I'm 19 years old, 5'4" or 5'5", 120 lbs. Recently I have been jobless, lazy, and an excessive eater. A year ago I was in perfect shape. Now my muscle has turned mostly into fat. I'm not looking to lose pounds, just turn my fat back into muscle. My biggest reason for changing my diet and getting fit is to change my life to prepare me to quit smoking. I want to quit for good and I want to prevent the problem I had last time which was that I gained so much flab when I quit smoking that I started smoking again to lose the weight back. That idea wasn't prefect.
