1. What is the Calories Burned Equation?

The calories burned equation estimates energy expenditure during physical activity using MET (Metabolic Equivalent of Task) values, weight, and duration of activity. It provides a practical way to estimate calorie expenditure for various exercises.

2. How Does the Calculator Work?

The calculator uses the calories burned equation:

Where:

• \( MET \) — Metabolic Equivalent of Task (unitless)
• \( Weight \) — Body weight in kilograms
• \( Time \) — Duration of activity in hours

Explanation: The equation multiplies the intensity of the activity (MET) by your body weight and the time spent doing the activity.

3. Importance of MET Values

Details: MET values represent the energy cost of physical activities. One MET is defined as the energy expenditure while sitting quietly (approximately 1 kcal/kg/hour).

4. Using the Calculator

Tips: Enter the MET value for your activity (common values range from 2-12), your weight in kg, and the duration in hours. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find MET values for different activities?
A: The Compendium of Physical Activities provides comprehensive MET values for hundreds of activities.

Q2: How accurate is this calculation?
A: It provides a reasonable estimate but individual factors like fitness level and body composition can affect actual calorie burn.

Q3: Should I use my current weight or ideal weight?
A: Always use your current weight for the most accurate estimation.

Q4: Can I use this for weight loss planning?
A: Yes, it can help estimate exercise contribution to calorie deficit, but remember that diet is typically more important for weight loss.

Q5: What's the difference between kcal and calories?
A: In nutrition, "Calorie" (capital C) actually means kilocalorie (kcal), so they can be used interchangeably in this context.
