Introduction: Understanding your daily calorie needs is a fundamental aspect of managing your diet and maintaining a healthy lifestyle. The Calories Needed Per Day Calculator assists you in determining the number of calories you should consume each day, taking into account your age, gender, weight, height, and activity level.
Formula: The Calories Needed Per Day Calculator utilizes the Harris-Benedict equation to estimate the Basal Metabolic Rate (BMR) based on your age, gender, weight, and height. The BMR represents the number of calories your body needs to maintain basic functions at rest. The equation for BMR varies 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)
The BMR is then adjusted based on your activity level:
- Sedentary: BMR * 1.2
- Lightly active: BMR * 1.375
- Moderately active: BMR * 1.55
- Very active: BMR * 1.725
- Super active: BMR * 1.9
How to Use:
- Enter your age in years.
- Select your gender (male or female) from the dropdown menu.
- Input your weight in kilograms.
- Specify your height in centimeters.
- Choose your activity level from the dropdown menu.
- Click the “Calculate” button.
Example: Suppose you are a 25-year-old male with a weight of 70 kg, a height of 175 cm, and a moderately active lifestyle. Here’s how to use the calculator:
- Enter “25” as your age.
- Select “Male” from the gender dropdown.
- Input “70” for your weight.
- Specify “175” as your height.
- Choose “Moderately active” from the activity level dropdown.
- Click “Calculate.”
The calculator will display: “Calories Needed Per Day: [calculated value] kcal.”
