How Orlistat Blocks Fat Absorption
Orlistat works through a scientifically proven mechanism that targets lipase enzymes in your digestive system. These enzymes normally break down dietary fat for absorption. Orlistat inhibits approximately one third of these lipases, meaning roughly one third of the fat you eat cannot be digested or absorbed into your body. This unabsorbed fat passes naturally through your system, reducing your caloric intake from dietary fat.
Why This Mechanism Proves Effectiveness
Unlike treatments that work on the brain, orlistat acts locally in your gut where fat absorption occurs. This targeted approach means you can see direct evidence the medication is working. The mechanism is not dependent on appetite changes or willpower - it physically prevents approximately one third of dietary fat absorption regardless. Generic orlistat 120mg costs from £16.89 (£15.20 with EDM10) for 2 weeks, while branded Xenical costs £21.50 (£19.35 with EDM10).
Clinical Evidence Supporting the Mechanism
MHRA regulation confirms orlistat's mechanism for adults with BMI 30+ or BMI 28+ with weight-related health conditions. The lipase inhibition occurs immediately after taking each capsule with fat-containing meals. One capsule three times daily with main meals ensures consistent fat-blocking action throughout the day. Studies demonstrate this mechanism can support weight management when combined with a reduced-calorie, lower-fat diet and increased physical activity.
Comparing Your Options
Understanding how orlistat works helps you choose between generic and branded versions. Both orlistat 120mg and Xenical 120mg contain identical active ingredients at the same dose, providing the same fat-blocking mechanism. Generic orlistat offers significant savings - 4 weeks costs £32.99 (£29.69 with EDM10) compared to Xenical at £42.99 (£38.69 with EDM10). Alli 60mg provides the same mechanism at half strength for £28.99 (£26.09 with EDM10) per 4 weeks.
