1. What is the Calorie Expenditure Equation?

The calorie expenditure equation estimates calories burned during physical activity using MET (Metabolic Equivalent of Task) values, which represent the energy cost of activities. This calculation helps quantify exercise intensity and energy expenditure.

2. How Does the Calculator Work?

The calculator uses the calorie expenditure equation:

Where:

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

Explanation: The equation multiplies the activity's MET value by body weight and duration to estimate total calories burned.

3. Importance of MET Values

Details: MET values standardize exercise intensity. 1 MET = resting metabolic rate (~1 kcal/kg/hour). Common values: walking (3-5 MET), running (8-12 MET), cycling (6-10 MET).

4. Using the Calculator

Tips: Enter accurate MET value for your activity, weight in kg, and duration in hours (e.g., 30 minutes = 0.5 hours). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

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

Q2: Is this calculation accurate for everyone?
A: It provides estimates. Individual factors like fitness level, body composition, and exercise efficiency affect actual calories burned.

Q3: Should I use kg or pounds for weight?
A: The equation requires weight in kilograms. To convert from pounds, divide by 2.205.

Q4: How accurate are MET values?
A: MET values are averages. Actual energy expenditure varies based on intensity, terrain, technique, and individual physiology.

Q5: Can I use this for weight loss planning?
A: Yes, but combine with dietary monitoring for comprehensive weight management. Remember that calorie estimates have margins of error.
