For those who are overweight and obese, you are considered as overweight if your BMI is between 25 to 30, in the obese class I if your BMA ranges somewhere between 30 to 35, in the obese class II if it is between 35-40, and in the obese class III if your BMI is greater than 40.

Lastly, the child or teen can be deemed as overweight if they fall outside the 95% percentile.
