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

How was your relationship with food before you started? Mine has been improving as I do 24-36 hour fasts, but I definitely have a long way to go before I can say I have a healthy relationship with food.
Back in september 2018, I discovered your channel, and followed your intermittent fasting tips. I was at 110kg at that time, with fast alone I was able to lose 30kg in a year with little training. To this day I'm still doing it, it allows me to control my weight, when I can't exercise for long periods, and I don't have to think about what I eat. It also helps my wallet too.
Yeah I'm fasting now because of inflation. One meal a day but body is feeling great and so is my wallet!

I'm on day 4 of a 5 day fast and I can honestly say the only negative effect I've experienced aside from hunger is heart palpitations. On a positive note I've lost 9 lbs, my mental clarity has increased and I feel like I'm in a better mood!
If liquids are included in your fast, try maintaining your electrolyte balance with calcium, magnesium, potassium and salt (a little coconut water with a half pinch of himalayan salt, 1tsp acv and a pinch of cream of tartar). A lack or imbalance of these minerals can result in a range of issues including heart palpitations during fasting.
Pay attention to your heart!! I had the worst heart palpitations for a long time until I realized I had a vitamin d deficiency .. it all went away once I started d supplements 🙂
For me I get really bad headaches l by day 2-3 abd can’t go longer
Yeah not eating for 5 days isn't healthy.. I don't care what anyone says.
OMG... How do you guys go 4-5 days without eating. I can't even 😭
I'm eating once a week total now. I'm fat so think my body is feeding its self. Drinking loads of water. I don't feel hungry at all. It's getting harder and harder to get my self to eat. Am I really doing myself damage.
However my memory and retention for information has increased so much that i can do my job far better because I don't forget anything. All it took was me to stop eating. I wish I had done this through school I wouldn't have left without an education.

@@thatvampirelorraine This is because your body is addicted to carbohydrates and you eat constantly which is terrible because it spikes insulin constantly. Our bodies are supposed to switch to burning fat for energy very efficiently when not eating for an extended period of time.

@@thatvampirelorraine Okay Boomer
I’ve been working out 2 years. IF worked it down to 23/1. I’m currently on day 3 of a water fast. Aiming for a week. It’s def easier than I thought. It’s all in your head.
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.
I don’t do a typical fast with an eating window. I tend to not want to eat before 8 hr intervals.
Wait 8 hours to eat 🤣, at night I would be okay, but in the day my body needs food every 4 hours or I get shaky/trembling, dizzy, nauseous and faint !

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.
the boost in energy is MUCH higher than that you might get from caffene or some other sources.
I’ve been fasting for two months. Lost 50 pounds and I have so much energy now. And I don’t feel hungry at all. I have 100 more pounds to lose. I’ve been making sure to watch my electrolyte intake.

@@Voltomess A guy fasted for a whole year under medical supervision, so it is very possible. That’s the whole point of stored fat. It keeps you alive while you can’t eat. Of course, you need to make sure you take vitamins and drink enough electrolytes daily like sodium and potassium.

16/8 I think is the most reasonable. I started at 217 a week ago. I got on the scale today (which I said to myself I would not), because I feel it in my clothes (down a size). I'm 203.5. 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!!!

Just postponing the breakfast during weekends a couple of hours feels good, and I have lost weight. I've never been overweight though. I have also reduced the number of meals / snacks during the weekends by one, making it a very light form of intermittent fasting. 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. Knowing what's bad for your health, effectively precludes such consumption. But I do allow myself goodies, such as desserts sometimes; but always make sure to enjoy these in conjunction with a meal, not as a snack in between.

Im doing intermittent fasting for weight loss and health benefits. Although there is a little bit of cheating with sugary drinks like tea and coffee, I'm sticking to it pretty well for the most part. I found that I only get hungry during the final hour of a 16 hour fast, which makes sense because my body knows I'm going to eat soon. I haven't been doing it for very long, but I've noticed I'm losing 1-2 lbs a week, even with the cheating.

If your goal is to lose body fat sustainably you should try cutting out insulin-spiking foods, up front processed stuff that is full with sugars and other refined carbs. But also bread, pasta and starchy stuff which contains little dietary fibre.
Nobody *needs* to eat that stuff.
The less you spike your insulin levels during your eating window the less hungry you feel during the fast.
As a dietetic intern, I felt you covered the topic very thoroughly! The only thought that came to mind during your video was the different rates of when specific metabolic pathways are used in different conditions. For example, ketosis is less preferred during times of metabolic stress, so muscle breakdown will occur at an increased rate. Just to clarify, all of these forms of metabolism and catabolism are being used all the time; the conditions of the rate is what changes.
can you gimme advice whats the best approach to fasting as someone who eats everyday ? i imagine going full cold turkey 7days fasting could be quite damaging..

