Why Understanding Orlistat's Mechanism Matters for Results
How Orlistat's Fat-Blocking Mechanism Works
Orlistat works by inhibiting lipase enzymes in your digestive system that normally break down dietary fats. When these enzymes are blocked, approximately one third of the fat you consume cannot be digested or absorbed into your body. This unabsorbed fat passes naturally through your digestive system and is eliminated. The mechanism is purely local - orlistat acts in your gut rather than being absorbed into your bloodstream, making it fundamentally different from appetite suppressants that affect your brain.
Empty Stomach vs With Meals: Timing That Maximises Results
Taking orlistat on an empty stomach provides no benefit because there's no dietary fat present for the medication to act upon. The mechanism specifically targets fat from food, so timing with meals is crucial. Take one 120mg capsule with each main meal containing fat - immediately before, during, or up to one hour after eating. If you skip a meal or eat something fat-free, you can skip that dose. Our generic orlistat 120mg costs £32.99 for 84 capsules (4 weeks), reduced to £29.69 with code EDM10.
Why This Mechanism Proves Orlistat Works
The fat-blocking mechanism provides measurable proof that orlistat is working. When unabsorbed fat is eliminated, you may notice oily stools or increased bowel frequency - these gastrointestinal effects actually demonstrate the medication is successfully preventing fat absorption. This isn't a placebo effect or wishful thinking; it's biochemical evidence that approximately one third of your dietary fat isn't contributing to your calorie intake. Combined with a reduced-calorie, lower-fat diet, this mechanism can support meaningful weight management.
Orlistat vs Xenical vs Alli: Same Mechanism, Different Strengths
All three products work through identical lipase inhibition. Generic orlistat 120mg and branded Xenical 120mg contain the same active ingredient at the same strength, providing the same fat-blocking effect. The key difference is cost - Xenical costs £42.99 for 4 weeks compared to £32.99 for generic orlistat. Alli contains 60mg orlistat (half the prescription strength), blocking a smaller proportion of dietary fat.

Maximising Results Through Smart Meal Planning
Understanding orlistat's mechanism helps you plan meals that minimise side effects while maximising benefits. Keep each meal to approximately 15g fat or less - when there's less fat to block, you'll experience fewer gastrointestinal effects while still benefiting from the fat absorption reduction. High-fat meals overwhelm the system, leading to more pronounced side effects as larger amounts of unabsorbed fat are eliminated. Our 12-week supply (252 capsules) costs £95.99, reduced to £86.39 with EDM10, giving you time to establish this sustainable eating pattern.
