"You really want to have your head together and give yourself the best chance you can," says Carrie Wiatt, nutritionist and owner of Los Angeles-based nutrition-counseling firm Diet Designs, Inc. Weight-loss is a lifelong commitment, so you'll have to be ready to make some big changes. Start with the simple things, like limiting the accessibility of your binge-eating trigger foods, cutting back on alcohol, and keeping a food and exercise diary; if you're not exercising, add a brisk evening walk to your daily routine. Most importantly, lose weight because you want to, not because it's expected of you.
