The Science Behind Orlistat - Why It Works So Well
How Orlistat Blocks Fat Absorption
Orlistat works through a scientifically-proven mechanism that targets lipase enzymes in your digestive system. These enzymes normally break down dietary fat so it can be absorbed into your bloodstream. When you take orlistat 120mg with meals, it inhibits these lipase enzymes, preventing approximately one third of the fat you eat from being digested and absorbed. This unabsorbed fat passes naturally through your body, reducing your calorie intake from dietary fat.
Generic orlistat 120mg costs just £32.99 for a 4-week supply (£29.69 with EDM10), while branded Xenical 120mg costs £42.99 for the same period (£38.69 with EDM10). Both contain identical active ingredients and work through the same proven mechanism.
Why Understanding the Mechanism Matters
Knowing how orlistat works helps you use it most effectively. Because it acts locally in your gut rather than affecting your brain or metabolism, you can expect predictable results when combined with a reduced-calorie, lower-fat diet. The medication doesn't work on carbohydrates or protein - only on dietary fat - which is why keeping fat intake to approximately 15g per meal maximises effectiveness while minimising side effects.
This targeted approach makes orlistat particularly suitable for those following structured eating plans. The mechanism means you'll see the best results when you maintain consistent, lower-fat meals throughout your treatment period.
Orlistat vs Xenical - Same Mechanism, Different Prices
Both generic orlistat 120mg and branded Xenical 120mg work through identical mechanisms. They contain the same active ingredient at the same dose and block approximately one third of dietary fat absorption equally effectively. The key difference is cost - choosing generic orlistat saves approximately £9 per month compared to Xenical.
For longer treatment periods, the savings are even more significant. An 8-week supply of generic orlistat costs £63.99 (£57.59 with EDM10) compared to £86.99 for Xenical (£78.29 with EDM10) - that's over £20 in savings while getting exactly the same clinical effect.
