Slim up your snack Its hard to avoid that 3 p.m. stomach rumble, when nothing can stand between you and the office vending machine. And while its fine to eat something to hold you over until dinner (in fact, we encourage it!), some choices will help you keep on your weight-loss track—while others can surely derail you. So at the vending machine, instead of choosing that ever-so-tempting pack of Twizzlers, try a 100-calorie cookie pack or a Nature Valley granola bar. Better yet, bring a snack from home! Were fans of sliced veggies dipped in hummus. Delish!
