How Do You Calculate Calories

Weight (in kg): Height (in cm): Age: Gender: Male Female Activity Level: Sedentary (little or no exercise) Lightly Active (light exercise/sports 1-3 days/week) Moderately Active (moderate exercise/sports 3-5 days/week) Very Active (hard exercise/sports 6-7 days a week) Extra Active (very hard exercise/sports & physical job or 2x training) Calculate

Your Estimated Daily Calories:

Introduction: Calculating your daily calorie needs is essential for managing your weight and maintaining a healthy lifestyle. This calculator uses the Harris-Benedict Equation to estimate your Basal Metabolic Rate (BMR) and adjusts it based on your activity level.

Formula: The calculator uses the Harris-Benedict Equation to calculate BMR:

• For males: BMR = 88.362 + (13.397 * weight) + (4.799 * height) – (5.677 * age)
• For females: BMR = 447.593 + (9.247 * weight) + (3.098 * height) – (4.330 * age)

The BMR is then multiplied by an activity factor based on your activity level (sedentary, lightly active, moderately active, very active, extra active) to get your estimated daily calories.

How to Use:

1. Enter your weight in kilograms.
2. Enter your height in centimeters.
3. Enter your age in years.
4. Select your gender.
5. Choose your activity level.
6. Click the “Calculate” button.
7. View your estimated daily calories in the result section.

Example: For example, a 30-year-old male (70 kg, 175 cm) with a moderately active lifestyle might have an estimated daily calorie intake of around 2600 calories.
