1. What is Daily Calories Burned?

The total daily calories burned represents the sum of your Basal Metabolic Rate (BMR) and calories burned through physical activity. BMR is the number of calories your body needs to maintain basic physiological functions at rest.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor Equation for BMR and activity multipliers:

\[ Calories = BMR \times Activity\ Multiplier \]

Where BMR is calculated as:

\[ Male:\ BMR = (10 \times weight\ in\ kg) + (6.25 \times height\ in\ cm) - (5 \times age\ in\ years) + 5 \] \[ Female:\ BMR = (10 \times weight\ in\ kg) + (6.25 \times height\ in\ cm) - (5 \times age\ in\ years) - 161 \]

Activity multipliers:

Sedentary: 1.2 (little or no exercise)
Lightly active: 1.375 (light exercise 1-3 days/week)
Moderately active: 1.55 (moderate exercise 3-5 days/week)
Very active: 1.725 (hard exercise 6-7 days/week)
Extra active: 1.9 (very hard exercise & physical job)

3. Importance of Calorie Calculation

Details: Knowing your daily calorie expenditure helps with weight management, whether your goal is weight loss, maintenance, or gain. It provides a scientific basis for planning your diet and exercise regimen.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, age in years, select gender and activity level. For accurate results, measure your weight and height precisely.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculator?
A: The Mifflin-St Jeor Equation is considered the most accurate BMR formula for healthy adults, with about ±10% accuracy for most people.

Q2: Why does BMR decrease with age?
A: Muscle mass typically decreases with age, and muscle tissue burns more calories at rest than fat tissue.

Q3: Should I use this if I'm overweight or obese?
A: The equation works reasonably well for overweight individuals, but may slightly overestimate BMR for obese individuals.

Q4: How often should I recalculate my calories?
A: Recalculate whenever your weight changes significantly (5+ kg) or your activity level changes substantially.

Q5: What's the difference between BMR and TDEE?
A: BMR is calories burned at complete rest, while TDEE (Total Daily Energy Expenditure) includes all activity and is what this calculator shows as "Total Daily Calories Burned".
