As someone who has been bodybuilding for more than 2 decades I've been used to eating 6+ meals a day as standard. In my early 20's I was capable of maintaining a very lean condition even with a surplus of calories. As I entered my 30's I noticed I was always having to switch between bulks and cuts to stay lean. It became a real juggling act. My metabolism was all over the place with irregular bathroom breaks and I'd often feel bloated through the day. I made lots of dietary changes thinking I may be developing food intolerances. At one point I stumbled upon IF. It's basically the polar opposite to what I'd practiced the majority of my life so I was quite interested to see what would happen if I turned things upside down for a while. It did take several months to wean myself down to OMAD as I'd lived such a long time with always a piece of food in my hand. Once I was down to OMAD though some incredible changes were to follow, not immediately but within around 6 months of practice. I started getting lean, very lean without really trying. I was still eating as many calories as I did through a 6 meal day. I was also able to maintain and gain more muscle in that time despite the fat coming off. Bathroom breaks were brief and like clock work at the same time each morning. I can eat anything without feeling bloated (so much for the suspected food intolerances) and furthermore I feel as energetic as I was in my 20's while having reclaimed my prime physique. I don't know what it is about OMAD but it works wonders for me and I won't be going back to multiple meals a day.
@@paulgomez3318 probably just eats like a 6 course meal lol all calories at once.. I think why this works is because your body isn’t breaking food down all day
@@paulgomez3318 I have to eat 3k calories as well so as much as I want to do OMAD, it actually takes 1-3 hours to have it all so I assume he does the same
I was heavy all my adult life. I’m just about 38. An Ironworker. Always worked my ass off at work but had no concept of diet. 2019 I started fasting and training and eating less carbs. I’m 178. I eat once a day after work at midnight. I feel amazing. Guys at work look at me like I have 3 heads when I tell them I only eat after work every day, and even when I do eat it’s not much. And I’m not hungry. I work non stop with ease, clear head. It’s a cheat code no doubt.
Those of us know the intermittent fasting way know of a life and energy that others have no idea about until they experience it. You then realize how food diets have been marketed to you, your whole life and were conditioned to overeat and we never knew...
Intermittent fasting by itself doesn’t stop you from overeating. It probably reduces your intake if you are totally out of control, but you can smash a lot of calories in an 8 hour window. Conversely if you do both 30mins of cardio and do an hour of weights 5 days a week, you can’t cram the nutrient requirements that causes adequately into a single meal. One of the reasons you age less on one meal is because you also are forced to restrict the stress on your body, because you can’t nourish it properly. Query whether this approach produces competing goals.
I have been doing OMAD for a few months now and I have never felt better in my life! Fasting changes your life in every aspect: physically, mentally, and spiritually! Thank you for sharing that with us! People need to know it!
@@wanderingandroid That is just a limiting belief that you have. I actually help people overcome limiting beliefs, if you might be interested. I'd love to change your mind on this one!
Been trying this. I cook my 1 meal in the middle of the day, a lunch essentially, so I'm a little hungry in the morning and very hungry by lunch time. I make a massive meal and I really enjoy eating it and cooking is less of a chore because I'm looking forward to it so much more. The result after a week is that I eat almost no junk food now. Most of my food is substantial whole foods. My cooking is more creative and my grocery list is more focused and healthy. I find at about an hour leading up to my meal I'm thinking of all the things I really want to eat (and I allow myself to eat all of them) and so I'm stepping up to the stove with ideas instead of just eating out of boredom or habit. I honestly don't crave the snack foods I used to munch on throughout the day. I could just still be in the honeymoon phase but this feels really natural. The feeling of hunger isn't so terrible either. Honestly it reminds me of being a kid where there were a lot more times when I wouldn't be able to eat whenever I wanted to unlike as an adult when I can pretty much eat continually if I desire. Another benefit I didn't anticipate is that I dirty almost no dishes now. I'll have one plate and usually just a single pot/pan to clean up each day. It really harmonizes with the more minimalist lifestyle I aspire to.
Interesting. Makes sense. May I ask if you feel stuffed at all after eating the one large meal, and do you have an idea of the average number of calories, very approximately?
@@andthereisntone3454 I eat like I'm going into hibernation lol and I feel very stuffed afterward. I've never really counted calories, I've always just based my eating habits on how full I feel but I think it's probably around 2000-2500 or a little less. Maybe I won't pig out as much the longer I do this but for now it feels good and I'm enjoying the routine.
Interesting reading, I stopped eating breakfast about a year ago and I’m in the best shape I’ve been in since my early 20s (I’m 36 now) and this is without going the gym. Like you I find by midday/1 I’m really ready to eat but some days if I’m really busy at work I reckon I could last till 4 when I finish. I sleep better and have way more dreams, I still can’t sleep right through without taking a piss but I’m only up once usually and I feel so more focused and energised through the day.
Before someone doubts David's statement, This is his credential "David Andrew Sinclair AO is an Australian biologist who is a professor of genetics and co-director of the Paul F. Glenn Center for Biology of Aging Research at Harvard Medical School". I feel like it will be better if there was a bit of description in the video itself.
@@Horneycorn You know what, no. I’m not looking to be scrawny with no muscle and and looking under nourished. There is nothing wrong with three meals a day portioned and healthy. Sure it can be done but I live in reality and know that I may be able to do it but why?
@@seandunn2062 You're right in the fact that there is nothing wrong with 3 healthy portioned meals. Nutrition and health is one of those areas that the more you learn the more you realize you don't know. You could for example could eat the same 2500 calories in the morning by having a huge healthy breakfast to fuel up for the day or you could eat a very large lunch and do OMAD that way you don't need to only eat your one meal at the end of the day. A lot of the benefits of fasting have to do with "cell clean up" & maintaining consistent blood sugar/insulin levels. Specifically with longer periods of fasting (i.e. 3 days) the body begins to breakdown damaged cells to prioritize healthy ones. The other thing to keep in mind is they are talking about longevity which is different than performance. Think about the what a strong man looks like. That is not the healthiest body for longevity but the trade some longevity for massive performance gains. It works the other way as well. If you're interested in learning more there are tons of great podcast that dive into the science of various things like fasting, keto, paleo, etc. Also deciding experimenting what works best for you goes a long way, but it's hard to try different things if you don't understand why you might do them and the potential benefits and tradeoffs.
