About BMI & Its Limitations
BMI is a screening tool, not a diagnostic measure. It does not account for muscle mass, bone density, ethnic differences, or fat distribution. A muscular athlete may have a high BMI but low body fat.
TDEE is calculated using the Mifflin-St Jeor equation — the most validated formula for BMR estimation in clinical settings. TDEE multiplies BMR by an activity factor.
