1. What is the Calorie Burn Equation?

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

2. How Does the Calculator Work?

The calculator uses the calorie burn equation:

\[ Calories = MET \times Weight \times \frac{Time}{60} \]

Where:

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

Explanation: The equation calculates calories burned by multiplying the MET value (which represents activity intensity) by body weight and the fraction of time spent in hours.

3. Importance of MET Values

Details: MET values standardize the energy cost of physical activities. One MET is defined as the energy cost of sitting quietly (approximately 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 2 for light activities to 10+ for vigorous exercises), 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 available 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 but individual variations in metabolism, fitness level, and body composition affect actual calorie burn.

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

Q4: Does this account for afterburn effect?
A: No, the equation only calculates 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 calorie expenditure, but remember that dietary intake is typically more important for weight loss than exercise alone.
