Any secrets?

EAT! No, seriously, EAT. The best thing is 6 small meals a day. Also, if you do a sport, or some kind of exercise, like going ot the gym, or running around a track (if you had one nearby, that would make that part easier ), do that. Just be active for at least 30 minutes a day.

Um, for food...Kalen mentioned organic foods, which is an excellent suggestion. Stay away from too much bread/potatos, load up on vegetables---I'm sure there's at least one that everyone likes.

That's the best advice I can give on the spot, since I don't know you presonally, or what might work best for you.
