Understanding Orlistat's Fat-Blocking Mechanism
How Orlistat Blocks Fat Absorption
Orlistat works through a scientifically proven mechanism that targets fat digestion in your gut. The active ingredient inhibits lipase enzymes responsible for breaking down dietary fat, preventing approximately one third of the fat you eat from being digested and absorbed. This unabsorbed fat passes naturally through your digestive system, effectively reducing the calories your body takes in from dietary fat sources.
The Science Behind Fat Blocking
Unlike appetite suppressants that act on the brain, orlistat works locally in your digestive system. When you take an orlistat 120mg capsule with a meal containing fat, it binds to lipase enzymes in your stomach and small intestine. This binding action prevents these enzymes from breaking down approximately one third of dietary triglycerides into absorbable fatty acids. The blocked fat is then eliminated from your body naturally, reducing your overall calorie intake.
Why This Mechanism Makes Orlistat Effective
The fat-blocking mechanism of orlistat provides measurable calorie reduction with each meal. Since fat contains 9 calories per gram compared to 4 calories per gram for carbohydrates and protein, blocking fat absorption can significantly reduce daily calorie intake when combined with a lower-fat diet. Generic orlistat 120mg costs from £29.69 for 4 weeks with EDM10, while branded Xenical 120mg costs £38.69 for the same period. Both contain identical active ingredients and work through the same proven mechanism.
Orlistat vs Alli: Mechanism Comparison
While orlistat 120mg blocks approximately one third of dietary fat, Alli contains orlistat 60mg - exactly half the prescription dose. The lower dose means Alli blocks a smaller proportion of dietary fat compared to prescription-strength orlistat. For those seeking the full fat-blocking mechanism, prescription orlistat 120mg or Xenical 120mg provides maximum efficacy. Alli 60mg costs from £26.09 for 4 weeks, while prescription orlistat offers greater fat-blocking potential from £29.69.
How the Fat-Blocking Mechanism Affects Your Body
Understanding how orlistat's mechanism works helps explain the gastrointestinal side effects some patients experience. When approximately one third of dietary fat passes through unabsorbed, it can cause oily stools, increased bowel movements, or oily spotting. These effects are actually signs that the fat-blocking mechanism is working. Keeping meals low in fat (approximately 15g per meal) minimises these effects while maintaining the weight loss benefits of orlistat's proven mechanism.
