Life is complicated, and that means it's common to experience a setback in weight-loss goals. Don't rely on sheer willpower to get you through the rough patches, and don't give up altogether. Instead, forgive yourself and pick up where you left off. Problem solve. Figure out why you slipped and find solutions for the next time you face dietary temptations. Get support from family and friends. And review and recommit to your weight-loss goals.
