It's well known that when you eat your body begins a series of biological processes to digest and use the nutrients found in that food to help you repair muscle, create new cells, and even store some of the extra fuel as fat for later use. But it's not common knowledge that when you don't eat your body enters a completely different series of biological processes that are just as necessary and beneficial as the biological processes that occur after eating. Of course, if you don't eat for long enough the negative effects will start to outweigh the positive effects, but there are definitely myths and misconceptions about exactly what happens to your body when you stop eating, so today I want to go over that process step by step based on the scientific evidence.
And first, let's address the conventional advice which would tell you that it’s unhealthy to go for long periods of time without food. And I don't mean days or weeks, I'm talking about simply skipping meals. On the contrary, we've been told that we should eat small but frequent meals. The truth, however, is that there's nothing “natural” about eating five or six meals, spread out evenly over the hours that you're awake every day. This is because, throughout our evolution, we didn’t always have access to food, so you could claim that a “fasting and feasting” eating cycle is more natural than eating breakfast, lunch, and dinner every day.
Due to the fact that our ancestors had to cope with cycles of food shortage and food abundance, we've developed metabolic pathways that help us cope with prolonged periods without food. In fact, fasting for long periods can actually benefit your health rather than hurt it. But it definitely doesn't feel that way because one of the first things that’ll happen when you stop eating is you’ll start to feel an unpleasant feeling of hunger. Now the intensity of this feeling of hunger highly depends on how accustomed your body is to burning fat for fuel.
You see, most people regularly eat a high-carb diet. So, their body relies primarily on glucose for energy instead of using fatty acids or ketone bodies. Your body has the ability to store a lot of fatty acids in the form of body fat and those fatty acids can be used for energy at a later time when food is scarce by converting the fatty acids into ketone bodies in the liver. But with glucose, it's an entirely different story. Your body can only store a limited amount of glucose in your muscles and liver for future use, and this amount gets depleted after fasting for only about 24 hours but depending on how many carbs you eat regularly it can take as little as 8 hours or up to 48 hours. After that point, your body will have to rely on a different energy source in the form of fat and if your body isn’t effective at burning fat for fuel, this will likely lead to severe cravings especially for high carb foods.
Now, if you’ve trained your body to use fat for fuel by let's say following a low-carb diet, a keto diet or you've gone through long-duration fasting, then you won’t experience the same severity of hunger cravings. In fact, many people that fast frequently don’t experience hunger at all. This isn't only because their body is used to burning fat for fuel, but it's also because hunger levels increase at the times of the day that you normally eat. This is due to the hunger hormone ghrelin, which has the effect of stimulating your appetite when it's released. So during the first 24 hours that someone stops eating studies show that ghrelin will spike automatically for most people around the times of the day that they typically have breakfast, lunch, and dinner (1) and that spike will make you feel hungry. (1)
However, if you're someone that's already become accustomed to fasting every day, you won't experience these sharp spikes in ghrelin during your 16-hour fasting window, meaning you won't feel as hungry as someone that's used to more meals per day. (1) But even if you're used to breakfast, lunch, and dinner the data shows us that the spike in ghrelin is short-lived. if you just ride out the hungry feeling that you get, within about two hours from the initial spike in ghrelin, it should drop back down to normal levels and your appetite will drop down as well.
Regardless after about the first 24 hours your body will burn through your remaining glycogen stores and switch almost entirely over to burning fat for fuel which will slowly lead to weight loss. Since your brain primarily relies on glucose to function your body will be able to separate...

When I was in my 20s I made up a diet called “eat what you want, but only one small thing, and only when VERY HUNGRY”. When I felt pangs I would sip water, tea, or coffee until very hungry, and then would eat what I was in the mood for - an apple, a hamburger without the bun, a salad, a pudding. The first day I ate six times, next day four, normal became two, until at one point I realized I hadn’t eaten for two days because I hadn’t gotten hungry. Several things happened; 1. I found I was in the mood for something different each time and ended up eating a balanced diet. 2. My body really liked only having to digest only one thing at a time and my energy soared. 3. After a couple of days my stomach cavity shrank and I was full from less and less food. 4. I lost my carb addiction and 17 pounds in two months. 5. I found out my sinus congestion was only when I ate red meat. I stopped it for 7 years, and now can eat it a couple of times a week without getting stuffy. 6. I became really aware of what my body said it needed at different points of the day, and I cooperated.

