How Orlistat Blocks Fat Absorption

Orlistat works through a targeted mechanism in your digestive system. It inhibits pancreatic and gastric lipase enzymes responsible for breaking down dietary fats. 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 excreted.

This proven mechanism means orlistat can support weight management when used alongside a reduced-calorie, lower-fat diet. The more you understand how it works, the better you can use it effectively. Order orlistat 120mg from £29.69 (4-week supply with EDM10) today.

Why the Mechanism Matters for Weight Loss

Understanding orlistat's mechanism helps explain why it may support your weight management goals. By blocking approximately one third of dietary fat absorption, orlistat can help reduce your calorie intake from fat. Since fat contains 9 calories per gram (compared to 4 calories per gram for carbohydrates and protein), this reduction can contribute meaningfully to creating a calorie deficit necessary for weight loss.

The mechanism works best when combined with a lower-fat diet. Keeping meals to approximately 15g fat helps minimise gastrointestinal side effects while maximising the weight management benefits. Choose from orlistat 120mg (generic), Xenical 120mg (branded), or Alli 60mg depending on your preference.

Orlistat vs Xenical: Same Mechanism, Different Prices

Both orlistat 120mg and Xenical 120mg work through identical mechanisms - they contain the same active ingredient at the same dose. The fat-blocking effect is clinically equivalent. The key difference is cost: generic orlistat 120mg costs £32.99 for a 4-week supply (£29.69 with EDM10), while branded Xenical costs £42.99 (£38.69 with EDM10). Both require the same online clinical assessment and work through the same proven mechanism.

Alli 60mg uses the same mechanism but at half the dose, blocking a smaller proportion of dietary fat. This lower-strength option may suit those preferring a gentler starting point.

How Long Does the Mechanism Take to Work?

Orlistat's fat-blocking mechanism begins working with your first dose. The medicine acts locally in your gut during each meal containing fat. You may notice gastrointestinal effects (a sign the mechanism is working) within 24-48 hours of starting treatment, particularly if you eat higher-fat meals.

For weight management results, the mechanism works cumulatively over weeks and months when combined with a reduced-calorie, lower-fat diet and increased physical activity. The fat-blocking effect provides ongoing support for your weight management efforts.
