Use this tool to estimate the number of calories you need daily based on your activity level and personal information.
How to Use the Calorie Calculator
To use the calorie calculator, enter your age, weight in kilograms, height in centimeters, select your gender, and choose your activity level from the dropdown. Click the “Calculate” button to see your daily calorie intake requirement.
How It Calculates the Results
The calculator uses the Mifflin-St Jeor Equation to estimate your Basal Metabolic Rate (BMR), which is the number of calories your body needs to maintain basic physiological functions at rest. The equation is as follows:
- For men: BMR = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) – (5.677 x age in years)
- For women: BMR = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) – (4.330 x age in years)
This BMR is then multiplied by an activity level factor to estimate the total daily calorie intake needed to maintain your current weight:
- Sedentary (little or no exercise): BMR x 1.2
- Lightly active (light exercise/sports 1-3 days/week): BMR x 1.375
- Moderately active (moderate exercise/sports 3-5 days/week): BMR x 1.55
- Active (hard exercise/sports 6-7 days a week): BMR x 1.725
- Very active (very hard exercise/sports & physical job): BMR x 1.9
Limitations
While this calculator provides an estimate of your daily calorie needs, it does not account for factors such as muscle mass, overall health, or specific dietary needs. Always consult with a healthcare provider or a nutritionist for personalized advice.
