Why Understanding the Mechanism Helps You Buy Smart
How Orlistat's Fat-Blocking Mechanism Actually Works
Orlistat works by inhibiting lipase enzymes in your digestive system. These enzymes normally break down dietary fat so it can be absorbed. When orlistat blocks these enzymes, approximately one third of the fat you eat cannot be digested or absorbed into your body. This unabsorbed fat passes naturally through your digestive system and is excreted.
This mechanism is why orlistat requires a prescription - it's a proven pharmaceutical intervention that directly reduces calorie absorption from dietary fat. Generic orlistat 120mg costs £32.99 for 4 weeks (£29.69 with EDM10), while branded Xenical costs £42.99 for 4 weeks (£38.69 with EDM10). Both contain identical 120mg doses.
What You Can Eat: The Low-Fat Rule
Because orlistat blocks approximately one third of dietary fat, keeping your fat intake low per meal minimises side effects significantly. Aim for no more than 15g fat per meal - this works with the mechanism rather than against it. Foods you can eat include lean proteins like chicken breast, white fish, and turkey. Choose low-fat dairy, plenty of vegetables, fruits, and whole grains.
Understanding this mechanism proves why orlistat works - it's not a placebo or appetite suppressant. It's a lipase inhibitor with a measurable, scientific effect on fat absorption. Order your treatment knowing you're buying proven pharmaceutical intervention.
Why Generic Orlistat Offers the Same Mechanism as Xenical
Both generic orlistat 120mg and branded Xenical 120mg contain identical active ingredients at identical doses. The fat-blocking mechanism is exactly the same - approximately one third of dietary fat absorption blocked. The difference is price: generic orlistat saves you around £9 per month compared to Xenical.
Many patients choose generic orlistat for value while others prefer branded Xenical. Clinically, the mechanism and effect are equivalent. Both require the same low-fat diet approach and both work through the same lipase inhibition process.
Foods to Avoid: High-Fat Meals and Side Effects
High-fat meals significantly increase gastrointestinal side effects because more unabsorbed fat passes through your system. Avoid fried foods, fatty meats, full-fat dairy, nuts, oils, and processed foods high in fat. These foods don't stop orlistat working - they make the mechanism more noticeable through increased side effects.
The mechanism means side effects are actually proof the medication is working. Oily stools and urgent bowel movements occur because approximately one third of dietary fat isn't being absorbed. This is the medicine functioning as designed.
