The Science Behind Orlistat - Why It Works for You
How Orlistat Blocks Fat Absorption in Your Body
Orlistat works through a scientifically proven mechanism that targets lipase enzymes in your digestive system. These enzymes are responsible for breaking down dietary fat so your body can absorb it. When you take orlistat, it inhibits approximately one third of these lipases, preventing that proportion of fat from being digested and absorbed. This unabsorbed fat passes naturally through your body, reducing the calories available for weight gain.
Unlike stimulant-based treatments that affect your brain, orlistat acts locally in your gut and is not absorbed into your bloodstream in significant amounts. This targeted approach makes it an effective choice for adults with a BMI of 30 or above, or 28 or above with weight-related health conditions.
Why Generic Orlistat and Branded Xenical Work Identically
Both generic orlistat 120mg and branded Xenical 120mg contain exactly the same active ingredient at the same dose. The mechanism of blocking approximately one third of dietary fat absorption is identical between both products. At EverydayMeds, generic orlistat costs from £15.20 for 42 capsules (2-week supply) whilst Xenical costs from £19.35 - both prices include 10% off with code EDM10.
Whether you choose cost-effective generic orlistat or prefer branded Xenical, you're getting the same proven fat-blocking mechanism. Your prescriber will help determine which option suits your needs during your online clinical assessment.
Maximising Results: How Diet Affects Orlistat's Mechanism
Understanding how orlistat works helps you optimise your results. Since it blocks approximately one third of dietary fat, keeping your fat intake moderate (around 15g per meal) minimises gastrointestinal side effects whilst maintaining effectiveness. High-fat meals increase side effects because more unabsorbed fat passes through your system.
The medication works best alongside a reduced-calorie, lower-fat diet and regular physical activity. This isn't just advice - it's essential for the mechanism to support meaningful weight management. A daily multivitamin taken at bedtime helps replace fat-soluble vitamins that may be reduced.
Comparing Orlistat 120mg with Alli 60mg
Alli contains 60mg orlistat - half the prescription dose. Whilst it uses the same fat-blocking mechanism, it's clinically less potent, blocking a smaller proportion of dietary fat compared to prescription-strength products. For maximum effectiveness, prescription orlistat 120mg or Xenical 120mg are recommended following clinical assessment.