@Rodrigo Herrera Hi Rodrigo! I very much would like to hear more (or read more, so to say).

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.
you did weight training during ur fasting? Wudnt that make you loose mass because your not eating after lifting weigjts becauae how are muscles supposed to heal and grow with no food input? I know you mentioned hgh is released but does it really ?and is it enough to maintain? How much weight and mass did u loose? i wana fast but am already slim been working out to build size n be bigger but wont fasting reverse this hard work haha
@@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.
Wow really amazing!
I have competed in drug free powerlifting ADFPA 1988-1991) and done 40, 28, 25, and 23 day water fasts where I only drank a little black coffee besides water.
However I didn't lift weights at all during those fasts let alone max squat and deadlift.
Wow!

Electrolytes are just sugar. Sugar water and up the you go. Adding a little salt as well I guess. Need that iodine.
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.
I'm on keto diet and also one meal a day. As I write this comment, I've been on a complete fast for the last 150hrs. I plan to break my fast 2moro
Before I started this keto lifestyle, my weight was 110kgs, now I am 74.3 kgs. Keto and fasting has completely changed me
I really enjoy intermittent fasting. Due to not being able to run like I would like to, I was still able to drop 30lbs over the past few months at a nice steady pace and I got back down to my weight I was in the army without running and I look better since I am not running as much, so when I do introduce running again I know not to over do it. Great video
In order to implement running I suggest fasted cardio with strength training to keep your figure good. Like 2 times training or Weights first Cardio after with Running.
Good job! I am lazy and really don't like working out hard. So to stay not fat I just don't eat carbs much and intermittent fast most days. I lost 50 lbs last year and have been maintaining a good weight ever since.
I did try 2 day dry fasting and trust me this is amazing experience for anyone especially with diabetes or heavy overweight
I did last year 14 days fasting. Just water, salt and some vitamins. In the last 5 days i needed to add a bit of squeezed lemon in hot water in order to balance the PH of my stomach (that was getting too alkaline from the salt and the vitamins). In the weeks after this fast is remember having a drinking session with my friends, the next day everyone was in a massive hangover apart from me...my liver and kidneys really detoxified.
if you have a balance food and life style , you do not need to torture yourself for 14 days to reset your metabolism , usual you need 40 days to reset , but your brain will never ever forget this for you , you can't do this cold turkie and remember there is no such a thing as detox - it is all BS
@@skhochay fasting is not torturing yourself
@@klddere3734 it is the same consequences as quitting heroin it is not you body it is your brain needs to reset the process and like I said it will never forgive you for that, you have to do gradually slow you have to train, I have seen people that quit eating lost 60lb in 1 month then in 2 weeks they gain back 100lb and got themselves in all type of medical problems.
@@klddere3734 what hes saying is that its better to ease your body into the long fast by doing small fasts before
@@skhochay Now you are just lying. You have never seen someone gain 100 lbs in two weeks.
Been fasting for two days a week now. As a chef I eat constantly at work. Two days off is just what my body needs to burn excess fat and normalize. Drinking cold water helps to shrink your stomach so when you do eat again. You won’t gorge yourself and have a massive colon blockage. Feels incredible!
I would think drinking very cold water would ramp up the metabolism too.
You just surprised me by saying drink cold water?
just constantly drink water and then when you eat again you wont have much room. it's not easy to over-hydrate when you're overweight. don't buy these myths that you instantly get a sodium deficiency the second you drink too much water. you would need to be eating 0 processed foods and you never would have had a weight problem if you were doing that
I have started fasting only on the water for the first time in my life, and I'm 25 years old.
It's my third day and stumbled on this video. Thank you very much for it. Now, I have more motivation to keep it up; I'm not overweight. I just want to say no to myself sometimes... anyways thanks again, and guys wish me luck. I set a 7-day goal, but I might go even longer now...
But the video said positive effects up to 72 hours and then negative effects begin thereafter....
Dont do this! You'll lose the essential nutrients and minerals and then your body will burn muscles.
@skibumfajita I'm drinking 1 cup of tea with 1 square sugar for glucose
Don't exaggerate. I for myself had a only water diet from Sunday evening to Monday evening for the last 9 months. I did it for multiple reasons. One of them was to make sure to prevent the organs to grease over time.
I think it is healthier to do it for no longer than 2 days but more often maybe every 2 weeks. My weight hasn't changed at all but that isn't needed at all with 143 lbs.
For mondays I will go running instead now to build up muscles and endurance
@@AM-wg7qv na fasting is fine look at people who fast in Ramadan. It is extremely beneficial
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.
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.
Sheesh your crazy and strong man

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! 😊
Thank you for sharing. Inspiring!

