This is the screen you see when you first enroll in Diet Power. The row of buttons at the top is your gateway to all of the program's features. (You can change your Home Screen to display a graph of your Body History.)

Diet Power starts by asking your name, age, height, and special health concerns and interests. These help the program set up your files and begin customizing your nutrient requirements.

Here's a partial view of the Ideal Weight screen, showing one woman's results.

Designing a diet is easy. Just click the red arrows to adjust the time span; then drag the blue paddle toward your desired weight. Meanwhile, watch the red figures at the bottom—they tell how difficult the diet will be.

Before adopting a diet, you can read what the diet will be like. This example is for a person who wants to lose weight at a moderate pace.

To record meals, simply drag foods out of the dictionary at the top and drop them into the list at the bottom. You can also do "what-ifs" by watching the color-coded nutrient window that opens when you click a food.

Although it already lists 11,000 foods under 21,000 names, the Food Dictionary will let you add an unlimited number of your own, by keying in information from labels.

You can also add as many recipes as you like, complete with directions and nutrient analyses. (You can "doctor" any recipe by copying it and revising the ingredients.)
