Why Three Times Daily Maximises Fat Blocking
How Orlistat's Mechanism Works in Your Digestive System
Orlistat works by inhibiting lipase enzymes in your gut that normally break down dietary fat for absorption. When you take one 120mg capsule with each main meal, orlistat blocks approximately one third of the fat in that meal from being digested and absorbed. The unabsorbed fat passes naturally through your digestive system. This local action in your gut means orlistat isn't absorbed into your bloodstream significantly, making it different from appetite suppressants that work in your brain.
Why the Three Times Daily Dosing Schedule Works
Taking orlistat three times daily with fat-containing meals ensures consistent fat blocking throughout your day. Each 120mg capsule works for that specific meal, so missing doses means missing the fat-blocking benefit. Generic orlistat 120mg at £32.99 for 84 capsules (£29.69 with EDM10) provides 4 weeks of three-times-daily treatment. Xenical 120mg offers identical fat-blocking action at £42.99 for 84 capsules (£38.69 with EDM10).
Clinical Evidence Behind Orlistat's Fat Blocking Action
Clinical studies demonstrate that orlistat consistently blocks approximately one third of dietary fat when taken three times daily with meals. This mechanism has been extensively studied and forms the basis for its MHRA approval in the UK. The fat-blocking action is directly proportional to the fat content of your meals - higher fat meals result in more unabsorbed fat, which explains why maintaining a lower-fat diet minimises gastrointestinal side effects while maximising weight management benefits.
Choosing Between Generic Orlistat and Branded Xenical
Both generic orlistat 120mg and Xenical 120mg contain identical active ingredients and work through the same fat-blocking mechanism. The three-times-daily dosing applies to both products. For longer treatment periods, our 12-week supply of generic orlistat costs £95.99 (£86.39 with EDM10) compared to Xenical at £128.99 (£116.09 with EDM10), offering significant savings while maintaining identical clinical effectiveness.
What to Expect When Orlistat Blocks Fat Absorption
When orlistat successfully blocks approximately one third of dietary fat, you may experience gastrointestinal effects as the unabsorbed fat passes through your system. These effects are actually evidence that the mechanism is working. Lower-fat meals (approximately 15g fat per meal) work optimally with orlistat's three-times-daily schedule, reducing side effects while maintaining effectiveness.
