Why Understanding Orlistat's Mechanism Matters
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 your calorie intake from dietary sources.
The Science Behind Fat Blocking
Unlike appetite suppressants that work in the brain, orlistat acts locally in your gut. It's not absorbed into your bloodstream in significant amounts, making it a targeted approach to weight management. The mechanism is straightforward: less fat absorbed means fewer calories, which can support weight loss when combined with a reduced-calorie, lower-fat diet.
Generic Orlistat vs Xenical: Same Mechanism, Different Prices
Both generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients and work through the same fat-blocking mechanism. Generic orlistat costs £29.69 for 4 weeks with EDM10, while Xenical costs £38.69 - you save approximately £9 monthly choosing generic. For longer treatment, 12-week supplies cost £86.39 (generic) versus £116.09 (Xenical) with EDM10 discount.
Why the Mechanism Proves Effectiveness
Orlistat's mechanism is measurable and predictable. Clinical studies demonstrate that blocking approximately one third of dietary fat absorption can contribute significantly to weight reduction alongside dietary changes. The fact that you may experience oily stools or other gastrointestinal effects actually confirms the medication is working - it's visible proof that fat is being blocked from absorption.
Optimising Results Through Understanding
Knowing how orlistat works helps you maximise results. Keep meals to approximately 15g fat each to minimise side effects while maintaining effectiveness. The medication works with every meal containing fat, so consistent use alongside your lower-fat diet plan is essential. Take one 120mg capsule with each main meal, up to three times daily.
