Why Orlistat's Mechanism Proves It Works
How Orlistat Blocks Fat Absorption
Orlistat works by inhibiting lipase enzymes in your digestive system that break down dietary fats. When these enzymes are blocked, approximately one third of the fat you eat cannot be digested or absorbed into your body. This unabsorbed fat passes naturally through your digestive system, reducing the calories absorbed from fatty foods. The mechanism is completely different from appetite suppressants - orlistat acts locally in the gut rather than affecting your brain.
Orlistat and Metformin Combined Approach
Many patients using metformin for type 2 diabetes find orlistat complements their weight management goals. While metformin helps regulate blood sugar and may support modest weight loss, orlistat specifically targets dietary fat absorption. Generic orlistat 120mg costs just £32.99 for 84 capsules (4 weeks), or £29.69 with code EDM10. This dual approach - metformin managing glucose and orlistat reducing fat absorption - can support comprehensive weight management when prescribed appropriately.
Why "Approximately One Third" Matters
Orlistat blocks approximately one third of dietary fat - not 100%. This precise mechanism means roughly 67% of dietary fat is still absorbed normally, while 33% passes through undigested. This targeted action explains why maintaining a lower-fat diet (around 15g fat per meal) minimises side effects while maximising weight loss support. The mechanism is dose-dependent - Xenical 120mg and generic orlistat 120mg provide identical fat-blocking effects, while Alli 60mg offers half the potency.
Clinical Evidence Behind the Mechanism
The lipase inhibition mechanism has been extensively studied, showing orlistat can support 5-10% body weight reduction when combined with dietary changes. Xenical 120mg (branded orlistat) costs £42.99 for 4 weeks, while generic orlistat provides identical clinical effects for £32.99. Both require prescription following clinical assessment by our UK-licensed prescribers. The mechanism works best alongside a reduced-calorie, lower-fat diet and regular physical activity.
