also, how do you calculate what 85% of my ideal body weight would be?How do you calculate your percentage from an ideal body weight ?
ok let's see



http://www.nhlbi.nih.gov/guidelines/obes鈥?/a>



for 70 inches (5' 10") a bmi of 19 (healthy is 18.5-24.9) is 132 pounds.

so let's just use that as an ideal weight.



so let's say

(96/132) x 100 = 73% of your ideal weight.



for 85% you just do

(85/100) x 132 = 112 lbs



(i rounded off both the answers)



If i were you, I'd aim anywhere between 130-150 because even 112 is too underweight.How do you calculate your percentage from an ideal body weight ?
