The Science Behind Orlistat's Fat-Blocking Action
How Orlistat Blocks Fat Absorption
Orlistat works through a targeted mechanism that inhibits pancreatic and gastric lipases - the enzymes responsible for breaking down dietary fats in your digestive system. When you take orlistat with a meal containing fat, it binds to these lipase enzymes and blocks approximately one third of the fat from being digested and absorbed. This unabsorbed fat passes naturally through your body, reducing the calories you absorb from dietary fat.
Why This Mechanism Proves Orlistat Works
Unlike appetite suppressants that work on brain chemistry, orlistat's mechanism is direct and measurable. You can actually see evidence of unabsorbed fat being eliminated from your body. This visible proof demonstrates the medication is actively blocking fat absorption. The mechanism has been extensively studied in clinical trials, showing consistent fat-blocking activity when used alongside a reduced-calorie, lower-fat diet.
Generic Orlistat vs Xenical - Same Proven Mechanism
Both generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients and work through the same fat-blocking mechanism. Generic orlistat costs just £29.69 for a 4-week supply with code EDM10, compared to £38.69 for Xenical. The clinical effect is identical - both block approximately one third of dietary fat absorption. Choose generic orlistat for maximum value or Xenical if you prefer the branded option.
Optimising Orlistat's Fat-Blocking Effect
To maximise orlistat's mechanism, keep each meal to approximately 15g of fat or less. Higher-fat meals increase side effects but don't improve the fat-blocking effect - orlistat still blocks approximately one third regardless. Take one 120mg capsule with each main meal containing fat, up to three times daily. This consistent dosing ensures optimal lipase inhibition throughout your day.
