Why Understanding Orlistat's Mechanism Matters
How Orlistat Blocks Fat Absorption
Orlistat works through a scientifically proven mechanism that targets lipase enzymes in your digestive system. These enzymes normally break down dietary fat so your body can absorb it. Orlistat inhibits approximately one third of these enzymes, preventing that proportion of fat from being digested and absorbed. The unabsorbed fat passes naturally through your body and is excreted.
Why This Mechanism Works for Weight Management
This targeted fat-blocking action reduces the calories absorbed from dietary fat without affecting protein, carbohydrates, or other nutrients. Since fat contains 9 calories per gram - more than twice that of protein or carbohydrates - blocking approximately one third of fat absorption can significantly reduce overall calorie intake when combined with a reduced-calorie, lower-fat diet.
Choose Your Orlistat Option
Generic orlistat 120mg offers the most cost-effective option at £32.99 for 4 weeks (£29.69 with EDM10). Branded Xenical 120mg provides the same mechanism at £42.99 for 4 weeks (£38.69 with EDM10). For those preferring a gentler approach, Alli 60mg at half-strength costs £28.99 for 4 weeks (£26.09 with EDM10). All require clinical assessment by our UK-licensed prescribers.
Maximising Orlistat's Fat-Blocking Effect
The mechanism works best when meals contain moderate fat levels - approximately 15g fat per meal. Higher fat meals don't increase effectiveness but do increase gastrointestinal side effects as more unabsorbed fat passes through your system. This natural feedback encourages adherence to a lower-fat diet, supporting long-term weight management success.
Clinical Evidence Behind the Mechanism
Orlistat's lipase inhibition mechanism has been extensively studied and proven effective in clinical trials. The medication works regardless of meal timing, but should be taken with each main meal containing fat - up to three times daily. If you skip a meal or eat a fat-free meal, you can skip that dose since there's no dietary fat to block.
