Why Understanding How Orlistat Works Matters
The Science Behind Orlistat's Fat-Blocking Action
Orlistat works through a targeted mechanism that inhibits lipase enzymes in your digestive system. These enzymes normally break down dietary fat so it can be absorbed into your bloodstream. 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 digestive system and is eliminated from your body.
This mechanism occurs locally in your gut - orlistat is not absorbed into your bloodstream in significant amounts, which means it acts directly where fat digestion happens. The remaining two thirds of dietary fat is still processed normally, which is why orlistat must be used alongside a reduced-calorie, lower-fat diet for optimal results.
Why This Mechanism Makes Orlistat Effective
Understanding that orlistat blocks approximately one third of dietary fat helps explain its effectiveness in clinical studies. By reducing fat absorption, it decreases the total calories your body receives from meals containing fat. This calorie reduction, combined with a structured lower-fat diet, supports weight management goals.
The mechanism also explains why keeping meals low in fat (around 15g per meal) helps minimise gastrointestinal side effects. When you eat high-fat meals, more unabsorbed fat passes through your system, potentially causing oily stools or urgent bowel movements.
Orlistat 120mg vs Xenical: Same Mechanism, Different Prices
Both generic orlistat 120mg and branded Xenical 120mg work through identical mechanisms - they contain the same active ingredient at the same dose. The clinical effect is equivalent, with the main difference being cost. Generic orlistat offers 4-week supplies from £32.99 (£29.69 with EDM10), while Xenical costs £42.99 (£38.69 with EDM10).
For longer-term treatment, generic orlistat 12-week supplies cost £95.99 (£86.39 with EDM10) compared to Xenical at £128.99 (£116.09 with EDM10). Both options provide the same fat-blocking mechanism and require the same online clinical assessment process.
Alli 60mg: Half-Strength Alternative
Alli 60mg contains half the dose of prescription-strength orlistat, working through the same lipase inhibition mechanism but blocking a smaller proportion of dietary fat. This lower-strength option costs £54.99 for 8 weeks (£49.49 with EDM10) and may be suitable for those preferring a gentler starting approach.