Sinclair has worked out the optimal formula. It does make you, as Fridman says, more contemplative, aware of what makes you sparkle (food, people, places, everything) and what dims your light. Thank you. Vicki-Louise
OMAD is not difficult or extreme once you adapt. I find that my energy levels are higher, my workouts are more enjoyable (probably because I'm not digesting while training) and I'm never hungry during the day which makes staying lean quite feasible. Also just not having to worry about food is such a blessing for me, I've always been a glutton who had food on his mind all day and now I can direct all my energy and focus to the task at hand. All that said, I recognize diet is a very personal topic. I recommend experimenting with lots of diets and not worrying too much about slipping up from time to time. As far as diet content goes I would focus on getting enough omega 3's, vitamin C, eating enough meat (zink, B vitamins etc.) and limiting sugar. Also supplementing vitamin D3 was a gamechanger.
I do physical therapy in a nursing home setting on patients recovering from surgery, illness, etc. Work with a lot of 90+ year old folk. Despite being in a nursing home for a short stay many of them are in relative good health for their age. I ask them all for the secrets to their long life. None of them did anything in particular. I notice that almost all of them have a pleasant disposition and sense of humor. Being from the Midwest and growing up in the first half of the 20th century most of them were farmers for at least part of their lives. None of them say they lived off one meal a day. Many of them ate the standard midwestern "meat and potatoes" diet. It seems to be genetics. They often look better than many patients I see in their 70s that had nearly identical lifestyles but have had many more health issues. Regardless, none of them seem very excited about being almost 100 years old because by that point in their lives they're often the only one left in their immediate family (siblings, cousins, even many times their own children). Most of them have this attitude that they've lived a full life and are concerned about dying as you are when you're younger. I don't doubt the science is good for eating a particular way may result in your cells performing better over the long run, but in the end you're only going to live so long anyways. Don't over complicate it. Try to overall eat a healthy and balanced diet, sleep well, enjoy yourself and others. Nothing wrong with fasting and playing around with your diet to see what feels best. I wouldn't eat in a way that makes me feel hungry, tired, etc. just to *maybe* extend my life.
one meal a day will not make you feel hungry or tired once you adapt. I love it more than any diet I've ever tried. Outside of that I agree with everything you said, life extension is fun and all but it shouldn't stand in the way of your happiness.
Well said, everyone is trying to be a revolutionary and promote some fad or "getting back to our roots" romanticized nonsense. I wouldn't advocate eating one meal a day if you're in a very active mentally demanding job, you can certainly try it occasionally as long as your otherwise fit and healthy.
I eat one meal per day with only black coffee and water in between. I feel much sharper and more energetic than I did in years past when I ate 2-3 meals per day. The only difficult part is hitting your macro nutrient goals in that one meal, but it can be done with proper planning.
I used to think the same thing, watch literally any video about aspartame, it isn't bad for you and you eat it everyday anyway because it is found in nature. The worse thing for you in diet soda is the food coloring probably. Some people are so brainwashed they think it is better to drink two cups of sugar everyday than 3 molecules of aspartame lol
I've been doing OMAD for several months. I have lost a stone and agree that energy wise, I am fine, even during hectic work days teaching. I think you need to choose the one meal carefully, I have a protein shake before the meal to ensure I keep my levels of serotonin etc good. As many may not get alot of protein on OMAD, which is essential for your body to make those feel good chemicals.
@@Fx_- That's your body getting rid of toxins and flushing out. I used to get that too. I've done numerous extended fasts. If you have any questions, you can ask me. Exercise also increases autophagy in my experience. The more energy you put out, the stronger the regeneration is.
@@DribblyDik I would, I've done a a few in the past and I start to feel really good mentally a few days into the water fast. For more serious/life threatening issues a dry fast is better, 3-4 days does wonders. But it is very uncomfortable. The best way to fast is to combine them... Water fast for a day or 2 to flush out your body and then move into the dry fast. Going for walks and having fresh air is also important during the fast, some exercise also. Be strong and I wish you the best of luck :)
Well at least you are having fun and people are admiring lol! In all seriousness, yes, the anabolics/GH/insulin/IGF is going to speed up aging, but if you build enough muscle, you can maintain that on very little stuff in the future.
i would say show me a person who eats 1 meal a day and lived longer than all other people. have not found any so far. most long-lived population ate more than 1 time a day.
I sincerely from age 5 didn't want breakfast because i had no appetite. My mom had heard that breakfast is the most important meal of the day, and therefore she made me oatmeal. i ate it and emidiatly at 10'clock sharp i felt a ravenous hunger that only could be fullfilled with anything else than healthy food, but white bread in various forms and lots of it. In my teens i could then skip the breakfast, but she wasnt happy about it, and i just felt better and more genuine hungry at 12'clock. But after lunch i was always not active and my mind kinda shut down i feel. So thats when i started experiment with not eating lunch, only because nothing was "too much" or "i cant do it" or "this is too hard" only lets go. This developed into me only eating one meal a day, but actually worry about it. Thinking i was malnutritioned. I start read on the internet and boom OMAD is there and it is freakin healthy. That just blew me away, that my body saying this is natural for you to eat this way. Was always criticised and still is today.
I started intermittent wasting and feel completely liberated. I am shedding body hair, my teeth have begun to loosen and fall out, which is a huge relief. Yet, I am finding that I want to sleep a lot more - which is great since I work night shift. I just hate the hallucinations. Lately I have been having apocalyptic Christian visions of the most dreadful sort. Black wings, growling and horrid screaming, eternal pain and degradation. I feel like I am possessed by a hell demon.is this due to low vitamin k?
I did a 3 day fast for spiritual reasons. No food. No water. It was amazing! I got the answers and blessings I was looking and praying for. I also lost 10lbs and water never tasted so good.
I've been eating one meal a day since I was around 12. I'm 37 now and I do look like I am in my early to mid-twenties. I'd reckon that it was due to genetics, and not my diet... Mind you, I rarely consume fast food, and have one home-cooked meal a day.
@@Mr-E. Probably a combination of behaviors and not wanting to eat a lunch that my mom sometimes packed. Growing up in my teens, I also never wanted to wake up until I absolutely had to, so I very rarely had breakfast. I also don't enjoy meal preparation, or cooking whatsoever. But, when I do have supper, I generally have a fairly large meal and will spend upwards of an hour just to finish it.
@@Kyntheria Gotcha, that makes sense. I was never big on breakfast for the same reason (wanting sleep instead). I also eat one bigger meal in the evenings and a little snack after that, but I intentionally started doing that about 5 years ago after I learned about the benefits. It feels a bit like a "life hack", especially when coworkers are whining about lunch and saying they are hungry lol.
