Obesity
"I have used Alli and was very happy.  It absolutely will help you lose weight. If you are planning on not adjusting your diet, it is not for you.  Since it inhibits fat from being absorbed, fat goes right through you and could definitely be embarrassing (if you know what I mean).  If you lower the fat in your diet, it will do wonders and the disgusting side effects will be minimal to non-existent."
