Understanding the Mechanism to Make Your Purchase Decision
How Orlistat Blocks Fat Absorption
Orlistat works through a proven mechanism that targets lipase enzymes in your digestive system. These enzymes normally break down dietary fat so it can be absorbed into your body. Orlistat inhibits approximately one third of these enzymes, meaning roughly one third of the fat you eat passes through your system undigested and is naturally excreted. This isn't a stimulant or appetite suppressant - it's a fat blocker that works locally in your gut.
Why This Mechanism Proves Orlistat Works
The fact that orlistat blocks fat absorption through enzyme inhibition demonstrates its clinical effectiveness. When you eat a meal containing fat, orlistat immediately begins working to prevent approximately one third of that fat from being absorbed. The remaining two thirds is processed normally. This targeted action means fewer calories from dietary fat enter your body, supporting weight management when combined with a reduced-calorie, lower-fat diet.
Orlistat 120mg vs Xenical vs Alli - Same Mechanism
Whether you choose generic orlistat 120mg (£32.99 for 4 weeks), branded Xenical 120mg (£42.99 for 4 weeks), or Alli 60mg (£28.99 for 4 weeks), the mechanism remains the same. All contain orlistat as the active ingredient that blocks lipase enzymes. The 120mg prescription versions block more fat than the 60mg Alli, but all work through identical enzyme inhibition. Use code EDM10 for 10% off any option.
Why the Mechanism Matters for Your Results
Understanding how orlistat blocks approximately one third of dietary fat helps you use it effectively. The mechanism works best when you eat lower-fat meals - high-fat meals increase gastrointestinal side effects as more unabsorbed fat passes through your system. This natural consequence actually proves the medicine is working. Keep meals to roughly 15g fat each for optimal results and minimal side effects.
