Frequently Asked Questions

  1. What is DietPower?
    A health tool for your computer. DietPower is the world's most effective and user-friendly nutrition software, designed to help you balance your diet and master any weight problem permanently. It's also the only diet program that can guarantee success.
  2. How does it work?
    By helping you "Eat With Your Eyes Open"™. DietPower shows you instantly how each food and exercise choice will affect your progress toward your goals. It also gives you daily targets—and clear advice on meeting them.
  3. What's the main difference between DietPower and other weight-management systems?
    Confidence. Other systems don't track you evenly toward your goal—they only estimate where you'll be at the end of your diet. Our Calorie Feedback™ feature ensures that you'll reach your goal on the date you select. Meanwhile, our Food Coach can show you which of your favorite foods is best to eat right now—something no other program can do.
  4. What do I eat?
    Anything you want. You can use DietPower with the same foods you enjoy eating now—or with Weight Watchers, the Zone Diet, the Atkins Diet, Slim-Fast, the South Beach Diet, or any other weight-loss system.
  5. Does it work with diet pills?
    Yes, with any drug or supplement, including Alli, Meridia, Xenical, and hundreds of others. If a medication alters your calorie needs, DietPower automatically adjusts your daily budgets accordingly.
  6. Will I be hungry?
    Not if you don't want to be. Although DietPower works accurately at any speed, it's especially good for losing weight slowly, by improving your nutrient balance instead of slashing your calorie intake. (For permanent weight loss, experts recommend losing no more than two pounds a week.)
  7. Is it hard to learn?
    No—it's remarkably easy. The user interface was designed by a top editor of Reader's Digest, skilled at translating medical science into plain English. Our animated tutorials can make you an expert in minutes.
  8. What's a typical day like?
    Just like before, but without the guesswork.

    In the morning, you open DietPower and key in your weight. The program shows you "Food for Thought," a bit of advice and inspiration tailored to your goal. Meanwhile, the program adjusts your calorie budget by comparing your new weight with your recent meals and exercise. The adjustment is usually only a few points, but it guarantees reaching your goal weight on your target date.

    With an eye on today's budget, you log your breakfast foods. Let's say you're having Cheerios, milk, and strawberries this morning. As you drag these from the Food Dictionary into your log, their calories show up in the Scoreboard on the left side of your screen. Meanwhile, 32 other nutrients are being tallied in your Nutrient History.

    Looking at the Scoreboard, you're pleased to see that you got only 15% of your calories from fat this morning. But your Calorie Bank is in the red by 1554, meaning you've overeaten by 1554 calories since the beginning of your diet. That's almost half a pound. You decide to be careful at lunch.

    At the office, somebody orders Pizza Hut pizza—two kinds, Pepperoni Pan and Chicken Supreme. Looking these up in DietPower, you discover that Chicken Supreme gets only 27 percent of its calories from fat, versus 42 percent for Pepperoni Pan. Wisely, you choose the former.

    Thanks to this decision and a 20-minute walk that awarded you 108 extra calories, you arrive home feeling confident that dinner will be a success. Sitting down to your computer, you import your DietPower records from an email you sent yourself before leaving the office. Your Food Coach says that you're low in vitamin A, and that one of the A-rich foods you like is broccoli. After logging a cup of broccoli, you look up lasagna and are delighted to see that one serving will raise your Nutrition Quotient by eight points. With help like this at your fingertips, you sit down to dinner knowing exactly what is right for your goals.

    Knowledge isn't the only thing you need to make a diet successful, of course. But knowledge is better than ignorance. Because it's easy to fall off the wagon when you're riding in the dark.
  9. Do I have to weigh myself every day?
    Not at all. You can log your actual weight once a week, once a month—whenever you like. On days when you don't record your weight, DietPower simply assumes that your weight hasn't changed. When you finally do weigh in, the program immediately brings your calorie budget up to date. (If you'd rather use a constant calorie budget, you can do that instead.)
  10. Won't logging my foods take a lot of time?
    No. DietPower's Food Dictionary offers four different search methods that can find almost any item instantly. After a couple of days' experience, most people can log a meal in less than two minutes.
  11. What about recipes?
    You'll love this. Besides starting you off with 100 scrumptious recipes, DietPower lets you add as many as you want, complete with directions in case you want to print them for friends. Each printout includes a nutrient profile. Fold on the dotted line and the printout becomes a 4"-by-6" recipe card. (You can also email your recipes to anyone.)
  12. Can DietPower help me gain weight?
    Certainly. Just choose a goal higher than your current weight. DietPower works either way.
  13. How about weight maintenance?
    That's easy, too: set a goal equal to your present weight.
  14. Is the program medically sound?
    You bet. DietPower has been developed over a period of 18 years in consultation with leading experts on nutrition, weight loss, exercise physiology, and behavioral science—all of them published in peer-reviewed scientific journals. The program has been carefully checked for accuracy.
  15. What do the critics say?
    A few excerpts:

    "It's truly fantastic—the best thing I've seen for getting an instant picture of your nutritional status and how to fix it. As a computer klutz, I found the program amazingly easy to use. Even for a pro, it's an eye-opener." (Jean Carper, syndicated nutrition columnist and author of the bestselling book Food Pharmacy)

    "A powerful tool for self-management." (Robert Epstein, founder and director emeritus, Cambridge Center for Behavioral Studies)

    "4 Stars!" (Shape magazine)

    "I used DietPower to lose 25 pounds while preparing for heart surgery. It worked well—I actually enjoyed dieting!" (Business manager in Gaithersburg, Md.)

    "After gaining 20 pounds during my divorce, I finally discovered DietPower. It's turned my life around. Not only am I slim and trim for the first time in years, but I've finally found my true love. We were married in October." (Executive in Princeton, N.J.)
