Why The Mechanism Matters For Your Purchase Decision
How Orlistat Actually Works In Your Body
Orlistat works through a precise mechanism called lipase inhibition. When you eat fat-containing foods, your digestive system produces enzymes called lipases that break down dietary fat so it can be absorbed. Orlistat blocks these lipase enzymes, preventing approximately one third of the fat you consume from being digested and absorbed into your bloodstream. This unabsorbed fat passes naturally through your digestive system and is eliminated from your body.
Why "Approximately One Third" Makes Orlistat Effective
The specific mechanism of blocking approximately one third of dietary fat creates a meaningful calorie reduction without completely eliminating fat absorption. This targeted approach means your body still absorbs essential fatty acids and fat-soluble vitamins from the remaining two thirds of fat consumed. A typical meal containing 15g of fat would have approximately 5g blocked by orlistat, reducing caloric intake by roughly 45 calories per meal - potentially 135 calories daily when taken with three main meals.
Orlistat vs Xenical: Identical Mechanisms, Different Prices
Both generic orlistat 120mg and branded Xenical 120mg contain exactly the same active ingredient at identical doses. The fat-blocking mechanism works identically in both products. Generic orlistat 4-week supply costs £29.69 with EDM10, while Xenical costs £38.69 - a monthly saving of £9 for the same clinical effect. Many patients choose generic orlistat for better value, whilst others prefer the Xenical brand. Your prescriber can discuss which option best suits your needs during your online clinical assessment.
Alli 60mg: Lower Dose, Reduced Fat Blocking
Alli contains half the orlistat dose (60mg vs 120mg) which blocks a smaller proportion of dietary fat compared to prescription-strength orlistat. This lower-strength option typically produces milder gastrointestinal effects but provides less fat-blocking capability. For maximum fat-blocking effect, prescription-strength orlistat 120mg or Xenical 120mg offers the full therapeutic dose that blocks approximately one third of dietary fat absorption.
Why Understanding The Mechanism Helps You Succeed
Knowing exactly how orlistat works in your gut helps you optimise your treatment. The medication only blocks fat - not carbohydrates, protein, or alcohol calories. Keeping meals to approximately 15g fat each minimises side effects whilst allowing orlistat to work effectively. Higher fat meals increase both the fat-blocking effect and likelihood of gastrointestinal side effects, as more unabsorbed fat passes through your system.
