alli is a diet pill that you take with each meal, 3 times a day. The pill causes your body to block up to 1/3 of your normal fat processing. So, it reduces the number of calories and fat you get from eating.

alli contains Orlistat with is the same active ingredient that is found in Xenical. alli is a new formulation, made by GlaxoSmithKline, which is produced at a lower dose and has been approved by the FDA for over-the-counter sales. GlaxoSmithKline has put a lot of money into a major marketing campaign timed with Alii's debut, mid-June 2007. alli will be available in stores June 15, 2007. There are also books about alli that have already been published. For example, "The alli Diet Plan" by Caroline Apovian M.D.

alli (Orlistat) is derived from lipstatin. Lipstatin is a strong but natural drug which binds and blocks lipase (an enzyme made by your pancreas). The result is that you body is unable to process all of the fat that you eat. The fat passes through you when you go the bathroom instead of being added to your body.

Xenical was developed as an anti-obesity drug. But, now we have alli which is available over the counter, so now anyone can take it (you don't have to be obese or have a serious weight problem anymore). The price of alli is expected to be relatively affordable, as well.

Changing your diet and exercise is no required to lose weight while taking alli, though it very likely would help. You can do all three. But, the beauty of alli is that you don't have to change your lifestyle to lose weight. Just take an alli with each meal, three times a day, and you should see a difference.

Some people have side-effects from alli, namely lose stools, especially if you have a very fatty meal. Also, because the fats pass through your body, there's some chance that you'll lose some important nutrients. Taking a multi-vitamin along with alli should help compensate for that unlikely possibility.
