The following diagram depicts how prescription Xenical diet pills blocks fats from being absorbed into the bloodstream. Hence Xenical diet pills act as a "fat blocker" significantly reducing the caloric intake of calories from the consumption of fats in the diet.
*Xenical® works here, covalently bonding to the pancreatic lipases.
Xenical diet pills use a fat blocking mode of action that works non-systemically in the gastrointestinal tract. Dietary fats are large molecules that must be broken down by enzymes, called lipases, before the fats can be absorbed into the bloodstream. Xenical slimming pills interfere with these lipases by forming covalent bonds with them in the stomach and small intestine, this essentially inactivates the enzymes so they are no longer available to hydrolyze dietary fat into an absorbable state.
Thus, allowing for some 30 percent of dietary fats to pass through the gastrointestinal tract unchanged or in an a state that cannot be absorbed. This results in a reduction in some thirty percent of calories from fat consumed in the diet. Hence, Xenical is termed the first and only prescription "fat blocker." That enables you to lose weight fast.
