The Science Behind Orlistat: Why It Works
How Orlistat Blocks Fat: The Mechanism Explained
Orlistat works through a scientifically proven mechanism that targets fat absorption directly in your digestive system. Unlike appetite suppressants that act on the brain, orlistat inhibits lipase enzymes in your gut - the enzymes responsible for breaking down dietary fat. When these enzymes are blocked, approximately one third of the fat you eat cannot be digested or absorbed into your body. This unabsorbed fat passes naturally through your digestive system, reducing the calories absorbed from fatty foods.
Why Choose Generic Orlistat Over Xenical?
Both generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients and work through exactly the same fat-blocking mechanism. The key difference is cost - generic orlistat delivers the same clinical effect at a significantly lower price. At EverydayMeds, orlistat 120mg costs from £32.99 for 84 capsules (4 weeks), compared to £42.99 for equivalent Xenical - that's £10 monthly savings. With code EDM10, you save even more: orlistat becomes £29.69 versus Xenical at £38.69.
Proven Fat Blocking in Action
The mechanism is straightforward but effective. When you take one orlistat 120mg capsule with each main meal containing fat, the medication works locally in your gut to inhibit pancreatic lipase enzymes by approximately 30%. This prevents roughly one third of dietary fat from being broken down into absorbable components. The blocked fat is eliminated naturally, reducing calorie intake from fatty foods while you maintain a reduced-calorie, lower-fat diet.

Why the Mechanism Matters for Your Weight Goals
The lipase inhibition mechanism provides predictable, measurable results when combined with dietary changes. Because orlistat blocks approximately one third of fat absorption consistently, you can expect reliable support for your weight management efforts. The medication works best when fat intake is distributed evenly across three main meals with no more than 15g fat per meal - this optimises the fat-blocking effect while minimising gastrointestinal side effects that occur when unabsorbed fat is eliminated.