You were lucky. We lived for three months in a paper bag in a septic tank. We used to have to get up at six in the morning, clean the paper bag, eat a crust of stale bread, go to work down t' mill, fourteen hours a day, week-in week-out, for sixpence a week, and when we got home our Dad would thrash us to sleep wi' his belt
My dad has been doing this for 40 years. He's 74 and looks maybe 50 if not younger, and has started to exercise only 3 months ago. Is in no way fat. And I've been doing this for 13 years, I'm 38 right now and was 37 when I took my photo for my RUclips profile picture
We're living in a better era now. There is a broadening understanding of the benefits of different approaches. I eat one meal a day now and don't feel hungry in between. Low carb. But if hiking or otherwise getting shit done ill pound down 3 or more meals and feel the energy in me like an excited puppy. Its awesome experiencing this stuff and seeing the benefits.
I have been doing OMAD and/or IF for last 3 years but after meal I get super suuuper sleepy... Is this the para-sympathetic system at work and how can I prevent sleepiness after an IF or OMAD meal?? cheers thanks AND MIGHT I SAY THAT THIS IS THE BEST LIFE HACK THERE IS!! U can do it.. It's very easy after the first 2-3 days ":^)
@@_SPREZZATURA_McGEE_ Switch your OMAD from evening to morning. In the morning your body is primed to store as much glucose in your muscles as possible (I assume in anticipation of a day of hard work) and as a consequence, you get the lowest insulin spike. The evening is the complete opposite and you may end up going a little hypoglycemic if the meal is big.
@@hynjus001THANK YOU for ur suggestion. I can go without food all day knowing I'm gonna eat at 7pm. It's gonna be tough knowing that after my brkfast/brunch OMAD that I am DONE for the day, till tomorrow, were I to eat early. I know how my Monkey Brain works. I tried this early meal routine(years ago) and often ended up eating at 10 or 11pm :/ LOL got any tips or tricks? Be Well, Buddy -cheers
@@_SPREZZATURA_McGEE_ Same, no matter how much I ate in the am, I was so hungry come the evening.. now i I don't eat in the am, I have more energy and get truly hungry around 4pm :)
I'm 78 and in pretty good health. I've been doing OMAD for a couple of years but am starting to hear that this practice may not be advisable for a person of my age. I'd appreciate references to other RUclips videos or articles I might read to help with my good health and longevity.
I've lived by this method for a while somewhat .. Mostly with intermittent fasting.. When I do eat.. I eat.. Most of the time I wake up in the night after a sleep have a few hours up with food and then back to bed for a few hours .. Feel great the next day
I've been fighting my natural inclination to eat one meal a day since I was a kid because of the pushback from family, friends, and the accepted societal wisdom. Not sure it's for everyone but I generally gravitate to that if I don't consciously try not to. Have no idea if I'm healthier..but I'm going to stop feeling bad about it!
In 2019 I decided to stop drinking for a month. That led to an overall change in my life throughout that month. To the point I just never picked up drinking again. To this day. Intermittent fasting and long fasts entered my life. I dropped over 30 pounds in months. I started drinking a lot of water again instead of other liquids. I now only drink water and coffee. That’s it. Since Jan 2020 I’ve been living an OMAD life with casual 24 and 48 hour fasts here and there. I’ll do a longer one if I feel good during a fast. Never done more than 96 hours. Body and mind have not been able to endure it, I am 44 and people are surprised I am not in my mid 30’s. I don’t try to explain much to people who are bewildered by my routine. I have encountered that they don’t get it or don’t want to get it. They say I look amazing and when I tell them how they act as if I’m speaking Mandarin and it’s dangerous and unhealthy. How if I look healthier than most people my age?
i have tried OMAD for about a month before and i like it. i'm a vegan and I also do a lot of exercise like bodyweight training and Jiu-jitsu and also some jogging too. and I found for me it is difficult to maintain my weight I guess that's because I did too much exercise and consumed too much energy. then I change my diet to 2MAD. and now i'm starting to change my diet to OMAD in order to quit drinking. I also recalled that was the first time I quitting drinking for 45 days during my earlier OMAD diet period. so I hope this time it will work again to help me became sober once for all.
Since i eat once a day i have su much more energy over the course of the day it is not even compareable. I only eat in the evening and i don't get the tiredness in the mid day. Just 100% concentration. I don think though everyone can or should do it. The types that cant get fat easily and are thin shouldnt or cant do it in my opinion.
Did OMAD for an entire year. At the beginning it seems to bring benefits, though I put this down to eliminating unhealthy foods or certain foods at the wrong time of day. After a few months I noticed my energy levels were declining as I was increasing physical activity. My meals were usually steak or fish accompanied with Bok Choy and Green onions. I reach the same conclusion when I ditched plant based diets after 2 years, there is no one diet fits all. Also measuring Telomeres on mice doesn't provide a definitive parallel to that of humans. Looks like Sinclair also used hair dye to reverse his age.
You sound nutrient deficient based off lack of diversity and you were probably always in a low carb but not quite keto diet, of course you felt low energy
@@bobbobson4030 my body actually started to store more fat around my stomach. Three meals a day works better for me, I build muscle more efficiently now and burn fat easier.
My concern with OMAD is getting in enough protein to reduce sarcopenia and put on muscle-something that’s already a challenge as an older female. I certainly can’t digest the amount of protein I’d need in a day in one sitting.
I will never skip breakfast. It’s always my favourite meal of the day with a coffee. If I don’t have it i just obsess about food and can’t concentrate at work. Happily skip dinner as I hate trying to sleep with a full stomach. Lunch is pretty easy to skip too when busy during the day.
When I lived alone I used to skip means constantly because I was in front of PC all the time, mostly just eating snacks, so probably 1 meal every other day, I'm 29 and I still look like I'm 20.
I drink Bulletproof coffee with turmeric in the morning. I snack on piscasio nuts, raw cocoa and green leaf salads during the day. In the evening I have a very large meal including eggs and meat. Am Iikely to get enough autophagy?
If you have a physical job, fasting throughout the day will be absolutely brutal. It's doable, but I personally don't recommend not eating the whole day if you're a builder or gardener for example. Very small 100 calorie snacks to have something to burn on is what works for me on work days. But any other days I fast until 4pm.
One question, if you’re fasting but you’re a cyclist what would be a good suggestion? Not eating in the morning and riding 30+ miles is not an option. However, eating a ridiculously large breakfast and trying to ride is counter productive and still burns energy. I guess my question would be: Is there anyone here who does endurance sports and fast? It seems to me that someone who is an endurance athlete and eats less would cause more harm then good. I could be wrong, I frankly don’t give a damn about aging I eat mostly whole fruits and vegetables and eat meat about two or three times a week (no pork). My energy levels are great and I really don’t feel hindered by my current diet, I would just like another opinion.
