Why The Mechanism Matters For Your Weight Loss Success
How Orlistat Actually Works In Your Body
Orlistat works by inhibiting lipase enzymes in your digestive system. These enzymes normally break down dietary fat so it can be absorbed into your body. When orlistat blocks approximately one third of these enzymes, that proportion of fat passes through your system unabsorbed and is excreted naturally. This isn't a brain-based appetite suppressant - it's a targeted fat absorption blocker that works locally in your gut.
Three Orlistat Options: Same Mechanism, Different Strengths
Generic Orlistat 120mg capsules work identically to branded Xenical 120mg - both contain the same active ingredient at prescription strength. A 4-week supply costs £29.69 for generic or £38.69 for Xenical with code EDM10. Alli 60mg offers half the dose for those preferring lower-strength treatment at £26.09 for 4 weeks with EDM10. All three products use the same proven mechanism.
Why Approximately One Third Matters
Orlistat blocks approximately one third of dietary fat - not all fat. This partial blocking is clinically designed to reduce calorie intake while allowing essential fat-soluble vitamin absorption. The remaining two thirds of fat is processed normally. This measured approach explains why orlistat works best with a reduced-calorie, lower-fat diet rather than as a standalone treatment.
Clinical Evidence Behind The Mechanism
The lipase-blocking mechanism has been extensively studied in clinical trials. When combined with dietary changes, this targeted fat absorption reduction can support meaningful weight management. The mechanism works meal by meal - if you skip a meal or eat a fat-free meal, you can skip that orlistat dose since there's no dietary fat to block.
