How much weight could I lose using Alli?

Alli may help you lose weight. But the weight loss will likely be modest. For example, it may be just a few pounds more than you would lose with diet and exercise alone.

In some studies, more than 40% of people taking Alli while following a calorie-restricted diet and increasing physical activity lost 5% or more of their body weight within a year. Clinically meaningful weight loss, generally defined as 5% or more of body weight, means that there is enough weight loss to begin lowering the risk of heart disease, diabetes and other diseases.

People who ate a calorie-restricted diet, exercised regularly and took Alli lost an average of 5.7 pounds (2.6 kilograms) more in one year than did people who only dieted and exercised.
