Understanding Orlistat's Fat-Blocking Action
How Orlistat Works on Dietary Fat
Orlistat doesn't "burn" existing body fat. Instead, it works in your digestive system by blocking approximately one third of the fat you eat from being absorbed. This lipase inhibitor acts locally in the gut, preventing dietary fat from being broken down and absorbed into your bloodstream. The unabsorbed fat passes naturally through your body, reducing your calorie intake from dietary fat.
Timeline for Orlistat Effects
Orlistat begins working within 24-48 hours of your first dose. However, weight loss results vary between individuals and depend on following a reduced-calorie, lower-fat diet alongside the medication. Most people may notice initial effects within the first few days, but sustainable weight management requires consistent use as part of a structured programme including dietary and lifestyle changes.

Managing Expectations and Side Effects
Orlistat may cause gastrointestinal side effects, particularly when eating high-fat meals. Keep dietary fat to approximately 15g per meal to minimise side effects. Most side effects reduce as you adapt to a lower-fat diet. Remember, orlistat works best alongside reduced-calorie eating and regular physical activity. Always take exactly as prescribed by your healthcare professional.
