My husband, who was overweight for the first ten years of our marriage, became a vegetarian for personal, ethical and religious reasons rather than health reasons about four years ago, and began to slowly lose weight. Then in the last couple of years to return to the activities of his adolescence and youth -- especially distance running. The pounds just slid off of him. He is now quite fit and slim, but continues to have this self image as a "fat tub of goo."
Here's a picture taken today, with him wearing a t-shirt about three sizes too big, and warm-up pants at least one size too big because I can't get him to buy new clothes that fit. Surely any reasonable person would agree that this is a person who is fit not fat!
