That is probably because you are in your mid 30s. 50 is when is goes the other way. Menopause doesn't care how much you exercise and eat right, your body goes through a lot of physical changes, and they aren't pretty. Skin sags, weight shows up in weird places, everything gets dry and loses color. While men, as long as they do a small amount of exercise, tend not to change much. Unless they go bald, but even that has a certain following. I personally say screw worrying about how you look, and focus on your heart and mind aging well.
