Xenical, or Orlistat, in its generic form, works by reducing
the amount of fat absorbed from your diet; it is not an appetite suppressant.
When fat enters the body, it is broken down by enzymes called lipases, so that
the body can digest it. Xenical (Orlistat) attaches itself to the enzymes in
the body so that they cannot break down the fat, which stops about one third of
the fat from your meal from being absorbed, so that your body passes the fat
rather than storing it.
The undigested fat is then passed through your digestive
system with no unwanted effects on your heart rate or sleeping pattern.
Orlistat has been tested in hundreds of clinical studies and has proven to be
very safe, yet very efficient.
Xenical (Orlistat) should only be used by those who are
medically obese; those with a BMI of 30 or more or a BMI of 28 or more in those with other risk factors such as diabetes or hypertension.
