Any one doing the OMAD diet ( One Meal a Day ) in I'm Too Fat Forum Posted March 15 On 3/11/2021 at 2:24 PM, jackdd said: I can understand how it might work for somebody trying to lose weight, but what you describe doesn't make sense. Eating many small meals would be what would result in stable levels. After eating your one giant meal a day your energy levels go up to the roof, and then after your body digested this it goes into starvation mode until the next meal, this is the opposite of stable. You say you don't do it for weight loss, and are doing it since ten years, so obviously your one meal has to cover your maintenance calorie level. I assume you are a normal man, this would probably be about 2500 kcal. How do you eat 2500 kcal in one meal? With just junk food I might see how this is possible (still difficult though), but if you also want to get a decent amount of protein, and micro nutrients (vegetables, fruits...) in, I would say that's impossible to do. What do you eat for your OMAD? I'll have to give my "broscience" explanation because I'm no scientist & basically just followed the basic guidelines from a book called the "Warrior Diet" by Ori Hofmekler. From what I recall, having read it over 10 years ago, after an initial few weeks the body shifts/swaps the leptin/ghrelin (paraphrasing here) & the body is no longer in starvation mode during the day. I can only speak from my own experience but for myself I only experienced mild hunger for a few days before the shift/swap etc. It's arguable whether I'm a normal man but that aside, I eat until I'm full. I can usually eat between 3-4 chicken breasts/thighs, a big salad, 1.5-2 small containers of sour cream, butter, cheese (probably only once a week), "cloud bread" & I'm pretty much done. When I was in Australia I ate more beef & whatever vegetables/salads were in season. I also tend to eat more cheese when I'm there, perhaps 3-4 times a week. I'm not sure if how I eat is supposed to be possible/impossible but it works for me. I get a full health check twice/year & though my doctor here thinks I'm a bit crazy, though that may just be me not my diet, apparently everything is good. Same with my doctor in Australia. I'm not one to recommend/not recommend diets of any sort, aside from (in general) avoiding junk food. I'm just sharing my experience on the OMAD but I'd guesstimate that it's not for everyone & only really talk about it if asked, or if there's a thread asking about it such as this one. If anyone expresses interest in IF/OMAD though I always encourage them to be open to the different forms of IF because from my experience & that of friends there are a lot of variables that come into play that & for whatever reason some forms of IF work better for others & some really just don't. For what its worth I'm also a life long martial artist, which is one of the reasons that I was interested in sustained, stable focus/energy & for me I like that I can train at anytime during the day & feel ready to train within 30-45 mins after my one meal as well.
