Alli is the first diet pill approved by the Food and Drug Administration that's available without a prescription. You can get it over-the-counter, but its active ingredient, Orlistat, has long been used in prescription diet pills. Orlistat has been widely studied and is considered to be both safe and effective, although there are far fewer studies on Alli itself. Nevertheless, reputable medical sources like the Mayo Clinic report that Alli can be an effective tool for long-term weight loss. Note that you will not lose weight quickly with Alli but will be more likely to keep the weight off than users of other diet pills may be.

If you stick to the Alli diet and exercise plan, it you may succeed in keeping this weight off. But remember, Alli sometimes causes uncomfortable side effects when you first start using it, and it requires a long-term lifestyle commitment that not everyone can maintain.
