Understanding How Orlistat Works - Your Buying Decision
How Orlistat Blocks Fat Absorption
Orlistat works through a clinically proven mechanism that blocks approximately one third of dietary fat from being absorbed by your body. Unlike appetite suppressants that act on the brain, orlistat works locally in your digestive system by inhibiting lipase enzymes responsible for breaking down fat. When these enzymes are blocked, unabsorbed fat passes naturally through your system, reducing the calories your body takes in from meals.
Why the Mechanism Matters for Weight Management
This fat-blocking action means orlistat can support weight loss as part of a structured programme combining a reduced-calorie, lower-fat diet with increased physical activity. The medication works best when meals contain no more than 15g of fat each - this also helps minimise gastrointestinal side effects that occur when unabsorbed fat is eliminated from your body.
Generic Orlistat vs Xenical - Same Mechanism, Better Value
Both generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients working through the same fat-blocking mechanism. Generic orlistat offers significant savings - a 4-week supply costs £32.99 (£29.69 with EDM10) compared to Xenical at £42.99 (£38.69 with EDM10). Clinical effectiveness is identical, making generic orlistat the cost-effective choice for most patients.
Alli 60mg - Lower Dose Option
Alli contains half the dose of prescription-strength orlistat, blocking a smaller proportion of dietary fat. At 60mg, Alli may be suitable for those preferring a gentler starting approach, though the fat-blocking effect is correspondingly reduced compared to the full 120mg prescription dose.
