Why Orlistat's Fat-Blocking Mechanism Makes It Effective
How Orlistat's Fat-Blocking Mechanism Actually Works
Orlistat works through a scientifically proven mechanism called lipase inhibition. When you take orlistat 120mg with meals, it blocks enzymes in your digestive system that normally break down dietary fat. This means approximately one third of fat from your food cannot be absorbed and passes naturally through your body. The remaining two thirds of fat is still processed normally - orlistat isn't a complete fat blocker, but this partial blocking can significantly reduce calorie intake from dietary fat when combined with a lower-fat diet.
Generic Orlistat vs Xenical: Identical Fat-Blocking Power
Both generic orlistat 120mg and branded Xenical 120mg work through exactly the same mechanism - they contain identical amounts of the active ingredient that inhibits lipase enzymes. The fat-blocking effect is clinically equivalent whether you choose generic orlistat at £29.69 for 4 weeks or Xenical at £38.69 for 4 weeks (both with EDM10 code). Many patients choose generic orlistat for the cost savings while getting the same proven fat-blocking mechanism that makes this treatment effective.
Why Understanding the Mechanism Matters for Your Success
Knowing how orlistat works helps you use it effectively. Because it blocks approximately one third of dietary fat absorption, keeping your meals lower in fat (around 15g per meal) maximises the weight management benefits while minimising gastrointestinal side effects. The unabsorbed fat that passes through your system is actually proof the medication is working - these effects reduce significantly when you maintain a lower-fat diet alongside treatment.
Alli 60mg: Half-Strength Fat Blocking
Alli contains 60mg orlistat - exactly half the prescription dose. While it uses the same lipase-inhibiting mechanism, it blocks a smaller proportion of dietary fat compared to the full 120mg prescription strength. Available at £26.09 for 4 weeks with EDM10, Alli may suit those preferring a gentler introduction to fat-blocking treatment, though the 120mg prescription strength offers more significant fat absorption reduction.
