Alli is an over-the-counter weight loss pill that contains the active ingredient orlistat. Orlistat works by blocking the absorption of about 25% of the fat in the foods you eat, which is then passed through bowel movements. Alli is meant to be used as part of a weight-loss plan, along with a low-calorie, low-fat diet and regular physical activity. Clinical studies have shown that for every 2 pounds you lose through diet and exercise alone, Alli can help you lose 1 pound more. Alli is the only FDA-approved weight loss aid available without a prescription.
Positive aspects of Alli include that it has been shown to help people lose more weight than dieting alone, and that it is supported by a comprehensive weight loss program to help promote a healthy dietary lifestyle and gradual weight loss.
Negative aspects of Alli include that the weight loss will likely be modest, and that it may cause some side effects such as oily or fatty stools, abdominal pain, and gas with discharge. Additionally, Alli may not be suitable for everyone, and it is important to talk to a healthcare provider before starting to use it.
Ingredients of Alli include orlistat as the active ingredient, and inactive ingredients such as FD&C Blue No. 2, edible ink, gelatin, iron oxide, microcrystalline cellulose, povidone, sodium lauryl sulfate, sodium starch glycolate, talc, and titanium dioxide.
