The Science Behind Orlistat's Weight Loss Effect
How Orlistat Blocks Fat Absorption
Orlistat works by inhibiting lipase enzymes in your digestive system. These enzymes normally break down dietary fat so your body can absorb it. When orlistat blocks approximately one third of these enzymes, that proportion of fat passes through your system unabsorbed. This reduces the calories you absorb from fat-rich foods, supporting weight loss when combined with a reduced-calorie, lower-fat diet.
Why the Mechanism Proves It Works
Unlike appetite suppressants that work in the brain, orlistat's mechanism is measurable and visible. The unabsorbed fat is eliminated naturally, often making treatment effects noticeable. This local action in the gut means orlistat isn't absorbed into your bloodstream significantly, focusing its effect where dietary fat is processed. At EverydayMeds, we stock all three orlistat options: Alli 60mg (£28.99 for 4 weeks), Orlistat 120mg (£32.99 for 4 weeks), and Xenical 120mg (£42.99 for 4 weeks) - all 10% off with EDM10.
Choosing Your Orlistat Strength
Alli 60mg provides a lower-strength introduction to orlistat treatment. Many customers start here to assess tolerance before considering prescription strength. Orlistat 120mg offers the full clinical dose at our most competitive price - £15.20 for 2 weeks with EDM10. Xenical 120mg contains identical active ingredients but as the original branded version. All work through the same fat-blocking mechanism, differing only in strength and cost.
Maximising Results Through Diet
Understanding orlistat's mechanism helps optimise results. Since it blocks approximately one third of dietary fat, keeping meals low in fat (around 15g per meal) minimises side effects whilst maintaining effectiveness. High-fat meals lead to more unabsorbed fat, increasing gastrointestinal effects. Our online consultation includes dietary guidance to help you succeed with treatment.
