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) Calories Needed: Calculate

Introduction: The James Smith Calorie Calculator is a tool designed to estimate your daily calorie needs based on factors such as weight, height, age, gender, and activity level. Understanding your calorie requirements is essential for maintaining, gaining, or losing weight in a healthy and controlled manner.

Formula: The calculator uses the Harris-Benedict Equation to calculate the Basal Metabolic Rate (BMR), which represents the number of calories your body needs at rest. The BMR is then multiplied by an activity factor based on your chosen activity level to estimate your total daily calorie needs.

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 to obtain your estimated daily calorie needs.

Example: For example, a 30-year-old female weighing 60 kg, measuring 160 cm, and engaging in moderate exercise 3-5 days a week would use the calculator to estimate her daily calorie needs.
