MathChild Calorie Calculator
Calculate daily calorie needs for children and teens. Determine recommended calories, macros, and nutrition requirements based on age, activity level, and goals.
Little or no exercise, mostly sitting (school, homework, screen time)
Light exercise or sports 1-3 days per week (PE class, casual play)
Moderate exercise or sports 3-5 days per week (team sports, regular training)
Hard exercise or sports 6-7 days per week (competitive sports, daily practice)
Very hard exercise daily, physical job, or training twice per day
What are Calorie Needs for Children?
Children have unique nutritional needs that change as they grow. Their calorie requirements depend on age, gender, size, and activity level. Meeting these needs is essential for proper growth, development, and energy throughout the day.
This calculator uses the Schofield equation, which is specifically designed for calculating energy requirements in children and adolescents.
Factors Affecting Calorie Needs
- Age: Calorie needs increase through childhood and peak during adolescence
- Gender: Boys typically need more calories than girls, especially during puberty
- Growth rate: Rapid growth periods require more energy
- Activity level: More active children need more calories
- Body composition: Muscle requires more energy than fat tissue
Understanding Macronutrients for Children
A balanced diet for children should include appropriate amounts of:
- Protein (15-20%): Essential for growth, muscle development, and immune function. Sources: lean meats, fish, eggs, dairy, legumes
- Carbohydrates (50-60%): Primary energy source for active children. Focus on whole grains, fruits, vegetables
- Fats (25-30%): Important for brain development and hormone production. Choose healthy fats from nuts, fish, avocados, olive oil
Tips for Healthy Eating in Children
- Focus on whole, nutrient-dense foods rather than just calories
- Ensure adequate fruits and vegetables (5+ servings daily)
- Choose whole grains over refined grains
- Limit added sugars and processed foods
- Ensure adequate hydration with water
- Encourage regular meal times and family meals
- Avoid restrictive diets unless medically necessary
- Promote a positive relationship with food
