The Proven Mechanism That Drives Results
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 it can be absorbed into your body. When you take orlistat, 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 system.
This mechanism is why Alli 60mg capsules can support weight management when used alongside a reduced-calorie, lower-fat diet. At EverydayMeds, our 8-week Alli supply costs £54.99 (£49.49 with EDM10), giving you two months to experience how this fat-blocking action works.
Why This Mechanism Matters for Weight Loss
Unlike appetite suppressants that work on the brain, orlistat acts locally in your gut without being significantly absorbed into your bloodstream. This targeted action means it directly reduces the calories your body absorbs from dietary fat—typically the most calorie-dense macronutrient at 9 calories per gram.
The beauty of this mechanism is its predictability. Every gram of fat blocked represents saved calories that would otherwise contribute to weight gain or prevent weight loss. Our 4-week Alli supply at £28.99 (£26.09 with EDM10) lets you start experiencing this fat-blocking effect quickly.
Comparing Orlistat Strengths and Their Mechanisms
While Alli 60mg offers a lower-strength option, prescription-strength orlistat 120mg provides enhanced fat-blocking capability. Our generic orlistat 120mg costs £32.99 for 4 weeks (£29.69 with EDM10), while branded Xenical 120mg costs £42.99 (£38.69 with EDM10). Both contain identical active ingredients working through the same proven mechanism.
The higher dose blocks a greater proportion of dietary fat, potentially supporting more significant weight management results when combined with appropriate dietary changes. However, Alli's lower dose may be suitable for those preferring a gentler starting approach.
Maximising the Fat-Blocking Effect
To optimise orlistat's mechanism, distribute your daily fat intake evenly across three main meals, keeping each meal to approximately 15g of fat. This approach minimises gastrointestinal side effects while maximising the weight management benefits. Higher-fat meals can overwhelm the system and cause uncomfortable side effects.
The mechanism works best when you maintain consistency. Our 12-week supplies offer excellent value—orlistat 120mg at £95.99 (£86.39 with EDM10) or Alli at £129.99 (£116.99 with EDM10)—supporting sustained fat-blocking action over three months.
