Why Understanding the Mechanism Matters Before You Buy
How Orlistat's Fat-Blocking Mechanism Works
Orlistat works by inhibiting pancreatic and gastric lipases - digestive enzymes responsible for breaking down dietary fats in your intestine. When these enzymes are blocked, approximately one third of the fat you eat cannot be digested or absorbed. This unabsorbed fat passes naturally through your digestive system and is eliminated from your body.
Unlike appetite suppressants that work in the brain, orlistat acts locally in your gut. This targeted mechanism means minimal absorption into your bloodstream whilst delivering measurable fat-blocking effects. The science is straightforward: less fat absorbed equals fewer calories consumed from dietary fat.
Orlistat vs Alli: Same Mechanism, Different Doses
Both orlistat 120mg and Alli 60mg use identical fat-blocking mechanisms. The key difference lies in potency - prescription orlistat 120mg blocks a greater proportion of dietary fat compared to Alli's 60mg dose. Generic orlistat 120mg costs £32.99 for 4 weeks (£29.69 with EDM10), whilst Alli 60mg costs £28.99 for 4 weeks (£26.09 with EDM10).
Xenical 120mg contains the same active ingredient as generic orlistat at the same dose - the clinical effect is identical. The branded option costs £42.99 for 4 weeks (£38.69 with EDM10), making generic orlistat the most cost-effective choice for the same fat-blocking mechanism.
Why the Mechanism Proves It Works
Orlistat's mechanism is measurable and visible. When taking orlistat with meals containing fat, you may notice oily stools or fatty discharge - direct evidence that dietary fat is being blocked rather than absorbed. These gastrointestinal effects, whilst initially inconvenient, demonstrate the medication is actively preventing fat absorption.
The mechanism works best when combined with a reduced-calorie, lower-fat diet. Keeping meals to approximately 15g fat each minimises side effects whilst maximising weight management benefits. High-fat meals increase gastrointestinal effects significantly.
