Why Understanding the Mechanism Matters for Your Purchase
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 eliminated. Unlike appetite suppressants that act on the brain, orlistat works locally in your gut and is not significantly absorbed into your bloodstream.
Why This Mechanism Makes Orlistat Effective
The fat-blocking action of orlistat provides a direct way to reduce calorie intake from dietary fat. Since fat contains 9 calories per gram compared to 4 calories per gram from carbohydrates or protein, blocking fat absorption can significantly impact your daily calorie balance. This mechanism works best when combined with a reduced-calorie, lower-fat diet and regular physical activity. At EverydayMeds, orlistat 120mg capsules start from £16.89 for 84 capsules (4 weeks), or just £29.69 with code EDM10.
Prescription Strength vs Lower Dose Options
We stock three orlistat options with different strengths. Orlistat 120mg and Xenical 120mg both contain the same active ingredient at prescription strength, with generic orlistat offering better value at £63.99 for 8 weeks (£57.59 with EDM10) compared to Xenical at £86.99. Alli 60mg provides a lower-strength option at £54.99 for 8 weeks. All products work through the same fat-blocking mechanism, with higher doses blocking more dietary fat absorption.
Timeline for Results Based on the Mechanism
Because orlistat blocks approximately one third of dietary fat with each dose, the weight loss timeline depends on your diet and fat intake. The mechanism begins working immediately with your first dose, but meaningful weight loss typically develops over several weeks of consistent use alongside dietary changes. Most patients see initial results within 2-4 weeks when following a lower-fat diet. For sustained results, 12-week supplies are popular, with our orlistat 252 capsules priced at £95.99 (£86.39 with EDM10).
