I don't understand it, either. When I'm tempted to overindulge, all I have to do is think of the looks I get from men (still, at age 44!), or the pleasure of seeing myself in the mirror looking trim and cute/sexy and knowing that I can walk around with my arms and legs exposed without shame or embarrassment. No dessert or snack in the world, not even peanut butter cups (tee hee!), is more enjoyable than that.
