How do kpop idols dance and perform for hours with a meagre diet?

I think they just get used to it after years of training and of course it's still hard but not as hard as before they were trainees, they probably also take vitamins to make sure they are sufficiantly healthy but also not gaining weight, and they drink lots of water and probably some energy drinks

Once you are on a diet for a long time, you get used to it, or most do, sometimes it's still hard but not as bad as it was

I have no idea as well, if I don't eat properly I can't do shit without passing out

thats beyond me too, how can they that energize and full of life everytime while having a strict diet

and here i am cant even think straight when im hungry

I think they probably eat more than we think and burn it all off, it's like if you're in the Army you can be eating 5000 calories a day but don't get fat as you are working it all off.