OMAD is nothing short of incredible in my experience. Restored my metabolism to that of my early 20's (38 now) For reference in my early 20's I could eat junk all day and still had visible abs and lean physique. In my 30's I had to tighten the screws on diet and exercise considerably else I'd morph into Dad bod seemingly overnight. OMAD completely reversed this and the most amazing thing is the simplicity of it. I'm not one for being strictly adherent to rules of die hard OMAD'ers. I'll allow a 2 hour window as opposed to 60 minutes advised. That way I never feel pressured to race through a meal. With 60 minutes I'd always felt like I had to beat the clock especially on days I had a lower appetite and I've generally been the last to finish my food at the table. My one meal is breakfast but occasionally I get side tracked and I'll skip breakfast catching up with lunch so going 30 hours fasted but I always make it a habit to keep the minimum fasted time of 22-23 hours between feedings. As a bodybuilder used to 6+ meals a day I was somewhat skeptical I could make gains on such a protocol and I did find in the short term my strength levels suffered. After 4-6 weeks however my body really adapted and my workouts were even more productive than ever. Great energy, pumps and strength/muscle gains on par with my 6 meal a day protocol but without storing excess body fat. I think a lot of bodybuilders who try OMAD and complain about loss of strength perhaps haven't given it a fair shot. A fair go would be at least a 3 month trial and of course ensuring you get your calories in even if that means a 2 hour feeding window.
Hey man. I would like to ask, how many calories per day do you eat in that 2 hour window? :) not sure how getting in around 3k calories is possible when you workout every day and are geneticaly rather skinny
@@medicvlogs4110 My intake is typically between 2-3k. I don't think it's that difficult to consume 3k calories but everyone is different. You could try including high calorie shakes or extend the feeding time to a 3-4 hour window with an hour break between meals. I doubt there's going to be much difference in terms of the benefits seen from a 20 hour vs 23 hour fast. You want to find a schedule that works best for you so you're more likely to stick to it.
@@dune7824 That’s great. I read many people get slower digestion and bm’s less frequently with OMAD. Why is the window for eating so important? I’m not trying to lose weight but to maintain or gain weight. A big meal takes me 3 hours to eat. I’m doing two meals a day because of slow digestion which causes me bloating and feeling full all the time. Am thinking of OMAD to give my digestion time to help process all that food even more.
The stomach needs to rest in order to slow down aging!! Once a day is not easy for most people. twice a day is possible for most and it is better to start doing 2 a day first~~
He says to put our bodies in a defense state like whales do and mice don't. I would think that mice are constantly in a defense state being a prey for so many hunters.
I knew it!!! So it wasn't just me. Over time I always look younger when I ate 1 meal a day. My face looks younger with fewer lines but when I eat normally I look older.
what's more important for longevity, calorie restriction, or time in a fast? Being an athlete, I am much more open to simply condensing my calorie intake into a smaller window than reducing my calorie total intake. It seems both methods work but I haven't heard anything that compares them.
despite what many gurus sell us, we simply do not have that information for long term. we do know calorie restriction works and that's it. it's the only robust long term data we have for health span. fasting does calorie restriction automatically so it might just be that for long term health. but anecdotally people feel amazing on it probably because their bodies aren't being taxed processing food all the time.
Long term moderate caloric restriction with nutrient excellence is shown to be best for longevity. Fasting can be used as a good tool to moderately restrict your caloric intake. The key is then eating nutrient dense food. Athletes are gonna require more calories by nature they are burning more. Fasting can still be a great tool if you want to lean up and in some workouts it actually helps. But in competition phase or really intense workouts up the calories try to eat before too especially some good carbohydrates.
I started cutting(trying) down couple days ago... Yep,time really slows down. I usually fill up on water tho. I noticed that after waking up and having plans for the day,once I have breakfast I feel heavy all the conviction of the early hours almost completely disappears;anyhoo I'm trying to get to 1 meal a day from 3 sometimes 4 with snacks in between. I'm down to 2 meals with no snacks and just alotta water. Well,what do I know?!?
Who are the sources saying that drinking (black cofee and tea) takes you out of fasting state? All the sources I've read seem to suggest that this isn't the case.
This is true only for non acti e athletic people. If you are training heavily in some area you need to eat at least 2 meals. I'm sure there are exceptions but for optimal output for say a spartan race training, you need 2 meals a day no question about it. These diet are typically to be implemented for historically sedentary people or past heavy physical activity age.
Lies , lies and More lies. My energy levels are insane when I fast . I’m never tired , I wake up with the most energy and it lasts until I eat my first meal . I been pumping in the gym , running and getting my cardio in before I eat and I feel fucking great .
Are there ANY human studies that show OMAD or any other type of meal timing/restriction has any affect on longevity? Cause i cant find a single one. But i can find plenty of studies showing plain old calorie restriction works just as well
This is what I was wondering too. I watched a video on intermittent fasting from Dr. Eric Berg and he mentioned that what matters is how often you eat and not necessarily how much you eat. So I'm assuming this means you would just have to eat a lot of calories in your one meal, or maybe try a short window of a few hours to get your daily calories? Hopefully someone knowledgeable in this can answer this.
May I ask what you usually eat, and what size portions? And do you literally only consume anything with calories once per day, or do you also eat fruit, drink shakes, have coffee with milk, or anything else with calories? I'm asking because I'm very interested in trying this. - Cheers.
@@andthereisntone3454 LOL... Im almost embarrassed to answer. I sip a large coffee that lasts all day to go along with my 20 cigs and 3 joints, maybe a donut or apple but rarely. Then after work I eat maybe 10 or 20,000 calories of pizza, burgers, massive salads, lasagnas......about a three or 4 lb meal. Im no health nut, three meals a day just never made any sense to me ....evolutionarily;). NOTE: I usually do very physical work/play. and burn alot of calories.
I would now ask that you all take the opportunity to think long and hard about this sentence, I'm now over 40 years old and i would have loved to experience loyalty and commitment from a women. Even though this is the case I would still NEVER be interested in manufacturing such things... if it does not happen its not meant to happen.
I intermittent fast cause I’m poor and I gotta say with how much weed I smoke I don’t notice an energy difference. But when I do eat, that food coma hits
Does anyone know how you’re able to maintain muscle mass and only eat once per day? Do you literally eat all of your calories in one sitting in one huge meal? I guess that’s literally the only way but doesn’t seem very practical.
I wonder there are so many vids for this, but what about the vitamins and minerals how to even get that in one meal? Also you know that today's food are so un-natrual mostly they are mixed with chemicals to grow things fast, so again what about the daily vitamins and minerals intake? Wont this be bad in long term? Then there's supplement, are those even good enough?
Im trying this now and it feels right. It feels real. The energy that is created is different. My question is, can i do est like shit on the weekend and one meal a day during the week and get lots of benefits still? 😅😂
It would be interesting to see the scientific data behind intermittent fasting. I just started about couple weeks ago and my goal is to see the results in 2 to 3 months. If it works go 6 months.
