How to Calculate a Rate of Loss

Once you have started a diet a good way to measure your success is to calculate your rate of loss. That is how much weight you lose over a given amount of time, and the rate is commonly calculated by pounds per day or per week. It is normal for the rate of loss to decrease over the course of a diet because as the body loses weight it uses less energy to perform the same tasks. An easy mathematical formula can help you calculate your rate of weight loss.
