1. What is the Calories Burned Formula?

The calories burned formula estimates energy expenditure based on MET (Metabolic Equivalent of Task) value, activity duration, and body weight (fixed at 200 lbs in this calculator).

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( MET \) — Metabolic Equivalent of Task (dimensionless)
• \( 90.718 \) — Conversion factor for 200 lbs (90.718 kg)
• \( time \) — Activity duration in minutes

Explanation: The formula accounts for the intensity of activity (MET), duration, and body weight to estimate calories burned.

3. Importance of MET Values

Details: MET values represent the energy cost of physical activities. One MET is the energy expended at rest (sitting quietly). Higher MET values indicate more intense activities.

4. Using the Calculator

Tips: Enter valid MET value (typically 1-12 for most activities) and duration in minutes. Common MET values: walking=3.5, running=8, cycling=6-8, swimming=6-11.

5. Frequently Asked Questions (FAQ)

Q1: Why is the weight fixed at 200 lbs?
A: This calculator is specifically designed for individuals weighing 200 lbs. For other weights, a different calculator would be needed.

Q2: Where can I find MET values for activities?
A: The Compendium of Physical Activities provides comprehensive MET values for hundreds of activities.

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

Q4: Does this account for afterburn effect?
A: No, this calculation only estimates calories burned during the activity, not the additional calories burned afterward.

Q5: Can I use this for weight loss planning?
A: Yes, but remember that dietary changes typically have a greater impact on weight loss than exercise alone.
