Why Understanding Orlistat's Mechanism Matters for Your Purchase

How Orlistat Blocks Fat Absorption - The Science That Drives Results

Orlistat works through a precise mechanism that makes weight gain impossible when used correctly. The medication inhibits lipase enzymes in your digestive system, preventing approximately one third of dietary fat from being absorbed into your bloodstream. This unabsorbed fat passes naturally through your body, reducing your calorie intake from dietary fat. Generic orlistat 120mg costs £32.99 for 4 weeks (£29.69 with EDM10), delivering this proven fat-blocking mechanism at exceptional value.

Orlistat vs Xenical - Identical Mechanisms, Different Prices

Both generic orlistat and branded Xenical contain identical 120mg doses of the same active ingredient. The mechanism remains constant - blocking approximately one third of dietary fat absorption regardless of which version you choose. Xenical 120mg costs £42.99 for 4 weeks (£38.69 with EDM10), while generic orlistat delivers the same clinical effect for £32.99 (£29.69 with EDM10). Understanding this identical mechanism helps you make an informed purchasing decision based on value rather than marketing.

Why This Mechanism Prevents Weight Gain

The lipase inhibition mechanism makes orlistat-induced weight gain scientifically impossible. By reducing fat absorption by approximately one third, orlistat creates a calorie deficit when combined with a reduced-calorie, lower-fat diet. This mechanism works locally in your gut without affecting your brain or metabolism. For longer treatment periods, orlistat 168 capsules (8 weeks) costs £63.99 (£57.59 with EDM10), while 252 capsules (12 weeks) costs £95.99 (£86.39 with EDM10).

Alli 60mg - Half-Strength Mechanism for Gradual Results

Alli contains 60mg orlistat - exactly half the prescription dose - working through the same fat-blocking mechanism but with reduced intensity. This lower-strength option blocks a smaller proportion of dietary fat, making it suitable for those preferring gradual results. Alli 84 capsules (8 weeks) costs £54.99 (£49.49 with EDM10), offering an accessible entry point to orlistat's proven mechanism.
