How Orlistat's Fat-Blocking Mechanism Supports Weight Loss
The Science: How Orlistat Blocks Fat Absorption
Orlistat works by inhibiting lipase enzymes in your digestive system that normally break down dietary fat. When these enzymes are blocked, approximately one third of the fat you eat cannot be digested or absorbed into your body. This unabsorbed fat passes naturally through your system, reducing the calories your body stores. Both generic orlistat 120mg and branded Xenical 120mg use this identical mechanism at the same dose.
Why This Mechanism Proves Orlistat Works
Unlike appetite suppressants that work on brain chemistry, orlistat's fat-blocking action is direct and measurable. You may notice the unabsorbed fat in your stools - this visible proof shows the medication is actively preventing fat absorption. Clinical studies demonstrate this mechanism can support meaningful weight loss when combined with a reduced-calorie, lower-fat diet containing approximately 30% of calories from fat.
Generic Orlistat vs Xenical: Same Mechanism, Better Value
Generic orlistat 120mg delivers the identical fat-blocking mechanism as branded Xenical at significantly lower cost. A 4-week supply of generic orlistat costs £29.69 with EDM10 versus £38.69 for Xenical - saving you £108 annually while achieving the same clinical effect. Both products block approximately one third of dietary fat absorption with identical dosing: one capsule with each main meal containing fat.
Optimising Orlistat's Fat-Blocking Action
To maximise orlistat's mechanism while minimising side effects, keep meals to approximately 15g fat each. Higher fat meals mean more unabsorbed fat passing through your system, increasing gastrointestinal effects. This isn't harmful - it's proof the medication is working - but staying within recommended fat limits makes treatment more comfortable while ensuring optimal fat blocking.
