How Orlistat's Fat-Blocking Mechanism Works
Orlistat works through a scientifically proven mechanism that targets lipase enzymes in your digestive system. These enzymes normally break down dietary fat so your body can absorb it. When you take orlistat, it inhibits these lipases, preventing approximately one third of the fat you eat from being digested and absorbed. This unabsorbed fat then passes naturally through your body.
Unlike appetite suppressants that affect your brain, orlistat acts locally in your gut and isn't significantly absorbed into your bloodstream. This targeted approach means you're getting a clinically proven fat-blocking effect without systemic stimulant effects.
Why Understanding the Mechanism Matters for Your Purchase Decision
Knowing how orlistat blocks fat absorption helps you choose the right strength. Alli 60mg provides this proven mechanism at a lower dose, available from £28.99 for 4 weeks (£26.09 with EDM10). For maximum fat-blocking effect, prescription orlistat 120mg delivers the full clinical dose from just £16.89 for 2 weeks (£15.20 with code EDM10).
The mechanism also explains why orlistat works best alongside a reduced-calorie, lower-fat diet. When you eat high-fat meals, more unabsorbed fat passes through your system, which can cause gastrointestinal side effects. Understanding this helps you maximise results while minimising discomfort.
Orlistat vs Xenical: Same Mechanism, Different Prices
Both generic orlistat 120mg and branded Xenical 120mg use identical fat-blocking mechanisms - they contain the same active ingredient at the same dose. The clinical effect is identical, but generic orlistat costs significantly less. A 4-week supply of orlistat costs £32.99 (£29.69 with EDM10) compared to Xenical at £42.99 (£38.69 with EDM10).
This price difference exists because you're paying for branding with Xenical, not superior fat-blocking capability. Both products inhibit approximately one third of dietary fat absorption through the same proven mechanism.
