this issue was raised a little while ago... I believe one of the indicators they use is BMI - body mass index... which is...
weight (kgs)/ height (cm) squared...
so is approximatly 92kgs/1.89*1.89 gives me BMI 26
25 is in theory the "ideal" with less than 20 underweight and more than 30 overweight...
I did orginally have a BMI of 31 I was a little chubby (2 months in the states on hot dogs and dunkin' donuts) but its only taken me a couple of months of 'proper' eating habits to get down to an 'acceptable' weight.
