Introduction
Understanding your daily calorie needs is crucial for maintaining a balanced diet and achieving your health and fitness goals. Our Calories Per Day Calculator is designed to help you estimate your daily calorie requirements based on factors such as your weight, height, age, gender, and activity level. In this article, we’ll guide you on how to effectively use this tool to plan your daily calorie intake.
Formula for Calculating Calories Per Day
The Calories Per Day Calculator employs the Harris-Benedict equation, which calculates your Basal Metabolic Rate (BMR) based on your weight, height, age, and gender. It then adjusts the BMR based on your activity level. The formula can be described as follows:
- For Males: BMR = (10 * weight in kg) + (6.25 * height in cm) – (5 * age in years) + 5
- For Females: BMR = (10 * weight in kg) + (6.25 * height in cm) – (5 * age in years) – 161
After calculating the BMR, it’s 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
This final figure represents your estimated daily calorie needs.
How to Use
Our Calories Per Day Calculator is simple to use and can be utilized by following these steps:
- Input your weight in kilograms.
- Input your height in centimeters.
- Input your age in years.
- Select your gender (Male or Female).
- Select your activity level from the dropdown menu (Sedentary, Lightly Active, Moderately Active, or Very Active).
- Click the “Calculate” button.
The calculator will instantly provide an estimate of your daily calorie needs.
Example
To illustrate how the calculator works, let’s consider an example:
- Weight: 70 kg
- Height: 170 cm
- Age: 30 years
- Gender: Female
- Activity Level: Moderately Active
Calculating BMR: BMR = (10 * 70) + (6.25 * 170) – (5 * 30) – 161 = 1299.5 calories
Adjusting for activity level (Moderately Active): Calories Per Day = BMR * 1.55 = 1299.5 * 1.55 = 2013.725 calories per day
So, this individual would need approximately 2013.73 calories per day to support their daily calorie needs with a moderately active lifestyle.
