of my fast. Just want some other options. Thanks.
I'm interested to hear what the overall take on this from fasters who understand the hormonal impact of fasting on the body. Dr. Fung rarely qualifies this statement and uses black and white terminology such as "the CICO theory has...
Does anyone else suffer from diminishing returns when fasting for weight loss after 7 or maybe 5 days? I blend exercise with fasting for maximum fat burning and I'm starting to notice that - while the first 5-7 days are usually...
How much do you like to take? And when? Edit: To be clear:. My hope is to feel full more often on fasting days,. so I resist the temptation to eat. (I often break my fast 'early').
Hi I’m new here, been doing 16/8 5 or 6 days a week for four weeks and I weighed myself for the first time today and I didn’t even lose a pound. Feeling really discouraged. I have a vacation coming...
I tried IF last year by skipping dinner. But my family always eats and became impossible to avoid eating. I'm from South America, and here dinner is usually after 9PM, in my home we usually ate dinner around 10 PM...

Kind of a followup question from my other one. If hypothetically, i maintain a 500 calorie deficit daily (1600 calories) WITHOUT IF compared to doing it with IF, would there be a difference in outcome after lets say, a year...
I genuinely thought whole milk will break a fast however, I am reading the complete guide to fasting by Dr Jason Fung and it seems to list whole milk as something you can add to coffee. Here is the list...
Any tricks before a fast to not feel like shit?
I’ve always been a big “eat protein or drink a protein shake immediately after you workout guy” but I want to start interment fasting and I lift in the morning right after I wake up. Should I not drink a...
Im doing a lot of heavy weight excersise, and i want to build muscles but also loose weight. I love fasting because it’s so easy to loose weight and feel my very best at the same time, but im a...
So a bit of background, I had read an article about fasting to loose non-functional muscle mass [here](http://online.fliphtml5.com/mrom/hiie/) (used in cyclists in the article to loose upper body muscle), And wanted to apply it myself to help improve my strength to...
So I've been fasting for a month now and I just finished a 46ish hour fast and it says I burned about 35hours of fat. How does that work? Like does it burn fat in general in the body or?...
As usual with fasting, the scientific studies seem to be conflicted or inconclusive. I was listening to [this](https://www.youtube.com/watch?v=lyT3eKhSFjw) podcast with Steve Hendricks, author of The Oldest Cure In The World, where he talked about studies that show it's better to eat...
Apologies, I'm pretty sure you get enough questions like this as it was. I used to water fast and lost 30lbs in a short period of time when I lived overseas, now that the pandemic ruined a lot of those...
Due to my social life and work, I am thinking of breaking up the fasting period into 2 windows. Eat from 8am-11am and 8pm to 11pm. That's just cumulatively 6 hours of eating window, shorter than the typical 16:8 breakdown....
Hi everyone! It’s my first post here, and I am hoping you can help me out. First a little background I’m a relatively healthy woman, though now overweight, and I am no stranger to fasting,...

I'm looking for input from folks who practice intermittent fasting and weight training. I typically lift weights in the afternoon around 3pm. On days when I lift weights (fasted), I break my fast with a post-workout protein shake (whey powder,...
Say if I do a 4 day water fast. Then eat normally for 2 days, and follow that with another 3 day water fast. Is that the same as doing a straight 7 day fast?
I've read the obesity code and the ultimate guide to fasting. I know as long as you lift heavy 3 days per week while fasting you won't lose muscle mass. My question is can you gain muscle while doing a long fast....
I just tried my first multi day fast. I guess OMAD is kinda 24, so every other day is 48, and every third day is 72. I ate because I worried about my (low) electro lytes and this was my...
