No loss in body fat?

skinnylion

In the last month I've lost 5 lbs and inches off of my neck, waist, and hips - but according to my spreadsheet, which uses the Military Body Fat equation, my body fat % is exactly the same as it was a month ago.

What gives?

If you are losing inches and you are losing weight, you are losing body fat. Those equations cannot be completely accurate.

weird. Did some other measurements go the opposite way ?

Nope, they are all less than they were before.

Does this just mean I'm losing proportionally or... what? I'm just confused. I was kind of hoping my BF% would have been lower.

Bump in case anyone else has any ideas.

It's the neck parameter....I don't know the exact equation it uses, but it must be a ratio with the neck and the other measurements...If you lower the neck, and keep everything else the same, it will report an increase in BF%.

Try holding the neck measurement constant and looking at the numbers.


ETA: Here's the equations- not a ratio, but the neck is subtracted from the other measurements.

For men[2], all measurements in inches:

%Fat = 86.010*LOG(abdomen - neck) - 70.041*LOG(height) + 36.76

For men, all measurements in centimeters:

%Fat = 86.010*LOG(abdomen - neck) - 70.041*LOG(height) + 30.30

For women, all measurements in inches:

%Fat = 163.205*LOG(abdomen + hip - neck) - 97.684*LOG(height) - 78.387

For women, all measurements in centimeters:

%Fat = 163.205*LOG(abdomen + hip - neck) - 97.684*LOG(height) - 104.912
