1. What is Daily Caloric Needs Calculation?

Daily caloric needs calculation estimates the number of calories your body requires 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 Mifflin-St Jeor Equation for BMR and activity multipliers:

Where BMR is calculated as:

• For men: \( BMR = 10 \times weight + 6.25 \times height - 5 \times age + 5 \)
• For women: \( BMR = 10 \times weight + 6.25 \times height - 5 \times age - 161 \)

Activity Factors:

• Sedentary (little or no exercise): 1.2
• Lightly active (light exercise 1-3 days/week): 1.375
• Moderately active (moderate exercise 3-5 days/week): 1.55
• Very active (hard exercise 6-7 days/week): 1.725
• Extra active (very hard exercise and physical job): 1.9

3. Importance of Caloric Needs Calculation

Details: Understanding your daily caloric needs is essential for weight management, whether your goal is to lose, maintain, or gain weight. It helps create appropriate diet plans and ensures adequate energy intake for your activity level.

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 positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why use Mifflin-St Jeor Equation instead of others?
A: The Mifflin-St Jeor Equation is considered the most accurate for estimating BMR in healthy individuals and is widely used by health professionals.

Q2: What if I want to lose weight?
A: To lose weight, create a calorie deficit by consuming 300-500 fewer calories than your maintenance needs, combined with regular exercise.

Q3: How often should I recalculate my caloric needs?
A: Recalculate whenever your weight changes significantly (±5 kg) or your activity level changes substantially.

Q4: Are there limitations to this calculation?
A: This calculation provides an estimate and may not account for individual variations in metabolism, body composition, or specific medical conditions.

Q5: Should pregnant or breastfeeding women use this calculator?
A: Pregnant and breastfeeding women have different nutritional needs and should consult with healthcare providers for personalized recommendations.