In terms of body composition, intermittent fasting is great for those with busy schedules or to reduce meal frequency to lower kcal intake. Even the growth hormone increases are transient, not enough to have any significant effects.
Your body starts to repair itself using the cholesterol that your body provides your prostate will repair itself as well fasting is the best way to repair a body😊😊😊❤❤

Just look at the damn food pyramid-what a joke.
This is one of the most concise videos Ive ever seen.
I’ve started intermittent fasting for the last few months and have lost about 10 lbs. I eat healthy but allow myself cravings in moderation. Ever since I’ve started fasting, I get full faster. I’ve also started taking a daily probiotic for over a year now and that also contributed to me being less bloated.
Edit. I forgot to mention that I run at least 4-5x a week.
What kind of probiotic please suggest so we can take it
Hi, what is the probiotic you consumed? And may I know if probiotic can make us less bloated? thanks

@@diegomunoz2695 different from person to person. Doctor that specializes in diet or a registered dietitian consult could help you figure that out.

Most Americans could probably fast for a week and still be burning stored fat.
The optimal fast for most people is 72-100 hours.
I have done many fasts in that time range and I always come away feeling so much stronger; physically and mentally
Table spoon of apple cider vinegar in a large glass of water will keep you full for a while if you feel hungry. I do 18/6 - 20/4 Mon-Fri.
So much more energy and combined with weights/exercise I feel like a champ! Been doing it for months now.

