Obesity, in general, is a chronic condition defined by an excess amount of body fat. A certain amount of body fat is necessary for storing energy, heat insulation, shock absorption, and other functions. The normal amount of body fat (expressed as percentage of body fat) is between 25-30% in women and 18-23% in men. Women with over 30% body fat and men with over 25% body fat are considered obese.

Obesity has reached epidemic proportions in the United States. One in three Americans are obese. Obesity is also increasing rapidly throughout the world.

Most fat burners operate on the principle of thermogenisis (the breakdown of bodyfat). A good fat burner will do three things well. First, your stored fats will be burned for energy. Second, your fat cells must be broken down and mobilized. And third, we need to "rev up" the metabolic rate to "burn" stored fat and inhibit fat cells from enlarging.

Fat burners are generally some combination of herb-derived stimulants, essential fatty acids, chromium picolinate, pyruvate, and/or hydroxycitric acid.

Herb-derived stimulants include caffeine and ephedrine as well as the herbs guarana and ma huang. Two or three of these stimulants are usually 'stacked' together in one weight loss product, often along with aspirin or willow bark . They are supposed to increase energy while stimulating fat burning. Most experts agree they do work when combined with exercise.
