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

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 to maintain, lose, or gain weight. It provides a scientific basis for meal planning.

4. Using the Calculator

Tips: Enter your BMR (calculated separately) 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 do I calculate my BMR?
A: BMR can be calculated using equations like Mifflin-St Jeor or Harris-Benedict, which consider age, gender, weight, and height.

Q2: Why is activity factor important?
A: It accounts for the additional calories burned through physical activity beyond your basal metabolic rate.

Q3: How accurate is this calculation?
A: It provides a good estimate but individual variations exist. Adjust based on results over time.

Q4: Should I eat exactly the calculated calories?
A: Use it as a starting point. Monitor your weight and adjust as needed based on your goals.

Q5: Does muscle mass affect calorie needs?
A: Yes, more muscle increases BMR as muscle burns more calories at rest than fat.
