1. What is Daily Calorie Intake?

Daily calorie intake represents the total number of calories your body needs each day to maintain its current weight, accounting for basal metabolic rate, physical activity, and the thermic effect of food.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( BMR \) — Basal Metabolic Rate (calories burned at rest)
• \( Exercise \) — Calories burned through physical activity
• \( TEF \) — Thermic Effect of Food (calories burned digesting food)

Explanation: This formula provides a comprehensive approach to calculating total daily energy expenditure by combining all major components of calorie consumption.

3. Importance of Calorie Intake Calculation

Details: Accurate calorie intake calculation is essential for weight management, athletic performance optimization, and maintaining overall health and energy balance.

4. Using the Calculator

Tips: Enter BMR in kcal, exercise calories in kcal, and TEF in kcal. All values must be valid (BMR > 0, exercise and TEF ≥ 0).

5. Frequently Asked Questions (FAQ)

Q1: How do I calculate my BMR?
A: BMR can be estimated using formulas like Mifflin-St Jeor or Harris-Benedict equations based on age, gender, weight, and height.

Q2: What is a typical TEF value?
A: TEF typically accounts for 10-15% of total daily energy expenditure, varying based on meal composition and frequency.

Q3: How accurate is exercise calorie estimation?
A: Exercise calorie estimates can vary significantly based on intensity, duration, and individual metabolism. Wearable devices can provide more accurate measurements.

Q4: Should this calculation be adjusted for weight goals?
A: Yes, for weight loss subtract 500-1000 kcal/day, for weight gain add 300-500 kcal/day from maintenance level.

Q5: How often should I recalculate my calorie needs?
A: Recalculate every 4-6 weeks or after significant weight changes (±5 kg) or changes in activity level.
