Fat blocking
Fat contains the most energy (calories) within your diet and if not burned (used) it is stored by your body. With modern day jobs where majority of people are sitting whole day what lacks physical activity fat blocking seems pretty smart solution to this problem.
Fat blocking within your digestive system
We strongly believe that for now orlistat is the only effective and safe fat blocker you can get. Absorption of fat is blocked within your digestive system which is great news because other weight loss products like certain appetite suppressants and almost all fat burners influence your heart rate and even brain which can cause serious problems to your health in longer term.

Orlistat blocks the activity of lipase, the enzyme that breaks down fat, and fats from the diet are not transformed into absorbable free fatty acids and are passed out of the body naturally in form of feces.
Fat blockers
Only fat blockers which use orlistat are Xenical and Alli. Xenical is prescription drug for really obese patients but Alli is its weaker version and is non-prescription and is sold over-the-counter in pharmacies on high street and online.
