Why Orlistat's Fat-Blocking Mechanism Makes It Effective

How Orlistat Blocks Fat: The Science Behind Weight Loss

Orlistat works through a targeted mechanism that blocks approximately one third of the fat you eat from being absorbed. It inhibits lipase enzymes in your digestive system - these are the enzymes responsible for breaking down dietary fat. When these enzymes are blocked, the unabsorbed fat passes naturally through your body rather than being stored. This proven mechanism means you consume fewer calories from fat, supporting weight loss when combined with a reduced-calorie, lower-fat diet.

Orlistat vs Xenical: Identical Fat-Blocking Action

Generic orlistat 120mg and branded Xenical 120mg contain exactly the same active ingredient at the same dose. Both work through the identical fat-blocking mechanism, inhibiting approximately one third of dietary fat absorption. The key difference is cost - generic orlistat at £32.99 for 4 weeks (£29.69 with EDM10) offers significant savings versus Xenical at £42.99 (£38.69 with EDM10). You get the same proven fat-blocking effect while saving approximately £9 per month.

Why Fat Blocking Works Better Than Appetite Suppressants

Unlike appetite suppressants that act on the brain, orlistat works locally in your gut and isn't absorbed into your bloodstream in significant amounts. This targeted mechanism means it directly addresses dietary fat - often the highest calorie component of meals. By blocking approximately one third of fat absorption, orlistat helps reduce your overall calorie intake from one of the most calorie-dense food components. This makes it particularly effective for people who struggle with high-fat foods.

Maximising Orlistat's Fat-Blocking Effect

Orlistat's mechanism works best when you distribute fat intake evenly across three main meals, keeping each meal to approximately 15g fat. Higher fat meals don't increase the blocking effect beyond one third, but they significantly increase side effects. The unabsorbed fat needs to exit your body, so keeping fat intake moderate ensures the mechanism works comfortably. This is why orlistat works most effectively alongside a structured, lower-fat diet plan.
