The Science Behind Orlistat's Fat-Blocking Action
How Orlistat Blocks Fat Absorption
Orlistat works through a scientifically proven mechanism that targets lipase enzymes in your digestive system. These enzymes normally break down dietary fat so your body can absorb it. When you take orlistat with a meal, it inhibits these lipases, preventing approximately one third of the fat you eat from being digested and absorbed. This unabsorbed fat passes naturally through your body, reducing the calories absorbed from your meal.
When to Take Orlistat for Maximum Effect
Take one orlistat 120mg capsule with each main meal that contains fat. You can take it immediately before eating, during your meal, or up to one hour after finishing. If you skip a meal or eat something with no fat content, you can skip that dose. The timing is crucial because orlistat needs to be present in your gut when fat arrives to block its absorption effectively.
Generic Orlistat vs Xenical - Same Mechanism, Different Price
Both generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients and work through exactly the same fat-blocking mechanism. Generic orlistat costs £32.99 for 4 weeks (£29.69 with EDM10), while Xenical costs £42.99 (£38.69 with EDM10). The clinical effect is identical - both block approximately one third of dietary fat absorption. Many patients choose generic orlistat for the cost savings without compromising on effectiveness.
Why the Mechanism Proves It Works
The beauty of orlistat's mechanism is that you can see it working - the gastrointestinal effects are actually proof that fat is being blocked from absorption. When you keep your fat intake low (around 15g per meal), these effects are minimised while the weight management benefits continue. This direct mechanism means orlistat works locally in your gut rather than affecting your brain or other body systems.
