The Science Behind Why Orlistat Works
How Orlistat Blocks Fat Absorption
Orlistat works through a simple yet effective mechanism in your digestive system. The active ingredient inhibits lipase enzymes responsible for breaking down dietary fat. When these enzymes are blocked, approximately one third of the fat you consume cannot be digested or absorbed into your body. This unabsorbed fat passes naturally through your digestive system, reducing the calories available for storage. Unlike stimulant-based weight loss treatments, orlistat acts locally in your gut and is not significantly absorbed into your bloodstream.
Why This Mechanism Proves Effectiveness
The lipase inhibition mechanism provides measurable, predictable results. Each gram of blocked fat represents 9 calories that cannot contribute to weight gain. With orlistat blocking approximately one third of dietary fat absorption, you're reducing fat-derived calories with every meal. This explains why orlistat works best alongside a reduced-calorie, lower-fat diet - the combination maximises calorie reduction whilst minimising gastrointestinal side effects. Generic orlistat 120mg costs from £29.69 for 4 weeks with EDM10, whilst branded Xenical costs £38.69 - both delivering identical fat-blocking effects.
Orlistat vs Xenical: Same Mechanism, Different Prices
Both generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients working through the same lipase inhibition mechanism. Clinical effectiveness is equivalent - the key difference lies in cost. Generic orlistat offers significant savings: 12-week supplies cost £86.39 with EDM10 compared to £116.09 for Xenical. Some patients prefer branded Xenical, whilst others choose generic orlistat for better value. Our UK-licensed prescribers can help determine which option suits your weight management goals and budget during your online consultation.
Maximising Orlistat's Fat-Blocking Effect
Understanding orlistat's mechanism helps optimise treatment outcomes. Take one 120mg capsule with each main meal containing fat - up to three capsules daily. If a meal contains no fat, you can skip that dose since there's no dietary fat for orlistat to block. Spreading daily fat intake evenly across three meals (approximately 15g fat per meal) maximises the fat-blocking benefit whilst reducing side effects. Remember: orlistat doesn't affect carbohydrates, protein, or alcohol calories - only dietary fat absorption.
