How Orlistat's Mechanism Drives Real Results

How Orlistat and Xenical Work Identically

Orlistat 120mg and Xenical 120mg contain exactly the same active ingredient at identical doses. Both work through the same proven mechanism - inhibiting lipase enzymes in your gut to block approximately one third of dietary fat absorption. This unabsorbed fat passes naturally through your body, reducing calorie intake from fat. The mechanism is identical whether you choose generic orlistat at £29.69 per month or branded Xenical at £38.69 (prices with EDM10). Understanding this mechanism shows why both options deliver the same clinical results.

The Science Behind Fat Blocking

Orlistat works locally in your digestive system, not your brain. It targets pancreatic and gastric lipases - enzymes responsible for breaking down dietary fat. When these enzymes are inhibited, approximately one third of fat from each meal cannot be digested or absorbed. This mechanism provides measurable calorie reduction without affecting protein, carbohydrate, or alcohol absorption. The direct relationship between mechanism and results explains why orlistat supports weight management when combined with a reduced-calorie, lower-fat diet.

Why Understanding the Mechanism Matters

Knowing how orlistat blocks approximately one third of dietary fat helps you maximise results. The mechanism works best when meals contain no more than 15g fat each - higher fat meals increase gastrointestinal side effects as more unabsorbed fat passes through your system. This scientific understanding empowers better food choices. Whether you select orlistat 120mg or Xenical 120mg, the same mechanism delivers consistent fat-blocking effects. Start with our 4-week supply to experience how the mechanism works for you.

Orlistat vs Xenical: Same Mechanism, Different Price

Both orlistat and Xenical work through identical mechanisms at the same 120mg dose. Clinical effectiveness is equivalent - the active ingredient blocks approximately one third of dietary fat regardless of branding. Generic orlistat offers significant savings: 4 weeks costs £29.69 versus £38.69 for Xenical with EDM10. Some patients prefer branded Xenical while others choose generic orlistat for value. Both require prescription following clinical assessment and work through the proven fat-blocking mechanism.
