1. What is the Calorie Expenditure Equation?

The calorie expenditure equation estimates total calories burned during physical activity based on MET value, body weight, session duration, and number of sessions. It provides a practical way to quantify energy expenditure for walking programs.

2. How Does the Calculator Work?

The calculator uses the calorie expenditure equation:

Where:

• \( MET \) — Metabolic equivalent of task (3.0 for moderate walking)
• \( Weight_{kg} \) — Body weight in kilograms
• \( Time_{hours} \) — Duration of each session in hours
• \( Sessions \) — Number of exercise sessions

Explanation: The equation multiplies the metabolic cost (MET) by body weight and total exercise time to estimate energy expenditure.

3. Importance of Calorie Calculation

Details: Accurate calorie estimation helps in weight management, exercise prescription, and monitoring energy balance in fitness programs.

4. Using the Calculator

Tips: Enter MET value (3.0 for walking), weight in kg, session time in hours, and number of sessions. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a MET value?
A: MET (Metabolic Equivalent of Task) represents exercise intensity. 1 MET = resting energy expenditure. Walking typically ranges from 2.5-4.3 METs depending on speed.

Q2: How accurate is this calculation?
A: It provides a reasonable estimate for general purposes, but individual variations in metabolism can affect actual calorie expenditure.

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

Q4: What's a typical MET value for walking?
A: Brisk walking (3-4 mph) is about 3.5-4.3 METs, while slow walking is 2.0-2.5 METs.

Q5: Can I use this for other exercises?
A: Yes, with appropriate MET values. Running (6-10 METs), cycling (4-8 METs), etc.
