Introduction: Determining how many calories you need each day is a fundamental step towards maintaining a healthy lifestyle. The How Many Calories Do I Need A Day Calculator utilizes the Harris-Benedict Equation to estimate your daily caloric requirements based on factors like gender, age, weight, height, and activity level.

Formula: The calculator employs the Harris-Benedict Equation, which calculates the Basal Metabolic Rate (BMR) based on gender, weight, height, and age. The BMR is then multiplied by an activity factor to determine the total daily calorie expenditure.

How to Use:

1. Select your gender.
2. Enter your age in years.
3. Input your weight in kilograms.
4. Enter your height in centimeters.
5. Choose your activity level from the dropdown.
6. Click the “Calculate” button to obtain an estimate of your daily caloric needs.

Example: For instance, a 30-year-old male with a weight of 75 kg, height of 180 cm, and a moderately active lifestyle would input 30 for age, select “male” for gender, enter 75 for weight, 180 for height, and choose “moderate” as the activity level. Click “Calculate” to get an estimate of the calories needed per day.
