Why Understanding the Mechanism Matters for Your Purchase
How Orlistat's Fat-Blocking Mechanism Works
Orlistat works through a scientifically-proven mechanism that targets lipase enzymes in your digestive system. These enzymes are responsible for breaking down dietary fat so it can be absorbed into your body. When you take orlistat 120mg with meals, it inhibits approximately one third of these lipase enzymes, meaning roughly one third of the fat you eat cannot be digested or absorbed. This unabsorbed fat passes naturally through your digestive system and is excreted, reducing the total calories your body absorbs from dietary fat.
Why This Mechanism Proves Orlistat Works
Unlike appetite suppressants that work on brain chemistry, orlistat's mechanism is direct and measurable. The fat-blocking action happens locally in your gut, which is why patients often notice oily stools when eating high-fat meals - this is actually proof the medication is working. Generic orlistat 120mg (from £29.69 for 4 weeks with EDM10) delivers exactly the same enzyme-blocking mechanism as branded Xenical 120mg, but at a significantly lower cost. Both formulations block approximately one third of dietary fat absorption through identical active ingredients.
Choosing Between Generic Orlistat and Xenical
Understanding that both products work through the same mechanism helps inform your purchasing decision. Generic orlistat 120mg costs £32.99 for 84 capsules (£29.69 with EDM10), while branded Xenical costs £42.99 for the same quantity (£38.69 with EDM10). The lipase-inhibiting mechanism is identical - you're paying approximately £9 less per month for the same fat-blocking action with generic orlistat. Some patients prefer the branded option, but clinically, both deliver the same approximately one-third fat absorption reduction.
Maximising the Fat-Blocking Effect
Knowing how orlistat works helps you use it effectively. The mechanism works best when dietary fat is spread evenly across three main meals, with no more than 15g fat per meal. Higher fat meals don't increase the fat-blocking effect - orlistat still blocks approximately one third - but they significantly increase gastrointestinal side effects as more unabsorbed fat passes through your system. This is why combining orlistat with a reduced-calorie, lower-fat diet isn't just recommended - it's essential for comfortable, effective treatment.
