1. What is Daily Calorie Intake?

Daily calorie intake represents 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 calculation is essential for weight management and nutritional planning.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor Equation for BMR:

\[ BMR = (10 \times weight) + (6.25 \times height) - (5 \times age) + 5 \text{ (for men)} \] \[ BMR = (10 \times weight) + (6.25 \times height) - (5 \times age) - 161 \text{ (for women)} \]

Then calculates daily calories:

\[ Daily Calories = BMR \times Activity Factor \]

Where Activity Factor is:

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: Understanding your daily calorie needs is crucial for weight management, whether your goal is to lose, maintain, or gain weight. It helps create appropriate meal plans and ensures you're meeting your nutritional requirements.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why is this calculator specific to India?
A: While the calculation method is universal, this calculator is tailored with Indian dietary considerations and average body metrics in mind.

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, with an accuracy of about ±10%.

Q3: Should I eat fewer calories to lose weight?
A: For weight loss, a deficit of 500-750 calories per day from your maintenance level is generally recommended for sustainable weight loss of 0.5-1kg per week.

Q4: Do calorie needs change with age?
A: Yes, metabolic rate typically decreases with age, which is accounted for in the BMR calculation through the age component.

Q5: How often should I recalculate my calorie needs?
A: Recalculate whenever your weight changes significantly (±5kg), your activity level changes substantially, or every 6-12 months as part of regular health assessment.
