This tool helps you calculate your total daily calorie needs based on your personal information and activity level.
How to Use the Calorie Calculator
To use this calculator, simply fill out the form with your details: your age, gender, weight, height, and activity level. Once you’ve filled out all the fields, click the “Calculate” button to see your recommended daily caloric intake.
How It Calculates the Results
This calculator uses the Harris-Benedict Equation which has been revised to improve accuracy. It first calculates your Basal Metabolic Rate (BMR), which is the number of calories your body needs at rest to maintain basic bodily functions. The BMR is calculated differently for males and females:
- For males: BMR = 88.362 + (13.397 * weight in kg) + (4.799 * height in cm) – (5.677 * age in years)
- For females: BMR = 447.593 + (9.247 * weight in kg) + (3.098 * height in cm) – (4.330 * age in years)
Then, based on your chosen activity level, the BMR is multiplied by an activity factor:
- 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
- Very active (hard exercise/sports 6-7 days a week): BMR x 1.725
- Super active (very hard exercise/sports & a physical job): BMR x 1.9
Limitations
This calculator provides an estimate of your daily caloric needs based on the information provided. It does not take into account things like body composition or special dietary needs. Always consult with a healthcare provider for personalized nutrition advice.
