Calories Burned Formula:
| From: | To: |
The Calories Burned Doing Nothing Calculator estimates the number of calories your body burns at complete rest based on your Basal Metabolic Rate (BMR) and the duration of rest. This represents the energy your body needs to maintain basic physiological functions.
The calculator uses the formula:
Where:
Explanation: This calculation divides your daily BMR by 24 to get your hourly resting metabolic rate, then multiplies by the number of hours to determine total calories burned during that period.
Details: Understanding your resting calorie expenditure helps with weight management, nutrition planning, and establishing appropriate calorie intake goals for maintaining, losing, or gaining weight.
Tips: Enter your BMR in kcal/day and the duration in hours. Both values must be positive numbers. For accurate results, use a recently calculated BMR value.
Q1: What is BMR?
A: Basal Metabolic Rate (BMR) is the number of calories your body needs to perform basic life-sustaining functions at complete rest.
Q2: How is BMR different from TDEE?
A: BMR represents calories burned at complete rest, while TDEE (Total Daily Energy Expenditure) includes all activities and represents your total daily calorie burn.
Q3: How often should I recalculate my BMR?
A: Your BMR changes with weight, age, and body composition. Recalculate every 2-3 months or after significant weight changes (±5kg).
Q4: Does this calculation account for sleep?
A: Yes, this calculation works for any period of rest, including sleep. Your metabolic rate during sleep is typically slightly lower than your true BMR.
Q5: Can I use this for weight loss planning?
A: Yes, understanding your resting calorie expenditure helps create accurate calorie deficits for weight loss while ensuring you meet your body's basic energy needs.
