The Fat-Blocking Mechanism That Drives Results
How Orlistat's Fat-Blocking Mechanism Works
Orlistat 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 these enzymes, approximately one third of the fat you eat cannot be digested or absorbed. This unabsorbed fat passes naturally through your body, reducing calorie intake from dietary sources.
This mechanism is identical whether you choose generic orlistat 120mg (from £16.89) or branded Xenical 120mg (from £21.50). Both contain the same active ingredient at the same dose, blocking approximately one third of dietary fat with equal effectiveness.
Why This Mechanism Proves Orlistat Works
Unlike appetite suppressants that affect brain chemistry, orlistat's mechanism is mechanical and localised. It physically prevents fat absorption in your gut without entering your bloodstream significantly. This targeted approach means you can see evidence of the medicine working through gastrointestinal effects - proof that approximately one third of dietary fat is being blocked rather than absorbed.
The mechanism works best when you consume moderate amounts of fat per meal (approximately 15g). Higher fat meals increase side effects as more unabsorbed fat passes through your system. Lower fat meals minimise side effects while maintaining the weight management benefits.
Orlistat vs Xenical: Identical Fat-Blocking Action
The key difference between generic orlistat and Xenical isn't how they work - both use the identical fat-blocking mechanism. The difference is cost. Generic orlistat 120mg (84 capsules) costs £32.99 (£29.69 with EDM10), while Xenical costs £42.99 (£38.69 with EDM10). That's approximately £9 monthly savings for the same clinical effect.
Alli 60mg uses the same mechanism but at half the dose, blocking a smaller proportion of dietary fat. At £28.99 for 42 capsules (£26.09 with EDM10), Alli offers a lower-strength option for those preferring gradual introduction to fat-blocking treatment.
Maximising Results Through Understanding
Knowing how orlistat works helps you use it effectively. The fat-blocking mechanism requires dietary fat to be present - if you eat a fat-free meal, you can skip that dose. The medicine works meal by meal, so consistency with a reduced-calorie, lower-fat diet enhances results.
Take one 120mg capsule with each main meal containing fat, up to three times daily. The mechanism begins working within hours, blocking approximately one third of fat from that specific meal. Results build over time as reduced calorie absorption from fat supports your weight management goals.
