One of the most popular weight loss products on the market right is a product called Alli. This pill works as a fat blocker that prevents 25% of your fat and calorie intake from being absorbed into your body.  This allows you to continue eating the foods you like while you take alli diet pills.  However, according to recent user reviews, there have been several reported side effects from both men and women.  Many people seem to be complaining about explosive diarrhea and leakage at the most undesirable times.  This can be very embarrassing and should be heavily considered by all people before trying Alli weight loss pills.  Overall, Alli pills probably do work, but use them at your own risk.
