1. What is the Calorie Calculator?

The Calorie Calculator estimates your daily energy needs based on your Basal Metabolic Rate (BMR) and activity level. It helps determine how many calories you should consume to maintain your current weight.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( BMR \) — Basal Metabolic Rate (calories your body needs at complete rest)
• \( Activity\ Factor \) — Multiplier based on your activity level

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 — Extremely Active (very hard exercise & physical job)

3. Importance of Calorie Calculation

Details: Knowing your daily calorie needs is essential for weight management, whether your goal is to maintain, lose, or gain weight. It provides a scientific basis for meal planning and dietary adjustments.

4. Using the Calculator

Tips: Enter your BMR (use a BMR calculator if unknown) and select your activity level. For accurate results, be honest about your activity level.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between BMR and TDEE?
A: BMR is calories burned at complete rest, while TDEE (Total Daily Energy Expenditure) includes all activities. This calculator estimates TDEE.

Q2: How accurate is this calculator?
A: It provides a good estimate but individual variations exist due to metabolism, body composition, and other factors.

Q3: Should I eat exactly these calories?
A: Use this as a starting point and adjust based on your weight changes and energy levels.

Q4: How often should I recalculate?
A: Recalculate if your weight changes significantly or your activity level changes.

Q5: Can I use this for weight loss?
A: Yes, subtract 300-500 calories from the result for moderate weight loss (0.5-1 lb/week).
