The Science Behind Orlistat - Why It Works
How Orlistat Blocks Fat Absorption
Orlistat works by inhibiting lipase enzymes in your digestive system. These enzymes normally break down dietary fat so it can be absorbed into your body. When orlistat blocks these enzymes, approximately one third of the fat you eat cannot be digested or absorbed. This unabsorbed fat passes naturally through your body, reducing the calories you absorb from fatty meals.
Why This Mechanism Makes Orlistat Effective
Unlike appetite suppressants that work in your brain, orlistat acts locally in your gut and is not significantly absorbed into your bloodstream. This targeted approach means it directly addresses one of the main sources of excess calories - dietary fat. By blocking approximately one third of fat absorption, orlistat can support weight management when used alongside a reduced-calorie, lower-fat diet.
Generic Orlistat vs Xenical - Same Mechanism, Different Price
Both generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients and work through exactly the same mechanism. The clinical effect is the same - both block approximately one third of dietary fat absorption. Generic orlistat 120mg costs £29.69 for 4 weeks with EDM10, while Xenical costs £38.69 for the same period. Many patients choose generic orlistat for the cost savings, knowing they're getting the same clinical benefit.
What to Expect When Orlistat Starts Working
The fat-blocking effect begins with your first dose. You may notice oily stools or increased bowel movements - this is the unabsorbed fat being eliminated naturally. These effects are more noticeable with high-fat meals, which is why keeping meals low in fat (approximately 15g per meal) helps minimise side effects while maximising the weight management benefits.
Maximising Orlistat's Fat-Blocking Effect
To get the best results from orlistat's mechanism, take one 120mg capsule with each main meal containing fat, up to three times daily. The medication works best when combined with a reduced-calorie, lower-fat diet spread across three meals. This approach optimises the fat-blocking effect while reducing gastrointestinal side effects.
