1. What is Daily Calorie Intake Calculation?

Daily calorie intake calculation estimates the number of calories your body needs each day to maintain your current weight based on your Basal Metabolic Rate (BMR) and activity level. This is essential for weight management and maintaining a healthy lifestyle.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( BMR \) — Basal Metabolic Rate calculated using Mifflin-St Jeor Equation
• \( Activity \) — Activity multiplier based on your daily physical activity level

BMR Calculation:
For men: BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age(y) + 5
For women: BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age(y) - 161

3. Importance of Calorie Calculation

Details: Understanding your daily calorie needs is crucial for weight management, athletic performance, and overall health. It helps in creating personalized diet plans and achieving fitness goals.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, age in years, select gender and activity level. All values must be valid (weight > 0, height > 0, age between 1-120).

5. Frequently Asked Questions (FAQ)

Q1: What is BMR?
A: Basal Metabolic Rate (BMR) is the number of calories your body needs to perform basic life-sustaining functions at rest.

Q2: How accurate is this calculation?
A: The Mifflin-St Jeor equation is considered one of the most accurate BMR formulas for the general population.

Q3: Should I eat more or less than my calculated calories?
A: To maintain weight, eat at your calculated level. To lose weight, create a calorie deficit. To gain weight, create a calorie surplus.

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

Q5: Are there any limitations to this calculation?
A: This calculation provides an estimate. Individual variations in metabolism, muscle mass, and other factors may affect actual calorie needs.
