I am on Ritalin right now for my ADHD, and I have gained definition in about 2 weeks, but I was wondering that due to the fact that Ritalin suppresses appetite a great deal, am I losing muscle mass because of this, or has my body been tricked into thinking it is full so it only eats away adipose tissue, sort of like what leptin does? I would like to lose my bodyfat but I don't want to lose muscle, I need a workout and diet to help me keep my muscle mass, Please Help, Email Me at [email protected]
