Why Orlistat's Fat-Blocking Mechanism Works
How Orlistat's Fat-Blocking Mechanism Works
Orlistat works by targeting lipase enzymes in your digestive system. These enzymes normally break down dietary fat so your body can absorb it. When you take orlistat, it inhibits approximately one third of these lipase enzymes, preventing roughly one third of the fat you eat from being digested and absorbed. The unabsorbed fat passes naturally through your body, effectively reducing the calories you absorb from fat-containing meals.
Why This Mechanism Makes Orlistat Effective
Unlike appetite suppressants that work in the brain, orlistat's mechanism is entirely gut-based. This local action means it directly reduces calorie absorption from dietary fat without systemic effects. When you eat a meal containing 30g fat, orlistat may help block approximately 10g from absorption - that's roughly 90 fewer calories per meal. Generic orlistat 120mg costs just £29.69 for 4 weeks with EDM10, making this proven mechanism affordable.
Orlistat 60mg vs 120mg Dosage Differences
Alli 60mg contains half the dose of prescription-strength orlistat, blocking a smaller proportion of dietary fat. The 120mg prescription dose (available as generic orlistat from £15.20 or branded Xenical from £19.35 with EDM10) provides the full fat-blocking mechanism. Both work identically - inhibiting lipase enzymes - but 120mg offers more comprehensive fat absorption blocking for those suitable for prescription treatment.
What to Expect When Orlistat's Mechanism Activates
When orlistat blocks fat absorption, the unabsorbed fat must leave your body naturally. This may cause oily stools, urgent bowel movements, or oily discharge - these effects actually demonstrate the mechanism working. Keeping fat intake low (approximately 15g per meal) minimises these effects while maintaining orlistat's fat-blocking benefits. These gastrointestinal effects typically reduce as your diet adapts.
