Number of meals are very individual. I must do OMAD, for example or else I will eat way too much, I can’t avoid that.
I imagine the OP has a high enough energy need to be okay with 2 meals especially that it’s clearly not like my case where a small, 1200 kcal meal typically just makes me hungrier
But OMAD is perfectly fine if it suits the one in question and one doesn’t need to be fat adapted or in ketosis to do it, many on high-carb do it too, it’s individual. My fasting abilities didn’t get any better when I went keto and got fat adapted, in the contrary for a while when I got satiated way too easily, fortunately that passed. Now I can do OMAD most of the time, not all the time with any amount of carbs though it’s usually way easier on higher-carb.
