Alli works by inhibiting pancreatic lipase, an enzyme your body uses to break down fats in your food. This means less fat is absorbed into your bloodstream.
How much fat is blocked?
Alli blocks about 25% of the fat you consume. This isn’t a magic bullet, and you’ll still absorb a significant portion of dietary fat.
What happens to the unabsorbed fat?
The undigested fat passes through your digestive system and is eliminated in your stool. This can lead to oily stools and gas, common side effects of Alli.
Is it suitable for everyone?
Alli isn’t for everyone. Consult your doctor before use, especially if you have any underlying health conditions or are taking other medications. It’s particularly important to discuss it if you have conditions affecting fat absorption or liver function.
Dietary considerations matter
Remember: Alli’s effectiveness is maximized when combined with a reduced-calorie, low-fat diet and regular exercise. It’s a tool to aid weight loss, not a replacement for healthy lifestyle choices. A balanced approach is key.
