alli is the only clinically proven, pharmacy-only weight loss medicine in the UK.

alli is used for weight loss alongside a reduced calorie, low-fat diet, in overweight adults, aged 18 or over.

alli is clinically proven to help you lose more weight than dieting alone. For every 2 pounds you lose through healthy eating, Alli can help you lose 1 pound more*.

The capsules work only in your digestive system to stop around a quarter of the fat in your diet from being absorbed. This fat passes out of your body and may cause changes to your bowel movements. Eat lower-fat meals to help manage these effects. For adults with a BMI of 28 or above. Always read the label.

*when used in combination with a reduced-calorie, low-fat diet.
