Understanding the Limitations

BMI is a useful screening tool for populations, but it doesn't measure body fat directly. It can be misleading for two specific groups:

Group	BMI Issue	Better Assessment
Athletes	May classify as "Overweight" due to high muscle mass.	Body Fat % or Waist-to-Hip Ratio
Seniors	May classify as "Normal" despite low muscle mass (Sarcopenia).	Functional strength testing
