What is BMR and TDEE in Health and Nutrition?
Understanding your body's energy expenditure is vital for effective weight management and meal planning. BMR (Basal Metabolic Rate) represents the minimum number of calories your body needs to perform basic life-sustaining functions at rest. TDEE (Total Daily Energy Expenditure) accounts for your BMR plus the extra calories burned through physical activities and food digestion.
The Science Behind Metabolism Calculations
This tool uses the highly accurate Mifflin-St Jeor formula to compute resting metabolic rates instantly based on your physical metrics.
Calculation Formula:
1. BMR = $(10 \times \text{weight}) + (6.25 \times \text{height}) - (5 \times \text{age}) + 5$
2. TDEE = $\text{BMR} \times \text{Activity Multiplier}$
1. BMR = $(10 \times \text{weight}) + (6.25 \times \text{height}) - (5 \times \text{age}) + 5$
2. TDEE = $\text{BMR} \times \text{Activity Multiplier}$
Frequently Asked Questions (FAQ)
Q: Why is tracking BMR important for food and diet?
A: Knowing your BMR prevents you from undereating or overeating, ensuring your diet matches your exact energy needs.
