The Science Behind Orlistat - Why It Works
How Orlistat Blocks Fat Absorption
Orlistat works by inhibiting lipase enzymes in your digestive system. These enzymes normally break down dietary fat so it can be absorbed into your bloodstream. When orlistat blocks these enzymes, approximately one third of the fat you eat cannot be digested or absorbed. Instead, this unabsorbed fat passes naturally through your body and is eliminated. This mechanism is identical whether you choose generic orlistat 120mg (£15.20 for 2 weeks with EDM10), branded Xenical 120mg, or lower-strength Alli 60mg.
Why The Mechanism Matters For Weight Loss
Each gram of fat contains 9 calories. By blocking approximately one third of dietary fat absorption, orlistat can significantly reduce calorie intake when used alongside a reduced-calorie, lower-fat diet. The medication acts locally in your gut rather than affecting your brain or nervous system like other weight loss treatments. This targeted approach means you're getting proven fat-blocking action with a well-understood mechanism. Order your 4-week supply of orlistat today from £29.69 with code EDM10.
Orlistat vs Wegovy - Different Mechanisms
While both support weight management, orlistat and Wegovy work through completely different mechanisms. Orlistat blocks fat absorption in the gut, while Wegovy affects appetite regulation through GLP-1 receptor activation. Orlistat's lipase inhibition is immediate - it works with every meal containing fat. The mechanism is straightforward: take one 120mg capsule with each main meal, and approximately one third of dietary fat in that meal won't be absorbed. This proven approach has helped patients for over two decades.
Clinical Evidence Behind The Mechanism
Orlistat's mechanism has been extensively studied in clinical trials. The lipase inhibition effect is dose-dependent and consistent. At 120mg strength (available as generic orlistat from £32.99 for 4 weeks, or Xenical from £42.99), approximately one third of dietary fat is blocked. The lower-dose Alli 60mg blocks a smaller proportion. The unabsorbed fat provides visible evidence the mechanism is working - though this can cause gastrointestinal effects if you eat high-fat meals. Keeping meals low in fat (around 15g per meal) maximises weight loss while minimising side effects.
