I got bored and being the free-thinker that I am, I wondered "hmmmm.... I wonder how much my skeleton and organs weigh?" Then, remembering that I have one of those fancy scales that can calculate your body fat and h20 percentage, I decided to do some math.
If your machine outright tells you what your body fat and h20 content is, then it's pretty simple subtraction but if it just does percentages then it might be a little harder.
Take me for example. After plugging in that I am 20 years old, male, and approximately 6'1" tall, I step on the scale naked. It reports that I am 165.2 pounds, I have 30.2 pounds of body fat and 59.6% h20 content. First you have to convert your water content to pounds. Take your weight times 59.6% (In my case 165.2 x 0.596 to get 98.5 pounds) Then simple subtraction from there.
You don't have to tell us how much fat you have if you don't want to. But I believe your age, height, and gender act as a factor contributing to your core weight. I was just curious If this number changes between people.
My core weight is 36.5 pounds. Pretty amazing that almost 100 pounds of me is straight h20. Now time to work on converting that 30.2 pounds of body fat into muscle.
