Although there are many weight-loss diets, statistics show that most people who lose weight on a diet regain that weight, and sometimes gain more. The best ways to stay healthy are eating well and being physically active.

Very low-fat diets do not follow the USDA guidelines for healthy eating.

The low-fat eating concept limits eating fats that can lead to weight gain, high cholesterol levels, and heart disease.

You do need some fat in your diet for energy and to help absorb vitamins. Popular low-fat programs such as the Life Choice Diet (Ornish) and Pritikin suggest only 10% of your daily calories come from fat.
