Understanding Orlistat's Fat-Blocking Mechanism
How Orlistat Blocks Fat Absorption
Orlistat works by blocking lipase enzymes in your digestive system that break down dietary fat. When these enzymes are inhibited, approximately one third of the fat you consume cannot be absorbed into your bloodstream. This unabsorbed fat passes naturally through your body, reducing the calories absorbed from meals. The mechanism is local - orlistat acts in your gut rather than your brain, making it fundamentally different from appetite suppressants.
Why Weight Loss Results Vary
Individual responses to orlistat depend on several factors including your starting weight, diet composition, and adherence to a lower-fat eating plan. The medication blocks approximately one third of dietary fat, but if your meals contain minimal fat, there's less fat available to block. This is why combining orlistat with a structured, reduced-calorie diet maximises effectiveness. Our UK-licensed prescribers assess your individual circumstances during the online consultation process.
Orlistat vs Xenical - Same Mechanism, Different Prices
Both generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients and work through the same fat-blocking mechanism. At EverydayMeds, generic orlistat costs £29.69 for 4 weeks with EDM10, while Xenical costs £38.69 - that's £9 monthly savings for the same clinical effect. Alli 60mg provides half the dose at £26.09 for 4 weeks, blocking a smaller proportion of dietary fat but with typically milder gastrointestinal effects.
Maximising Orlistat's Effectiveness
To optimise results, keep meals to approximately 15g fat each - this reduces side effects while allowing orlistat's mechanism to work effectively. The medication should be taken three times daily with main meals containing fat, or skipped if a meal contains no fat. A daily multivitamin taken at bedtime supports nutrition while using orlistat, as the medication may reduce absorption of fat-soluble vitamins A, D, E, and K.
