Calorie Calculator: Your Personalized Daily Energy Needs

Understanding your daily caloric needs is fundamental to maintaining a healthy weight and achieving your fitness goals. Our evidence-based calculator uses the Mifflin-St Jeor equation, recognized by nutrition professionals as one of the most accurate methods for estimating daily calorie requirements.

How Our Calorie Calculator Works

The calculator considers several key factors to determine your daily calorie needs:

  • Basal Metabolic Rate (BMR)
  • Physical Activity Level
  • Age and Sex
  • Current Height and Weight

Each component plays a crucial role in calculating your Total Daily Energy Expenditure (TDEE), ensuring you receive accurate, personalized results.

Understanding Your Results

Your daily caloric needs are presented as a range rather than a fixed number because:

  1. Your daily activity levels naturally fluctuate
  2. Metabolic rates vary slightly day to day
  3. Different types of activities burn varying amounts of calories
