Lipozene is a weight-loss supplement containing the active ingredient glucomannan, also called konjac fiber. This vegetable fiber is derived from the root of the plant Amorphophallus konjac, which is native to Asia. Early research indicates glucomannan is a promising fiber supplement and might be effective for weight loss, according to eMedTV. The website cautions that Lipozene itself has not been studied, and that the advertised claims do not accurately reflect existing research results for its active ingredient. The Lipozene official website recommends consulting your health-care provider before beginning any weight-loss program and before taking this herbal supplement.
Function
The active ingredient in Lipozene, glucomannan, is a type of soluble dietary fiber. It passes through the digestive tract without breaking down and slows emptying of the stomach contents into the intestines, explains eMedTV. This helps people feel full longer, and thus they might eat less. Like other types of dietary fiber, Lipozene can also help keep blood sugar levels even, according to eMedTV.
Effectiveness
A study published in the Jan. 1, 1984, issue of the "International Journal of Obesity" investigated the effects of glucomannan fiber on 20 obese participants who were told not to change their eating or exercise habits. The participants took two 500-mg capsules of glucomannan fiber with 8 oz. water before each of three meals per day. Average weight loss over eight weeks was 5.5 lbs., and these individuals also experienced significant decreases in low-density lipoprotein cholesterol, the so-called bad cholesterol.
Additional Benefit
Because its active ingredient is soluble dietary fiber, Lipozene also is useful for relieving occasional constipation and maintaining regular bowel movements, as noted by the Physicians' Desktop Reference. Soluble dietary fiber helps form large soft stools that are easy to pass. This is gentler on the digestive tract than stimulant laxatives, which cause intestinal contractions to produce bowel movements.
Usage
Lipozene capsules contain 1,500 mg of glucomannan each. The official website recommends taking one or two capsules with 8 oz. of water 30 minutes before each meal. Lipozene has a money-back guarantee that you will lose weight and body fat, but the website notes that the amount of weight loss varies depending on each individual.
Side Effects
The most common side effects associated with Lipozene are gastrointestinal, explains the Physicians' Desktop Reference. You might experience gas, bloating, upset stomach, nausea, vomiting or diarrhea. Rarely, some people experience an allergic reaction to glucomannan, with signs of hives, a rash, swelling, breathing difficulty, or tightness in the chest or throat.
