Why Understanding Orlistat's Mechanism Matters for Your Purchase
The Science Behind Orlistat's Fat-Blocking Action
Orlistat works through a targeted mechanism that inhibits lipase enzymes in your digestive system. These enzymes are responsible for breaking down dietary fat so it can be absorbed. When orlistat blocks these enzymes, approximately one third of the fat you consume passes through your body unabsorbed and is eliminated naturally. This proven mechanism makes orlistat different from appetite suppressants that affect your brain - instead, it works locally in your gut where fat digestion occurs.
Alli 60mg vs Prescription Strength: Choose Your Starting Point
Alli orlistat 60mg provides half the dose of prescription-strength orlistat 120mg, making it suitable for those preferring a lower-strength option. At £28.99 for 4 weeks (£26.09 with EDM10), Alli offers an accessible entry point. For stronger fat-blocking action, our prescription orlistat 120mg costs £32.99 for 4 weeks (£29.69 with EDM10), requiring online clinical assessment. Both products use the same proven mechanism - the difference lies in potency and the amount of fat blocked.
What Happens When You Take Orlistat
When you take orlistat with a meal containing fat, the medication immediately begins inhibiting lipase enzymes in your digestive tract. The fat that cannot be broken down passes through your system unchanged, reducing calorie absorption from dietary fat. This process is most effective when combined with a reduced-calorie, lower-fat diet containing approximately 15g fat per meal. Higher fat meals increase the likelihood of gastrointestinal effects as more unabsorbed fat passes through your system.
Proven Results Through Clinical Mechanism
The fat-blocking mechanism of orlistat has been extensively studied, demonstrating consistent fat absorption reduction of approximately one third across clinical trials. This measurable, predictable action gives you confidence in how the medication works. Unlike treatments that rely on behaviour modification alone, orlistat's physical mechanism provides tangible support for your weight management efforts when used alongside dietary changes.
