Body Mass Index is a measurement of a weight to height ratio.
This measurement, along with waist circumference, can help determine
health risks.
For those who fall under a high-risk category, a mere 10% weight
reduction can reduce health risks significantly. Realistic weight
goals are more important than ideal body weights.

Clinical judgment must be used in interpreting BMI. The presence
of edema, high muscularity, muscle wasting, age, and shortness
of stature can all affect BMI measurements. These circumstances
do not markedly influence the validity of BMI for classifying
individuals into risk categories.
