This tool calculates your daily calorie needs based on your age, height, weight, gender, and activity level.
How to use the Calorie Calculator
Enter your age, gender, weight, and height into the fields. Select your activity level from the dropdown menu and click “Calculate”. The calculator will display your Basal Metabolic Rate (BMR) and your daily calorie needs based on your activity level.
Explanation of Calculation
The calculator uses the following formulas to calculate your calorie needs:
- BMR: Basal Metabolic Rate (BMR) is the number of calories required to keep your body functioning at rest. The Harris-Benedict equation is used for this:
- 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
- Daily Calorie Needs: This is calculated by multiplying your BMR by an activity factor that corresponds to your 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 and physical job): BMR * 1.9
Limitations
This calculator provides an estimate based on widely accepted formulas, but individual calorie needs can vary based on a variety of factors including genetics, medical conditions, and more. Always consider consulting with a healthcare provider or nutritionist for personalised dietary advice.
