Xenical (Orlistat 120mg) is an FDA-approved weight loss medication designed to help obese and overweight individuals shed pounds by blocking the absorption of dietary fat. But does it really work?
If you're considering Xenical for weight loss, this guide will cover:
✅ How Xenical works
✅ Clinical evidence on its effectiveness
✅ Benefits and side effects
✅ Best diet and exercise plan to maximize results
How Does Xenical (Orlistat 120mg) Work?
Xenical belongs to a class of drugs called lipase inhibitors. It works by preventing about 30% of the fat you consume from being absorbed.
? Normal digestion: Your body breaks down fats with an enzyme called lipase so they can be absorbed.
? With Xenical: The drug blocks lipase, causing undigested fat to pass out of the body instead of being stored.
? Key point: Xenical only blocks fat calories—it does NOT prevent absorption of protein, carbohydrates, or sugars.
Does Xenical Really Help with Weight Loss?
Yes! Clinical studies confirm that Xenical helps people lose weight more effectively than diet and exercise alone.
? Research Findings:
? In a 1-year clinical trial, people taking Xenical lost an average of 10% of their body weight compared to 6% in the placebo group.
? In a 4-year study, Xenical users maintained 5.8 kg (12.7 lbs) more weight loss than those not using it.
? Xenical works best when combined with a low-fat diet and regular exercise.
