Goal Diet is gimmick free -- no grapefruit, popcorn, or weird magical weight-loss berries here. Goal Diet's plans are based on the scientific truth that weight loss is only achievable by consuming fewer calories than you use, forcing your body to convert fat into energy.

It sounds simple, and it is, but there are some sophisticated calculations behind it all. Goal Diet uses medically proven formulas to measure how much energy you use, factors in your goals, and provides science-based budgets to realistically guide your diet and exercise efforts.

You can plan a steady diet with monthly goals, or create a plan based on achieving your goal by a target date. You'll also find formulas like BMI, BFP, and Ideal Weight to help you determine what goals are best for you, plus exercise calculators, a useful strategy guide, and more.

Important note: always consult your doctor before beginning any diet or exercise plan. See the Strategy section for more useful tips.
