The Science Behind Orlistat - Why It Works for You
How Orlistat Blocks Fat Absorption in Your Body
Orlistat works through a scientifically proven mechanism called lipase inhibition. When you eat fat, your body produces enzymes called lipases to break down that fat for absorption. Orlistat binds to these lipase enzymes in your gut, preventing them from working effectively. This means approximately one third of the fat you consume cannot be digested or absorbed - it simply passes through your body naturally. This mechanism reduces your calorie intake from dietary fat, supporting weight management when combined with a reduced-calorie, lower-fat diet.
Why Understanding the Mechanism Matters
Knowing how orlistat works helps you use it most effectively. Because it acts locally in your digestive system rather than affecting your brain or metabolism, it's a targeted approach to weight management. The unabsorbed fat is eliminated naturally through bowel movements - this is why keeping meals low in fat (approximately 15g per meal) minimises gastrointestinal side effects while maximising effectiveness. Generic orlistat 120mg provides this proven mechanism from £32.99 for 4 weeks (£29.69 with EDM10), while branded Xenical offers the identical effect at £42.99 (£38.69 with EDM10).
Orlistat vs Xenical - Same Mechanism, Different Prices
Both orlistat 120mg and Xenical 120mg contain identical active ingredients working through the same fat-blocking mechanism. Your body cannot tell the difference - both block approximately one third of dietary fat absorption through lipase inhibition. The clinical effect is identical, making generic orlistat an excellent value choice. For a 12-week supply, generic orlistat costs £95.99 (£86.39 with EDM10) compared to Xenical at £128.99 (£116.09 with EDM10) - saving you over £30 while delivering the same proven fat-blocking mechanism.
The Fat-Blocking Process Explained
Here's what happens when you take orlistat with a meal: within your small intestine, orlistat attaches to lipase enzymes before they can break down dietary fat. Approximately 30% of the fat from your meal remains undigested and unabsorbed. This unabsorbed fat travels through your digestive system and is eliminated naturally. The remaining 70% of dietary fat is processed normally, ensuring your body still receives essential fatty acids while reducing overall calorie absorption. This targeted mechanism makes orlistat effective for sustainable weight management.
