2. BMI Thresholds

Once a person knows their BMI, they can use it to find out into which weight category they fall. Different countries have slightly different thresholds for these categories. In the USA, anybody with a BMI less than 18.5 is considered underweight. A BMI between 18.5 and 24.9 is healthy. People with a BMI between 25-29.9 are in the overweight range. Anyone with a BMI over 30 is classified, by this standard, as obese.
