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.
How common is a BMI of 21.9 for a 5ft 7in female?
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.
If I lose 10 lbs, what will my new BMI be?
If you lose 10 lbs from your current weight of 140 lbs, your new BMI would be approximately 20.4 at the same height of 5ft 7in. This would represent a change of 1.5 BMI units.
