1. What is Daily Calorie Intake?

Daily calorie intake represents the total number of calories your body needs each day to maintain, gain, or lose weight based on your goals. It's calculated using your basal metabolic rate (BMR), activity level, and desired calorie deficit or surplus.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( BMR \) — Basal Metabolic Rate: Calories burned at complete rest
• \( Activity \) — Additional calories burned through physical activity
• \( Deficit \) — Calorie reduction for weight loss goals

Explanation: This formula helps determine your optimal daily calorie intake based on your metabolism, activity level, and weight management objectives.

3. Importance of Calorie Intake Calculation

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

4. Using the Calculator

Tips: Enter your BMR in kcal, estimated activity calories burned, and desired calorie deficit. All values must be valid positive numbers for accurate results.

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, height, and weight.

Q2: What's a healthy calorie deficit for weight loss?
A: A deficit of 500-1000 calories per day typically results in safe weight loss of 0.5-1 kg per week.

Q3: Should activity calories include exercise only?
A: Activity calories should include all physical movement beyond basal metabolic rate, including exercise, daily activities, and NEAT (non-exercise activity thermogenesis).

Q4: How often should I recalculate my calorie intake?
A: Recalculate every 4-6 weeks or when your weight, activity level, or goals change significantly.

Q5: Is this calculation accurate for everyone?
A: While generally accurate, individual variations in metabolism may require adjustments based on actual results and progress.
