Why Understanding Orlistat's Mechanism Matters Before You Buy
How Orlistat Blocks Fat Absorption
Orlistat works through a precise mechanism that targets lipase enzymes in your digestive system. These enzymes normally break down dietary fat so it can be absorbed into your body. When you take orlistat 120mg with meals, it inhibits approximately one third of these lipase enzymes, preventing that proportion of fat from being digested. The unabsorbed fat passes naturally through your body rather than being stored. This mechanism makes orlistat fundamentally different from stimulant-based weight loss medications that act on the brain - it works locally in your gut where fat digestion occurs.
Why the Mechanism Proves Orlistat Works
Understanding this fat-blocking mechanism explains why orlistat can support weight management when used alongside a reduced-calorie, lower-fat diet. Each gram of fat contains 9 calories, so blocking approximately one third of dietary fat absorption directly reduces calorie intake from fat. Generic orlistat 120mg (£32.99 for 84 capsules, £29.69 with EDM10) and branded Xenical 120mg (£42.99 for 84 capsules, £38.69 with EDM10) work through identical mechanisms - the clinical effect is the same regardless of whether you choose generic or branded.
How the Mechanism Affects Your Daily Routine
Because orlistat blocks fat absorption rather than suppressing appetite, you take one 120mg capsule with each main meal containing fat - up to three times daily. If you skip a meal or eat a fat-free meal, you can skip the capsule since there's no fat for the mechanism to target. This targeted approach means orlistat only works when needed, and the effect is directly proportional to the fat content of your meals. Lower-fat meals result in fewer gastrointestinal side effects because there's less unabsorbed fat passing through your system.
Mechanism Comparison: Generic vs Branded vs Lower Strength
All orlistat products work through the same lipase inhibition mechanism, but at different strengths. Orlistat 120mg and Xenical 120mg contain identical active ingredients and block the same proportion of dietary fat. Alli 60mg contains half the dose, so blocks a smaller proportion of fat absorption. For maximum fat-blocking effect, prescription-strength 120mg products are clinically superior to 60mg alternatives. Our 12-week supply options offer the best value: generic orlistat £95.99 (£86.39 with EDM10) versus Xenical £128.99 (£116.09 with EDM10).
