Xenical 120mg costs £42.99 for 4 weeks (£38.69 with EDM10), whilst generic orlistat 120mg offers identical results from £32.99 (£29.69 with EDM10). Both require a prescription following online clinical assessment.

The Science Behind Fat Blocking - Ready to Order?

How Orlistat Blocks Fat Absorption

Orlistat works through a targeted mechanism in your digestive system. It inhibits lipase enzymes responsible for breaking down dietary fat, preventing approximately one third of the fat you eat from being absorbed into your body. This unabsorbed fat passes naturally through your system and is excreted. Unlike appetite suppressants that affect the brain, orlistat acts locally in the gut and is not significantly absorbed into your bloodstream.

Why "One Third" Matters for Weight Management

Blocking approximately one third of dietary fat absorption can significantly reduce calorie intake when combined with a reduced-calorie, lower-fat diet. If you consume 60g fat daily, orlistat may prevent around 20g from being absorbed - that's 180 fewer calories per day. Generic orlistat 120mg delivers this proven mechanism from £29.69 monthly with EDM10, whilst Xenical 120mg offers identical fat-blocking action at £38.69 monthly with EDM10.

Xenical vs Generic Orlistat - Same Mechanism, Different Prices

Both Xenical 120mg and generic orlistat 120mg contain identical active ingredients and block approximately one third of dietary fat through the same proven mechanism. The clinical effect is identical - the key difference is cost. Generic orlistat offers the same fat-blocking science as branded Xenical but costs around £9 less per month. Choose 4-week supplies from £29.69 (generic) or £38.69 (Xenical) with code EDM10.

When Fat Blocking Works Best

Orlistat's mechanism works most effectively when meals contain moderate fat levels - approximately 15g fat per meal. Higher-fat meals increase both fat blocking and potential gastrointestinal effects, as more unabsorbed fat passes through your system. This is why following a lower-fat, reduced-calorie diet maximises results whilst minimising side effects. The mechanism proves orlistat is working when used correctly.
