I only eat at 9-10 pm once everyday except sunday. On sunday I do not eat anything at all. For 10 months now without exceptions, for 3 years with some exceptions. They have been days I skipped eating because I was not hungry at all. It has been awe inspiring for me. I have heart disease and 3 years ago half of my heart died. We have 3 main arteries pumping blood one of them was completely blocked and they couldnt open it. I was not able to walk 200m without stopping for a minute. After 3 years I run 100m on 13 seconds and at the end I am not breatless at the end. All I did was stop eating all the time and completely quitting sugar. Not 1 gram of carbohydrates enter my body. Now I am able to lift 19lt water bottles with one hand. Fast and cut sugar. Doctors said I wouldnt last 2 years. I am still kicking.

[@stevenx9742]

For a month straight? Or intermittent?

[@Carlawls]

So I've maintained the schedule of only letting myself eat between 3pm to 7pm, giving myself a "cheat day" twice a week. During that time I haven't lost anymore significant weight. Right now sitting around 184 but my frame seems to be shaping up nicely. I haven't added any weight training as of yet, my job keeps me moving and I'm breaking down pallets of goods that weigh between 20 maybe 40 pounds (not doing that all the time). Energy levels still feel good throughout all this. EDIT: And no, I haven't consumed any alcohol. Been dry since last Sept.

With my work (pilot) I travel across multiple timezones every day: it wouldn’t be unusual to go from Paris to Los Angeles, spend 15 hours in LA then fly to Tokyo, spend 24 hours in Tokyo then fly to New York. I find fasting the best way to regulate and manage the huge time zone shifts. As long as I keep an 8 hour eating window it doesn’t really matter what the fasting period is; going west it might be as much as 24 hours, going east it may be as little as 9. But it undoubtedly helps with sleep and evens out my energy levels.

[@goodyeoman4534]

Calisthenics are better for ligament and tendon strength. Heavy weights tax the muscles more and the ligaments can often be playing catch-up, hence why so many weight lifters tear major ligaments.

Any side effects such as light-headedness, mate? Also, did you build up to the 36 hour fast? Fabulous how, exactly? Cheers.

[@iainmillar1532]

I do the same. No light headedness at all. The main barrier is the habit of eating, but it’s really easy once I’ve made the decision. I think the few months I was keto gave me the metabolic flexibility to burn fat easily (if I’d tried it before that I’d have been really hangry). I also find exercise helps suppress any hunger.

[@gtdadof10]

Now, step it up to weekly and you'll really see amazing results (weight loss/control, clarity, energy, reduced inflammation, etc etc) Tuesdays, I stop eating around 630 pm, go to bed by 8 if possible, fast Wed (water with acv, lemon, lime, cayenne, sea salt and coffee with coconut oil, heavy cream, sea salt), don't eat Thurs until late morning. Try it weekly, takes a while but you'll get used to it and feel great knowing you're more healthy

Same. I am 60 and since going Keto and OMAD on Jan 4th of this year I have lost 58 pounds, from 244 to 186. I have not been this weight since I was 19 years old. I started walking 5 to 10K at least every other day and doing weights about 3 days a week. I did not start the exercise until I had lost 20 pounds and already had amazing improvements in every aspect of my health. Stopped BP meds that I had been on for over 10 years. I started the exercise not only because I knew it was good but it was easy because I had SO MUCH ENERGY! Words cannot try day explain how good I feel and how much this has changed my life. I am hooked for life. I had already figured out the changing when you eat bit he talks about here. Today for instance, only the second time in 5 month I have ate 3 meals in one day. I am coming off the OMAD every day and doing IF/OMAD/2 Meals/3 meals and no fasting now because I am approaching my weight goal. I did a couple 72 hour water fasts also. I will couple to do that periodically and once or twice I year do a 7 day water fast. I have maintained a no sugar and only carbs from proper veggies throughout and will continue for life.