Great, advice for humans based on data from yeast, mice and whales. I also suggest jumping off a cliff and bouncing your arms around to fly, and I've got data from birds to back me up here.
@J B there is a difference between doing research 101 and going on a podcast giving advice as if it worked for humans or were settled science. I guess the one not familiar is you.
I often find David Sinclair annoying but he's spot on about habit. Eating frequently and snacking are merely habits, in this case deadly habits, but habits can be changed. I eat intuitively these days, without rigid rules or expectations, so some days I eat more or less, but I do notice that a slightly empty stomach feels way better than a stuffed one. The body has its own wisdom, for sure.
Skipping breakfast is bad idea because it misses the prime time for digestion: a) stomach meridian is most active between 7 to 9 am and b) spleen meridian active between 9 to 11am. Better to skip dinner as the small intestine meridian, which is last in the digestion process, is active between 1 to 3pm. Cheers.
@Ross Karr - You’re confusing OMAD with skipping the Caloric content of the other 2 Meals. Those on OMAD consume 3 Meals worth of Calories in a single shorter time window, often 6 Hours or less. They have also adapted to primarily burning Fat (Ketones) for energy, rather than Glucose. The advantage is your Body’s Glycogen Store is relatively small, only about 2500 Calories, while the Fat Store can be 200,000 Calories or more. If you are Carbohydrate-Adapted, you must constantly refill your Glycogen Store during the Day or run out of easily available energy. If you’ve become more adapted to burning Fat by drastically limiting the Carbohydrates you consume, you’re using a larger “fuel tank” and don’t need to refill it as often to maintain your energy level.
@@andrewstrakele6815 2.5k or less calories is fine depending on what you do. By all means use fats instead of carbs for your energy source if you want to exceed that. There still neurological reasons to consume liquid carbs throughout the day, so fixate it at your peril.
@@qx-jd9mh - Actually, Carbohydrate consumption is completely unnecessary. The Liver can manufacture all the Glucose your Body needs from Protein or Ketone substrates. There are no essential Carbohydrates. In addition, the Brain loves using Ketones for energy to spare Glucose usage. It is the reason Ketogenic Diets are useful in the treatment of a whole host of Neurological conditions.

As someone who has been bodybuilding for more than 2 decades I've been used to eating 6+ meals a day as standard. In my early 20's I was capable of maintaining a very lean condition even with a surplus of calories. As I entered my 30's I noticed I was always having to switch between bulks and cuts to stay lean. It became a real juggling act. My metabolism was all over the place with irregular bathroom breaks and I'd often feel bloated through the day. I made lots of dietary changes thinking I may be developing food intolerances.
At one point I stumbled upon IF. It's basically the polar opposite to what I'd practiced the majority of my life so I was quite interested to see what would happen if I turned things upside down for a while. It did take several months to wean myself down to OMAD as I'd lived such a long time with always a piece of food in my hand. Once I was down to OMAD though some incredible changes were to follow, not immediately but within around 6 months of practice.
I started getting lean, very lean without really trying. I was still eating as many calories as I did through a 6 meal day. I was also able to maintain and gain more muscle in that time despite the fat coming off. Bathroom breaks were brief and like clock work at the same time each morning. I can eat anything without feeling bloated (so much for the suspected food intolerances) and furthermore I feel as energetic as I was in my 20's while having reclaimed my prime physique. I don't know what it is about OMAD but it works wonders for me and I won't be going back to multiple meals a day.
Bro thank you so much for this comment, do you take whey protein or any other supplement ?

Is OMAD the same thing as doing 24 hour fast?
@@jamest4198 yes. It's one meal a day, ergo you eat every 24 hs aprox
@@JanoDo Thankyou for clarifying.
Can't you get ulcers from eating very little?
Intermittent fasting by itself doesn’t stop you from overeating. It probably reduces your intake if you are totally out of control, but you can smash a lot of calories in an 8 hour window.
Conversely if you do both 30mins of cardio and do an hour of weights 5 days a week, you can’t cram the nutrient requirements that causes adequately into a single meal.
One of the reasons you age less on one meal is because you also are forced to restrict the stress on your body, because you can’t nourish it properly.
Query whether this approach produces competing goals.
I have been doing OMAD for a few months now and I have never felt better in my life! Fasting changes your life in every aspect: physically, mentally, and spiritually! Thank you for sharing that with us! People need to know it!

Been trying this. I cook my 1 meal in the middle of the day, a lunch essentially, so I'm a little hungry in the morning and very hungry by lunch time. I make a massive meal and I really enjoy eating it and cooking is less of a chore because I'm looking forward to it so much more. The result after a week is that I eat almost no junk food now. Most of my food is substantial whole foods. My cooking is more creative and my grocery list is more focused and healthy. I find at about an hour leading up to my meal I'm thinking of all the things I really want to eat (and I allow myself to eat all of them) and so I'm stepping up to the stove with ideas instead of just eating out of boredom or habit. I honestly don't crave the snack foods I used to munch on throughout the day. I could just still be in the honeymoon phase but this feels really natural. The feeling of hunger isn't so terrible either. Honestly it reminds me of being a kid where there were a lot more times when I wouldn't be able to eat whenever I wanted to unlike as an adult when I can pretty much eat continually if I desire. Another benefit I didn't anticipate is that I dirty almost no dishes now. I'll have one plate and usually just a single pot/pan to clean up each day. It really harmonizes with the more minimalist lifestyle I aspire to.
Interesting. Makes sense. May I ask if you feel stuffed at all after eating the one large meal, and do you have an idea of the average number of calories, very approximately?
@@andthereisntone3454 I eat like I'm going into hibernation lol and I feel very stuffed afterward. I've never really counted calories, I've always just based my eating habits on how full I feel but I think it's probably around 2000-2500 or a little less. Maybe I won't pig out as much the longer I do this but for now it feels good and I'm enjoying the routine.
@@rasputozen Cheers.
Interesting reading, I stopped eating breakfast about a year ago and I’m in the best shape I’ve been in since my early 20s (I’m 36 now) and this is without going the gym. Like you I find by midday/1 I’m really ready to eat but some days if I’m really busy at work I reckon I could last till 4 when I finish. I sleep better and have way more dreams, I still can’t sleep right through without taking a piss but I’m only up once usually and I feel so more focused and energised through the day.
I'm starting today, hope it works.

@@seandunn2062 You're right in the fact that there is nothing wrong with 3 healthy portioned meals. Nutrition and health is one of those areas that the more you learn the more you realize you don't know.
