How many calories should a 10-year-old eat?

The short answer

Most 10-year-olds need roughly 1,400 to 2,200 calories a day: about 1,400–2,000 for girls and 1,600–2,200 for boys, depending on how active they are. These figures come from the estimated calorie needs table in the 2020–2025 Dietary Guidelines for Americans.¹

In real food, that simply means three meals and two or three snacks a day, which is what the American Academy of Pediatrics suggests for children.⁵ You don’t need to add anything up to get it right.

The Guidelines define the levels this way: sedentary means only the activity of everyday living; moderately active adds the equivalent of walking about 1.5 to 3 miles a day; active means more than 3 miles a day.¹ A child on a sports team most days is usually toward the top of the range.

Which edition is this?

The 2025–2030 Dietary Guidelines, published in January 2026, don’t include a calorie table by age. They say calorie needs depend on age, sex, height, weight and level of physical activity.² So we use the 2020–2025 estimates, which were calculated from average heights and reference weights for each age.¹ Your own child’s needs can sit well above or below them.

What about 11- and 12-year-olds?

Estimated needs creep up each year. By the 2020–2025 figures, an 11-year-old girl needs about 1,600–2,000 calories and a 12-year-old girl 1,600–2,200; an 11-year-old boy about 1,800–2,200 and a 12-year-old boy 1,800–2,400.¹ The Guidelines note that girls generally need less than boys, and that the range widens in adolescence to fit very different growth patterns.¹ A 12-year-old in the middle of a growth spurt may eat more than either parent — and that can be exactly right.

Why counting isn’t the goal

A calorie estimate describes a group of children, not yours. The AAP puts the real test simply: a child who is growing well is getting enough to eat.⁵ Your pediatrician checks that at every visit, using your child’s own growth curve.

The AAP’s advice on how to feed is just as simple: your job is to offer healthy food in sensible portions, and your child’s job is to decide how much to eat.⁵ Children generally eat when they’re hungry and stop when they’re full.⁵

There’s a second reason not to count. The AAP’s clinical report on preventing obesity and eating disorders in adolescents says the focus should be on a healthy lifestyle rather than on weight.⁶ It notes that some teenagers who try to lose weight go on to develop an eating disorder, and it recommends more frequent family meals, no “weight talk” or weight teasing at home, and promoting a healthy body image.⁶⁷ The average age of a child with an eating disorder, per the AAP, is 12.5.⁷

Their hunger is a better guide than any number — your job is to make sure good food is there when it arrives.

Puberty turns the appetite up (at different times)

The biggest change between 9 and 13 isn’t a birthday — it’s puberty. Girls usually begin puberty between 8 and 13,⁹ while 95% of boys start between 9 and 14.¹⁰

The AAP says a surge in appetite around age 10 in girls and 12 in boys signals the coming growth spurt, and that the body demands more calories in early adolescence than at any other time of life.³ Calorie needs rise during times of rapid growth.⁴ That’s why two 11-year-olds in the same class can eat very different amounts, and both be normal.

Weight gain is part of this too. The AAP notes it’s normal for children to gain weight as they grow taller in puberty, and that the overall pattern on the growth chart matters more than any one number.⁹ For what to expect month by month, see our guide to the preteen growth spurt and constant hunger.

Eating more on their own

Preteens make a lot of their own food decisions — the school cafeteria, snacks at a friend’s house, what they grab after practice. The Dietary Guidelines note that independence in food choices grows through these years, with more eating in social settings.¹ You can’t control all of it, and you don’t need to.

Breakfast is one place to watch. The AAP reports that 13% of school-aged children skip breakfast, rising to more than 27% of adolescents aged 12 to 19, and that girls start skipping earlier. Some kids skip it to try to avoid weight gain.¹¹ If your preteen starts skipping meals, it’s worth a gentle conversation.

When to talk to your pediatrician

These signs are drawn from the National Institute of Mental Health and the AAP.⁸⁷ The AAP also notes that some eating disorders start as increasingly strict rules about the kind of food eaten rather than the amount.⁷ The earlier an eating disorder is found, the better the chance of a healthy outcome.⁷
