How It Calculates the Results

This calculator uses the Mifflin-St Jeor Equation to estimate your Basal Metabolic Rate (BMR), which is the number of calories your body needs at rest. It then multiplies your BMR by an activity factor that corresponds to your typical activity level to estimate your total daily calorie needs.

Limitations

Please note that while this calculator provides a good estimate of your daily calorie needs, it has limitations:

  • The results are based on general population averages and may not be accurate for everyone.
  • Factors such as muscle mass, metabolic health, and specific lifestyle factors are not taken into account.
  • Always consider consulting with a healthcare provider for personalized dietary advice.
