How Do Fat Absorption Inhibitors Work?
Fat-absorption inhibitors work by preventing your body from breaking down and absorbing fat eaten with your meals. This unabsorbed fat is eliminated in bowel movements. Do Prescription Weight Loss Drugs Really Work? In general, Xenical and Meridia are moderately effective, leading to an average weight loss of 5 to 22 pounds over a 1 year period, more than what would be expected with non-drug treatments. However, the response to these medications is based on each individual, and some people experience more weight loss than others. Likewise, there is no one correct dose for these medications. Your doctor will decide what works best for you based on his or her evaluation of your medical condition and your response to treatment.
