What is a healthy amount of weight to lose on a weekly basis?

Depending on your current weight, 1-2 pounds weekly is considered healthy weight loss. More than that is not fat being lost; rather it is muscle tissue and water. If you have a lot of weight to lose, you will likely lose more than 2 pounds per week for the first weeks of the diet; if you have 10-20 pounds to lose, shoot for one pound per week.
