Configuring loss %

How do you figure out the percent of body mass you've lost? Sheryl In the Zoo

Sheryl: My doc has a thing that looks like a scale that they have you stand on, it measures lean body mass and fat and gives the percentages. I think you have to have that kind of machine or do a water immersion test to find out (at least the most accurate way). There is probably some formula that could give you estimates. I'll do some searching. Pam

Go to the bottom of my profile and put in your numbers on my BMI index and it will tell you where your BMI is now at your present weight. You can also put in the starting weight and then figure the difference. Otherwise I found this formula: Body Fat Formula For Women Factor 1 (Total body weight x 0.732) + 8.987 Factor 2 Wrist measurement (at fullest point) / 3.140 Factor 3 Waist measurement (at naval) x 0.157 Factor 4 Hip measurement (at fullest point) x 0.249 Factor 5 Forearm measurement (at fullest point) x 0.434 Lean Body Mass Factor 1 + Factor 2 - Factor 3 - Factor 4 + Factor 5 Body Fat Weight Total bodyweight - Lean Body Mass Body Fat Percentage (Body Fat Weight x 100) / total bodyweight Body Fat Formula For Men Factor 1 (Total body weight x 1.082) + 94.42 Factor 2 Waist measurement x 4.15 Lean Body Mass Factor 1 - Factor 2 Body Fat Weight Total bodyweight - Lean Body Mass Body Fat Percentage (Body Fat Weight x 100) / total bodyweight

Oh I'll have to try this Pam, thanks! Maybe I worded it wrong, but what I want to figure out is how much (percentage wise) I've lost. Sheryl In the Zoo 375/290/???

i think your question has been misunderstood. i *think* you want to subtract 290 from 375 (85lbs) and determine what percentage of 375 is equal to 85lbs. i wish i remembered my basic math and i'd help you out! I think you're looking at around 22% but i won't swear to it.

Thanks Jay! That's the number I got (22%) but wasn't sure I did it right. Thanks again! Sheryl In the zoo

I think Jay gets and A for the day. That sounds about right to me. Dr. Schuhknecht figured at my lowest weight I had lost 103% of my xtra weight. I didn't like that figure but the BMI calc said I should weigh 174 lbs - no way jose' - I'd be one sick puppy at that weight. kp @ goal

the figure that jay figured is right. But don't go by the bmi index for your ideal body weight unless you have tiny bones. I am 168 now and by that index it says i'm overweight. But my surgeon says it doesn't take into account our bone density....i am very big boned , but only 5'3....according to the bmi index i should weigh 130 pounds and my surgeon says that is way to much for me to lose....he actually says i need to start maintaining now because after i do all the plastics i will be at idea weight for me if not underweight. My husband and everyone is trying to make me eat, but i stick with the program and add a little extra here and there, but nothing bad. ask your surgeon what he thinks. Hugs Linda

I absolutely agree that the BMI chart is crazy. I would have to lose another 15 lbs to be in the "normal" category and I'm already a size 8. I would be a stick if I los another 15 lbs. They really need to re-do that chart. My doctors say that, too! I know, I know, I'm not NORMAL! Pam

I think you divide the amount lost by your starting weight.. then move the decimal two places to the left... I think... like me... 286.5-224.5 =62 62/286.5 = .2164 .2164 = 21.64% I think don't hold me to it... (((HUGS))) Dori
