The Science Behind Orlistat's Fat-Blocking Action
How Orlistat's Fat-Blocking Mechanism Works
Orlistat works through a simple yet effective mechanism in your digestive system. When you eat fat, enzymes called lipases break it down so your body can absorb it. Orlistat inhibits these lipase enzymes, preventing approximately one third of the fat in your meals from being digested and absorbed. This unabsorbed fat passes naturally through your body and is excreted.
Unlike appetite suppressants that work on your brain, orlistat acts locally in your gut and is not significantly absorbed into your bloodstream. This targeted approach makes it a unique weight management tool when combined with a reduced-calorie, lower-fat diet.
Why Understanding This Mechanism Matters
Knowing how orlistat blocks approximately one third of dietary fat helps you understand why it works and how to use it effectively. The mechanism is directly related to what you eat – the more fat in your meal, the more orlistat has to work with. However, keeping fat intake low (around 15g per meal) minimises side effects while maximising results.
At EverydayMeds, we stock both generic orlistat 120mg from £29.69 (4 weeks with EDM10) and branded Xenical 120mg from £38.69 (4 weeks with EDM10). Both contain identical active ingredients and work through the same proven fat-blocking mechanism.
Clinical Evidence Behind the Fat-Blocking Action
The mechanism of orlistat has been extensively studied and proven effective. By blocking approximately one third of dietary fat absorption, orlistat can support weight management as part of a structured programme including diet and exercise. This isn't a complete fat blocker – your body still absorbs the majority of fat you consume, but reducing absorption by approximately one third can contribute significantly to creating the calorie deficit needed for weight loss.

Orlistat vs Xenical: Same Mechanism, Different Prices
Whether you choose generic orlistat 120mg or branded Xenical 120mg, you're getting the same lipase-inhibiting mechanism that blocks approximately one third of dietary fat. The clinical effect is identical – the key difference is cost. Generic orlistat offers excellent value at £63.99 for 8 weeks (£57.59 with EDM10), while Xenical 120mg costs £86.99 for 8 weeks (£78.29 with EDM10).
For those preferring a lower-strength option, Alli 60mg uses the same mechanism at half the dose, starting from £49.49 for 8 weeks with code EDM10.
