I'm apparently 16% body fat, but I look like I'm 23%. Why is that?

[dianeprove]

Any reason that may be?
Here are my stats;
neck: 11inches
Waist: 25inches
Hip: 31inches
Wrist: 6inches
Heigh: 62inches

if that does add up to 16% how come I dont look like it?
(Is it because I barely go poop!?)

I don't know how you added, but you can't calculate body fat based on height and girth. The best method, aside from laboratory tests, is using skinfolds.
