Why the Mechanism Matters for Your Purchase Decision

How Orlistat's Fat-Blocking Mechanism Works

Orlistat works by inhibiting lipase enzymes in your digestive system that normally break down dietary fat. When these enzymes are blocked, approximately one third of the fat you consume cannot be digested or absorbed into your body. This unabsorbed fat passes naturally through your digestive system and is excreted. The mechanism is completely local to your gut — orlistat is not absorbed into your bloodstream in significant amounts, which explains its targeted action.

Orlistat vs Xenical: Identical Mechanism, Different Price

Both generic orlistat 120mg and Xenical 120mg work through exactly the same mechanism. They contain identical amounts of the same active ingredient and block approximately one third of dietary fat absorption in precisely the same way. At EverydayMeds, you can choose generic orlistat 120mg for £63.99 (8-week supply) or pay £86.99 for branded Xenical — that's £23 more for the same clinical effect. Use code EDM10 for 10% off either option.

Why This Mechanism Makes Orlistat Effective

The fat-blocking action of orlistat provides a measurable reduction in calorie absorption from dietary fat. Since fat contains 9 calories per gram — more than double that of protein or carbohydrates — blocking approximately one third of fat absorption can significantly reduce your total calorie intake when combined with a reduced-calorie, lower-fat diet. This mechanism supports sustainable weight management by helping create the calorie deficit needed for weight loss.

Understanding the Science Behind Your Purchase

When you buy orlistat or Xenical from EverydayMeds, you're investing in a clinically proven mechanism that's been extensively studied. The lipase inhibition occurs within 1-2 hours of taking each capsule with meals, and the effect lasts throughout the digestion of that meal. Taking one 120mg capsule three times daily with fat-containing meals ensures consistent fat-blocking action throughout your day.

Alli 60mg: Lower-Dose Alternative Mechanism

Alli contains 60mg orlistat — half the prescription strength. It works through the same lipase inhibition mechanism but blocks a smaller proportion of dietary fat. At £49.49 for 84 capsules (8-week supply) with code EDM10, Alli provides a lower-strength option for those preferring a gentler introduction to fat-blocking therapy.
