Orlistat, the active ingredient in both generic orlistat 120mg and branded Xenical, blocks approximately one third of dietary fat absorption in your gut. This proven mechanism supports weight management when combined with a reduced-calorie, lower-fat diet. Generic orlistat costs from £29.69 per month with code EDM10, while branded Xenical starts at £38.69 monthly.

Why Orlistat's Mechanism Makes It Worth Buying

How Orlistat's Fat-Blocking Action Works

Orlistat works by inhibiting lipase enzymes in your digestive system. These enzymes are responsible for breaking down dietary fat so it can be absorbed into your body. When orlistat blocks these enzymes, approximately one third of the fat you eat cannot be digested or absorbed. This unabsorbed fat passes naturally through your body, reducing the calories you absorb from fatty foods.

Why This Mechanism Proves Orlistat Works

Unlike appetite suppressants that affect your brain, orlistat works directly where fat absorption happens - in your gut. This targeted action means you can actually see the medication working through changes in your bowel movements when fat isn't absorbed. This visible proof demonstrates orlistat is actively blocking fat absorption, giving you confidence the medication is working as intended.

Generic Orlistat vs Branded Xenical: Same Active Ingredient

Both generic orlistat 120mg and branded Xenical contain identical amounts of the same active ingredient. The fat-blocking mechanism works identically in both products. Generic orlistat offers the same clinical effect at £29.69 per month (4-week supply with EDM10), while Xenical costs £38.69 monthly. Many patients choose generic orlistat for the cost savings without compromising on effectiveness.

Maximising Fat Absorption Benefits

Orlistat works best when you keep meals low in fat - approximately 15g fat per meal. This strategy maximises weight loss benefits while minimising gastrointestinal side effects. High-fat meals result in more unabsorbed fat, leading to oily stools and urgency. By understanding how the mechanism works, you can optimise your diet to get the best results from treatment.
