How Orlistat's Fat-Blocking Mechanism Works

Orlistat works through a scientifically proven mechanism that blocks approximately one third of the fat you eat from being absorbed. Unlike appetite suppressants that act on the brain, orlistat works locally in your digestive system by inhibiting pancreatic and gastric lipase enzymes. These enzymes are responsible for breaking down dietary fats into smaller molecules that can be absorbed. When orlistat blocks these enzymes, approximately one third of dietary fat cannot be digested and passes naturally through your body.

Why This Mechanism Makes Orlistat Effective

The lipase inhibition mechanism is why orlistat has become a trusted prescription weight loss treatment. By reducing fat absorption by approximately one third, orlistat helps create the calorie deficit needed for weight management alongside a reduced-calorie, lower-fat diet. This proven mechanism works consistently - the more fat in your meal, the more orlistat can help block absorption, though keeping meals lower in fat reduces side effects.

Orlistat 120mg vs Xenical vs Alli - Same Mechanism, Different Strengths

All three products work through the same fat-blocking mechanism. Generic orlistat 120mg (from £29.69 for 4 weeks with EDM10) and branded Xenical 120mg (from £38.69 for 4 weeks with EDM10) contain identical active ingredients and block approximately one third of dietary fat. Alli 60mg offers the same mechanism at half the dose, making it a lower-strength option for £26.09 (4-week supply with EDM10).

Scientific Proof This Mechanism Works

Clinical studies demonstrate orlistat's lipase inhibition consistently blocks approximately one third of dietary fat absorption. This isn't theoretical - the mechanism is measurable and proven. Unabsorbed fat appears in stools, providing visible evidence the medication is working. This mechanism explains why orlistat requires a reduced-calorie, lower-fat diet to work effectively and minimise gastrointestinal effects.
