Why Orlistat's Mechanism Makes It Effective
How Orlistat Blocks Fat Absorption
Orlistat works through a scientifically proven mechanism that inhibits lipase enzymes in your digestive system. These enzymes normally break down dietary fat for absorption, but orlistat blocks approximately one third of this process. The unabsorbed fat passes naturally through your body, reducing the calories absorbed from fatty meals. This local action in the gut makes orlistat different from appetite suppressants that affect your brain.
Why "Approximately One Third" Matters
Understanding that orlistat blocks approximately one third of dietary fat helps set realistic expectations. It's not a complete fat blocker - your body still absorbs two thirds of dietary fat normally. This partial blocking is clinically proven to support weight management when combined with a reduced-calorie, lower-fat diet. Generic orlistat 120mg costs just £29.69 for 4 weeks with EDM10, making this proven mechanism accessible and affordable.
Orlistat vs Xenical: Same Mechanism, Different Price
Both generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients and work through the same fat-blocking mechanism. The clinical effect is equivalent - approximately one third of dietary fat blocked in both cases. Generic orlistat offers significant savings at £29.69 for 4 weeks compared to Xenical at £38.69 with EDM10. Our GPhC-registered pharmacy stocks both options for next-day delivery across the UK.
Alli 60mg: Lower Dose, Same Mechanism
Alli contains orlistat at half the prescription strength (60mg vs 120mg). It works through the same lipase-inhibiting mechanism but blocks a smaller proportion of dietary fat. Available at £26.09 for 4 weeks with EDM10, Alli may suit those preferring a gentler introduction to orlistat treatment. All three products require the same commitment to a lower-fat diet for optimal results.
