If you starve yourself and lose weight will your stomach be flabby?
Certainly wont be the tight hip stomach you are looking for, no.
Im a 16 year old 5'3'' female that weighs 155 if i starve yourself for a week how much weight can i lose?
Weight can be gained indirectly by starving yourself. Starving yourself increases the likelihood of binge eating so weight may be gained that way. The body also begins to regulate itself so that it loses weight more slowly and gains weight faster when you starve yourself. It is sort of like a protection system to stop the body from being damaged when it cannot get the fuel it needs.
I don't think that you should starve yourself if you're trying to lose weight. Actually, you shouldn't starve yourself for anything. If you're doing this to lose weight, you should try eating a little bit less and exercising a little bit more. There are also foods that you can eat, like whole grains, that stall your hunger, making you not eat as much.
