What All Diets Have in Common

Gas pump manThe human body, for all its wonderful complexity, is still a machine. It burns fuel (calories) to do work (moving and thinking). The fuel must be correctly formulated (nutritionally balanced), or the machine will run poorly. The mileage (calorie burn rate) depends on the year, make, and model (age, sex, and individual).

Unlike ordinary machines, however, your body can accept a huge surplus of fuel by converting it into fat.

All diets work by making your body burn off this fat reserve. To lose weight, you must expend more calories than you eat. There's no exception to this rule; it's a law of physics.

Diets differ only in how they tune the engine. Low-fat diets substitute a leaner fuel—mostly vegetables, fruits, and grains, which contain fewer calories than fatty foods. The Zone Diet makes the engine burn "hotter." (Exercise does the same thing.) A few diets (and most diet drugs) fool the machine into burning fuel wastefully or demanding less than it needs.

These are clever solutions. Yet most people who lose weight eventually regain it. Why?

Meet the Governor

Download DietPower free trialNo diet can succeed if you shed pounds too fast. (Most experts recommend losing no more than two pounds a week). When you starve the engine of fuel, it responds by increasing its fuel efficiency. Suddenly, even skimpy meals feed your fat reserves. If you cut back even further, your body becomes even more efficient. Repeat the cycle and you become a "yo-yo dieter."

What you need is a "governor" that keeps the engine running at perfectly even efficiency. That's what DietPower is. It shows exactly how fast your body is using fuel, so you can eat the right amount to keep the fat reserve shrinking at a constant rate. By smoothing the fluctuations, it keeps you precisely on target.

Eat by Number

Read about the Food LogRead about the Food DictionarySusan uses her Nutrient History to help control her blood pressure. After lunch one afternoon, she clicks the Food Log button (far left) to record the meal, and discovers she's getting too little potassium today. To plan dinner, she clicks the Food Dictionary button (left) and searches 21,000 entries for items that are high in potassium but low in sodium. Voilà!  The best choice is grilled salmon with a baked potato—and for dessert, fresh cantaloupe.

These nutrient-tracking features help in myriad ways:
