The Proven Mechanism: Why Orlistat Works for Weight Loss
How Orlistat's Fat-Blocking Mechanism Works
Orlistat works by inhibiting lipase enzymes in your digestive system. These enzymes normally break down dietary fat so your body can absorb it. When orlistat blocks approximately one third of these enzymes, that proportion of fat cannot be digested or absorbed. Instead, it passes through your system naturally. This proven mechanism is why orlistat 120mg from £16.89 (£15.20 with EDM10) delivers clinical results when combined with a reduced-calorie, lower-fat diet.
Can Orlistat Cause Constipation? Understanding the Real Effects
Orlistat's mechanism typically causes the opposite of constipation. Because approximately one third of dietary fat passes through undigested, most patients experience softer, more frequent stools rather than constipation. This is actually proof the medication is working. The unabsorbed fat creates characteristic oily or fatty stools, increased bowel frequency, and urgent bowel movements. These gastrointestinal effects demonstrate orlistat's fat-blocking action.
Why This Mechanism Proves Orlistat Works
The visible evidence of orlistat's mechanism – unabsorbed fat in stools – provides proof of effectiveness. When you see oily discharge or fatty stools, you're witnessing approximately one third of your dietary fat being blocked from absorption. This translates to reduced calorie intake from fat, supporting weight management alongside your reduced-calorie diet. Generic orlistat 120mg (£32.99 for 4 weeks, £29.69 with EDM10) provides the same proven mechanism as branded Xenical at better value.
Maximising Orlistat's Mechanism While Minimising Side Effects
Understanding orlistat's mechanism helps you use it effectively. Keep fat intake to approximately 15g per meal to optimise the blocking effect while reducing gastrointestinal side effects. The mechanism works best with three main meals containing moderate fat levels. High-fat meals increase side effects because more unabsorbed fat passes through your system. This is why dieticians recommend spreading your daily fat intake evenly across meals when taking orlistat.
Orlistat vs Xenical: Same Mechanism, Different Prices
Both orlistat 120mg and Xenical 120mg work through identical fat-blocking mechanisms. The active ingredient and dose are the same, so the clinical effect is equivalent. Generic orlistat provides proven mechanism benefits at lower cost – 4 weeks costs £32.99 (£29.69 with EDM10) compared to Xenical at £42.99 (£38.69 with EDM10). Alli 60mg uses the same mechanism at half dose, blocking a smaller proportion of dietary fat with typically milder effects.
