1. What is the Calories Burned Formula?

The formula calculates calories burned during physical activity based on the MET (Metabolic Equivalent of Task) value, body weight, and duration of activity. It provides an estimate of energy expenditure.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( MET \) — Metabolic Equivalent of Task (intensity of activity)
• \( weight \) — Body weight in kilograms
• \( time \) — Duration of activity in minutes

Explanation: The formula converts the MET value (which is based on kcal/kg/hour) to your specific weight and time duration.

3. Importance of MET Values

Details: MET values represent the energy cost of activities. 1 MET equals resting energy expenditure (about 1 kcal/kg/hour). Higher MET values indicate more intense activities.

4. Using the Calculator

Tips: Enter the MET value for your activity (common values range from 1-12), your weight in kg, and duration in minutes. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find MET values for different activities?
A: MET values are published in compendiums of physical activities. Common examples: walking (3-5 MET), running (7-12 MET), cycling (4-10 MET).

Q2: How accurate is this calculation?
A: It provides a reasonable estimate for most people, but individual metabolism, fitness level, and body composition can affect actual calories burned.

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

Q4: Does this account for afterburn effects?
A: No, this calculates only the calories burned during the activity. Some intense activities may increase calorie burn for hours afterward.

Q5: Can I use this for weight loss planning?
A: Yes, it can help estimate exercise energy expenditure, but remember that diet is typically more important for weight loss than exercise alone.
