Understanding BMR
- BMR: Calories burned at complete rest for basic life functions
- Factors affecting BMR: Age, gender, weight, height, body composition
- Metabolism: BMR accounts for 60-75% of total daily energy expenditure
- Accuracy: Mifflin-St Jeor is most accurate for most people
Recommendations
- Use BMR as a starting point for calorie calculations
- Multiply by activity factor to get total daily energy needs
- Monitor weight changes and adjust as needed
- Focus on sustainable habits rather than extreme calorie restriction
- Consider body composition changes over time
Important: This calculator provides estimates only. Individual BMR can vary significantly
based on genetics, muscle mass, thyroid function, and other factors. Consult with healthcare providers
for personalized advice.
