Understanding how orlistat works helps explain why it's an effective weight management treatment. Orlistat blocks approximately one third of dietary fat absorption by inhibiting lipase enzymes in your gut. This proven mechanism reduces calorie intake from fat alongside a reduced-calorie, lower-fat diet. Generic orlistat 120mg starts from £16.89 (£15.20 with code EDM10), whilst Xenical 120mg costs £21.50 (£19.35 with EDM10). Both contain the same active ingredient and work identically. Order today following an online clinical assessment by UK-licensed prescribers at our GPhC-registered Leicester pharmacy.

Why Orlistat's Mechanism Makes It Worth Buying Today

How Orlistat's Fat-Blocking Mechanism Works

Orlistat works by inhibiting lipase enzymes in your digestive system that normally break down dietary fat. When these enzymes are blocked, approximately one third of the fat you consume cannot be digested or absorbed into your body. This unabsorbed fat passes naturally through your digestive system and is eliminated, reducing your caloric intake from fat. Unlike appetite suppressants that work on the brain, orlistat acts locally in the gut and is not significantly absorbed into your bloodstream.

Treatment Duration: How Long Should You Take Orlistat?

Most patients start with a 4-week supply (84 capsules at £32.99, or £29.69 with EDM10) to assess tolerance and effectiveness. Many continue for 8-12 weeks as part of a structured weight management programme. Generic orlistat 120mg offers excellent value with our 12-week supply at £95.99 (£86.39 with code EDM10), whilst branded Xenical 120mg costs £128.99 (£116.09 with EDM10). Both contain identical 120mg orlistat and work through the same proven mechanism.

Why The Mechanism Proves Orlistat Works

The fat-blocking mechanism is directly measurable - you may notice oily stools or urgency after high-fat meals, which actually demonstrates the medication is working by preventing fat absorption. This visible proof explains why orlistat has remained a trusted prescription weight loss treatment. The mechanism works best when you keep meals low in fat (approximately 15g per meal), which minimises side effects whilst maximising weight management benefits alongside your reduced-calorie diet.

Comparing Orlistat Products: Same Mechanism, Different Prices

Generic orlistat 120mg and Xenical 120mg work through identical mechanisms - both block approximately one third of dietary fat absorption. The clinical effect is the same, but generic orlistat offers significant savings. For an 8-week supply, choose generic orlistat at £63.99 (£57.59 with EDM10) versus Xenical at £86.99 (£78.29 with EDM10). Alli 60mg uses the same mechanism at half the dose for those preferring a lower-strength option starting at £28.99 (£26.09 with EDM10).