This video has such a negative undertone. I’m on a 90 day water fast. And I take a few vitamins and a lot of sea moss daily and I’m doing fine . I think anyone watching this video needs to do more research other watching this video and thinking it oh so dangerous! My mind has changed so much on how I’m going to eat after my fast is over. I’m 32 years old I want to live a healthy lifestyle and I’m happy reseting my mind & body doing fasting. I’ve done 1 year of working out & intermittent fasting & lost over 30 lbs. that was great. I’m trying something different this time and I feel abundantly confident in this choice.
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.
Trousers, pants live under the trousers
do you have a link to this process.?
@@JerryDunhamJr There's no link. I just decided to try alternate day fasting last October and have continued to this very day. Last October I weighed 235lbs, however I'm currently 182lbs. I only eat between 12pm-6pm on alternate days and then won't eat for another 42 hours. I only drink mineral water with a slice of lemon when I'm not eating for 42 hours. My BMI has dropped from 29.1% body fat (almost obese) to 22.3% (healthy weight) in just over 5 months. I can now see the outline of my abs for the first time in my life. It's not a long process but a difficult one and very much possible if you have the willpower and determination. I'm aiming to get my BMI down to 14% by October, which would leave me with a six pack! 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.
@hardstyle905 eat a lot of really good food during your eating window and do compound movements for your training.
UA-cam has suggested I try and watch something out of my comfort zone and I clicked the link. It brought me here. Ironically this video is pretty much what i needed to see. I'm contemplating on extending Ramadan for myself in an effort to try and lose weight. I found this info to be very informative. Thank you for sharing!
1. I’ve found that intelligent, well-structured, prolonged fasting beyond 36 hours has proven to provide even greater health benefits.
2. I’m personally doing 60/12 PF, Paleo.
3. 6 am - 6 pm on feeding days.
4. Feeling fantastic, losing weight & mental clarity much improved.
5. I’m “fat-adapted”, so I never experience hunger before the 60 hours are up.
6. During the 12 hours of feeding, I allow certain carbs toward the end of my feeding cycle.
I had that Problem for a few Years. I was chubby most time of my Childhood and as a Teenager. I started loosing weight when i was like 19. Jogged a lot and worked more practical. And suddenly i didn't eat much. I just sorta lost interest. I had like one Slice of Bread with Jam in the Morning and covered my Appetite up with lots of black Coffe until evening. Then i might had some Chicken and Salad. I lost 60 Pounds within half a year and i was skinny as heck. People walked to me and said i was looking bad. Pale and unhealthy. Never found Balance in that. Nowadays i wouldn't say i'm chubby, but i'm defenetly not slim...
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.
Thank you for sharing the story. 💜 May you heal and build strength; mentally and physically.
as someone with an ed too; i’m currently in quasi-recovery. i’m on the verge of a relapse, but i’m glad you’ve come out the other side. i’ve been this way for years and it probably won’t get better but it’s always nice to see people who it did get better for. thank you for spreading your positivity
@@babykillingcadillac6719 I had a borderline ED when I was meticulously working out to lose weight. When you realize it takes an hour to burn 200 calories, throwing up that huge meal and not having to work it off seems mighty tempting.
I would water fast for 3 weeks then I’ll eat by the calories to be careful. Drink a lot of different liquids to get you through the day.
I heard somewhere that the prophet Muhammed used to fast two days a week. I might try it for 6 months beginning in april (1 week from now). Ill also be rejoining the gym from tomorrow evening and going 3 times a week (its been two years of no exercise and terrible diet, ive gained 37lbs). I'll post results here every month to share my experience.
I started fasting 16/8 and then 20/4. I am 1.82 m and I was 90 kg now I am 80 kg. I had some liver problems because I had entered a period of loading with all kinds of fats and sugars. Now for 7 days I keep fasting 3-4 days. I only drink organic black coffee, I don't drink juices of any kind, without white bread (it contains starch so sugar) and water which is the most important. I eat an apple almost every day (it greatly helps digestion and intestinal transit). I do push-ups almost every day and I have a very good muscle tone and I walk a lot. I feel great now, so I think fasting is number 1 for a healthy life because it allows the stimulus to feed on unhealthy fats and the cells to regenerate.
Ive done intermitent fasting and it benefits me a lot
Was having a hard time deciding if I should continue my fast of having just one single meal per day consisting of little amounts of food in the morning and starving myself for the next 23.5 hours (in order to speed-lose weight & look skinny), or to heed my sister’s advice and still maintain a diet of 2-3 meals per day (just that it is much healthier than what I usually eat). This video finally convinced me to give up on speed-fat-loss and aim for a more effective weight & fat-loss journey on the long term instead.
Gonna have tons of veggies & protein for dinner later lol
I have done long fasts several times, and the results have always been beneficial. Right now I'm on Day 17 of my current fast, lost about a pound a day, and feel great, think well, and generally experience no weakness. As for hunger, it is largely a transient sensation, so that if I don't dwell on it, I don't stay hungry. I am planning to go about another week, and when I break my fast, which is really the only perilous part of the process if you overeat, I will be doing it with an Ethiopian Vegetarian combo, the best food in the world. I think the modest estimate of 3 days fasting before it becomes harmful is just ridiculous. I have at least another 10 pounds I can lose before I see any muscle under my little pouch. Right now I am 160 lbs, and have hardly lost more than an inch off my waist. I may stop at 150, maybe.
I agree with almost everything you’ve stated here, but the statement that your brain will only use glucose is contradictory to many other experts opinions that in fact the brain prefers ketones for fuel over glucose… can you elaborate on this please?
> experts opinions
What? LOL
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.
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).
@@theothersideofthecoin3125 thanks, I wonder why so many “experts” (including Dr. Berg) say that ketones are what the brain prefers?
@@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.
42yo dude and have dropped 30lbs in the past couple months with intermittent fasting. It's completely reversed my Crohn's and ADHD symptoms as well. Can't recommend fasting enough. 3 days is definitely the sweet spot.
3 days fasting eased your ADHD symptoms? May I ask which ones?
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. Interestingly the scientific papers he refers to suggest that the body will consume body fat before it starts to consume muscle mass. 3 days of fasting for me at least only produces water weight loss on the scales which goes straight back on again when you resume eating. 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.
Me too I feel like I’m doing something wrong
The average modern human has plenty of fat to fast for a very long time. Muscle is expensive, the body won't scavenge it until it must.
calories in calories out, one day of fasting followed by eating at your maintenance calories will still lead to fat loss. it doesnt need to be longer than 3 days
i read some other studies, say fat burning will rise after the 3rd day and after that muscle will significantly decrease after 7th day ish
thus they suggest 3-7 day fasting, for no more than twice a year ish. however, same goal can be achieved by practicing 168, 186, 204 diet
@@keepitprivate3856 thats wrong. dont believe it just because it was "some study".
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?
if you are taking vitamins and minerals you are probably breaking a true fast
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.

