How Orlistat Blocks Fat Absorption
Orlistat works through a targeted mechanism that inhibits lipase enzymes in your digestive system. These enzymes are responsible for breaking down dietary fat into smaller molecules that can be absorbed into your bloodstream. When you take orlistat 120mg with meals, it blocks approximately one third of the fat you eat from being digested and absorbed. This unabsorbed fat passes naturally through your body and is excreted.
Why This Mechanism Makes Orlistat Effective
Unlike appetite suppressants that work on your brain, orlistat acts locally in your gut. This means it directly reduces the calories you absorb from dietary fat without systemic effects. Generic orlistat 120mg costs just £29.69 for a 4-week supply with code EDM10, while branded Xenical 120mg is £38.69 for the same period. Both contain identical active ingredients and work through the same fat-blocking mechanism.
Scientific Evidence Behind Fat Blocking
Clinical studies demonstrate that orlistat blocks approximately one third of dietary fat absorption when taken with meals containing fat. This mechanism is most effective when combined with a reduced-calorie, lower-fat diet where each meal contains no more than 15g of fat. The fat-blocking action is directly proportional to meal fat content - higher fat meals increase both effectiveness and potential gastrointestinal side effects.
Comparing Orlistat Strengths and Their Mechanisms
Prescription orlistat 120mg and Xenical 120mg work identically, blocking the same proportion of dietary fat. Alli 60mg contains half the dose, blocking a smaller amount of fat absorption. Our 8-week orlistat supply costs £57.59 with EDM10, compared to Xenical at £78.29. The mechanism remains the same regardless of which option you choose, with higher doses providing greater fat-blocking effects.
What to Expect When Orlistat Starts Working
You may notice orlistat's fat-blocking mechanism working within 24-48 hours through changes in bowel movements. Oily or fatty stools indicate the medicine is successfully preventing fat absorption. These effects are more pronounced with higher-fat meals and typically reduce when you follow a lower-fat diet. This visible evidence demonstrates the mechanism in action.
Maximising Orlistat's Fat-Blocking Mechanism
To optimise how orlistat works, take one capsule with each main meal containing fat. The timing matters - take it immediately before, during, or up to one hour after eating. If a meal contains no fat, you can skip that dose. Our 12-week orlistat supply at £86.39 with EDM10 provides comprehensive treatment duration to establish this routine and see sustained results from the fat-blocking mechanism.
