Why Orlistat's Proven Mechanism Makes It Effective
How Orlistat 120mg Blocks Fat Absorption
Orlistat works through a scientifically proven mechanism that targets lipase enzymes in your digestive system. These enzymes are responsible for breaking down dietary fat so it can be absorbed into your body. Orlistat inhibits approximately one third of these lipases, meaning roughly one third of the fat you eat cannot be digested or absorbed. This unabsorbed fat passes naturally through your digestive system and is eliminated from your body.
This mechanism is why orlistat 120mg requires a prescription and clinical assessment. Generic orlistat costs from £29.69 for 4 weeks with code EDM10, whilst branded Xenical costs £38.69 for the same period - both containing identical 120mg doses with the same fat-blocking effect.
Why This Mechanism Proves Orlistat Works
Unlike appetite suppressants that work on brain chemistry, orlistat's action is direct and measurable. When you take orlistat 120mg capsules three times daily with meals containing fat, you're actively preventing approximately one third of that dietary fat from contributing to your calorie intake. The remaining two thirds of fat is processed normally by your body.
This proven mechanism explains why orlistat is prescribed alongside a reduced-calorie, lower-fat diet. By keeping your meals to around 15g fat each, you minimise side effects whilst maximising the weight management benefits. Our 8-week supply (168 capsules) costs £57.59 with EDM10 - enough to establish this effective routine.
Orlistat vs Xenical - Same Fat-Blocking Mechanism
Both generic orlistat 120mg and branded Xenical 120mg work through identical mechanisms. The active ingredient is the same, the dose is the same, and the fat-blocking effect is the same - approximately one third of dietary fat absorption is prevented with either product.
The key difference is cost. Generic orlistat represents significant savings - our 12-week supply costs £86.39 with EDM10 compared to £116.09 for branded Xenical. Both require the same online clinical assessment by our UK-licensed prescribers and both are dispensed by our GPhC-registered pharmacy in Leicester.
What to Expect When Orlistat Starts Working
Because orlistat works immediately in your gut, you may notice gastrointestinal effects within 24-48 hours of starting treatment. These effects - including oily stools or oily spotting - are actually evidence that the mechanism is working and fat is being blocked from absorption.
Most patients find these effects reduce significantly when they adapt to a lower-fat diet. This is why our prescribers emphasise that orlistat works best when fat intake is distributed evenly across three main meals, with no more than approximately 15g fat per meal.
