Alli and Diet
Alli is the first and only FDA-approved over-the-counter weight loss supplement. Alli is the brand name version of orlistat and is a less-potent version of the prescription weight loss drug Xenical. The manufacturers of Alli strongly recommend that patients follow a healthy diet and exercise routine while taking Alli and use Alli as a supplement to patients' weight loss efforts. While taking Alli, patients are advised to follow the Alli weight loss program, which consists of a low-fat, reduced-calorie diet, increased amounts of daily exercise and attitude changes about food and exercise. Alli is not recommended for those who are pregnant or under 18 years of age.
Alli Blocks Fat
Unlike other weight loss drugs that act as a stimulant, Alli blocks fat within the digestive system. According to Alli manufacturers, the active ingredient in Alli attaches to the body's natural enzymes in the digestive process that naturally break down fat molecules, inhibiting the absorption of fat. With Alli, about a quarter of all fat consumed cannot be digested and passes through the body without absorption. Because fat contains more calories than protein or carbohydrates, the blocking of fat absorption has helped patients lose about 50 percent more weight than with diet and exercise alone, according to the manufacturer's clinical trials.
Side Effects of Alli
Many patients who take Alli warn consumers about the product's side effects. As the fat passes through the body undigested, it affects patients' bowel movements and gastrointestinal tract, leading to flatulence with oily spotting, quick onset of bowel movements, fatty stools and oily stools. To ease these side effects, Alli manufacturers recommend patients consume no more than 15 grams of fat per meal.
