How Orlistat's Fat-Blocking Mechanism Supports Your Diet
How Orlistat Blocks Fat Absorption in Your Body
Orlistat works by inhibiting lipase enzymes in your digestive system that normally break down dietary fat. When you take orlistat with meals containing fat, it blocks approximately one third of that fat from being absorbed into your bloodstream. This unabsorbed fat passes naturally through your body, reducing your overall calorie intake from dietary fat. Understanding this mechanism helps explain why following a lower-fat diet is crucial for both effectiveness and minimising side effects.
What You Can Eat While Taking Orlistat
The key to success with orlistat is keeping each meal to approximately 15g of fat or less. Good food choices include lean proteins like grilled chicken, fish, and turkey, plenty of vegetables and salads with low-fat dressings, wholemeal bread and cereals, fresh fruits, and low-fat dairy products. Avoid high-fat meals like fried foods, fatty meats, full-fat dairy, nuts in large quantities, and rich sauces, as these significantly increase the likelihood of gastrointestinal side effects while reducing the medication's effectiveness.
Why This Mechanism Makes Orlistat Effective for Weight Management
Because orlistat blocks approximately one third of dietary fat absorption, it creates a calorie deficit that supports weight loss when combined with a reduced-calorie diet. Each gram of fat contains 9 calories, so blocking fat absorption can significantly reduce your daily calorie intake. This proven mechanism has made orlistat a trusted prescription weight loss treatment for adults with a BMI of 28 or above with weight-related health conditions, or 30 or above.
