General Calorie Guidelines
Average daily calorie recommendations for children based on public health guidelines (e.g., NHS). Individual needs vary.
| Age Group | Estimated Daily Calories | Key Nutritional Focus |
|---|---|---|
| 3–5 years | 1,200 – 1,400 kcal | Establishing healthy eating habits, varied diet, portion control |
| 6–8 years | 1,400 – 1,600 kcal | Supporting steady growth, school activity, and cognitive development |
| 9–12 years | 1,600 – 2,000 kcal | Pre-puberty growth spurts, active play, calcium and iron intake |
| 13–18 years | 2,000 – 2,800 kcal | Puberty, higher energy needs, especially for active teens and athletes |
Child Nutrition FAQ
Everything you need to know about estimating calorie needs, BMR, and supporting healthy growth.
Calorie needs vary significantly by age, gender, weight, and activity level. As a general guideline, children aged 4-6 need around 1,400 kcal, 7-10 years need 1,600-1,800 kcal, and teenagers can require anywhere from 2,000 to 2,800 kcal daily. This calculator provides a more personalised estimate.
Basal Metabolic Rate (BMR) is the number of calories a child’s body burns at complete rest to maintain vital functions like breathing, circulation, and cell production. It forms the baseline for calculating their Total Daily Energy Expenditure (TDEE).
No, you should never put a child on a restrictive calorie diet without direct supervision from a paediatrician or registered dietitian. Children need adequate energy and nutrients for healthy growth and brain development. Focus instead on offering nutrient-dense whole foods and encouraging regular physical activity.
Activity level significantly impacts Total Daily Energy Expenditure (TDEE). A highly active child who plays sports daily will burn substantially more calories than a sedentary child, requiring a higher caloric intake to support their growth, recovery, and energy levels.
