About BMR & TDEE
What is BMR?
Basal Metabolic Rate (BMR) is the number of calories your body needs to perform basic life-sustaining functions while at rest. This includes breathing, circulation, cell production, and nutrient processing.
What is TDEE?
Total Daily Energy Expenditure (TDEE) is your BMR multiplied by an activity factor. It represents the total calories you burn in a day, including all activities.
Mifflin-St Jeor Formula (Used for BMR):
- Men: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) + 5
- Women: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) - 161
Activity Multipliers:
- Sedentary: BMR × 1.2
- Lightly Active: BMR × 1.375
- Moderately Active: BMR × 1.55
- Very Active: BMR × 1.725
- Extra Active: BMR × 1.9
Important Notes:
- These are estimates based on averages and may not be exact for everyone
- Individual metabolism can vary based on genetics, muscle mass, and other factors
- Consult a healthcare professional or nutritionist for personalized dietary advice
- Extreme calorie restriction can be harmful - maintain a balanced approach
