MyDiet helps you to set and achieve your nutrition and fitness goals. MyDiet applies a scientifically proven approach to weight loss: Eat less, exercise more. To lose weight, you must consume fewer calories than your body burns. It seems simple. But how much less? And how do you know you are achieving the proper levels of nutrition and exercise? MyDiet provides the support and information you need, all in the palm of your hand. The Goal Wizard helps you set a daily calorie budget, based on your personal metabolism (calculated using the scientifically validated Harris-Benedict algorithms), weight-loss goals, and exercise level. Daily Meal and Exercise logging help you stay on track with your program. The handy MyDiet Today page gives you instant information on your daily activities, so that you can stay on target. The Weight Log and Chart provides positive reinforcement on progress towards your goal. MyDiet is scientifically based throughout. Goal setting uses the Harris-Benedict algorithms to determine your metabolic rate based on your personal profile. Exercise logging uses data from the CCC to determine calories spent on over 50 diverse exercise activities, including aerobics, weight training, dancing, tennis, and many more. Exercise calories are calculated based on your profile (for example, a 200 pound man will burn more calories playing tennis than a 110 pound woman).
