Why Orlistat's Mechanism Makes It Effective
How Orlistat Blocks Fat: The Science Behind Weight Management
Orlistat works through a targeted mechanism that blocks approximately one third of the fat you eat from being absorbed. Unlike appetite suppressants that act on your brain, orlistat works locally in your digestive system by inhibiting lipase enzymes responsible for breaking down dietary fat. When these enzymes are blocked, unabsorbed fat passes naturally through your body instead of contributing calories. This proven mechanism makes orlistat an effective tool when combined with a reduced-calorie, lower-fat diet.
Different Orlistat Strengths: 120mg vs 60mg
The two main orlistat strengths offer different levels of fat-blocking action. Prescription-strength orlistat 120mg and Xenical 120mg provide maximum lipase inhibition, blocking approximately one third of dietary fat per meal. Generic orlistat 120mg costs £32.99 for 4 weeks (£29.69 with EDM10), whilst branded Xenical costs £42.99 (£38.69 with EDM10) - both containing identical active ingredients. Alli 60mg offers half the dose for those preferring a lower-strength option at £54.99 for 8 weeks (£49.49 with EDM10).
Why Fat-Blocking Works for Weight Management
The mechanism behind orlistat's fat-blocking action directly reduces calorie absorption from your diet. Since fat provides 9 calories per gram - more than double that of carbohydrates or protein - blocking approximately one third of fat intake can significantly impact your daily calorie balance. This creates a calorie deficit essential for weight loss when combined with dietary changes and increased physical activity. The unabsorbed fat serves as a reminder to maintain lower-fat meals, supporting long-term healthy eating habits.
What to Expect: How the Mechanism Affects Your Body
Understanding orlistat's mechanism helps explain the gastrointestinal effects some people experience. These effects - including oily stools, increased bowel frequency, and urgent bowel movements - are direct results of unabsorbed fat passing through your system. Keeping meals to approximately 15g fat each significantly reduces these effects whilst maintaining orlistat's weight management benefits. Most people find effects diminish as they adapt their diet to work with orlistat's fat-blocking action.