Just eat when you are really hungry. Bonus not mentioned here : everything taste SO GOOD when you do eat.
Great video. Sorry for people going through hunger. By the way beside the behaviour improvement goal, Allah prescribed Ramadan fasting for health benefits. Seen on articles you've shown
I have type 2 diabetes and started fasting intermittently every second day, where all I took was a couple of eggs, avacado, an orange and water in the morning, along with Metformin and a vitamin and mineral tablet. I went from 106 kg to 88 kg in a couple of months and am now looking to get down to about 77 to 79 kg and stay there. I'm 183 cm tall and 34 years old. Fasting is really good for weightloss and health in general. There's also a new drug developed in Denmark that's called Ozempic, that works by blocking the protein that makes us feel hunger. This is mainly a diabetic medicine, but can also be used as a way to make fasting easier.

I thoroughly enjoyed the graphics in this video. and of course the content too. Thank you! Well done.
I officially fasted. For A Week!!! Weighing 216 pounds, I knew I would lose weight faster than others but I didn’t expect these results. First of all, I started on a Sunday which is why I’m saying this on a Saturday and crazy stuff happened. I’m always searching this stuff but literally no one has tried this, I’ve only seen stuff on fasting but studies only get technical and say people will give up in a matter of days so they don’t elaborate on it anymore, which sucks because I wanted to know beyond the point of giving up. And others just fake their fasting. So let me tell you what I did. First of all I fasted by not eating a single thing. Only drinking water, and a cup of brisk every time I felt hungry. I bought a 3 liter bottle of brisk since that is all I would trick my body into “consuming” but only allowed myself to drink a cup per day. On Sunday I started off great, didn’t even care. I drank my cup of brisk at night went to sleep and it was easy. Monday came and i started contemplating what to eat. But I stopped myself. I drank my first cup and played video games for hours to distract myself until the day ended. I took naps also and just did whatever to have time pass by. Tuesday I woke up starving with a dry mouth. I felt weak but didn’t care because I expected it. The whole day I spent slouching, being lazy, and not having the energy to do anything or put thought into anything. But I never slept. I couldn’t do anything I enjoyed and was so emotional towards the end of the day. Night came and I was so tired from not sleeping or napping all day that I knocked out. Wednesday comes and something happened I never knew could ever happen. MY BODY SWEAT A TOTAL OF 9 POUNDS!!! I fell asleep and kept waking up for minutes only to fall asleep again for 14 hours straight from 12am - 2pm of Wednesday. I went to sleep 115 pounds and weighed 106 pounds when I woke up! I told everybody I knew but they didn’t think much of it. I showed them my proof and everything yet no one seemed to care. They just kept telling me not to starve myself and eat. But I didn’t want to, I hate not fitting in my clothes so I brushed it off my shoulders. I went to my room and drank my cup of brisk. I did research and you can too if you don’t believe me, studies have proven that people have gone to sleep and have lost a total of 1-7 pounds of water weight. I know it’s water weight and not much will think of it but that’s a huge significance for me in my weight. So I go to sleep at the end of the day and then weirder stuff starts happening the next day. I wake up earlier than usual, I keep sweating but now my body can’t rest. I woke up at 6am and couldn’t sleep for the rest of the day. My body felt so unproductive but not having enough energy I didn’t bother to look for food. I stayed in bed ALL DAY. I was just thinking constantly, looking at the mirror constantly just to see even the slightest of change or improvement. Even trying on outfits and seeing how I fit in them now compared to before. I went to sleep Thursday weighing 104 pounds devastated. I woke up early and sweating still. Now stuff started getting technical. I realized I never drank my cup of brisk and drank two. I weighed my self and saw I was 105! I hated myself. I realized now every ounce of water or brisk I drink I will be able to see on the scale no matter what. I hated myself. I thought I lost progress and thought of a solution. I kept taking naps, doing whatever I could to sleep no matter what. Constantly the thought of self hatred and sleep motivated me to. Hours and hours of naps, Only resolved to one thing I knew would happen. I’m a heavy sweater and maybe it’s due to my weight. So when I sleep I sweat a lot, I woke up very late and weighed my self. It’s now Saturday Morning, 3:52 am and I weight 199.2 POUNDS!!!!! I can’t believe it man. I went to the first video of fasting which is this one and told my story as the video went on. I’m going to be fasting for a month, it feels like hell but I won’t allow myself to go above 200 Pounds ever again. I’ve weighed over 200 pounds for 4 years now! Never again. I’m telling this to people who want to know the results but can’t find them anywhere. I’m going to copy and paste thing comment so I can post it on comments of other videos that might resemble this one for anyone interested. I’m willing to answer to any comments whenever I’m available. Wish me luck, and good luck on fasting!
