Why Orlistat's Fat-Blocking Action Makes It Effective
How Orlistat's Mechanism Delivers Results
Orlistat's effectiveness for weight loss lies in its specific mechanism of action. Unlike appetite suppressants that work on the brain, orlistat works locally in your digestive system by inhibiting lipase enzymes responsible for breaking down dietary fat. This fat-blocking action means approximately one third of the fat you eat cannot be digested or absorbed - it passes naturally through your body instead. This mechanism provides a direct reduction in calories from dietary fat, supporting weight management when combined with a reduced-calorie, lower-fat diet.
Why "Approximately One Third" Fat Blocking Matters
The fact that orlistat blocks approximately one third of dietary fat is clinically significant for weight loss. If you consume 60g of fat daily, orlistat may prevent around 20g from being absorbed - that's approximately 180 fewer calories per day. Over time, this calorie reduction can contribute meaningfully to weight loss alongside dietary changes. Generic orlistat 120mg provides this same fat-blocking mechanism from just £29.69 for a 4-week supply (with EDM10), making it a cost-effective option compared to branded Xenical at £38.69.
Evidence That Orlistat's Mechanism Works
Orlistat's fat-blocking action isn't theoretical - you may actually see the evidence that it's working. The unabsorbed fat passes through your digestive system, which can cause oily stools or spotting. While these gastrointestinal effects can be managed by keeping meals low in fat (around 15g per meal), they demonstrate that the medication is actively blocking fat absorption. This visible proof of the mechanism working gives many patients confidence that orlistat is genuinely reducing their calorie intake from dietary fat.
Choosing Between Orlistat, Xenical, and Alli
All three products work through the same fat-blocking mechanism, but at different strengths. Generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients and provide the same approximately one-third fat-blocking action. The key difference is price - orlistat 120mg costs £57.59 for an 8-week supply with EDM10, while Xenical costs £78.29. Alli 60mg provides the same mechanism at half strength, starting from £26.09 for 4 weeks. Understanding how each works helps you choose the right option for your weight management goals and budget.
