Why Understanding Orlistat's Mechanism Matters
How Orlistat Works in Your Digestive System
Orlistat works through a clinically proven mechanism that blocks approximately one third of the fat you eat from being absorbed. When you take orlistat with a meal, it inhibits lipase enzymes in your gut that normally break down dietary fat. This means roughly one third of the fat passes through your body undigested and is eliminated naturally, reducing your calorie intake from fat.
Generic orlistat 120mg provides this proven mechanism at £32.99 for 4 weeks (£29.69 with EDM10), while branded Xenical offers the identical effect at £42.99 for 4 weeks (£38.69 with EDM10). Both require prescription following clinical assessment.
How Quickly Does Orlistat Take to Work?
Orlistat begins working immediately with your first dose. Each 120mg capsule taken with a meal containing fat will block approximately one third of that meal's fat absorption. You may notice oily stools within 24-48 hours - this is actually evidence the medication is working by eliminating unabsorbed fat.
For sustained weight management results, orlistat works best when taken consistently three times daily with main meals, alongside a reduced-calorie, lower-fat diet. Our 8-week supply (168 capsules) costs £63.99 (£57.59 with EDM10), providing excellent value for consistent treatment.
Clinical Evidence Behind Orlistat's Mechanism
Orlistat's fat-blocking mechanism has been extensively studied and proven effective in clinical trials. Unlike appetite suppressants that work on the brain, orlistat acts locally in your digestive system, targeting the specific enzymes responsible for fat digestion. This targeted approach means approximately one third of dietary fat is eliminated rather than stored as body fat.
Understanding this mechanism helps explain why maintaining a lower-fat diet (around 30% of calories from fat) is essential - it maximises the medication's effectiveness while minimising gastrointestinal side effects.