Use some stimulants to help you though your fast!
Tell how its going brah
It’s almost another week soon and I have big updates for anyone interested. See y’all Saturday
@@Art_ticous take vitamin pills so you dont die
I weigh 182 now, and I’m at such a weak point. My memory is barely functional at remembering and I sleep all the time. I feel so fragile, but im mostly in a good mood. I think im going to stop now. I’ll try to later this month, I can’t even think straight right now. Next week I’ll restart the process, I want to get to 150 but I should eat now. I’ve played hours of UA-cam videos and can’t remember a single one. I literally play hour long videos to go to sleep. I’ll eat for a week then continue my fasting next Saturday.
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.
I've been trying to eat less, I haven't been starving myself, but one trick I've learned is to keep a rubber band on your wrist, ping yourself with it every time you take a bite of something unhealthy, that changes food from something you do for comfort, to something painful, a side effect is that you will want to take bigger bites and chew them longer, and you'll want to eat healthier things to avoid being pinged.
i do a 24, 36, or 48 hour fast ones a week and i love it!
The first few days are tough, but I love the 4th day of fasting when my body reaches ketosis. I wake up feeling like a lion. All my senses are heightened. Sight, hearing, smell, taste, reflexes and brain function. We may have forgotten, but our bodies remember we're apex predators.
THIS is the good shit! No one really talks about it but after the third day....dude. It is like you are seeing beyond. You feel like a wolf; all senses clean. Your frame rate increases as more information is able to be processed by the brain knowing the body needs energy. You can hear gnats fuck a quarter of a mile away and count every pebble in the road as you are driving.
On the fifth day, if there was a couple of Navy Seals standing between me and a bowl of rice....I'm getting that rice.
@@ananda_miaoyin 🤣🤣🤣🤣👍🏽nice one mate
Not me. I am so full of toxins, it will take several fasting cycles before I feel good after 3 or 4 days. I did 28 days once, and by the end of the third week, I felt incredible nonstop nausea. It was great.
@@dangerouswomenseries My guess is you're cheating and are never truly reaching ketosis then. You're somehow getting sugar and carbs in your diet while you fast, or you have some other underlying health issue.. Some people won't even brush their teeth, in fear the sugars in tooth paste will kick them out of ketosis. Remember, even one cookie and you have to start all over. You're only cheating yourself.
And honestly, it's not healthy to fast that long. Your body needs the electrolytes and minerals for proper function. Done improperly you can cause severe liver, kidney and neurological damage. fasting should be done as a system reset, followed by a healthy balanced diet.
@@ananda_miaoyin damn that last part had me laughing like crazy 🤣
the extreme muscle loss has been objectively debunked - the body protects its muscle
One thing I’ll say on malnutrition, I’ve done a metabolic panel and a CBC blood test at day 5 of a fast and then day 18 or 19 of a 21 day fast and my lab values looked great. The only major changes were A1c which lowered from 6.1 to 5.1.
How much did you weight at the start of your fast?
You reversed your diabetes ???
6.1 is a dangerous i.e pre-statge of diabetice where as 5.1 is good and in safer zone so, A1c is aslo in positive direction...
I just did this over the course of like 6 months. Can say it works as stated. I lost like 40 pounds. I don't remember the feeling of hunger, though that might be because I was a shift worker for a good time, and couldn't eat for prolonged periods of time while I worked. I'm kind of stabilizing on this diet, but that's kind of annoying because I'm still slightly overweight like a pound or two.
Like wow.
the most scary thing about not eating for a long time is that yes u lose hunger after a while but !! it will get harder to eat something as soon as your able to.
very well researched and presented imo . Ive been a couple of days here and there for 4 years now (originally for ankle inflammation which reduced considerably ) and everything this guy says is spot-on.
Hi Noah ❤️
Fasting is extremely important, I been doing OMAD almost every day and I have lost 30kg since October 2021 tilll now that's about in 4 months period. I also integrated walking everyday atleast 11k steps everyday I mean everyday haven't miss a day since October, also 5 to 7 days a week at the gym. But overall I think fasting played the biggest role, about 70 %
Got into keto and OMAD and had a part time job on my feet, lost 75 pounds in 7 months. I also believe fasting was the primary driver in the fat loss (keto mostly helped me stay on schedule).
at what time do you eat sir for the omad, can it actually help in the beginning with lots of cravings and what not
@@adeqnjw7362 you generally pick a time that works for you. When I first tried I tried I ate between 10 a.m. and 2 p.m. but 4 p.m. to 8 p.m. worked better for my schedule.
