Liposuction physically removes your fat cells. Without fat cells you cant get fat. It doesnt matter how much you eat. Fat cells dont reproduce, when you get fat its just the same cells storing more fat. Naturally thin people like the japanese just have less fat cells. Women and men have a different distribution of cells, such that a thin woman will still have fat on her butt and breasts.
