Be picky, picky, picky

Peruse the buffet before you load your plate to avoid foods you don't really want, suggests obesity expert Tim Church, MD, a professor at Pennington Biomedical Research Center at Louisiana State University. If, for instance, you could take or leave sushi but adore sliders, don't start with the tuna rolls hoping to be able to resist the two-bite burger.

"If you pick the stuff you really want and have it in moderation," Dr. Church notes, "you'll stave off those cravings that can get you in trouble later on."