[@kevinrandomly643]

The nasal congestion part is interesting because I've have several surgeries to get rid of my turbinate hypertrophy. I'm taking mental notes.

[@cmwHisArtist]

@@kevinrandomly643 …I had an awful new procedure where they inserted tubes into my sinuses and froze the lining , the idea being that it would die, slough off, and open the passages. The whole time I’m thinking but wait, there must be a cause somehow! As they were pulling the tubes out, I heard a crack, and as I was defrosting, I got a torrential nosebleed and staff started running around and dealing with it. Luckily I’m a good healer. I could breathe for two weeks and then got stuffed up again. They offered to repeat the process but my brain kicked in and I said no thanks. A couple of months later I discovered the diet. 25 years later, I developed an abscess between the top of a molar and my sinus on that side, and needed gum surgery. 15 years later, I lost that tooth and the one next to it. Inflammation is a big factor in swelling, and even now sugar makes me sneeze. Good luck. Don’t let them make too much scar tissue, doesn’t function well.

I found just waiting 8 hours between meals and eating smaller meals including salads has made a significant difference in how I feel and I no longer feel bloated after eating. Ayurvedic philosophy on this says that giving your body time to rest between meals (8 hours between instead of 3-4 hours) allows it to use up the stored energy and drinking liquids during this time will flush your system of waste more efficiently if your body isn't constantly busy trying to digest food. This automatically causes weight loss without any other effort.

It was easy and gave results from the first day; I could feel the metabolism switch. I have however always eaten well; the difference is a reduction of what's not so healthy and also the number of meals by one during weekends. I don't have any cravings at all.

Very informative and confirmed by my doctor. I will be putting myself on a three day fast this year when I run into the inevitable plateau that all dieters face when cutting. The key is to maintain vitamin intake, get as much rest as possible and keep working out to drain those last bits of resilient fat reserves to reach your goal. Then after the fast maintain with a strict but sustainable diet so that you don’t blow all of the progress. Thank you for the great content!

My body is already used to the fasting and sometimes my body stretches the fast for 18 hours. For people who are new to this, I suggest start your fasting in increments by 2 until your body is feeling comfortable. Meaning...start out 6 hr fast for a week, the following week 8 hours and so forth until you have a comfortable fasting plan. Gravity Transformation is awesome..big THANK YOU!!!

Here's what you can expect after a short fasting. I have done these about 10 times total and have ALWAYS had the same results. I am muscular, 193 cm, and close to a little overweight. I allow myself to drink as much water with lemon and tea without sugar as I want during these. Day 1) Difficult because of hunger, especially during evening and night time, no benefits felt other than a small boost of energy. Day 2) Better mood than usual, large boost of energy, almost no feeling of hunger. Mind feels clear. Day 3) GREAT mood and huge increase in desire to interact with people and look for social situations and go out to do something in the evening/night. Huge boost in energy. Pretty much no feeling of hunger. Very clear mind and easy to think. Day 4) Lots of energy and clear mind but some stress and irritation setting in, especially towards the evening and before sleep. Get tired and winded easily when doing intensive physical exercise (in my case, two or so hours of beach volleyball) Day 5) Energy is high, but mood is VERY irritable. Disoriented feeling. Unable to drive properly due to lack of focus. Light to medium headache starting to set in. I have never made it past the middle of day 5 due to the symptoms. Total weight loss would usually be from 102ish kilos to 96.5ish. About half of it would come back in the following week. TLDR: I would highly recommend trying this if you are borderline overweight, or more than that.

I’ve done several extended fasts and lived my life, worked, and worked out hard during every fast. My longest was a 28 day water fast where I only drank water and black coffee in the morning. I did supplement electrolytes which IMO is extremely important for any fast over a day or two, or if you’re on a low carb or no carb diet. I’ve also done a 21 day fast and several 10 and 14 day fasts. On my first 14 day fast, I was lifting super heavy 5-6 days per week since I worked out at a powerlifting gym, and even did squat and deadlift sessions at 90% of my max at day 12/13. It’s not super difficult but it’s important to follow your body’s advise and do it with some research. I’ve had 7 day fasts where I had failed at day 3 or 5 because I had headaches constantly. One other thing I’ll say - growth hormone is increased during extended fasts, most research showing increases starting around day 2-3. To best keep muscle, make sure you lift weights or exercise daily.

