Choose Your Orlistat Treatment: Mechanism Proven Effective

How Orlistat's Fat-Blocking Mechanism Works

Orlistat works by inhibiting lipase enzymes in your digestive system, preventing approximately one third of dietary fat from being absorbed. This mechanism operates locally in the gut, not through your bloodstream or brain. When you eat fat-containing meals, orlistat blocks these enzymes, allowing unabsorbed fat to pass naturally through your body. This proven action supports weight management when combined with a reduced-calorie, lower-fat diet and increased physical activity.

Orlistat vs Xenical: Identical Mechanism, Different Pricing

Both generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients with the same fat-blocking mechanism. Our 4-week orlistat supply costs £32.99 (£29.69 with EDM10), whilst equivalent Xenical costs £42.99 (£38.69 with EDM10). The mechanism blocking approximately one third of dietary fat remains identical—the key difference is cost savings of nearly £9 monthly with generic orlistat. Following online clinical assessment, UK-licensed prescribers determine which option suits your needs.

Alli 60mg: Lower-Strength Fat Blocking

Alli contains half the orlistat dose at 60mg, using the same fat-blocking mechanism but with reduced potency. This blocks a smaller proportion of dietary fat compared to prescription-strength 120mg formulations. Our 8-week Alli supply costs £54.99 (£49.49 with EDM10), providing an alternative for those preferring lower-strength treatment. The mechanism remains consistent—lipase enzyme inhibition reducing fat absorption in your digestive system.

Why Understanding the Mechanism Matters for Your Choice

Knowing that orlistat blocks approximately one third of dietary fat through proven lipase inhibition helps you understand why maintaining a lower-fat diet is essential. High-fat meals increase gastrointestinal side effects because more unabsorbed fat passes through your system. Whether choosing orlistat, Xenical, or Alli, this mechanism requires commitment to dietary changes for optimal results. The fat-blocking action occurs with each dose, making consistent use alongside meal planning crucial for weight management success.
