Eating only one meal a day might not make you any thinner. I mostly eat one meal a day, and I am a stable 5-8kg overweight. However you eat, make sure that you get the required nutrients and calories your body needs.

2, how is this a question? I'd ideally have 4, but what'cha gonna do?

One meal a day is not good for the human body. Instead, it's best to take in smaller amounts of food over larger time periods, thus why two/three meals is common throughout the world.

You do whichever one gives you sufficient calories and NUTRITION to survive. It already sounds like your OMAD plan doesn't do that is you're shedding pounds and would be "extremely thin". That's not good.

I eat one giant meal. I don’t like to exercise while full and my buddies come over to go mtbing during the day sometimes so I just eat a big meal at night. Make sure it’s balanced and you’ll do fine.

I usually have 3, so I'd choose 2. I can't imagine functioning the whole day on one meal.

2, I don't have enough stomach space for the bare minimum calories needed in a day all in one go. Must be two.

Two meals because sometimes I just need a boost.

I assumed everyone's body makes adjustments for what it needs. For me personally, I just got used to one meal a day. I got to an ideal weight and doubt I'll lose more unless I increase my exercise. I also eat both heavy meals and lighter meals, it just depends on how hungry I am on a given day.

Have been doing 2 without really realizing it for the last year or so. It’s been steady as far as weight loss goes since for the most part it’s just calories in calories out with some exercise sprinkled in. Now, I don’t know if OMAD would make you actually thin or it’s still a question of CICO but just go with whatever feels natural to you, don’t force yourself into a single lifestyle till the end of days just because you decide something tomorrow. Life ebbs and flows, and so do your habits and the adjustments they may require. Good luck!

I greatly prefer 1 meal a day
