1. What is Daily Calories Burned?

Daily calories burned (Daily_burn) represents the total number of calories your body uses in a day, including your basal metabolic rate (BMR) and calories burned through physical activity. It's a key metric for weight management and fitness planning.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor equation for BMR and multiplies it by an activity factor:

Where BMR is calculated as:

• For men: \( BMR = (10 \times weight) + (6.25 \times height) - (5 \times age) + 5 \)
• For women: \( BMR = (10 \times weight) + (6.25 \times height) - (5 \times age) - 161 \)

Activity Factors:

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

3. Importance of Calculating Daily Calorie Burn

Details: Knowing your daily calorie burn helps with weight management (loss, gain, or maintenance), fitness planning, and nutritional requirements. It provides a baseline for creating personalized diet and exercise plans.

4. Using the Calculator

Tips: Enter your gender, age in years, weight in kg, height in cm, and select your activity level. For accurate results, be honest about your activity level and use current measurements.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculator?
A: It provides a good estimate for most people, but individual variations in metabolism can affect actual calorie burn.

Q2: Should I eat fewer calories than my daily burn to lose weight?
A: Generally, a 500 kcal/day deficit leads to about 0.5 kg/week weight loss, but consult a professional for personalized advice.

Q3: How often should I recalculate my daily calories burned?
A: Recalculate when your weight changes significantly (5+ kg) or your activity level changes substantially.

Q4: Why use kg and cm instead of pounds and inches?
A: The formula is designed for metric units, but you can convert from imperial if needed (1 kg = 2.2 lbs, 1 inch = 2.54 cm).

Q5: Does this account for body composition?
A: No, the calculator doesn't distinguish between muscle and fat. Those with higher muscle mass may burn more calories than estimated.