You could for example could eat the same 2500 calories in the morning by having a huge healthy breakfast to fuel up for the day or you could eat a very large lunch and do OMAD that way you don't need to only eat your one meal at the end of the day.
A lot of the benefits of fasting have to do with "cell clean up" & maintaining consistent blood sugar/insulin levels. Specifically with longer periods of fasting (i.e. 3 days) the body begins to breakdown damaged cells to prioritize healthy ones.
The other thing to keep in mind is they are talking about longevity which is different than performance. Think about the what a strong man looks like. That is not the healthiest body for longevity but the trade some longevity for massive performance gains. It works the other way as well.
If you're interested in learning more there are tons of great podcast that dive into the science of various things like fasting, keto, paleo, etc. Also deciding experimenting what works best for you goes a long way, but it's hard to try different things if you don't understand why you might do them and the potential benefits and tradeoffs.
Sinclair has worked out the optimal formula. It does make you, as Fridman says, more contemplative, aware of what makes you sparkle (food, people, places, everything) and what dims your light. Thank you. Vicki-Louise
OMAD is not difficult or extreme once you adapt. I find that my energy levels are higher, my workouts are more enjoyable (probably because I'm not digesting while training) and I'm never hungry during the day which makes staying lean quite feasible. Also just not having to worry about food is such a blessing for me, I've always been a glutton who had food on his mind all day and now I can direct all my energy and focus to the task at hand. All that said, I recognize diet is a very personal topic. I recommend experimenting with lots of diets and not worrying too much about slipping up from time to time. As far as diet content goes I would focus on getting enough omega 3's, vitamin C, eating enough meat (zink, B vitamins etc.) and limiting sugar. Also supplementing vitamin D3 was a gamechanger.
I do physical therapy in a nursing home setting on patients recovering from surgery, illness, etc. Work with a lot of 90+ year old folk. Despite being in a nursing home for a short stay many of them are in relative good health for their age. I ask them all for the secrets to their long life. None of them did anything in particular. I notice that almost all of them have a pleasant disposition and sense of humor. Being from the Midwest and growing up in the first half of the 20th century most of them were farmers for at least part of their lives. None of them say they lived off one meal a day. Many of them ate the standard midwestern "meat and potatoes" diet. It seems to be genetics. They often look better than many patients I see in their 70s that had nearly identical lifestyles but have had many more health issues. Regardless, none of them seem very excited about being almost 100 years old because by that point in their lives they're often the only one left in their immediate family (siblings, cousins, even many times their own children). Most of them have this attitude that they've lived a full life and are concerned about dying as you are when you're younger.
I don't doubt the science is good for eating a particular way may result in your cells performing better over the long run, but in the end you're only going to live so long anyways. Don't over complicate it. Try to overall eat a healthy and balanced diet, sleep well, enjoy yourself and others. Nothing wrong with fasting and playing around with your diet to see what feels best. I wouldn't eat in a way that makes me feel hungry, tired, etc. just to *maybe* extend my life.
one meal a day will not make you feel hungry or tired once you adapt. I love it more than any diet I've ever tried. Outside of that I agree with everything you said, life extension is fun and all but it shouldn't stand in the way of your happiness.
Well said, everyone is trying to be a revolutionary and promote some fad or "getting back to our roots" romanticized nonsense. I wouldn't advocate eating one meal a day if you're in a very active mentally demanding job, you can certainly try it occasionally as long as your otherwise fit and healthy.

I eat one meal per day with only black coffee and water in between. I feel much sharper and more energetic than I did in years past when I ate 2-3 meals per day. The only difficult part is hitting your macro nutrient goals in that one meal, but it can be done with proper planning.

I've been doing OMAD for several months. I have lost a stone and agree that energy wise, I am fine, even during hectic work days teaching.

I sincerely from age 5 didn't want breakfast because i had no appetite. My mom had heard that breakfast is the most important meal of the day, and therefore she made me oatmeal. i ate it and emidiatly at 10'clock sharp i felt a ravenous hunger that only could be fullfilled with anything else than healthy food, but white bread in various forms and lots of it. In my teens i could then skip the breakfast, but she wasnt happy about it, and i just felt better and more genuine hungry at 12'clock. But after lunch i was always not active and my mind kinda shut down i feel. So thats when i started experiment with not eating lunch, only because nothing was "too much" or "i cant do it" or "this is too hard" only lets go. This developed into me only eating one meal a day, but actually worry about it. Thinking i was malnutritioned. I start read on the internet and boom OMAD is there and it is freakin healthy. That just blew me away, that my body saying this is natural for you to eat this way. Was always criticised and still is today.

In 2019 I decided to stop drinking for a month. That led to an overall change in my life throughout that month. To the point I just never picked up drinking again. To this day. Intermittent fasting and long fasts entered my life. I dropped over 30 pounds in months. I started drinking a lot of water again instead of other liquids. I now only drink water and coffee. That’s it. Since Jan 2020 I’ve been living an OMAD life with casual 24 and 48 hour fasts here and there. I’ll do a longer one if I feel good during a fast. Never done more than 96 hours. Body and mind have not been able to endure it, I am 44 and people are surprised I am not in my mid 30’s. I don’t try to explain much to people who are bewildered by my routine. I have encountered that they don’t get it or don’t want to get it. They say I look amazing and when I tell them how they act as if I’m speaking Mandarin and it’s dangerous and unhealthy. How if I look healthier than most people my age?
i have tried OMAD for about a month before and i like it. i'm a vegan and I also do a lot of exercise like bodyweight training and Jiu-jitsu and also some jogging too. and I found for me it is difficult to maintain my weight I guess that's because I did too much exercise and consumed too much energy. then I change my diet to 2MAD. and now i'm starting to change my diet to OMAD in order to quit drinking. I also recalled that was the first time I quitting drinking for 45 days during my earlier OMAD diet period. so I hope this time it will work again to help me became sober once for all.
Since i eat once a day i have su much more energy over the course of the day it is not even compareable. I only eat in the evening and i don't get the tiredness in the mid day. Just 100% concentration. I don think though everyone can or should do it. The types that cant get fat easily and are thin shouldnt or cant do it in my opinion.
Did OMAD for an entire year. At the beginning it seems to bring benefits, though I put this down to eliminating unhealthy foods or certain foods at the wrong time of day. After a few months I noticed my energy levels were declining as I was increasing physical activity.
My meals were usually steak or fish accompanied with Bok Choy and Green onions.

I don't think Thomas Sowell is what he seems
@@damejohnson9511 what
@@damejohnson9511 I know, he’s more of a genius than he seems to be, just too modest to admit it.
