How do i calculate percentage of excess body weight i have lost after gastric sleeve?

Calculate: Look up what your ideal body weight is. Subtract your ideal body weight from your original weight. That number is the denominator representing your total excess weight. The numerator is the amount of weight you have actually lost. So if your excess weight was 50 lbs and you have lost 20 lbs, you have lost 20/50=40% of excess body weight.

It's All in the Math: Your % excess weight lost following a bariatric procedure requires that you know what your weight before surgery was (call that "wbs"). You will also need to know your weight right now (call that "wrn"). We also need to know your target weight your doctor wants you to reach (call that "tw"). Now, plug in the numbers to the following formula: (wbs-wrn)/(wbs-tw) x 100= % excess weight lost.

Use algebra: Well, if you slept through your high school algebra class, here's how to do it: first, figure out your ideal body weight by using tables provided on the internet using your height. Secondly, subtract this number from your pre surgical max weight. This gives you your excess body weight. Multiply the weight you lost since surgery by 100, divide by the excess body weight and you will have your %!
