From a public health policy standpoint, which argument is strongest for caution when using BMI thresholds alone to allocate resources for weight-related interventions?

• A. Because BMI is the same as percent body fat, there is no risk of misallocation when it is used as the sole criterion for interventions
• B. BMI thresholds may misclassify individuals (e.g., muscular athletes as obese and older adults with low muscle as healthy), potentially directing resources away from those with higher actual adiposity or metabolic risk
• C. BMI is universally precise across all populations and therefore should be the only measure used in policy decisions without any adjustments or complementary measures
• D. BMI thresholds should be discarded because waist circumference alone perfectly captures all dimensions of health risk and is simpler to implement than BMI

Answer: (B)
