Why Orlistat's Proven Mechanism Makes It Worth Buying
How Orlistat Blocks Fat Absorption
Orlistat works through a scientifically proven mechanism that blocks approximately one third of the fat you eat from being absorbed by your body. Unlike appetite suppressants that act on the brain, orlistat works locally in your digestive system by inhibiting lipase enzymes responsible for breaking down dietary fat. When these enzymes are blocked, the unabsorbed fat passes naturally through your body, reducing your calorie intake from dietary fat.
Three Treatment Options Available
Understanding how orlistat works helps you choose the right option. Generic orlistat 120mg offers the most cost-effective choice at £32.99 for 4 weeks (£29.69 with EDM10). Branded Xenical 120mg contains identical active ingredients at £42.99 for 4 weeks (£38.69 with EDM10). Alli 60mg provides a lower-strength option at £54.99 for 8 weeks (£49.49 with EDM10). All work through the same fat-blocking mechanism.
Why This Mechanism Supports Weight Management
The proven fat-blocking action means orlistat can support weight management when you combine it with a reduced-calorie, lower-fat diet. Because it blocks approximately one third of dietary fat, keeping meals low in fat minimises gastrointestinal side effects whilst maximising the weight management benefits. This targeted mechanism makes orlistat different from stimulant-based treatments.
