Why Understanding How Orlistat Works Matters
The Science Behind Xenical Capsules
Xenical capsules contain orlistat 120mg, a lipase inhibitor that works through a proven mechanism in your digestive system. Unlike appetite suppressants that act on the brain, orlistat works locally in your gut by blocking specific enzymes called lipases. These enzymes are responsible for breaking down dietary fat into smaller molecules that can be absorbed into your bloodstream. When orlistat inhibits these lipases, approximately one third of the fat you eat cannot be digested or absorbed, instead passing naturally through your body.
How Fat Blocking Supports Weight Management
By preventing approximately one third of dietary fat absorption, orlistat effectively reduces the caloric impact of fat-containing meals. Since fat contains 9 calories per gram compared to 4 calories per gram for protein or carbohydrates, blocking fat absorption can significantly reduce overall calorie intake. This mechanism works best when combined with a reduced-calorie, lower-fat diet - keeping meals to approximately 15g fat each minimises side effects whilst maximising effectiveness. Generic orlistat 120mg costs just £29.69 for 4 weeks with code EDM10, offering identical results to branded Xenical at £38.69.
Why Choose Orlistat Over Other Approaches
Understanding orlistat's mechanism explains why it's prescribed by healthcare professionals worldwide. Unlike stimulant-based treatments, orlistat doesn't affect your central nervous system or heart rate. It simply prevents some dietary fat absorption whilst you continue eating normally within a structured weight management programme. The unabsorbed fat provides visible evidence the medication is working, giving you confidence in the treatment. Both generic orlistat and branded Xenical contain identical 120mg doses with the same clinical effect - the choice between them often comes down to personal preference and budget.

What to Expect When Treatment Begins
Most patients notice orlistat's effects within 24-48 hours of starting treatment. The mechanism means you may experience oily stools or urgency, particularly after higher-fat meals - this confirms the medication is blocking fat absorption as intended. These effects reduce significantly when you adapt to eating lower-fat meals (around 15g fat per meal). Take one capsule with each main meal containing fat, up to three times daily. If you miss a meal or eat a fat-free meal, skip that dose. A daily multivitamin taken at bedtime helps maintain fat-soluble vitamin levels.