[@Minas-Morgul]

@@jjohnson9822 Vitaly is on crack cocaine don't listen to him. During a fast, stored fat can be changed into glucose and than into glycogen which is good for normal activities. This conversion process however is rather slow so if you start doing very heavy lifting around 90% of your max it will absolutely damage your muscles and because you don't have protein intake it will not recover properly. Extremely dumb. If you are already slim you should definitely not fast longer than +-3 days. That way you will get the metabolic advantages but not much of the muscle degeneration. And obviously in those 3 days, don't do heavy exercises cause like I said the energy delivery system from fat is to slow to keep up with the high energy requirement during these types of training.

[@ObsessedAwe]

I often fast, 7 days is my go-to. Five days is also good. I feel like the first 3 days are the hardest and that I only really get to the benefits after 3 days. I also do it for spiritual reasons, but the health benefits are insane and my body craves it sometimes. Sharp focus and actual energy gain as well as weight loss (not my driving factor) are just a few. One of my favorites is a reset on my sleeping pattern and less sleep necessary in general. Where I normally need 8 hours and often wake up groggy, on a fast I would wake up fresh before my alarm after about 6 hours. Truly it is one of the most beneficial and life-changing tools I have had the pleasure to discover. I have never felt like I lost muscle during fasts, so here I would like some more info. I speak under correction, but my understanding is that your body may use proteins (muscle) while it is in a 'reduced caloric' or malnutrition state, i.e. it still uses glucose for energy. As soon as you switch to ketones, your body should stop. (For reference on this see Tim Noakes' first fast vs. his consequent fasts). For that reason I make a point of exercising in the first day or two to burn my glucose stores as fast as possible. I exercise throughout my fasts, usually a bit lighter than normal. We also should not underestimate the mental and emotional effects. It is really good to break bad habits or get out of a rut and become appreciative of the things we have. The only negative effects I have had are heart palpitations and sometimes a little light-headedness from getting up quickly or the like. When my heart pounds I add some salt to my water and it feels like it helps.

Recovering anorexic here I used to be overweight then I started exercising about a year ago when from 170 to 105 in a year I’m 125 and doing better I hope to get back to exercising soon and this time I’ll do it right. A message to other anorexics like me. Stop for a minute take a deep breath and just think about what to you are doing and why you are doing it if it is to be skinny then why do you have to starve your self there are plenty of people who a skinny and eat the two are not mutually exclusive, and the more you starve your self the worse it will get, your body does everything it can to survive the less you eat the slower your metabolism will get and in addition you will start digesting your own body. In short you are killing your self, now I won’t lie recovery is unpleasant at the beginning you will want to stop eating go back to not eating but trust me there is a light at the end of the tunnel and when you reach it you will feel stronger you will be able to concentrate better you will be able to enjoy life without constantly stressing about you appearance at first you will feel fat but you are not you are just bloated because your body is not used to receiving so much food over time the bloating will get less it just takes time. Ultimately it’s up to you but I swear if you choose recovery you won’t regret a single thing.

I'm just over 60 and went on a 21-day prayer fast in January, during which I had no solid food. I had never done more than 7 days before this, but since I'm overall fit and healthy I thought I could do it. I've been on a carnivore diet (meat, fish, eggs, high fat dairy) with intermittent fasting for over two years, only taking limited low glycemic fruits, veg & nuts in the summer season. I found it incredibly easy to maintain the fast. I did, however, continue to take my bullet proof coffee in the morning (waking up has always been hard for me) and took my hormones, vitamin B booster & Omega 3 as usual with it. Since I work long hours and needed a lift by the early afternoons, I'd do another bullet proof coffee around 2pm. In between I'd have mineral water with lemon slices or herbal teas. In the evening I'd do a mug of thin soup, so I could take more supplements...especially the ones prescribed for Covid resistance. ((I chose not to get vaxxed and in spite of having to isolate a number of times due to exposure, I never got sick). I didn't suffer any hunger pains at all and I slept very well throughout, but did get somewhat tired in the last number of days. I lost around 5 kg (which dropped me back into my ideal dress size), my skin looked great and apart from some fatigue - which subsided in the week I started introducing solids again - I feel great. Although the fast was for spiritual and not health reasons, it was interesting to monitor my bodies reaction. I'd love to do a 40-day fast at some point, but I'll wait a few years until I'm no longer in full time employment.

