1. What is the Calorie Burn Formula?

The calorie burn formula estimates energy expenditure during physical activity using metabolic equivalents (METs), weight, and time. It provides a practical way to calculate calories burned during various exercises, including weight lifting.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: MET values represent the energy cost of physical activities. One MET is defined as the energy expenditure while sitting at rest.

3. Importance of Calorie Calculation

Details: Understanding calorie expenditure helps with weight management, exercise planning, and achieving fitness goals. It provides insight into the energy cost of different activities.

4. Using the Calculator

Tips: Enter MET value (typically 3-6 for weight lifting), weight in kg, and time in hours. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are typical MET values for weight lifting?
A: Weight lifting typically has MET values between 3.0-6.0, depending on intensity. Light effort is around 3.0 METs, while vigorous effort can reach 6.0 METs.

Q2: How accurate is this calculation?
A: This provides an estimate. Actual calorie burn can vary based on individual metabolism, exercise intensity, and other factors.

Q3: Should I use my current weight or goal weight?
A: Always use your current weight for the most accurate calorie expenditure calculation.

Q4: Can I use this for other exercises?
A: Yes, the formula works for any physical activity. Just use the appropriate MET value for the specific exercise.

Q5: Where can I find MET values for different activities?
A: The Compendium of Physical Activities provides comprehensive MET values for various exercises and activities.
