Frequently Asked Questions
Is BMI the best measure of health at 21.9?
A BMI of 21.9 is a good indicator of healthy weight, but body composition and muscle mass are also important factors. For a more comprehensive health assessment, consider measuring waist circumference and body fat percentage in addition to BMI.
Can a BMI of 21.9 be healthy if I have belly fat?
While a BMI of 21.9 is within the normal range (18.5-24.9), waist circumference is an important complementary measure. The CDC recommends that women maintain a waist circumference below 35 inches to minimize health risks. Belly fat can increase cardiovascular risk even at a normal BMI.

The CDC reports that normal weight individuals make up roughly one-third of the US adult population, a figure that has been declining over the past two decades. Your BMI of 21.9 places you in the Normal category.
How much weight can I gain before reaching a BMI of 25?
To reach a BMI of 25 from your current BMI of 21.9, you could gain approximately -21.4 lbs at your current height of 5ft 6in before entering the overweight category.
