What is the difference between BMR and TDEE?

BMR (Basal Metabolic Rate) is calories burned at complete rest. TDEE (Total Daily Energy Expenditure) is BMR plus calories from daily activities and exercise.

Which BMR formula is most accurate?

Mifflin-St Jeor is most accurate for general population. Katch-McArdle is best for lean, athletic individuals when body fat is known.

How accurate are BMR calculations?

BMR formulas are accurate within ±10-15% for most people. Individual variations due to genetics, muscle mass, and medical conditions can affect accuracy.

Should I eat below my BMR for weight loss?

Generally no. Eating significantly below BMR can slow metabolism and cause muscle loss. Create deficits from TDEE through diet and exercise.

How often should I recalculate my BMR?

Recalculate when your weight changes by 5+ pounds, activity level changes significantly, or every 3-4 months during active weight management.

What factors can affect my metabolic rate?

Age, gender, muscle mass, genetics, thyroid function, stress, sleep quality, diet composition, and regular exercise all influence metabolic rate.
