Not really, Im one of those nauseating people who eats and never gains weight (ducks because I know people are throwing things:P) I am grateful to have been blessed with good genes, my mom looks great at 59, and is still around the weight she was in her 20s (and thats after 3 kids, with my brother being 13 lbs at birth..ouch!) I do swim if I get the time, but no structured exercise.
