How Orlistat's Fat Blocking Mechanism Works
Understanding Orlistat's Proven Fat Absorption Mechanism
Orlistat works through a scientifically-proven mechanism that blocks approximately one third of dietary fat absorption in your digestive system. Unlike appetite suppressants that affect the brain, orlistat acts locally in your gut by inhibiting lipase enzymes responsible for breaking down dietary fat. This unabsorbed fat passes naturally through your body, reducing the calories absorbed from each meal. The mechanism is identical whether you choose generic orlistat 120mg (from £15.20 for 2 weeks with EDM10) or branded Xenical 120mg (from £19.35 with EDM10).
Why 120mg Prescription Strength Outperforms Alli 60mg
The key difference between prescription orlistat and Alli lies in dosage strength and fat-blocking capacity. Prescription orlistat 120mg provides double the dose of Alli's 60mg, delivering more potent lipase inhibition and enhanced fat blocking. While Alli costs £26.09 for a 4-week supply, generic orlistat 120mg costs just £29.69 for 4 weeks with code EDM10 - offering superior potency at comparable pricing. The stronger dose means more effective dietary fat blocking, supporting greater weight management potential when combined with a reduced-calorie, lower-fat diet.
Clinical Mechanism: Lipase Inhibition in Action
Orlistat's mechanism centres on reversible inhibition of gastric and pancreatic lipases - the enzymes that digest dietary triglycerides. By blocking these enzymes, orlistat prevents approximately one third of consumed fat from being broken down into absorbable fatty acids and glycerol. Instead, this undigested fat is eliminated naturally through bowel movements. This mechanism explains why gastrointestinal effects occur - they're evidence the medicine is working to block fat absorption. The effect is dose-dependent, which is why 120mg prescription strength provides superior fat blocking compared to 60mg Alli.
Why the Mechanism Makes Orlistat Worth Buying Today
Understanding orlistat's mechanism proves its clinical effectiveness and explains why it's prescribed worldwide for weight management. The approximately one-third fat absorption blocking provides measurable calorie reduction from each meal, supporting weight loss alongside dietary changes. With 8-week supplies of generic orlistat available for £57.59 (with EDM10) compared to Alli's £49.49 for the same period, the prescription strength offers better value per milligram of active ingredient.
