excess weight loss percentage calculation

Hi kim if you wanted to get to normal BMI of 23 your excess weight was 142 and you lost 122 so you lost 116% of your excess weight if i am not mistaking.

Thank you so much!!!!

and for the person who asked..im 5 7and a half so 161 lbs puts me at a bmi of 24.8 (normal)

woot woot

Subtract your goal weight from your starting weight. ie. 300-150=150 lbs of excess weight.

If you've lost 50 lbs and weigh 250, you take 50 and divide by 150 x 100 for 33.3% of your excess lost.

Quick question re: the formula above (50/150x100)  Does the 150 represent the goal weight or the excess weight?
Thanks ... dar

150 in this case = the excess weight to be lost (ie. this person needs to lose 150 lbs of excess wt).

ie. in my case.

I have lost 62 lbs. I need to lose 160 of EWL so my calculation is:

62/160=0.3875 x 100 = 38.75%

I have lost 38.75% of my excess weight (EWL).

OMG Wendy,

I don't mean to throw a wrench in this, but the MIS Dietician calculates based on a BMI of 23 (some surgeon's office use BMI's of 21). So, you can do 2 calculations: 1) based on your own goal 2) based on BMI of 23 (which will align with Surgeon's/Dietician's calculation.

I just confirmed this at my last appt w Denise.

Take care,

Andrea.

21!!!!?? oh andrea!! *smacks you*

as if im EVER going to get to a bmi of twenty freaking one. LOL

just kidding. i love you.

ok so i have a bit further to go than i was claiming.

I will base it on a bmi of 23 from now on.  grrr *grumbles about bmis*

i just picked 24.8 cause its at the highest end of "normal"

thats all im hoping for at this point lol. if i can do better than that then thats just a bonus for me.

i knew there was a reason i havent gone to see denise. LOL

Hi Wendy,

Fortunately, our surgeons use 23! Not 21! They just need to use a constant number to measure all their patient's against.  

But, please don't compare yourself to 23. Compare to your own goal. Just know that there may be a slight variation when you get checked out either at your surgeon's office or at the Dietician.

My personal goal was just within the 25 BMI range too. Now, if I can get down a bit further, that's great, but I'm not going to lose sleep if I don't.

Take care,

Andrea

Would someone be kind enough to do mine please...

cw 164

Thanks so much

87%.

BTW - height doesn't play into this at all. :)

You want to lose 225 lbs (360-135).

You have lost 196.

196 / 225 = 0.871 x 100 = 87%
