The Science Behind Orlistat - Why It Works
How Orlistat 120mg Blocks Fat Absorption
Orlistat works through a precise mechanism called lipase inhibition. When you take a 120mg capsule with meals, orlistat targets lipase enzymes in your digestive system. These enzymes normally break down dietary fat so it can be absorbed into your body. Orlistat blocks approximately one third of these lipase enzymes, preventing roughly one third of the fat you eat from being digested and absorbed. This unabsorbed fat passes naturally through your body, reducing the calories available for storage as body fat.
Why "Approximately One Third" Matters
Orlistat's clinical effectiveness comes from blocking approximately one third of dietary fat - not all fat. This partial inhibition means your body still absorbs essential fatty acids whilst reducing overall calorie intake from fat. The remaining two thirds of fat is processed normally, maintaining nutritional balance. This proven mechanism explains why orlistat requires a reduced-calorie, lower-fat diet to work effectively. Generic orlistat 120mg delivers this same fat-blocking action for £29.69 per month with EDM10, while Xenical costs £38.69 - both containing identical 120mg orlistat doses.
Local Action in Your Digestive System
Unlike appetite suppressants that affect your brain, orlistat works locally in your gut. The medication acts directly on lipase enzymes at the site where fat digestion occurs. Minimal orlistat enters your bloodstream, with most of the active ingredient remaining in your digestive tract where it's needed. This targeted mechanism explains why orlistat's main side effects are gastrointestinal, particularly when eating high-fat meals. Understanding this helps you minimise side effects by keeping meals low in fat whilst maximising weight loss benefits.
Proven Clinical Mechanism Across All Formats
Whether you choose generic orlistat 120mg, branded Xenical 120mg, or lower-strength Alli 60mg, the mechanism remains identical - lipase inhibition leading to reduced fat absorption. The 120mg prescription strength blocks approximately one third of dietary fat, while Alli's 60mg dose blocks a smaller proportion. Our 12-week orlistat supply costs £86.39 with EDM10 (£95.99 without), providing three months of proven fat-blocking action. Xenical 12-week supply costs £116.09 with EDM10 - same mechanism, premium branding.
