Yes. Not because I want to lose weight, but so I don't gain, and also try to pack in as much fruits and veggies and whole grains as possible for optimum health. Also to help offset any junk I do eat.
Have you ever been out with a member of the opposite sex (or same sex, depending) and weren't sure if it was "just as friends" or a date? (just so you know this didn't happen to me recently as I'm married!)
