Keep your list handy so you can reach for it when the urge to indulge strikes. Regularly reward yourself with nonfood items. Choose afternoon snacks that are a combination of carbohydrate and protein. If you know that you can't limit yourself to a standard serving of frozen yogurt, don't tempt fate by keeping a half-gallon container in the freezer. Give cravings a workout.
Exercise is known to reduce stress, improve mood and decrease appetite.
Walk briskly enough that your heart rate increases and your breathing quickens, yet at a rate that allows you to carry on a conversation while walking. Always walk at a pace that is comfortable for you. Instead of taking one longer walk, you can take two shorter ones. Find a walking buddy. It's a great way to stay motivated.
