Why Understanding the Mechanism Matters for Your Choice
How Orlistat Blocks Fat Absorption
Orlistat works through a precise mechanism called lipase inhibition. When you take orlistat with meals, it binds to lipase enzymes in your gut that normally break down dietary fat. With these enzymes blocked, approximately one third of the fat you eat cannot be digested or absorbed into your body. This unabsorbed fat passes naturally through your digestive system and is excreted. The remaining two thirds of dietary fat is still processed normally, which is why orlistat is not a complete fat blocker.
Why This Mechanism Proves Orlistat Works
Unlike appetite suppressants that act on the brain, orlistat's local action in the gut provides measurable, predictable results. You can literally see the unabsorbed fat being eliminated from your body. This visible proof demonstrates the medication is working as designed. The mechanism also explains why maintaining a lower-fat diet is essential - high-fat meals increase gastrointestinal side effects as more unabsorbed fat passes through your system.
Prescription Orlistat 120mg vs Alli 60mg
Prescription-strength orlistat 120mg blocks approximately one third of dietary fat, whilst Alli 60mg at half the dose provides a milder effect. Generic orlistat 120mg costs from £15.20 per 2-week supply with code EDM10, offering identical fat-blocking action to branded Xenical at £19.35. Our 4-week supply at £29.69 (orlistat) or £38.69 (Xenical) provides better value for sustained weight management. All require clinical assessment by our UK-licensed prescribers who review your eligibility based on BMI and health factors.
The Science Behind Lipase Inhibition
Orlistat specifically targets pancreatic and gastric lipases - the enzymes responsible for breaking down triglycerides into absorbable fatty acids. By forming covalent bonds with these enzymes, orlistat creates a reversible but long-lasting inhibition. This targeted approach means orlistat doesn't affect carbohydrate or protein digestion, focusing solely on dietary fat. The mechanism begins working within hours of taking your first capsule with a fat-containing meal.
