Why Orlistat's Fat-Blocking Mechanism Makes It Work
How Orlistat Blocks Fat Absorption - The Science
Orlistat works by inhibiting lipase enzymes in your digestive system that normally break 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 calorie intake from dietary sources. The mechanism proves orlistat works - it physically prevents fat absorption rather than acting on your brain or metabolism.
Generic Orlistat vs Xenical - Same Fat-Blocking Power
Both generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients that block the same amount of dietary fat. Generic orlistat offers significant savings: 4 weeks costs £32.99 (£29.69 with EDM10) versus Xenical at £42.99 (£38.69 with EDM10). The fat-blocking mechanism is identical - the difference is price. Alli 60mg provides half the dose for those preferring lower-strength treatment at £28.99 for 4 weeks (£26.09 with EDM10).
Why the Fat-Blocking Mechanism Proves It Works
Unlike appetite suppressants that affect brain chemistry, orlistat's mechanism is straightforward and measurable. By blocking approximately one third of dietary fat absorption, it directly reduces calorie intake from fat sources. This mechanical action explains why orlistat may help support weight management when used alongside a reduced-calorie, lower-fat diet. The unabsorbed fat provides visible proof the medication is working, though this may cause gastrointestinal side effects initially.
