DAY EIGHT: SNACK SUGAR-FREE

Satisfy your sweet tooth with sugar-free snacks. Kirstie Alley told PEOPLE that low-calorie Jell-O with Cool Whip Free is "the greatest invention," and Heroes star Greg Grunberg swears by sugar-free popsicles. "If you're looking to lose weight, sugar-free snacks can make a difference," says Pachella. "It's a way to indulge in 'mindless munching' minus the damage." But, be warned, too many sugar-free treats can lead to excessive gas, bloating or cramps.
