Why Understanding The Mechanism Matters For Your Purchase
How Orlistat's Fat-Blocking Mechanism Actually Works
When you understand exactly how orlistat works, you'll see why it's become the UK's most prescribed weight loss medication. Orlistat acts as a lipase inhibitor - blocking the enzymes in your digestive system that break down dietary fat. This isn't guesswork or placebo effect - it's measurable, visible fat blocking that you can see working. The medication prevents approximately one third of the fat you eat from being digested and absorbed. Instead, this unabsorbed fat passes naturally through your body, reducing your calorie intake from dietary sources.
120mg vs 60mg: Maximum vs Moderate Fat Blocking
The key difference between orlistat 120mg and Alli 60mg isn't just dosage - it's the extent of fat blocking action. At 120mg (prescription strength), orlistat provides maximum lipase inhibition, blocking the highest proportion of dietary fat possible with this medication. Generic orlistat 120mg costs £29.69 for 4 weeks with EDM10, while branded Xenical 120mg costs £38.69 - identical clinical effect, different price points. Alli 60mg at £26.09 for 4 weeks provides moderate fat blocking for those preferring a gentler starting approach. All three contain the same active ingredient working through the same proven mechanism.
Why This Mechanism Proves Clinical Effectiveness
Unlike appetite suppressants that work on brain chemistry with variable results, orlistat's mechanism is direct and measurable. You'll often notice the medication working within days through gastrointestinal effects - this is actually proof the fat blocking is occurring. When you eat a meal containing fat, orlistat prevents approximately one third from absorption. The unabsorbed fat must go somewhere - it passes through your digestive system, often creating oily stools or urgent bowel movements. While initially inconvenient, these effects confirm the medication is actively blocking dietary fat as intended.
Maximising Fat Blocking Through Smart Dosing
Understanding the mechanism helps you use orlistat more effectively. Take one capsule with each main meal containing fat - if a meal contains no fat, skip that dose as there's nothing to block. The 8-week supply (168 capsules) at £57.59 with EDM10 provides excellent value for establishing consistent fat blocking over two months. By keeping meals under 15g fat each, you minimise side effects while maintaining the medication's fat-blocking action. The mechanism works best with consistent dosing - three times daily with fat-containing meals.