You discussed that eating one meal a day increases health regardless of what you are eating. Sumo wrestlers have been doing this for centuries. Basically because you are eating all your calories in a very short period of time, the fat does not collect around heart and in muscle. It basically collects on surface under skin thus reducing the bad effects of being over weight.

[@mikewalkow1860]

Using Sumo Wrestlers as an example of health, now that's funny. And there's no evidence for what you say.

[@Petro00D]

@@mikewalkow1860 Yes, there is evidence. There is a show called the Science of Obesity that played on the Discovery channel. Basically there are two ways in which the body stores fat, visceral fat and subcutaneous fat. When you see a beef steak and see the fat between the meat, that is visceral fat. It is unhealthy because it is in the muscle and also around the heart. Subcutaneous fat is fat stored between the muscle and the skin and does not present the same health issues as visceral fat. Sumo Wrestlers fast all day and consume their calories in around a 4 hour period. Their workout are quite extensive. When they eat their meals, which is a extremely large calorie count(20,000 aprx), the body is unable to quickly store the calories as visceral fat so stores it as subcutaneous fat. I am not a doctor or in the health business so anyone who is please correct me if I am wrong.

Eating early just stimulates my appetite beyond my control. I've tried this so many times. Eating later in the day limits my eating hours .

[@juleslincredule]

Key points: 1. Research into fasting has shown a significant influence on our clock genes, according to a study published in BMC Genomics in 2018. It was observed that the time of day we fast influences more than 367 genes. 2. Other research has shown that fasting prepares the body to receive food, which could explain why people sleep better, respond better to food, and lose weight when they fast. 3. One of the major advances in fasting research is linked to the discovery of the beneficial effects of fasting on brown adipose tissue, which is metabolically active fatty tissue that dissipates calories in the form of heat. 4. In 2021, a rodent study revealed that intermittent fasting can improve metabolic function by increasing brown adipose tissue, even in obese subjects. 5. Fasting research has also highlighted cognitive benefits, including improved memory and reduced risk of neurodegenerative diseases. 6. Research has also shown improved neural network stability, which may explain why we feel more alert when we fast. 7. In terms of longevity, a 2019 study showed that mice who ate just one meal a day lived significantly longer, regardless of the type of food they ate. 8. Another human study showed that fasting, particularly Early Time-Restricted Feeding (ETRF) fasting, significantly reduced glucose levels and increased the expression of genes linked to longevity and autophagy. 9. In conclusion, research suggests that fasting has health benefits, including improved metabolic response, cognitive benefits, and longevity. It is therefore recommended to try different forms of fasting, including intermittent fasting and ETRF-type fasting.

One of the things I've noticed about intermittent fasting is my sleep is improving. I'm sleeping longer and better. This may also be due to my going low carb, it seems when I'm doing a 16:8 fast with low carbs, I sleep through the night with fewer disruptions and feel more rested when I wake. When I go into carb overload or drink alcohol I have unpleasant dreams, not quite nightmares, but not comforting, and more sleep disruption.

Not doing keto but I have significantly reduced my carb and sugar intake. I've lost 20 lbs since February (started the workout routine way before I started doing fasting. The weight really started coming off faster once I implemented that). My mind/focus/concentration is better as well is my sleep. I wish the MSM would get the word out about this. WAY more people (especially in the USA) need to be doing this. Oh and I jumped right into this 16:8 fasting/time restricted feeding. If I can do it anyone can.

