Why Understanding Orlistat's Mechanism Matters
How Orlistat 120mg Actually Works in Your Body
Xenical 120mg contains orlistat, which works by inhibiting lipase enzymes in your digestive system. These enzymes normally break down dietary fat so your body can absorb it. When orlistat blocks approximately one third of these lipases, that portion of fat cannot be digested or absorbed. This unabsorbed fat passes naturally through your digestive system and is excreted, reducing your calorie intake from dietary fat.
The Science Behind Fat Blocking
Unlike appetite suppressants that affect your brain, orlistat works locally in your gut. It's not significantly absorbed into your bloodstream, making it a targeted approach to weight management. When you take one 120mg capsule with each main meal containing fat, orlistat gets to work immediately on the fat in that specific meal. This mechanism explains why timing matters - take it immediately before, during, or up to one hour after eating.
Xenical vs Generic Orlistat - Same Proven Mechanism
Both Xenical 120mg (£38.69 for 4 weeks with EDM10) and generic orlistat 120mg (£29.69 for 4 weeks with EDM10) contain identical active ingredients. The fat-blocking mechanism is clinically equivalent. Generic orlistat offers the same lipase inhibition at £9 less per month, whilst some patients prefer branded Xenical. Both require prescription following clinical assessment by our UK-licensed prescribers.
Why "Approximately One Third" Matters
Orlistat blocks approximately one third of dietary fat - never 100%. This partial blocking is clinically proven and explains why you must still follow a reduced-calorie, lower-fat diet. The remaining two thirds of fat is absorbed normally, so controlling your fat intake per meal (around 15g) minimises side effects whilst maximising the weight management benefits of the blocked fat.
What This Mechanism Means for Your Weight Management
Understanding how orlistat works helps you use it effectively. Each blocked gram of fat represents 9 calories not absorbed by your body. Over time, this calorie reduction can support weight loss alongside your diet and exercise programme. The mechanism also explains why side effects like oily stools occur - they're actually proof the medication is working by preventing fat absorption.
