Why Understanding Orlistat's Mechanism Matters For Your Purchase
How Orlistat Blocks Fat Absorption - The Science
Orlistat works through a targeted mechanism that blocks approximately one third of dietary fat from being absorbed in your digestive system. Unlike appetite suppressants that affect your brain, orlistat acts locally in your gut by inhibiting pancreatic and gastric lipase enzymes. These enzymes normally break down dietary fats into smaller molecules that can be absorbed. When orlistat blocks these enzymes, approximately one third of the fat you consume cannot be digested or absorbed, passing naturally through your body instead.
Three Products, Same Proven Fat-Blocking Mechanism
Whether you choose generic orlistat 120mg (from £29.69 for 4 weeks with EDM10), branded Xenical 120mg (from £38.69 for 4 weeks with EDM10), or lower-dose Alli 60mg (from £49.49 for 8 weeks with EDM10), all work through identical lipase inhibition. The 120mg prescription strength provides maximum fat-blocking effect, whilst Alli's 60mg offers a gentler introduction. Generic orlistat delivers the same clinical effect as Xenical at significant savings - often £9+ per month less.
Why This Mechanism Proves Orlistat Works
Orlistat's fat-blocking mechanism provides visible evidence it's working. The unabsorbed fat that passes through your system serves as proof that approximately one third of dietary fat is being blocked from absorption. This means fewer calories from fat enter your body, supporting weight management when combined with a reduced-calorie, lower-fat diet. Unlike treatments with invisible effects, you can literally see orlistat working.
Optimising Results Through Understanding
Understanding orlistat's metabolism helps maximise results whilst minimising side effects. Since the medication blocks fat absorption, keeping meals to approximately 15g fat each reduces gastrointestinal effects significantly. Take one capsule with each main meal containing fat - if you skip a meal or eat fat-free, skip that dose. This targeted approach means you're only using medication when needed for fat-blocking.