One question, if you’re fasting but you’re a cyclist what would be a good suggestion? Not eating in the morning and riding 30+ miles is not an option. However, eating a ridiculously large breakfast and trying to ride is counter productive and still burns energy. I guess my question would be: Is there anyone here who does endurance sports and fast? It seems to me that someone who is an endurance athlete and eats less would cause more harm then good. I could be wrong, I frankly don’t give a damn about aging I eat mostly whole fruits and vegetables and eat meat about two or three times a week (no pork). My energy levels are great and I really don’t feel hindered by my current diet, I would just like another opinion.
OMAD is nothing short of incredible in my experience. Restored my metabolism to that of my early 20's (38 now) For reference in my early 20's I could eat junk all day and still had visible abs and lean physique. In my 30's I had to tighten the screws on diet and exercise considerably else I'd morph into Dad bod seemingly overnight. OMAD completely reversed this and the most amazing thing is the simplicity of it.
I'm not one for being strictly adherent to rules of die hard OMAD'ers. I'll allow a 2 hour window as opposed to 60 minutes advised. That way I never feel pressured to race through a meal. With 60 minutes I'd always felt like I had to beat the clock especially on days I had a lower appetite and I've generally been the last to finish my food at the table. My one meal is breakfast but occasionally I get side tracked and I'll skip breakfast catching up with lunch so going 30 hours fasted but I always make it a habit to keep the minimum fasted time of 22-23 hours between feedings.
As a bodybuilder used to 6+ meals a day I was somewhat skeptical I could make gains on such a protocol and I did find in the short term my strength levels suffered. After 4-6 weeks however my body really adapted and my workouts were even more productive than ever. Great energy, pumps and strength/muscle gains on par with my 6 meal a day protocol but without storing excess body fat. I think a lot of bodybuilders who try OMAD and complain about loss of strength perhaps haven't given it a fair shot. A fair go would be at least a 3 month trial and of course ensuring you get your calories in even if that means a 2 hour feeding window.
Hey man. I would like to ask, how many calories per day do you eat in that 2 hour window? :) not sure how getting in around 3k calories is possible when you workout every day and are geneticaly rather skinny
@@medicvlogs4110 My intake is typically between 2-3k. I don't think it's that difficult to consume 3k calories but everyone is different. You could try including high calorie shakes or extend the feeding time to a 3-4 hour window with an hour break between meals. I doubt there's going to be much difference in terms of the benefits seen from a 20 hour vs 23 hour fast. You want to find a schedule that works best for you so you're more likely to stick to it.
How often do you have bowel movements?
@@plumeria66 daily, usually right around meal time
@@dune7824 That’s great. I read many people get slower digestion and bm’s less frequently with OMAD. Why is the window for eating so important? I’m not trying to lose weight but to maintain or gain weight. A big meal takes me 3 hours to eat. I’m doing two meals a day because of slow digestion which causes me bloating and feeling full all the time. Am thinking of OMAD to give my digestion time to help process all that food even more.
As a construction worker I started practicing this and got fired because it decreased my performance. But at least, I am still young.
The stomach needs to rest in order to slow down aging!! Once a day is not easy for most people. twice a day is possible for most and it is better to start doing 2 a day first~~
He says to put our bodies in a defense state like whales do and mice don't.
I would think that mice are constantly in a defense state being a prey for so many hunters.
I knew it!!! So it wasn't just me. Over time I always look younger when I ate 1 meal a day. My face looks younger with fewer lines but when I eat normally I look older.
what's more important for longevity, calorie restriction, or time in a fast? Being an athlete, I am much more open to simply condensing my calorie intake into a smaller window than reducing my calorie total intake. It seems both methods work but I haven't heard anything that compares them.
despite what many gurus sell us, we simply do not have that information for long term. we do know calorie restriction works and that's it. it's the only robust long term data we have for health span. fasting does calorie restriction automatically so it might just be that for long term health. but anecdotally people feel amazing on it probably because their bodies aren't being taxed processing food all the time.
Long term moderate caloric restriction with nutrient excellence is shown to be best for longevity. Fasting can be used as a good tool to moderately restrict your caloric intake. The key is then eating nutrient dense food. Athletes are gonna require more calories by nature they are burning more. Fasting can still be a great tool if you want to lean up and in some workouts it actually helps. But in competition phase or really intense workouts up the calories try to eat before too especially some good carbohydrates.
what he is saying is very true. ive done this for years and im in my 30s. i look and feel like a high school senior.
I started cutting(trying) down couple days ago... Yep,time really slows down. I usually fill up on water tho. I noticed that after waking up and having plans for the day,once I have breakfast I feel heavy all the conviction of the early hours almost completely disappears;anyhoo I'm trying to get to 1 meal a day from 3 sometimes 4 with snacks in between. I'm down to 2 meals with no snacks and just alotta water.
Well,what do I know?!?
Any ideas on if this is doable for someone who works a physically demanding job all day? I.e. a mail man?
try it and see if it works for you
Perfect explanation love it
Who are the sources saying that drinking (black cofee and tea) takes you out of fasting state? All the sources I've read seem to suggest that this isn't the case.
This is true only for non acti e athletic people. If you are training heavily in some area you need to eat at least 2 meals. I'm sure there are exceptions but for optimal output for say a spartan race training, you need 2 meals a day no question about it. These diet are typically to be implemented for historically sedentary people or past heavy physical activity age.
Lies , lies and More lies. My energy levels are insane when I fast . I’m never tired , I wake up with the most energy and it lasts until I eat my first meal . I been pumping in the gym , running and getting my cardio in before I eat and I feel fucking great .
I have no clue how people do these fasts without losing way too much weight cause thats what happened to me when I did it.
Is OMAD the same thing as doing 24 hour fast?
Are there ANY human studies that show OMAD or any other type of meal timing/restriction has any affect on longevity? Cause i cant find a single one. But i can find plenty of studies showing plain old calorie restriction works just as well
How are you going to meet your daily nutrient intake with just one meal/day?
before or after exercise?
Explain the weight loss, what to do about all the weight loss.
If I don’t eat for a long period of time my blood pressure drops and feel dizzy. This is not for everyone
Starving children in Africa beg to differ
Fasting for kids and young adults isn’t so good cause they require so much energy but for older pple it’s amazing
I disagree.
But what if you lift tho? will you still get the gains??
This is what I was wondering too. I watched a video on intermittent fasting from Dr. Eric Berg and he mentioned that what matters is how often you eat and not necessarily how much you eat. So I'm assuming this means you would just have to eat a lot of calories in your one meal, or maybe try a short window of a few hours to get your daily calories? Hopefully someone knowledgeable in this can answer this.
I eat one meal every other day to help manage IBS. I can’t imagine eating only one meal every single day
why not.. you are doing it every other day.. its the same fucking thing..