Muscle loss mainly occurs in people that dont exercise while fasting. And by exercise i mean walking will do it. Doing some light exercise prevents most muscle loss in all muscles not only the ones youre excercising. There is also a muscle loss if you are not used to fasting that can happen during the transition to ketosis (using fat as fuel). So a longer fast will loose less muscle weight than many shorter fasts. Hope this helps. But please do your research. Videos like this often leave things out and make mistakes. (and so do comments) For fasts longer than 3 days i suggest supplements.

[@rabbitcreative]

> experts opinions What? LOL

[@Katsem]

I think that was stated in the section where you have lost tons of weight. Your whole metabolism has changed when you are starving. I think you need fat to make ketones.

[@theothersideofthecoin3125]

The brain prefers to use glucose for energy. In fact, in med school there's a famous saying that the brain is 2% of the body weight but uses 20% of the body glucose making it the major consumer of glucose in the body. In a fasted state (in between meals), the choice of energy is still glucose, which the brain gets from glycogen breakdown and gluconeogenesis. However, during starvation (prolonged fasting), the brain can tap into ketones from fat while also trying to get glucose from gluconeogenesis which is absolutely necessary especially since certain tissues can only use glucose as fuel (red blood cells and the lens).

[@raybiondolino9778]

@@theothersideofthecoin3125 thanks, I wonder why so many “experts” (including Dr. Berg) say that ketones are what the brain prefers?

[@andoletube]

@@theothersideofthecoin3125 The main reason for that is the composition of the diet of most people. If the diet is rich in carbs, the brain will use the circulating glucose preferentially because it makes sense to do that. Glucose needs to be metabolised quickly otherwise it builds up in the blood. The brain is able to metabolise glucose very easily, so it does. But if you are on a ketogenic diet, your brain will adapt to ketones and operate primarily on that. The brain only needs a very small amount of glucose to maintain its function. Having done fasting and kept diets myself, I can tell you that I have significantly better focus and creativity when I'm running on ketones. I would estimate that my IQ rises by 10 points on ketones. If people wish to believe that their body needs glucose, it's not based on evidence, it's based on wanting to maintain their relationship with their comfort foods.

I felt really bloated last summer so I decided to go without food and drank only water for 100 hours last August. I found the experience somewhat beneficial even though I really struggled after 72 hours and just about managed to complete the 100 hour fast. I then decided to try alternate day fasting throughout October and have now been doing alternate day fasting for more than four months, only eating between 12pm -6pm and then eating nothing for 42 hours. I've now dropped two pants sizes and lost a total of 40 pounds since October 1st last year. I'm finding alternate day fasting quite natural even though I still have slight hunger pangs between 24-30 hours. However, after 30 hours the hunger subsides and I find it easy to go without food for 42 hours.

I would recommend starting with daily 16/8 intermittent fasting and then increase it to 18/6. However, the goal should be 42/6 which is when you will see amazing results in a relatively short period of time. I also do a daily one hour workout at home and walk 8000 steps six days a week.

Interesting, i have done several 7 day water fasts and one 18 day water fast based on the benefits outlined in your video and that of Dr Jason Fung.

To get real benefit I have to fast longer than 3 days. My experience is the body tends to want to return to its set points and a fair amount of self will is required in ketogenic eating to keep the weight from coming back on.

