The Science Behind Why Orlistat Works for Weight Loss
How Orlistat's Fat-Blocking Mechanism Works
Orlistat works through a scientifically proven mechanism that targets lipase enzymes in your digestive system. These enzymes normally break down dietary fat so it can be absorbed into your body. Orlistat inhibits approximately one third of these lipases, preventing them from doing their job. The result? Around one third of the fat you eat cannot be digested and passes naturally through your system unabsorbed.
This mechanism occurs locally in your gut - orlistat isn't significantly absorbed into your bloodstream, making it different from appetite suppressants that work on your brain. The unabsorbed fat is eliminated naturally, reducing your calorie intake from dietary sources.
Why This Mechanism Proves Orlistat Works
The fat-blocking action provides tangible evidence that orlistat is working. When you eat a meal containing fat while taking orlistat, you may notice oily stools or increased bowel movements - this is the unabsorbed fat being eliminated. While these gastrointestinal effects can be managed by keeping meals low in fat (around 15g per meal), they actually demonstrate the medication is blocking fat absorption as intended.
Clinical studies consistently show this mechanism supports weight loss when combined with a reduced-calorie, lower-fat diet. The key is understanding that orlistat doesn't work alone - it supports your dietary efforts by reducing fat absorption.
Orlistat 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 fat-blocking effect is clinically equivalent, but the price difference is significant. At EverydayMeds, generic orlistat costs £29.69 for 4 weeks (84 capsules) with code EDM10, while Xenical costs £38.69 - saving you nearly £9 monthly.
For longer treatment periods, the savings increase substantially. Our 12-week supply of generic orlistat costs £86.39 with EDM10, compared to £116.09 for Xenical - that's £29.70 saved for the same clinical effect.
Alli 60mg: Lower-Dose Option
Alli contains orlistat at half the prescription strength (60mg vs 120mg), working through the same fat-blocking mechanism but at reduced intensity. This means it blocks a smaller proportion of dietary fat compared to prescription-strength orlistat. Alli costs £26.09 for 4 weeks with EDM10, making it an accessible option for those preferring to start with lower-dose treatment.

Maximising Orlistat's Fat-Blocking Effect
To optimise how orlistat works, take one capsule with each main meal containing fat - up to three times daily. The medication works best when your daily fat intake doesn't exceed 30% of total calories, spread evenly across meals. This approach maximises the fat-blocking benefit while minimising gastrointestinal side effects.
Now you understand exactly how orlistat's proven mechanism blocks approximately one third of dietary fat absorption, supporting your weight management goals. Ready to start treatment? Use code EDM10 for 10% off your first order, with fast delivery across the UK.
