How do I gain weight? I eat a lot but I'm gaining none. I read that eating sugary foods result in weight gain, which I used to eat like real high but my body is still the same even after I'm done with regular exercise. Now due to eczema breakouts on my neck and forehead I gave up on all sweet stuffs, and try to maintain a simple diet. Being so skinny has become real heavy to be calm when the thought put me under so much stress, that I  can't focus on anything. Can you suggest me any ways to put on weight...?
