Can gain weight w/o: If one is truly underweight (based on height, family background, and body type), a Dr. can evaluate for a hormonal, digestive, or other disorder. If no medical cause is found, then one can add weight by eating more calories of nutritious foods (can gain weight without medications). Add protein: egg white, chicken breast, salmon,... Better fats: olive oil, peanuts, almonds, tofu,....
