World's Best Weight-Loss Software!

Try FREE or Buy With 1-Year No-Hassle 100%-Back Warranty

Diet Power is the only weight-loss software that guarantees reaching your goal on your target date. Our award-winning program makes any diet* more powerful by managing what all diets have in common: calories. It also helps you control your nutrient balance.

Unlike other programs, Diet Power "learns" your metabolism by monitoring how your meals and exercise affect your weight. It also improves your balance of 33 vitamins and minerals by recommending foods you like. It even calcuates a Nutrition Quotient™ showing how smart an eater you've been. No other program does any of this.

Our software's extraordinarily deep personalization has evolved since 1988 under the guidance of leading experts in nutrition, physiology, and behavioral science. But the program has also been tweaked by ordinary users demanding lightning-fast performance. That's why weight watchers around the world rate our diet software the best.

Besides Counting Calories…

…Diet Power shows nutrition facts for 11,000 foods (including 2500 fast foods); tracks calories burned in exercise; helps you fight heart disease, diabetes, cancer, stroke, and other nutrition-related maladies; plans menus; charts body measurements; "doctors" recipes for healthy weight loss; delivers personalized nutrition news and features; lets you meet other weight watchers online; and a lot more…
