How Calorie Needs Are Calculated
This calculator uses the Mifflin-St Jeor equation to estimate Basal Metabolic Rate (BMR) – the calories your body needs at rest. This is then multiplied by an activity factor to determine Total Daily Energy Expenditure (TDEE).
Mifflin-St Jeor Equation
For boys: BMR = 10 × weight(kg) + 6.25 × height(cm) – 5 × age(y) + 5
For girls: BMR = 10 × weight(kg) + 6.25 × height(cm) – 5 × age(y) – 161
The BMR is then multiplied by an activity factor:
- Sedentary (little to no exercise): BMR × 1.2
- Lightly active (light exercise 1-3 days/week): BMR × 1.375
- Moderately active (moderate exercise 3-5 days/week): BMR × 1.55
- Very active (hard exercise 6-7 days/week): BMR × 1.725
- Extra active (very hard exercise and physical job): BMR × 1.9
Pediatric Nutrition Guidelines
Proper nutrition is essential for growth and development in children. Here are some general guidelines:
Protein
Essential for growth and development. Good sources include lean meats, poultry, fish, eggs, dairy products, beans, and nuts.
Carbohydrates
The body’s main source of energy. Focus on whole grains, fruits, vegetables, and legumes rather than refined sugars.
Fats
Important for brain development and vitamin absorption. Choose healthy fats from sources like avocados, nuts, seeds, and olive oil.
Vitamins and Minerals
Ensure adequate intake of calcium for bone development, iron for blood health, and vitamin D for overall growth.
Understanding Activity Levels
Physical activity is crucial for children’s health and development. Here’s how to interpret activity levels:
Sedentary
Little to no exercise, mostly sitting (e.g., watching TV, playing video games, reading)
Lightly Active
Light exercise 1-3 days per week (e.g., walking to school, light play)
Moderately Active
Moderate exercise 3-5 days per week (e.g., physical education classes, biking, swimming)
Very Active
Hard exercise 6-7 days per week (e.g., sports practice, intense play)
Extra Active
Very hard exercise and physical activity (e.g., competitive athletics, intensive training)
The American Academy of Pediatrics recommends at least 60 minutes of physical activity daily for children.
