Excess weight lost (EWL) is a formula to determine during weight loss how much progress has been made along the way.
In the most simplest of terms, imagine a person's ideal weight was 100 pounds. Now, their current weight happens to be 200 pounds.
200 - 100 = 100 pounds excess weight
As this person loses weight, we can use the formula to determine what percentage of the 100 pounds of excess weight they have lost at any given time to mark their progress.
SW = starting weight
CW = current weight
IW = ideal weight (normal BMI)
(SW - CW) / (SW - IW) x 100 = percent excess weight lost
