I know what you mean about why should you weigh more just because you are older. I feel the same way. I'm 33. I don't want to "age" like traditional women do and gain weight. I feel like being skinny is the good thing to be. I like to tell my self when I restrict that it's healthy. I know its not. It affects my heart and muscles and arthritis. I may be skinny and "young" on the outside, but inside it's making my body age so much older.
