health check results

Got my yearly health check results back:
Height: 169.3 cm (5'6")
Weight: 78.0 k (171.9 lbs)
BMI: 27.2
OK, I admit I've got a nice gut going on and can stand to lose some weight; my BMI is too high and my suggested BMI is 22.
But my suggest weight is 62.4 k (137.5 lbs.) So I'm supposed to lose 15.6 k (34.4 lbs)?! I guess if I cut off a leg or something...