This is the dumbest thing I have read all day
I fasted for 3 weeks once
I agree one meal a day is best... intermittent fasting
Ive been eating one a day for 20 years. At 50, Ive recently shoveled 1.5 triaxles of gravel....just sayin.
It's time saving too 👍
May I ask what you usually eat, and what size portions? And do you literally only consume anything with calories once per day, or do you also eat fruit, drink shakes, have coffee with milk, or anything else with calories?
I'm asking because I'm very interested in trying this.
- Cheers.
@@andthereisntone3454 there are other videos of him talking about it. Check em out👍
@@alexmason8557 I was specifically asking Nobody Nelson, just to hear his personal experience. But cheers.
@@andthereisntone3454 LOL... Im almost embarrassed to answer. I sip a large coffee that lasts all day to go along with my 20 cigs and 3 joints, maybe a donut or apple but rarely. Then after work I eat maybe 10 or 20,000 calories of pizza, burgers, massive salads, lasagnas......about a three or 4 lb meal. Im no health nut, three meals a day just never made any sense to me ....evolutionarily;). NOTE: I usually do very physical work/play. and burn alot of calories.
I would now ask that you all take the opportunity to think long and hard about this sentence, I'm now over 40 years old and i would have loved to experience loyalty and commitment from a women. Even though this is the case I would still NEVER be interested in manufacturing such things... if it does not happen its not meant to happen.
I intermittent fast cause I’m poor and I gotta say with how much weed I smoke I don’t notice an energy difference.
But when I do eat, that food coma hits
I do this a lot. But how do you not lose weight and become too skinny ?
Does anyone know how you’re able to maintain muscle mass and only eat once per day? Do you literally eat all of your calories in one sitting in one huge meal? I guess that’s literally the only way but doesn’t seem very practical.
If you drink milk drinks during the day you can get some protein and energy plus I add matcha and coffee to give energy
thank you
I guess this is why I'm 23 and I still look like I'm 15.
Milk?
I wonder there are so many vids for this, but what about the vitamins and minerals how to even get that in one meal?
Also you know that today's food are so un-natrual mostly they are mixed with chemicals to grow things fast, so again what about the daily vitamins and minerals intake?
Wont this be bad in long term?
Then there's supplement, are those even good enough?
Diet sodas?
Im trying this now and it feels right. It feels real. The energy that is created is different. My question is, can i do est like shit on the weekend and one meal a day during the week and get lots of benefits still? 😅😂
It would be interesting to see the scientific data behind intermittent fasting.
I just started about couple weeks ago and my goal is to see the results in 2 to 3 months. If it works go 6 months.
How did it go?
So I can have milk in my tea in the morning and it won't counteract the anti-aging benefits?
Is it possible to gain weight while having 1-2 meals a day? Do they eat the calories of 3 meals in one? Or truly 1 serving size meal / day??
@@jasonbarton2084 exacly people love not to use the Brain nowadays. So Many crazy questions. Its all about calories
Will this only benefit the young or, can this be applied with mediocre results for people in their late 30s to mid 40s let's say?
You can start this at any age. Take care
He is in his 50s
I've done a lot of fasts, few days without food and felt like shit afterwards. But then again, I did a lot of drugs
OMAD needs to be qualified with ensuring you meet your protein needs so you don't lose muscle mass and eating earlier in the day
Great, advice for humans based on data from yeast, mice and whales. I also suggest jumping off a cliff and bouncing your arms around to fly, and I've got data from birds to back me up here.
Silly goos
Great. Most medical labs are bs and should be shut down according to you.

It works in primates as well, bud.

I often find David Sinclair annoying but he's spot on about habit. Eating frequently and snacking are merely habits, in this case deadly habits, but habits can be changed. I eat intuitively these days, without rigid rules or expectations, so some days I eat more or less, but I do notice that a slightly empty stomach feels way better than a stuffed one. The body has its own wisdom, for sure.
Why do you find him annoying? Misinformation?
@@sadbravesfan he repeats weak and poor 'science' from nutritional epidemiology and his authority as a scientist gives it weight. it's frustrating
Skipping breakfast is bad idea because it misses the prime time for digestion:
a) stomach meridian is most active between 7 to 9 am and
b) spleen meridian active between 9 to 11am.
Better to skip dinner as the small intestine meridian, which is last in the digestion process, is active between 1 to 3pm. Cheers.
So our stomachs are adjusted to the time of the day? Lol. Is this EST time? Haha
You're totally not correct. Sorry to say.
@@Skipxl No, don't listen to this person.
But people keep telling me they become seriously depressed after going OMAD for a while...
Try working a full time job and a part time job like I do on one meal a day. I guess he’s privileged to be able to do so?
Nah learn about nutrition and consume foods that digest slowly.
@Ross Karr - You’re confusing OMAD with skipping the Caloric content of the other 2 Meals. Those on OMAD consume 3 Meals worth of Calories in a single shorter time window, often 6 Hours or less. They have also adapted to primarily burning Fat (Ketones) for energy, rather than Glucose.
The advantage is your Body’s Glycogen Store is relatively small, only about 2500 Calories, while the Fat Store can be 200,000 Calories or more. If you are Carbohydrate-Adapted, you must constantly refill your Glycogen Store during the Day or run out of easily available energy. If you’ve become more adapted to burning Fat by drastically limiting the Carbohydrates you consume, you’re using a larger “fuel tank” and don’t need to refill it as often to maintain your energy level.
@@andrewstrakele6815 2.5k or less calories is fine depending on what you do. By all means use fats instead of carbs for your energy source if you want to exceed that. There still neurological reasons to consume liquid carbs throughout the day, so fixate it at your peril.
@@qx-jd9mh - Actually, Carbohydrate consumption is completely unnecessary. The Liver can manufacture all the Glucose your Body needs from Protein or Ketone substrates. There are no essential Carbohydrates. In addition, the Brain loves using Ketones for energy to spare Glucose usage. It is the reason Ketogenic Diets are useful in the treatment of a whole host of Neurological conditions.
@@andrewstrakele6815 Your brain can supplement glucose, not replace it. Lmao keto diets are horrible for your brain; just because they can be effective at treating some conditions doesn't mean you should use them. Look at some medical research publications like PMC3900881
drinking milk can easily break the fast. dairy contains calories and carbs/sugar.
No offense dude, but always looking down with a pen in your hand doesn’t make you look smart, it makes you look pretentious and unlikable.
as much as I want this OMAD but I work in a skilled job, even at thrice a day eating I get skinny when active.

Eat complex carbs. It will fill you up good.
@@frog6054 Rubbish. Eat fat and protein, your body only gives hunger signals if it's nutrient deficient. Carbs are not essential to humans.
