The Proven Mechanism That Delivers Results
How Orlistat Works in Your Body
Orlistat works through a scientifically proven mechanism that targets fat absorption in your digestive system. Unlike appetite suppressants that act on your brain, orlistat works locally in your gut by inhibiting pancreatic lipase enzymes. These enzymes are responsible for breaking down dietary fat into smaller molecules that can be absorbed. When orlistat blocks approximately one third of these enzymes, the corresponding fat cannot be digested or absorbed into your body.
This unabsorbed fat passes naturally through your digestive system and is eliminated from your body. The mechanism is direct and measurable - you're literally reducing the calories your body absorbs from dietary fat. This is why understanding how orlistat works gives confidence in choosing it for weight management.
Why the Mechanism Proves Effectiveness
The lipase inhibition mechanism explains why orlistat has consistent clinical results. Every time you take a capsule with a fat-containing meal, orlistat is actively working to block approximately one third of that fat from being absorbed. This isn't dependent on willpower or complex metabolic processes - it's a direct pharmaceutical action in your digestive tract.
Generic orlistat 120mg provides this proven mechanism from just £29.69 for a 4-week supply (84 capsules) with code EDM10. Branded Xenical 120mg offers identical lipase inhibition at £38.69 for the same supply. Both require prescription following clinical assessment by our UK-licensed prescribers.
Orlistat vs Alli: Understanding the Dosage Difference
The mechanism remains the same whether you choose prescription-strength orlistat 120mg or lower-strength Alli 60mg. However, the extent of lipase inhibition differs with dosage. Prescription orlistat 120mg blocks approximately one third of dietary fat absorption, while Alli 60mg at half the dose provides proportionally less fat blocking.
This is why many people progress from Alli 60mg (£49.49 for 8 weeks with EDM10) to prescription-strength orlistat 120mg (£57.59 for 8 weeks with EDM10) when they want maximum lipase inhibition for enhanced weight management results.
What Happens to the Blocked Fat
Understanding what happens to blocked fat helps explain orlistat's side effect profile and why dietary adherence matters. The approximately one third of dietary fat that orlistat prevents from being absorbed doesn't disappear - it passes through your digestive system unchanged. This can cause gastrointestinal side effects, particularly if you consume high-fat meals.
The key insight is that side effects are actually evidence the mechanism is working. When patients experience oily stools or anal leakage, it demonstrates that orlistat is successfully blocking fat absorption. Keeping meals low in fat (approximately 15g per meal) minimises these effects while maintaining the weight loss benefits.
