Calories Burned Equation:
| From: | To: |
The calories burned calculation estimates the energy expenditure of physical activities based on MET values (Metabolic Equivalent of Task), body weight, and duration of the activity. It helps in tracking energy expenditure for fitness and weight management.
The calculator uses the following equation:
Where:
Explanation: The equation calculates calories burned by multiplying the MET value (activity intensity) by body weight and the fraction of time spent (converted from minutes to hours).
Details: MET values represent the intensity of physical activities. One MET is defined as the energy cost of sitting quietly, equivalent to 1 kcal/kg/hour. Higher MET values indicate more intense activities.
Tips: Enter the MET value of your activity, your weight in kilograms, and the duration in minutes. All values must be positive numbers.
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: Is this calculation accurate for everyone?
A: It provides an estimate. Individual variations in metabolism, fitness level, and body composition can affect actual calories burned.
Q3: Should I use my current weight or goal weight?
A: Always use your current weight for accurate calculations as calories burned are directly proportional to body mass.
Q4: How does body composition affect calories burned?
A: Muscle tissue burns more calories than fat tissue at rest, so individuals with higher muscle mass may burn slightly more calories.
Q5: Can I use this for weight loss planning?
A: Yes, this can help estimate calorie expenditure, but remember weight loss also depends on calorie intake and other factors.
