Hi,
I talk with the nutritionist ,the BMI figure is correct .
1. <25 is normal;
2. 25-30=overweight,
3.>30 is class 1 obesity
and when the BMI is between 30-40 , then it will be obesity class 2 and 3.
One of the formula to find our your BMI (Body Mass Index) is
your weight in pounds x703 divided by your height in inches twice.
For example if you are 155 pounds and you are 5 feet and 6 inches(66inches) tall your BMI will be:
155×703=108965 then devided by 66=1650.99 and again devided the 1650.99 by 66 ;the result is 25.01 which is the high normal or they can call it overweight
God bless.
