The Science Behind Orlistat's Fat-Blocking Action
How Orlistat Blocks Fat Absorption
Orlistat works through a proven mechanism that targets lipase enzymes in your digestive system. These enzymes are responsible for breaking down dietary fat so it can be absorbed into your body. When you take orlistat 120mg with a meal, it inhibits these lipases, preventing approximately one third of the fat you eat from being digested and absorbed. This unabsorbed fat passes naturally through your body, reducing your overall calorie intake from dietary fat.
Why This Mechanism Matters for Weight Loss
The fat-blocking action of orlistat provides measurable calorie reduction with each meal. Unlike appetite suppressants that work on the brain, orlistat acts locally in your gut where fat digestion occurs. This targeted approach means you're getting proven fat reduction - approximately one third less fat absorption - without systemic effects throughout your body. Generic orlistat 120mg costs just £29.69 for a 4-week supply with EDM10, making this proven mechanism accessible and affordable.
Orlistat vs Xenical: Same Mechanism, Different Price
Both generic orlistat 120mg and branded Xenical 120mg work through identical fat-blocking mechanisms. The active ingredient and dose are the same, meaning you get the same approximately one third fat absorption reduction with either product. The key difference is cost - generic orlistat 120mg (£29.69 for 4 weeks with EDM10) offers significant savings compared to Xenical 120mg (£38.69 for 4 weeks with EDM10). Both require prescription following clinical assessment by our UK-licensed prescribers.
Alli 60mg: Lower-Dose Fat Blocking
Alli 60mg contains half the dose of prescription-strength orlistat, providing a gentler introduction to fat-blocking treatment. While it blocks a smaller proportion of dietary fat compared to orlistat 120mg, it may be suitable for those preferring to start with lower-strength treatment. Alli 60mg costs £26.09 for a 4-week supply with EDM10 discount code.
Maximising Orlistat's Fat-Blocking Effect
Understanding how orlistat works helps you use it effectively. Take one capsule with each main meal containing fat - the mechanism only works when there's dietary fat present to block. Keeping fat intake to approximately 15g per meal optimises the blocking effect while minimising side effects. The unabsorbed fat that passes through your body is actually proof the mechanism is working as intended.
