How to properly determine the percentage of weight lost

Determining the percentage of weight you have lost is not as difficult as it may seem. The key is having a starting weight, taken prior to beginning your weight loss program, and a new weight, taken after performing your weight loss routine for at least a week. Once you have these weights, the rest is easy.

  Divide your new weight, taken after your training, by your weight prior to beginning your workout program. For example, if you weighed 250 lbs. prior to your workout program, and after two weeks of training you weigh 240 lbs, your equation will look like this: 240 / 250 = 0.96

• 2

  Subtract one from the answer in Step 1. If your answer to step one was 0.96, your equation will look like this: 0.96 - 1 = - 0.04

• 3

  Multiply your answer in Step 2 by 100 to get the percentage of weight lost. If your answer to Step 2 was - 0.04, your equation will look like this: - 0.04 x 100 = - 4.0. Thus, your percentage of weight lost over the two weeks of training was 4 percent.
