1. What is the Calories Burned Formula?

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

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( \text{MET} \) — Metabolic Equivalent of Task (dimensionless)
• \( \text{weight} \) — Body weight in kilograms
• \( \text{time} \) — Duration of activity in minutes

Explanation: The formula calculates calories burned by multiplying the MET value (which represents the intensity of the activity) by body weight and duration, then dividing by 60 to convert to kilocalories.

3. Importance of Calculating Calories Burned

Details: Knowing calories burned helps in weight management, exercise planning, and understanding energy expenditure for various activities.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is a MET value?
A: MET (Metabolic Equivalent of Task) is a unit that represents the energy cost of physical activities. 1 MET is the energy expended at rest.

Q2: 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 (8-12 MET), cycling (4-10 MET).

Q3: How accurate is this calculation?
A: It provides a reasonable estimate but individual variations in metabolism, fitness level, and body composition affect actual calories burned.

Q4: Should I use kg or pounds for weight?
A: The formula requires weight in kilograms. To convert from pounds, divide by 2.205.

Q5: Can I use this for weight loss planning?
A: Yes, it can help estimate exercise contribution to calorie deficit, but nutrition and other factors are equally important for weight loss.
