Alli formally Xenical 

Ingredients: Orlistat 

Review: Alli contains Orlistat which stops fats from being absorbed by the body therefore reducing the calorie intake overall.

Alli works by the release of an enzyme in the users pancreas that helps to break down the fats in the intestine.

In layman terms when a fatty food is eaten, the body does not absorb it and it will be expelled through the bowel. The product does work but it can cause unpleasant side effects and incontinence.

Alli may cause weight loss but it may not be a lot. Although the product works the weight loss will counteract the benefit of weight loss with the many common side effects of incontinence and oily discharge.

For what the product is it can be quite expensive. Some testimonials have shown that Alli has worked but there are too many unpleasant side effects and incontinence so many of them are not positive.

There is no money back guarantee so if you try the product and you are very dissatisfied with it, there is no chance to get your money back. It varies in price but overall it is very expensive for what it does. 

Positives: widely available, reduces the absorption of lipids 

Negatives: expensive, unpleasant side effects, no money back guarantee, contains no effective appetite suppressants
