1. What is the Daily Calorie Calculator?

The Daily Calorie Calculator estimates your total daily energy expenditure (TDEE) by multiplying your Basal Metabolic Rate (BMR) by an activity factor that represents your physical activity level.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( BMR \) — Basal Metabolic Rate (kcal/day)
• \( Activity\ Factor \) — Multiplier based on 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 — Extra active (very hard exercise & physical job)

3. Importance of Calorie Calculation

Details: Knowing your daily calorie needs helps with weight management, whether your goal is weight loss, maintenance, or gain. It provides a scientific basis for planning your diet.

4. Using the Calculator

Tips: Enter your BMR in kcal/day (from another calculator or test) and select your activity level. The calculator will estimate your total daily calorie needs.

5. Frequently Asked Questions (FAQ)

Q1: What is BMR?
A: Basal Metabolic Rate is the number of calories your body needs at complete rest to maintain basic functions like breathing and circulation.

Q2: How accurate is this calculation?
A: It provides a good estimate but individual variations exist. Factors like muscle mass, genetics, and exact activity levels affect actual needs.

Q3: Should I eat exactly this many calories?
A: Use this as a starting point and adjust based on your goals and how your body responds over time.

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

Q5: Can I use this for weight loss?
A: Yes, subtract 250-500 kcal/day from this number for gradual weight loss (about 0.5-1 lb/week).