At the beginning you'll definitely need to exercise some willpower but it does get easier. Keto works well with OMAD because you eat more fats/proteins and those are more filling and you stay satiated for longer.
@@maraudentium2607 why did you choose keto?
@@Alex-mg5he it made more sense to me than other diets and the food looked better.
The body will burn fat on its own for "fuel" but of you're supplying your body with carbs/sugar it's going to burn that first rather than the fat on your body you want to get rid of.
There was a lot of talk about the "roller coaster" feeling when eating sugar/carbs (you eat in the morning, feel good, crash, eat again, feel good, crash, and repeat.
All the benefits (higher energy levels, improved mental clarity, etc...) countered the things I was struggling with (low energy, general brain fog, etc...)
The diet is limiting but it's still rather simple and contains a lot of foods I really enjoy...almost went with Paleo but didn't want to pass on cheese. My go to meal is a few skin on chicken thighs and roasted broccoli and I love it every time.
Keto and OMAD for me. I Workout fasted and feel amazing. The first week is hard but after that it gets much easier. Getting more muscular and shedding body fat fast. If I feel hungry I add a pinch of pink Himalayan salt to a glass of water and my cravings are gone, also I have a cup or two of organic black coffee a day and a table spoon of ACV with water at night. I only eat grassfed meats, organic pasture raised eggs, and only cook in organic grassfed ghee. For cheese I choose goat cheese. I also eat spinach and avocados.. I stay away from all processed foods and drink plenty of water.
personal trainers should see this videos because they all say the opposite. “ eat small portions 5 times a day” .
Me: “ok … forget “
i have lost a average of 18.8 lbs since dec 2020 .That day i weighed 585 lbs today i weighed 245 lbs . 42/6 intermittant fasting and pa;io diet. went from 11.6 A1c to 4.3
Years ago when I first heard of gravity transformation I thought it was just a bodybuilding and fitness subscription but recently I’ve been seeing a lot of videos in my feed and I enjoy watching and learning from them because it has helped me to view gravity transformation in a different light especially since the science behind the body and its functions is explained. It makes me see that it’s not just about fitness subscription but instead shows me that you know what you’re talking about and that it can be done no matter your body type.
I stopped eating real food for about a month I ate 3 small bags of chips every day and drink water about 600 calories a day . Then I begin to eat real food again, and felt really sick for awhile until my body got used to the nutritions again… don’t do it be careful it can be deadly
I try to do 48 hours each month, since September, feel great. Thanks for the explanation,
Be careful what you eat coming off a fast, start small, like 1 egg, or an avocado.
⬆️Not a Dr.👍
Bro what is fasting and after fasting what food we have to take
@@hanifamishfaq4902 Gravity Transformation has made videos on Intermittent fasting. Check Them out
@@hanifamishfaq4902 you are in a vide about fasting xd just dont eat for 48 hs and dont take carbs to finish the fast, just eat proteins and fat
During ramzan muslim fast for 1 month Do breakfast before sunrise and then fast for whole day without eating and drinking and then eat food when sun is going to set (magrib) and they feel healthy doing this because they eat roti on morning that full of carb and other nutrition and on evening they eat anything that give them more energy and fasting makes their body clean inside even i am witness of it. It's 10 days of fasting still did not feeling any deficiency and feeling my body more than ever ✨️ MashAllah ❤
Good video, but I disagree with a few things:
2:29 "Liver glycogen is depleted in 24 to 48 hours." That is unfortunately not always true for very metabolically sick people. Dr. Fung reported that he had a patient who could not achieve Nutritional Ketosis (the primary sign of liver glycogen depletion) after two full weeks of full water fasting. Dr. Atkins reported similar results. His diet's 20g carb "Induction" phase, which mimics full fasting, still left about 2% of his patients not yet achieving Nutritional Ketosis within two weeks.
4:18 "Your brain primarily relies on glucose to function." This is true for people who eat a carb based diet. However, once adopting a ketogenic diet with low carbs, your brain is quite content relying "primarily" on ketone bodies, with around 120g (approx.) (est.) of carbs a day for brain and red blood cell functions. Gluconeogenesis is not a "temporary" process.
4:43 Fasting consumes some of your body's stores of protein within your Lean Body Mass. This is much more than just "muscle." In fact, the discussion of Autophagy later in the video describes the beneficial effect of recycling some of these old/damaged proteins (amino acids) throughout your body, without impacting your desired muscle mass.
6:15 "Muscle loss shouldn't be as big of an issue until about 72 hours after beginning a fast." I agree, however the fasting process really "should" include the refeeding phase as well. Refeeding leads to the inverse rapid increase in lean body mass and indeed muscle, perhaps better than before starting the fast.
