So ive got what i think is a huge problem. I am 16 years old and weighing at about 95 pounds. My ribcage is showing very clearly. I have been drinking smoothies with protein, strawberries, and almond milk every morning and every night. Ive been eating regularly. I just cant gain that weight back. I really feel bad about myself and need to put on weight. I just dont know how. If someone could give me tips and tell me if i should go see my GI doctor then that qould be great.
