basically the idea of eating one big meal every day instead of 2-3 smaller ones. I like the idea of making like, some eggs, or something in the morning and eating a big ol' meal with all of the nutrients i need at like 3:30. and then like, some fruit as a desert. is this healthy?
Generally yes. It can vary depending on a person's specific circumstances and what kind of health issues they have and what they're trying to accomplish. But by and large, reasonable intermittent fasting (like OMAD) can be very healthy and helpful for people.
edit: I wrote quite a bit in this older thread defending it against a naysayer if you're interested.
