1. What is Daily Calorie Intake?

Daily calorie intake represents the number of calories you need to consume each day to maintain your current weight, based on your basal metabolic rate (BMR) and activity level.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( BMR \) — Basal Metabolic Rate (calories burned at rest)
• \( Activity\_factor \) — Multiplier based on activity level

Explanation: The equation accounts for your body's basic energy needs plus additional calories burned through physical activity.

3. Importance of Calorie Calculation

Details: Knowing your daily calorie needs is crucial for weight management, whether you want to maintain, lose, or gain weight.

4. Using the Calculator

Tips: Enter your BMR in kcal/day and select your activity level. For weight loss, consume fewer calories than calculated; for weight gain, consume more.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculation?
A: It provides a good estimate but individual variations exist based on metabolism, body composition, and other factors.

Q2: What if I don't know my BMR?
A: Use a BMR calculator first, which requires age, gender, height and weight.

Q3: Should I adjust my calories for weight goals?
A: Yes, subtract 500 kcal/day for ~1 lb/week weight loss or add 500 kcal/day for ~1 lb/week gain.

Q4: Do activity factors account for exercise?
A: Yes, choose the factor that best matches your regular activity level including exercise.

Q5: How often should I recalculate?
A: Recalculate whenever your weight changes significantly or your activity level changes.
