obesity
"Just want to update since previous review:

To understand how this product works you have to know what it does. It blocks a certain amount of the fat you eat from being aborbed into your body and thus reduces your calorie/fat intake. It's not a miracle drug, if you eat a very high fat diet yes it may help a bit but it won't do ALL the work.

Also, if you eat little/no fat anyway it can't help as it won't do anything for you. It can't block fat that isn't there. 

If like me you're on a long term diet it can really boost your success. I have gone from a bmi of 47 to 39 in 6 months. Still some way to go but Alli is helping a great deal and keeps me motivated with consistent weekly weight losses."
