1. What is the Calories Burned Equation?

The Calories Burned equation estimates your total daily energy expenditure (TDEE) by combining your basal metabolic rate (BMR) with your activity level and additional exercise calories. This helps determine how many calories you burn in a day.

2. How Does the Calculator Work?

The calculator uses the following equation:

\[ \text{Calories Burned} = \text{BMR} \times \text{activity\_factor} + \text{exercise\_calories} \]

Where:

\( BMR \) — Basal Metabolic Rate (calories burned at rest)
\( activity\_factor \) — Multiplier based on activity level (1.2-1.9)
\( exercise\_calories \) — Additional calories burned through exercise

Explanation: The equation accounts for your base metabolism plus additional calories burned through daily activities and exercise.

3. Importance of Calorie and Macro Tracking

Details: Tracking calories and macronutrients (protein, fats, carbs) is essential for achieving fitness goals whether it's weight loss, muscle gain, or maintenance. Proper macro ratios support optimal body composition and performance.

4. Using the Calculator

Tips: Enter your BMR (use a BMR calculator if unknown), select your activity level, input additional exercise calories, and choose your goal. The calculator will suggest appropriate calorie intake and macronutrient distribution.

5. Frequently Asked Questions (FAQ)

Q1: How do I find my BMR?
A: Use a BMR calculator that considers your age, gender, weight, and height. Many online calculators are available.

Q2: What activity factor should I choose?
A: Sedentary (little/no exercise), Lightly Active (light exercise 1-3 days/week), Moderately Active (moderate exercise 3-5 days/week), Very Active (hard exercise 6-7 days/week), Extra Active (very hard exercise & physical job).

Q3: Should I include all exercise calories?
A: Only include intentional exercise beyond your normal daily activities. Wearable trackers can help estimate these.

Q4: Why are the macro ratios different for each goal?
A: Weight loss benefits from higher protein to preserve muscle, muscle gain requires more protein for growth, and maintenance uses balanced ratios.

Q5: How accurate is this calculation?
A: It provides a good estimate but individual variations exist. Adjust based on your results over time.
