weight gain problem

You don't want to eat unhealthy food in an effort to gain weight, because even if you can't see it on the outside, it will be making you sick (raising your cholesterol and blood sugar). If you are looking for nice curves, do lots of squats to build up your rear and give you a nice round bum. I have the opposite problem that you do, and a lesson I learned is to date guys who find my figure perfect just the way it is, rather than trying to "improve" my figure to catch someone else's eye.

i'm interested in this matter to, i'm like you, i'm 1,75m and i'm only 49 Kg, i eat a lot, and every food also fill of fat and shugar, but i don't gain weight, maybe it's a problem, maybe not, think about who is fat, and eat less than you, they have the opposite problem, but i think is better be like us than like them.
