Body Mass Index

My GM of Human Capital & Support Services (HCSS) presented the findings on the Body Mass Index (BMI) of our staff. However, only 47% of some 800++ total staff were taken their heights and weights for the BMI calculation.

BMI's calculation...
And what does it means?
So, of the 47% staffs measured, a hefty 35.73% are overweight and obese. I'm not sure the graph will tilt to which end, if the other 53% staffs are measured?! And, worryingly, average age for my organization is 28+.

Would this drink helps to achieve desirable weight status?! Emmm....
