Why Orlistat's Mechanism Makes It Effective
How Orlistat Works: The Fat-Blocking Mechanism
Orlistat's effectiveness comes from its unique 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 proven mechanism blocks approximately one third of the fat you eat from being absorbed into your body. The unabsorbed fat passes naturally through your digestive system, reducing the calories absorbed from dietary fat.
Why This Mechanism Proves Orlistat Works
The lipase-blocking mechanism is what makes orlistat clinically effective for weight management. When you take orlistat 120mg with meals containing fat, it immediately begins blocking fat absorption. This isn't a temporary effect - the mechanism works consistently with every dose. Both generic orlistat (from £29.69 for 4 weeks with EDM10) and branded Xenical (from £38.69 for 4 weeks with EDM10) use this identical proven mechanism.
Orlistat vs Other Weight Loss Approaches
Orlistat's mechanism targets dietary fat specifically, making it different from other weight management approaches. The fat-blocking action is measurable and predictable - approximately one third of dietary fat is prevented from absorption with each meal. This mechanism-based approach works alongside your reduced-calorie, lower-fat diet to support weight reduction. Understanding this mechanism helps explain why orlistat may be suitable for adults with a BMI of 30 or above, or 28 with weight-related health conditions.
