Do we put on weight as the age increases, if so can you provide the age & weight relations chart or details. thanks in advance.

BMI vs. age websites: I'm not 100% sure what u r looking 4, but as people age their body composition changes. (See Fig. 1 in http://www.merckmanuals.com/professional/pediatrics/principles_of_drug_treatment_in_children/pharmacokinetics_in_children.html). As a result, weight (wt) adjusted 4 height (ht) = BMI increases. See http://www.halls.md/body-mass-index/womens.htm 4 both male & female charts. BMI = wt[kg]/(ht[m])^2
