Why Orlistat's Fat-Blocking Action Works
The Science Behind Orlistat's Effectiveness
Orlistat works through a clinically-proven mechanism that directly reduces calorie absorption from dietary fat. By inhibiting pancreatic and gastric lipase enzymes, orlistat prevents approximately one third of the fat you eat from being broken down and absorbed. This unabsorbed fat passes naturally through your digestive system, reducing overall calorie intake without affecting your brain chemistry like stimulant-based treatments.
Why Take Orlistat With Food?
Taking orlistat without food serves no purpose because the medication needs dietary fat to work on. Orlistat capsules should be taken immediately before, during, or up to one hour after each fat-containing meal. If you skip a meal or eat something fat-free, you can skip that dose. This targeted approach means orlistat only works when needed, making it safer than systemic weight loss medications.
Comparing Your Options: Generic vs Branded
Both generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients and work through the same fat-blocking mechanism. Generic orlistat offers excellent value at £32.99 for 4 weeks (£29.69 with EDM10), while Xenical costs £42.99 for 4 weeks (£38.69 with EDM10). Alli 60mg provides half the dose at £28.99 for 4 weeks (£26.09 with EDM10). All three products block fat absorption - the difference is strength and cost.
What to Expect When Orlistat Blocks Fat
When orlistat blocks approximately one third of dietary fat, you may experience gastrointestinal effects like oily stools or increased bowel movements. These effects actually confirm the medication is working by preventing fat absorption. Keeping meals low in fat (around 15g per meal) significantly reduces side effects while maintaining effectiveness. Most patients find effects manageable when following a reduced-calorie, lower-fat diet.
