Keisan Calorie Calculator – Accurate Calorie Counting

This tool will help you calculate your daily calorie needs based on your personal information and activity level.







How to Use the Calorie Calculator

To use the calculator, follow these steps:

  1. Enter your weight in kilograms.
  2. Enter your height in centimeters.
  3. Enter your age.
  4. Select your gender.
  5. Choose your activity level from the dropdown menu.
  6. Click the “Calculate” button.

How It Calculates the Results

The calculator uses the Harris-Benedict equation to estimate your Basal Metabolic Rate (BMR), which represents the number of calories you would burn per day at rest.

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

The result is then multiplied by an activity factor to estimate your total daily calorie needs based on your activity level:

  • Sedentary: BMR * 1.2
  • Lightly active: BMR * 1.375
  • Moderately active: BMR * 1.55
  • Active: BMR * 1.725
  • Very active: BMR * 1.9

Limitations

This calculator provides an estimate of your calorie needs. Individual calorie requirements can vary based on factors not considered by the calculator, such as muscle mass, metabolic health, and specific dietary needs. Always consult with a healthcare provider for personalized dietary advice.
