Why Understanding How Orlistat Works Matters
The Science Behind Orlistat's Fat-Blocking Mechanism
Orlistat works through a targeted mechanism that inhibits lipase enzymes in your digestive system. These enzymes normally break down dietary fat so it can be absorbed into your body. When orlistat blocks these enzymes, approximately one third of the fat you eat cannot be digested or absorbed. This unabsorbed fat passes naturally through your system, reducing the calories your body takes in from dietary fat.
This mechanism is why orlistat has become a trusted prescription weight loss treatment. Unlike appetite suppressants that act on the brain, orlistat works locally in your gut and is not significantly absorbed into your bloodstream. You can see this mechanism working - it's the reason for the gastrointestinal effects that occur when eating higher-fat meals.
Generic Orlistat vs Xenical: Same Proven Mechanism
Both generic Orlistat 120mg and branded Xenical 120mg contain identical active ingredients and work through exactly the same fat-blocking mechanism. Generic Orlistat offers this proven mechanism from just £15.20 for a 2-week supply (42 capsules) with code EDM10, while branded Xenical costs £19.35 for the same supply. The 4-week supply (84 capsules) costs £29.69 for generic orlistat versus £38.69 for Xenical with EDM10 discount.
Alli 60mg uses the same mechanism but at half the dose, blocking a smaller proportion of dietary fat. A 4-week supply costs £26.09 with EDM10. All three options work through identical fat-blocking mechanisms - the choice often comes down to dose preference and budget.
How the Mechanism Supports Your Weight Management
Understanding orlistat's mechanism helps explain why it works best alongside a reduced-calorie, lower-fat diet. When you keep fat intake to approximately 15g per meal, you maximise the medication's effectiveness while minimising side effects. The mechanism is dose-dependent - higher fat meals mean more unabsorbed fat and more noticeable gastrointestinal effects.
This mechanism also explains why orlistat requires a prescription at 120mg strength. The fat-blocking effect is significant enough that clinical assessment ensures it's appropriate for your individual circumstances. Our UK-licensed prescribers assess suitability through an online consultation, with prescriptions issued where clinically appropriate.
