The Science Behind Fat Blocking - Ready to Buy?
How Orlistat's Fat-Blocking Mechanism Works
Orlistat works through a scientifically proven mechanism that targets lipase enzymes in your digestive system. These enzymes normally break down dietary fats so your body can absorb them. Orlistat inhibits approximately one third of these lipases, preventing roughly 30% of the fat you eat from being digested and absorbed. This unabsorbed fat passes naturally through your body, effectively reducing your calorie intake from dietary fats.
This mechanism works locally in your gut - orlistat isn't absorbed into your bloodstream in significant amounts. Unlike appetite suppressants that affect your brain, orlistat's fat-blocking action happens exactly where dietary fat is processed. Generic orlistat 120mg costs from £29.69 (4 weeks) whilst branded Xenical offers the identical mechanism for £38.69 (4 weeks) with EDM10.
Why the Mechanism Proves Orlistat Works
The beauty of orlistat's mechanism lies in its predictability. When you eat a meal containing 45g of fat, orlistat blocks approximately 15g from absorption - that's 135 fewer calories absorbed per meal. This isn't guesswork or hoping for results; it's measurable fat blocking that happens with every dose you take alongside meals containing fat.
The blocked fat becomes visible proof the mechanism works - patients often notice oily stools or spotting, particularly when eating higher-fat meals. While these effects can be managed by keeping meals low in fat (around 15g per meal), they demonstrate orlistat is actively blocking dietary fat absorption as designed.
Three Proven Options - Same Fat-Blocking Science
All our orlistat products use the same proven mechanism but at different strengths. Prescription orlistat 120mg and branded Xenical 120mg both block approximately one third of dietary fat - the only difference is cost. Generic orlistat offers 8-week supplies from £57.59, whilst Xenical 8-week packs cost £78.29 with code EDM10. Alli 60mg provides the same mechanism at half strength for those preferring a gentler starting approach.
Each option requires the same fat-blocking commitment: taking one capsule with each main meal containing fat, up to three times daily. The mechanism works best alongside a reduced-calorie, lower-fat diet where daily fat intake stays around 30% of total calories.
