Calories Burned Formula:
| From: | To: |
The Calories Burned (CB) formula estimates total daily energy expenditure by multiplying Basal Metabolic Rate (BMR) by an Activity Factor (AF). This provides an accurate assessment of how many calories you burn in a day based on your metabolic rate and activity level.
The calculator uses the Calories Burned formula:
Where:
Explanation: The equation calculates total daily energy expenditure by accounting for both your body's baseline metabolic needs and your physical activity level throughout the day.
Details: Accurate calorie burn estimation is crucial for weight management, fitness planning, nutritional guidance, and creating effective diet and exercise programs tailored to individual needs.
Tips: Enter your BMR in kcal and your Activity Factor. BMR can be calculated using various formulas (Harris-Benedict, Mifflin-St Jeor, etc.). Activity Factor typically ranges from 1.2 (sedentary) to 2.5 (very active).
Q1: What is BMR and how is it different from calories burned?
A: BMR (Basal Metabolic Rate) represents the calories your body burns at complete rest, while total calories burned includes all daily activities and exercise.
Q2: How do I determine my Activity Factor?
A: Activity Factor is typically: 1.2 (sedentary), 1.375 (light activity), 1.55 (moderate), 1.725 (very active), or 1.9-2.5 (extremely active/athlete).
Q3: How accurate is this calculation?
A: This provides a good estimate, but individual variations in metabolism, body composition, and activity patterns can affect accuracy.
Q4: Should I use this for weight loss planning?
A: Yes, this calculation helps create appropriate calorie deficits for weight loss while maintaining energy levels and metabolic health.
Q5: How often should I recalculate my calories burned?
A: Recalculate when your weight changes significantly, activity levels change, or every 3-6 months to account for metabolic adaptations.
