1. What is the Calorie Burn Formula?

The calorie burn formula estimates energy expenditure during physical activity using MET (Metabolic Equivalent of Task) values. This provides a standardized way to calculate calories burned across different types of exercises and intensities.

2. How Does the Calculator Work?

The calculator uses the calorie burn equation:

\[ Calories = MET \times Weight_{kg} \times Time_{hours} \]

Where:

\( MET \) — Metabolic Equivalent of Task (unitless)
\( Weight_{kg} \) — Body weight in kilograms
\( Time_{hours} \) — Duration of exercise in hours

Explanation: MET values represent the energy cost of physical activities as multiples of resting metabolic rate. One MET equals the energy expenditure while sitting quietly.

3. Importance of Calorie Burn Calculation

Details: Accurate calorie burn estimation helps in weight management, exercise planning, and understanding energy balance. It's essential for creating effective fitness and nutrition programs.

4. Using the Calculator

Tips: Enter MET value for your activity, weight in kilograms, and exercise duration in hours. Common MET values: Walking (3-5), Running (8-12), Cycling (4-10), Swimming (6-10).

5. Frequently Asked Questions (FAQ)

Q1: What are MET values?
A: MET (Metabolic Equivalent of Task) is a standard unit that estimates the energy cost of physical activities. 1 MET equals the oxygen consumption at rest (3.5 ml/kg/min).

Q2: How accurate is this calculation?
A: This provides a good estimate for general purposes, but individual factors like fitness level, body composition, and exercise efficiency can affect actual calorie burn.

Q3: Where can I find MET values for different activities?
A: The Compendium of Physical Activities provides comprehensive MET values for hundreds of activities, from household chores to sports.

Q4: Does this account for after-burn effect?
A: No, this calculation only estimates calories burned during the activity itself. High-intensity exercises may continue to burn calories after the workout (EPOC).

Q5: Can I use this for weight loss planning?
A: Yes, this calculator helps estimate exercise energy expenditure, which is useful for creating calorie deficit plans for weight loss.
