Why Orlistat's Mechanism Makes It Effective
How Orlistat Blocks Fat Absorption
Orlistat works through a targeted mechanism in your digestive system. The medication inhibits pancreatic and gastric lipases - enzymes responsible for breaking down dietary fat. When these enzymes are blocked, approximately one third of the fat you consume cannot be digested or absorbed into your body. This unabsorbed fat passes naturally through your digestive system and is eliminated, reducing your calorie intake from dietary fat.
The Science Behind Fat Blocking
Unlike appetite suppressants that work in the brain, orlistat acts locally in your gut. This lipase inhibition means the medication is not significantly absorbed into your bloodstream, targeting fat absorption where it happens. Generic orlistat 120mg provides this proven mechanism from £32.99 for 4 weeks (£29.69 with EDM10), while branded Xenical offers identical clinical effect at £42.99 (£38.69 with EDM10).
Why One Third Fat Blocking Matters
Orlistat blocks approximately one third of dietary fat - not all fat consumed. This means if you eat 30g fat in a meal, roughly 10g is blocked while 20g is still absorbed normally. This mechanism explains why maintaining a lower-fat diet maximises effectiveness and minimises gastrointestinal side effects. The remaining two thirds of fat absorption ensures your body still receives essential fatty acids.
Proving Orlistat Works
The mechanism demonstrates why orlistat can support weight management when used alongside a reduced-calorie, lower-fat diet. Clinical studies show this lipase inhibition approach may help reduce dietary fat calories absorbed into your body. Available as 8-week supplies: orlistat £63.99 (£57.59 with EDM10) or Xenical £86.99 (£78.29 with EDM10) from our GPhC-registered pharmacy.