Longest I went was for 3 weeks. I was aiming for 4, but it was starting to kick my ass at the end of week 2. The greatest benefit from that experience wasn't even the weight loss (I rebounded HARD and none of the loss stuck, and I ballooned past my starting weight later on too) but the realization that you really don't need to eat to live (to a certain point). I was skeptical of people saying eating 3 meals a day was important and how eating once a day is bad for weight (like how?). I also went in after having done 1-2 day fasts sometimes too. And just like this video's conclusion, 1-3 days seem to be the best max time to fast. I wouldn't recommend going any longer even when 3 days is exactly the amount of time needed for the hunger pangs to go away (Once you're past 3 days, you won't feel hungry until a few weeks later). People still don't believe me that I really went three weeks without food because I didn't die. Yeah I still drank water, took vitamins, and salt too. But, I really didn't eat any food whatsoever

Thank you for this video! This may be slightly off topic, but I wanted to share it. As someone who used to be 200 lbs, I find this video very informative! At the end of high school and during my early 20s, I wanted to lose weight and did; HOWEVER, I went about my weight loss the wrong way. It became so drastic to the point where I developed anorexia. I lost weight from the OUTSIDE IN, instead of from the INSIDE OUT. Now, that I’ve become aware of this at 40 years old, I can begin the process of healing and make better decisions. I just want people to know that they CAN lose weight and get healthy, but they have to address the root cause of why they struggle with their weight, in the first place. This video helps me better understand the damage I was doing to my body at the time! There is light at the end of the tunnel! 😊

99% of people are fat because they’re lazy and/or eat poor food choices.

"I lost weight from the OUTSIDE IN, instead of from the INSIDE OUT". Maybe in your mind this is self explanatory. But to normal human beings it is not obvious. I am always curious why people write like this. LOL. Funny

I myself have the opposite problem, when people go without food they obviously feel hunger, I don't feel hunger or thirst ever, as far back as I can remember. So I have to have alarms to tell me to eat and drink. So fasting is not a problem for me.

Making sure I don’t starve to death over 72 hrs no food yesterday I had lots of energy but today I feel so drained out thanks for the help man

[@wiggemach]

You only discussed the negative effects of fasting more than a few days, but didnt mention how well it would work if you took vitamins and minerals during the fast?

[@scroogemcduckrich9705]

if you are taking vitamins and minerals you are probably breaking a true fast

[@zarroth]

works great that way. Lots of channels and doctors talking about it if you do a search. He expressly says it's due to lack of mineral/vitamins when the bad stuff happens. If you supplement you won't have an issue as long as you don't do something silly...like an extended fast when your BMI is already low. If your BMI is already low just exercise, fasting will cause you problems.

That is the way I did it I lost 105 lbs and ate a lot of vitamins. It kept me from getting sick and and kept my energy levels up so could run 5 miles a day during the diet. Worked great.

[@irepairofpc31familykartrac51]

@@scroogemcduckrich9705 I did the keto as well but I’m in my 50s and don’t have a lot of muscle mass. I worked out and ran a lot. I quit drinking after 35 years of drinking daily and it has made a huge impact on my life. Good for you.

When I was a teenager,I became anorexic.I would go days without eating at a time. It definitely impacted my cognition and thought processes during that time.

Thank you, very informative.

[@sativaoryza8648]

I've done this 2 meals / day with 'morning breakfast' and "after dusk dinner" and occassionally if I overslept past 10 am or just dont feel like having morning breakfast, one meal a day (OMAD) with just "after dusk dinner" since 2018 and felt the benefits to my health, eating habits, weight stability and to some extent time saving. In the 1st month you will definitely feel great and deep hunger epecially the early 1st week due to your longtime habits of eating thus affecting your hunger. The rule to my meal is simple, all my snacks are eaten in conjunctions with my meal time, after my meal time is done (1 hr or so) I dont eat aything at all not even a grain of sugar, bread, salt or anything at all just water outside of my meal time.

This is very interesting I didn’t know these facts. Well made and explaining the pros and cons of fasting.

[@MyWebhack]

Amazing video.Thanks for all the effort of making this video

[@sethglenn9022]

When I was a young man I only had time and money to eat once a day or once every other day. Out of pure necessity I learned I had been intermittently fasting. Today I cant stand to eat outside of my feeding window. Going without food all day keeps me alert and energized where eating just makes me sleepy. Since then my record for days without food was about 3 days with an electrolyte drink here and there. I sometimes get hunger pains but can shake it pretty easily. Everyone else around me gets super cranky and lethargic without food.
