How Orlistat's Fat-Blocking Mechanism Drives Results

The Science Behind Orlistat's Weight Loss Mechanism

Orlistat works through a targeted mechanism that directly blocks fat absorption in your digestive system. Unlike stimulants that affect your brain, orlistat acts locally in your gut by inhibiting lipase enzymes responsible for breaking down dietary fat. This proven mechanism prevents approximately one third of the fat you eat from being digested and absorbed into your body. The unabsorbed fat passes naturally through your digestive system, reducing your calorie intake from dietary fat.

Why This Mechanism Makes Orlistat Effective

The fat-blocking mechanism provides measurable, science-based weight loss support. When you take orlistat 120mg with each main meal, you're blocking approximately one third of dietary fat calories - that's roughly 9 calories per gram of fat prevented from absorption. Generic orlistat 120mg delivers this full-strength mechanism for just £29.69 per 4-week supply with code EDM10, while Xenical offers the identical mechanism at £38.69. This mechanism works best alongside a reduced-calorie, lower-fat diet where you limit fat intake to approximately 15g per meal.

Alli vs Prescription Orlistat - How the Mechanisms Compare

Alli 60mg contains half the dose of prescription-strength orlistat, delivering a milder version of the same fat-blocking mechanism. While prescription orlistat 120mg blocks approximately one third of dietary fat, Alli 60mg blocks a smaller proportion. For maximum mechanism effectiveness, prescription orlistat 120mg starting from £15.20 per 2-week supply offers superior fat-blocking action. Alli 60mg at £26.09 per 4-week supply suits those preferring a gentler starting approach. Both work through identical mechanisms - the difference is potency.
