Why Orlistat's Mechanism Makes It an Effective Choice
The Science Behind Orlistat's Fat-Blocking Action
Orlistat works through a targeted mechanism that inhibits lipase enzymes in your digestive system. These enzymes normally break down dietary fat for absorption, but orlistat blocks approximately one third of this process. The unabsorbed fat passes naturally through your body, reducing calorie intake from fat sources. This proven mechanism has made orlistat a trusted choice since its approval for weight management in adults with BMI 30+ or BMI 28+ with weight-related health conditions.
Why "Approximately One Third" Matters
Understanding that orlistat blocks approximately one third - not all dietary fat - helps set realistic expectations. This partial blocking means you still absorb essential fatty acids whilst reducing overall fat calories. The mechanism works best when combined with a reduced-calorie, lower-fat diet, typically limiting meals to around 15g fat each. This approach minimises gastrointestinal side effects whilst maximising the weight management benefits.
Orlistat 120mg: Generic Excellence from £15.20
Our generic orlistat 120mg delivers the same lipase-inhibiting mechanism as branded versions at exceptional value. A 2-week supply (42 capsules) costs £16.89, reduced to £15.20 with code EDM10. For sustained weight management, our 12-week supply (252 capsules) offers excellent value at £95.99, just £86.39 with EDM10. Each capsule contains 120mg orlistat for maximum fat-blocking effectiveness.
Xenical 120mg: The Original Branded Formula
Xenical contains identical 120mg orlistat with the same one-third fat-blocking mechanism. Some patients prefer Roche's original branded version, available from £21.50 for 2 weeks (£19.35 with EDM10). The clinical effect matches generic orlistat exactly - the key difference is cost. Our 4-week Xenical supply costs £42.99, reduced to £38.69 with EDM10 versus generic orlistat at £29.69.
Alli 60mg: Lower-Strength Option
Alli provides half the orlistat dose at 60mg per capsule, blocking a smaller proportion of dietary fat. This lower strength may suit those preferring gentler introduction to orlistat treatment. A 4-week supply costs £28.99, reduced to £26.09 with EDM10. The same fat-blocking mechanism applies, just at reduced intensity.
How Our Online Prescription Process Works
Understanding orlistat's mechanism helps you make informed treatment decisions. Complete our online health questionnaire for review by UK-licensed prescribers who assess suitability based on your BMI, health conditions, and medical history. If appropriate, your prescription is dispensed by our GPhC-registered Leicester pharmacy with next day delivery. The process typically takes 24-48 hours from assessment to delivery.
Maximising Orlistat's Fat-Blocking Benefits
Since orlistat blocks approximately one third of dietary fat, spreading your daily fat intake across three main meals optimises effectiveness. Taking one capsule with each fat-containing meal ensures consistent lipase inhibition. Remember that high-fat meals increase gastrointestinal side effects - keeping meals around 15g fat each maximises benefits whilst minimising discomfort.