6:45 "Muscle loss can start happening sooner than three days if you are already lean." True, but hard to quantify, I'd definitely agree with "Lean Body Mass will start happening sooner than three days for everybody." If your body starts out at 50% water and ends up at 50% water, than 50% of your fasting weight loss will have been water. There is some water in fat cells / adipose tissue, however most of your body water is contained in your "Lean Body Mass" segment. Overall, I agree with the warning that extended fasting is more dangerous for lean people as opposed to overweight and obese people.
7:14 "At least 2/3 of that weight loss was muscle loss." That is not what the poorly written results said, as fat-free mass is not the same as muscle. I would like to see this entire study, not just the abstract.
10:40 In starvation, you will "most likely die from organ failure." Not exactly true. You will most likely die from the loss of muscle mass/strength in your diagphragm, which will likely then be classified as heart failure.
As someone who is studying the body, if you want to get into the minute details then yes; his videos aren't going to describe the exact science behind everything. However, everything he said is correct for the general population, and explained in layman's terms because the majority of his audience isn't going to understand the technicalities. Looking through your "disagreements" you start them by either saying "true", "not exactly", "I agree", "not always true". Even you understand that he is mostly correct and creating comments like this is only going to deter people from his videos because they are now going to think he's lying or being dishonest when in reality it's just you nitpicking extremely irrelevant anecdotes and intricacies that no one understands. I understand where you're coming from, but unless he says something completely wrong, comments like this; while well-intentioned, only scare people and damage their perception of this channel. While they don't get everything correct down to the atom, they provide extremely comprehensive information in well-made and entertaining videos to help the general public, don't do them a disservice.
@@massimopascuzzi8870 Interesting observation. I don't think that it is true that my comment will impact anyone's view of his channel, however.
Out of curiosity, can you please make a video explaining where fluid goes while going from your stomach to you bladder?
ADF is wonderful 😊I do this way of fasting. Im 44 and 510. I love the way my body feels and my energy levels❤
Clean eating is also an important element.Healthy foods Are also needed.👍💙
Really simple explanation. Very cool.
You should do a video on how this can be beneficial for muscle growth, given the right eating window and nutrition.
Excellent video. I have been partial fasting for around 4 months. I eat very little, 2 times a day and go the remaining 16 hours without food, just water. I'm gonna start fasting for entire days after this video, not going more than 3 days. Thank you for the information.
What was the benefits of fasting on your body. And how you manage it.
2 times a day it's not a sacrifice. Good luck for your fasting
I have been doing IF intermittently for the past several months with reducing sugar intake significantly, more greens, more protein, and less carb. While my weight does not loosen as fast as I expected, I noticed my mental ability increased. I am more focus at work and so far does not experience daylight fatigue. Since I am lazy to workout (except some squat and lifting weights at home) doing IF is my only salvation for now. I occasionally take multivitamin. I start IF at 7pm or 8pm and until 11am or 12noon the next day. I only drink black coffee zero sugar with a pinch of salt in it. For dinner, either two almost riped banana (with greenish on it) or full meal (depending on my mood). Occasionally during noon, I do eat some tidbits.
You already fast while you're sleeping. Just don't eat while you're at work, factor in the hour or so it takes to get home or get ready for work, and you've already got an 18/6 fast without even trying.
How do you avoid temptation of snacking during office hours?? Am I the only one who grab snacks every 2 hours for enjoyment lol? ( I’m not hungry, but snacking on nuts is so addictive lol)
@@Private_Library2 Maybe stress eating
This is suprisingly in depth. And also checks out with my own personal experiences and knowledge when it comes to fasting. Nice video.
I was diagnosed with Dysphagia & Aspiration in the last three months...I'm not able to eat much, I've lost 65 pounds & I'm very malnourished...been working with my clinic, hospital & Dr to find better ways of getting the nutritionance I'm not longer getting from food...I wear heavy clothing because I don't want people seeing me like this...any advice on this condition would be immensely appreciated
Always watching you and get inspired here from kenya 🇰🇪💯
KENYA RULES!!!
Been living this way for 25 years!!!! Now people are just realizing, funny that all those that criticized me for years are all of a sudden doing the same
I do intermittent fasting-16:8. I’m able to loose weight safely & find I have more energy and ability to focus.
Brb gonna go fasting real quick, reply to this comment in a few days to remind me (not begging, I seriously just want to be reminded)
How have you been?
