1. What is Activity Calorie Burn?

Activity calorie burn refers to the number of calories expended during physical exercise or activity. It is calculated using the MET (Metabolic Equivalent of Task) system, which measures the energy cost of physical activities.

2. How Does the Calculator Work?

The calculator uses the standard calorie burn formula:

Where:

• \( MET \) — Metabolic Equivalent of Task
• \( Weight_{kg} \) — Body weight in kilograms
• \( Time_h \) — Duration of activity in hours

Explanation: MET values represent the ratio of working metabolic rate to resting metabolic rate. One MET is defined as the energy cost of sitting quietly.

3. Importance of Calorie Tracking

Details: Tracking calorie expenditure helps in weight management, fitness planning, and understanding the energy demands of different activities for optimal health and performance.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What are MET values?
A: MET (Metabolic Equivalent of Task) is a unit that estimates the energy cost of physical activities. 1 MET equals the energy expended while sitting at rest.

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

Q3: Where can I find MET values for different activities?
A: MET values are available in compendiums of physical activities published by health organizations and research institutions.

Q4: Does this account for after-burn effect?
A: No, this calculation only estimates calories burned during the activity itself and does not include excess post-exercise oxygen consumption (EPOC).

Q5: Can I use this for weight loss planning?
A: Yes, this calculator can help estimate calorie deficit when combined with dietary intake tracking for weight management goals.
