Why Orlistat's Mechanism Makes It Effective

How Orlistat Works in Your Body

Orlistat works by inhibiting lipase enzymes in your digestive system that break down dietary fat. When these enzymes are blocked, approximately one third of the fat you eat cannot be digested or absorbed into your body. This unabsorbed fat passes naturally through your digestive system and is eliminated, reducing the calories stored as body fat.

Proof That Orlistat Works

The mechanism itself demonstrates orlistat's effectiveness. Unlike appetite suppressants that act on the brain, orlistat works locally in your gut where fat digestion occurs. You may notice oily stools or fatty discharge - while unpleasant, these are actually signs the medicine is working by blocking fat absorption. Generic orlistat 120mg costs just £29.69 for 4 weeks with EDM10, making it cost-effective for proven fat-blocking action.

Three Orlistat Options Available

Understanding how orlistat works helps you choose the right option. Generic orlistat 120mg (£15.20 for 2 weeks with EDM10) provides maximum fat-blocking at the lowest cost. Xenical 120mg (£19.35 for 2 weeks with EDM10) contains identical orlistat but as the original branded version. Alli 60mg (£26.09 for 4 weeks with EDM10) offers half-strength dosing for those preferring gentler effects.

Why Fat Blocking Works for Weight Loss

Each gram of fat contains 9 calories - more than double that of carbohydrates or protein. By blocking approximately one third of dietary fat absorption, orlistat significantly reduces calorie intake without requiring dramatic diet changes. Combined with a reduced-calorie, lower-fat diet, this mechanism supports sustainable weight management. The remaining two thirds of fat is still absorbed normally, ensuring your body gets essential fatty acids.

Maximising Orlistat's Fat-Blocking Effect

Understanding the mechanism helps optimise results. Keep meals to approximately 15g fat each to minimise side effects while maximising benefits. Take one 120mg capsule with each main meal containing fat - skip doses if meals are fat-free. The 12-week supply (252 capsules) costs £86.39 with EDM10, providing excellent value for sustained fat-blocking action.
