If you’re into bodybuilding or just trying to maintain a healthy lifestyle, knowing your daily calorie expenditure is crucial. It helps you determine how many calories you need to consume to meet your fitness goals. This Daily Calorie Expenditure Calculator for Bodybuilding is designed to make that process simple and efficient.

Formula: The calculator uses the Harris-Benedict equation to estimate your Basal Metabolic Rate (BMR) and then adjusts it based on your activity level. The formula for BMR differs based on your gender:

• 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 final daily calorie expenditure is calculated by multiplying the BMR by your chosen activity level factor.

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 (male or female).
