The Science Behind Orlistat - Why It Works
How Orlistat Blocks Fat Absorption
Xenical hard capsules contain orlistat 120mg, a lipase inhibitor that works directly in your digestive system. When you eat fat-containing foods, your body produces lipase enzymes to break down dietary fat for absorption. Orlistat blocks these enzymes, preventing approximately one third of the fat you eat from being digested and absorbed. This unabsorbed fat passes naturally through your body, reducing your total calorie intake from fatty foods.
Why The Mechanism Proves Effectiveness
Unlike stimulants that act on your brain, orlistat's mechanism is straightforward and measurable. By blocking approximately one third of dietary fat absorption, you reduce calorie intake without affecting protein, carbohydrate, or alcohol calories. This proven mechanism works whether you choose generic orlistat 120mg (from £29.69 for 4 weeks with EDM10) or branded Xenical 120mg (from £38.69 for 4 weeks with EDM10). Both contain identical active ingredient at the same dose.
Local Action, Systemic Benefits
Orlistat acts locally in your gut rather than being absorbed into your bloodstream in significant amounts. This targeted approach means the fat-blocking effect occurs where you need it - in your digestive system. The blocked fat cannot contribute to weight gain because it never enters your body's energy storage systems. This mechanism supports weight management when combined with a reduced-calorie, lower-fat diet.
Comparing Your Options
Understanding how orlistat works helps you choose between available options. Generic orlistat 120mg and Xenical 120mg work identically - both block approximately one third of dietary fat using the same mechanism. The key difference is cost, with generic orlistat offering significant savings. For those preferring lower-strength options, Alli 60mg uses the same mechanism at half the dose. All require the same dietary approach for optimal results.
Maximising The Fat-Blocking Effect
Now you understand the mechanism, you can optimise results by keeping meals low in fat (approximately 15g fat per meal). High-fat meals increase gastrointestinal side effects as more unabsorbed fat passes through your system. The fat-blocking mechanism works best alongside dietary changes - orlistat enhances your efforts rather than replacing them. Following clinical assessment, our UK-licensed prescribers can determine if this mechanism suits your weight management goals.
