The Science Behind Orlistat - Why It Works
How Orlistat Blocks Fat Absorption
Orlistat works through a proven scientific mechanism that targets fat digestion in your gut. When you eat a meal containing fat, your body normally produces lipase enzymes to break down dietary fats so they can be absorbed into your bloodstream. Orlistat inhibits these lipase enzymes, preventing them from breaking down approximately one third of the fat you consume. This undigested fat cannot be absorbed by your body and passes through your digestive system naturally, reducing the calories absorbed from fatty foods.
Why This Mechanism Makes Orlistat Effective
Understanding how orlistat works explains why it's an effective weight management tool when used alongside a reduced-calorie, lower-fat diet. Because orlistat blocks approximately one third of dietary fat absorption, it helps reduce your overall calorie intake from meals containing fat. This creates a calorie deficit that can support weight loss when combined with healthy eating and increased physical activity. The mechanism is local to your digestive system - orlistat isn't absorbed into your bloodstream in significant amounts, making it different from appetite suppressants that act on your brain.
Orlistat 120mg vs Xenical - Same Mechanism, Different Prices
Both generic orlistat 120mg and branded Xenical 120mg contain exactly the same active ingredient and work through the identical fat-blocking mechanism. Generic orlistat 120mg costs £32.99 for 4 weeks (£29.69 with EDM10), while branded Xenical costs £42.99 for 4 weeks (£38.69 with EDM10). The fat-blocking effect is clinically equivalent - the main difference is cost. For longer treatment, orlistat 120mg 12-week supply costs £95.99 (£86.39 with EDM10) compared to Xenical's £128.99 (£116.09 with EDM10), saving you over £30.