I have tried all types of “fasting”....I put quotes around it because I know many of what I am about to say isn’t really “fasting”...it’s a mono diet. A. 72 hour water fast: hour 12 - 36 can be tough. Last 36 pleasant. Insomnia is a side effect . Sleep is deeper. As you get older hydration becomes more challenging. Have to force myself. B. 36-72 hour beef bone broth fast: or a liquid fast. You can usually work during this as the fats give you energy. Great poops after. I mean like poops I had as a kid kind of poops. C. 47 day grape fast: that was my longest. Done every other kind of time. I’m not sure what it about a grape fast but so long as you can constantly graze, you aren’t hungry. (Fructose?) (Resversatol?) I was actually swimming a mile 5 days a week. Ate maybe 2-3 bags of grapes a day. Energy was through the roof, dare I say almost euphoric. Insomnia just like water fasts. Hydration became a problem..no sodium to retain water I guess. , libido dropped to zero (no fats for hormones?). D. Potato fast: I lasted 12 hours on this one. Felt miserable, lol. Sorry Penn the magician. E. Intermittent fast: probably the most challenging working healthcare and our crazy ass schedules. I feel 12-8 feels more inviting but honestly 8-4 is better. I mostly work swing shift with an occasional overnight and call. I’m jealous of people with normal schedules. I have never ritualized any of the above because of my schedule.

What about what Attia said about losing muscle?

[@search4answers849]

Attia did not have enough fat on his body to do long extended fasting especially as often as he did them.

[@docholliday7381]

I use OMAD, and alternate the time in which I eat. IE sometimes there is 30 hours between my meals and sometimes 18 hours. Its the best I've ever done for my body. and also using keto.

[@mwj5368]

If I'm already in ketosis for 1 1/2 yrs and I do a 3 day fast I found I didn't have to do any easing into my meals. I just started eating again as normal and didn't have any issues of too much too fast after fasting. Why is that? Is it because I was already accustomed to ketosis and also utilizing protein as a source of energy with my Carnivore Diet rather than my former vegetarian diet (was a vegetarian for 32 years with a lot of issues) that had too many carbs? Thanks for another great video I subscribed long ago and many likes too.

I’ve been fasting for 18 months average 14-16 hours. I can feel the change in seasons. Im eating afternoon, window smaller, prior to it getting dark. I think I’m fluctuating because the time change is coming up.

When I look at my life when I was in my twenties I never ate more than one meal a day I was lucky to even eat a bowl of rice even into my thirties I only ate a large dinner now in my fifty’s I start out slow with fruit at 3pm and still eat the bulk of my food late at night when I can finally relax and enjoy a large meal I’ve always been slender and more productive than those around me

[@goodyeoman4534]

Hi, is that because you grew up in poverty or is it cultural reasons? I grew up dirt poor, and would go long periods without eating a decent meal. But that made me go a bit crazy once I got a good job as I now enjoy my food so much lol. Still slim though, and have never put on weight.

I believe that fasting is very beneficial for you and I do agree with the better sleep and I don’t need as much caffeine as before to wake up in the morning. However I have not lost any weight and I don’t believe that it speeds up your metabolism. And I’ve been fasting for a month. And I for caffeine in the morning I drink matcha, by far the strongest green tea.

Can you make a video on hypoglycaemia while fasting? I want to do prolonged fasts but I get hypoglycaemic. Plus I’m on Berberine and inositol for insulin resistance. I have well controlled type 2 diabetes. My A1C went from 9.3 to 6.3 naturally with diet and exercise and inositol. Now I’ve added Berberine. I can get hypoglycaemic at times even when I wasn’t on anything. How can I fast longer with this. I find it even harder at night when I should stop eating much earlier. I get low at night if I don’t eat all evening and find mornings easier for fasting. Please help.

So you watch the videos, presumably to learn/for information . . . But you're entitled to it for free, right? Why begrudge a guy for financial support? He doesn't tell you that you have to or should buy the overpriced tea. Why not just do all this research yourself? You do realize, too, that many of the studies he shares/explains aren't always free, right? Depending on the source, they can be behind paywalls and/or require subscriptions to access. Does this guy ever make direct pleas for your time, money, and/or attention? Is today your first day at KZbin?

