Lipozene is advertised as a pill that can reduce body fat and lead to weight loss. Yet the evidence to back up the claims of this magic pill is a bit tenuous. For example, the main ingredient in Lipozene, glucomannan, has been studied on several occasions. The substance has been shown to ultimately lead to weight loss, but in studies of glucomannan with successful results, dieters have also exercised and dieted. Glucomannan is a natural fiber that's derived from the konjac root. Glucomannan is effective at helping people lose weight because it's very water soluble. When combined with water, soluble fibers form a paste in a person's digestive tract; the paste causes the digestive system to slow down. Glucomannan is more potent than the soluble fibers found in foods. It acts as a sponge that grows by about 17 percent from its original size.
The theory behind Lipozene is that once glucomannan has puffed out inside your stomach, you won't be as hungry. As a result, it becomes much easier to decrease your caloric intake, which leads to weight loss. Lipozene, which you can purchase without a prescription, wasn't specifically dealt with in the glucomannan studies. Although the Lipozene marketing campaign claims that all you need to lose weight is to pop a pill, there's no solid scientific evidence to back this up. Furthermore, the company that makes Lipozene has had past run-ins with the Federal Trade Commission over false claims it made about other weight-loss products that it manufactured.
According to the American Dietetic Association, the professional association for registered dietitians, there are no foods or pills that magically burn fat, as claims on television often say. In fact, the ADA says that where fad diets and pills are concerned, "If it sounds too good to be true, it probably is" [source: EatingRight.org]. Instead, gradual weight loss that's accomplished through a combination of eating healthy foods in smaller portions and exercising regularly leads to weight loss that lasts. This type of weight loss may not occur as rapidly as the claims made by makers of diet pills and fads, but it's successful loss that tends to last and the type of lifestyle changes that make people healthier.
