Calorie Calculator

This calorie calculator uses the Mifflin-St Jeor Equation to estimate your Basal Metabolic Rate (BMR) and then applies an activity factor to estimate your total daily calorie needs.

How to Use the Calculator:

  1. Fill in your personal information (gender, age, weight, height).
  2. Select your activity level from the provided options.
  3. Click the “Calculate” button to see your estimated calorie needs.

How It Calculates the Results:

The calculator uses the following steps:

  1. It calculates your BMR using the Mifflin-St Jeor Equation:
    • For men: BMR = 10 * weight (kg) + 6.25 * height (cm) – 5 * age (years) + 5
    • For women: BMR = 10 * weight (kg) + 6.25 * height (cm) – 5 * age (years) – 161
  2. It then multiplies your BMR by an activity factor corresponding to your selected activity level:
    • Sedentary (little or no exercise): BMR * 1.2
    • Lightly Active (light exercise/sports 1-3 days/week): BMR * 1.375
    • Moderately Active (moderate exercise/sports 3-5 days/week): BMR * 1.55
    • Very Active (hard exercise/sports 6-7 days a week): BMR * 1.725
    • Super Active (very hard exercise/sports & physical job or 2x training): BMR * 1.9

Limitations:

This calculator provides an estimate based on average values and may not be accurate for everyone. Factors such as muscle mass, body composition, and other individual differences can affect your actual calorie needs. Always consult with a healthcare provider or a nutritionist for personalized recommendations.