What will be your advices for those who suffer a lot during fasting? How to be more adapted to fast? I do keto for 3 month, but it does not help to fast easier... Maybe I need to increase friquency, like fasting every other day? But you said in previous videos that it is too much.. Maybe for a person like me who is very bad at fasting it is ok to increase fasting frequency to be more adapted to it? It seems I still fight with high insulit resistent, even keto does not help...

[@WideAwakeHuman]

Just eat nothing but beef and eggs for a month and then try fasting until lunch a few days a week and before long it’ll get easier. I’ve tried fasting probably half a dozen times over the last 10yrs but just couldn’t make it more than about 6 hrs without getting a headache and feeling horrible until I did the above and I can just stop eating whenever I want and going 24hrs is no big deal. Give it a shot.

[@natasha09179]

Look up Mindy Pelz, MD. She specializes in adapting fasting for the female body/hormone pattern. She says it’s bad for female hormones to fast during certain weeks of your cycle. Best time is during your period.

[@Natashyenka436]

@@natasha09179 thank you! Yes, this is probably my case

[@ma5953]

You need to do it very gradiently. Start eating only 2 meals a day. When you are comfortable with that do one meal a day a couple of times a week. When you are able to do that do a 24 hours fast. And so on. Within a year I went from increasing my fasting window from 20 hours to 44. I did it very slowly as I was having a hard time. Now I can fast without headaches dizziness or nausea. I still get hungry but it s bearable and it goes away. Last but not least take a bit of salt with water while fasting. You need it to keep your electrolytes balanced.

Good stuff

[@donkorte80]

Saw an interview the the Sauk panda guy who is closely related with circadian genes and he was not in favor of moving your fasting times around. These gene like a sun rise and first meal that happens pretty much the same time every day. Moving your meals like getting up late on the weekends screws up the benefits. You are basically giving these genes jet lag. Move meals slowly to follow the sun or not at all.

[@raykeller]

my wife is concerned with our kids following a fasting routine cause they are still under 10 yrs old. I told her that I think its better they start now instead of getting fat or obese first to then add a fasting routing to their diet. can you make a fasting video about kids who are not displaying obesity yet but are children to parents who have/had bad eating habits but are now trying to do better for themselves and want that for their kids? in short, is it dangerous for kids to practice any intermittent or prolonged fasting while young and "developing"? thx brother

[@emsea1658]

That doesnt sound right to restrict calories or fast a growing body before puberty. Im pretty sure that will have detrimental effects, kids have high metabolism they need whole, high quality foods and need to learn to satisfy and respond to real hunger without processed foods and sugar.

[@JustcallmeDebbieB]

Agree. Not for kids.

[@YT1234-i1i]

In every book of fasting they said it's not for kids, pregnant ladies, breastfeeding.

[@barlowwe]

I think teaching kids to not eat after dinner (6:00) until breakfast the next morning (7:00) which would be a 13 hour fast makes a lot of sense and mimics how people used to eat even 10-20 years ago. So, in a way, they’re “fasting” but in a natural way. And teach them to eat a good breakfast, lunch, and dinner with no snacks in between. Those are good “fasting” habits.

[@cherryl225]

speaking of fasting, can you cover ways to prevent [non diabetic] ketoacidosis caused by keto diet / fasting, by covering what causes it? (out of control ketone production / disposal, for example) it might not be common enough to be an issue, but it is for me. to stress the point (not asking advice), i can do 24 hr fasts morning to morning, but if i do 24 hr fasts evening to evening the next day, especially if i continue passed 24 hrs, i have a hard time breathing, cant yawn, and my electrolytes drop off to the point of heart arrhythmia. it takes me days to recover. this never used to happen.

How often do you rotate your fasting?

[@sciencesimplified3890]

You’re very passionate and I’m certain you have good intentions, but i strongly recommend laying out the data in the studies without offering advice.. changing up your fasting time/window is a very potent way to disrupt your circadian rhythm which theoretically could have damaging health effects (i.e. DNA damage and cardiovascular effects).. if you really want to play it safe always stay within the recommended guidelines of the American medical association
