Alli - a diet pill for increased weight loss. Based on Orlistat

Alli is a non-prescription drug taken for weight loss. Alli's higher potency prescription counterpart is Xenical, also called Orlistat. Alli is a reduced strength type of Orlistat.

Surprisingly, the Mayo clinic has reported that Alli can be somewhat effective as a weight loss supplement. As advertised, Alli appears to decrease the absorbtion of fat by the intestines, leading to less fat intake from the same meal as if you did not take the Alli.

However, given that the average weight loss one can expect using Alli is only about 6 pound per year, and given the nasty sounding side effects (loose stool, oily discharge, and more) of this over the counter medication one should consider using this very carefully.
