And since you planned things out, you'll actually get the protein, fruit, and veggies your body needs — and you'll lose weight in the process. Eating sugary foods might be satisfying in the moment, but they can increase your cravings for more sugary foods in the future — and that only leads to trouble. If you've plateaued in your weight loss plan, try these simple, expert-approved tricks that boost metabolism and burn fat — no crazy diets or weird workouts required.
