Quick answer: Most health experts recommend that 12 year olds eat 3 meals and 2-3 small snacks per day. This provides enough calories and nutrients to support growth and development at this age.
How many calories does a 12 year old need?
The number of calories a 12 year old needs depends on their height, weight, and activity level. On average, adolescent boys need 2,000-3,200 calories per day, while adolescent girls need 1,800-2,400 calories per day.
According to the Dietary Guidelines for Americans, the recommended calorie intake for 12 year olds is:
| Gender | Sedentary | Moderately Active | Active |
|---|---|---|---|
| Boys | 1,800 calories | 2,000-2,200 calories | 2,000-2,600 calories |
| Girls | 1,600 calories | 1,800 calories | 1,800-2,200 calories |
These recommended calorie intakes are estimates that will need to be adjusted up or down depending on the child’s individual energy needs.
Key nutrients for 12 year olds
In addition to calories, 12 year olds have increased needs for certain vitamins and minerals to support growth and development:
- Calcium: 1300 mg per day is recommended to build strong bones and teeth.
- Vitamin D: 600 IU per day helps calcium absorption for bone health.
- Iron: 8-12 mg per day prevents iron deficiency and anemia.
- Vitamin A: 600 mcg per day for vision, immune function, and cell growth.
- Vitamin C: 45 mg per day for wound healing, immune defenses, and iron absorption.
Getting enough protein is also important at this age, with recommended intake of 34 grams per day for boys and 46 grams per day for girls.
How often should a 12 year old eat?
Most experts recommend 3 meals and 2-3 small snacks per day for 12 year olds. This meal pattern provides enough calories for growth and includes nutrients that get absorbed best when eaten at regular intervals.
Here is an example meal plan with 3 meals and 2 snacks:
- Breakfast: Oatmeal with fruit and milk, whole wheat toast with peanut butter, glass of juice
- Mid-morning snack: Yogurt and granola bar
- Lunch: Turkey sandwich on whole grain bread, carrots and celery with ranch dip, apple
- Afternoon snack: String cheese and whole grain crackers
- Dinner: Baked chicken, brown rice, green beans, milk
Snacks should be nourishing, such as yogurt, fruit, vegetables, cheese, nuts, or whole grain snacks. Sweets and desserts should be occasional treats rather than daily snacks.
Breakfast
Breakfast is important for jumpstarting metabolism and providing energy and focus for the day. Some healthy breakfast choices include:
- Whole grain cereal or oatmeal with milk and fruit
- Whole wheat toast with peanut butter or low-fat cheese
- Egg sandwich on whole grain bread

- Whole wheat pasta with meat sauce and side salad
- Vegetarian chili with whole grain cornbread

Snacks
In addition to the 3 main meals, most 12 year olds need 2-3 snacks per day. Healthy snack ideas include:

- Yogurt or cottage cheese
- String cheese or Greek yogurt dip
- Nut butter on whole grain toast or crackers

Having nourishing snacks during the day helps kids get all the nutrients and calories they need to grow. Just watch portion sizes to prevent overeating between meals.
How meal timing affects health
In addition to eating the right foods, the timing of meals can impact health:
- Eating breakfast helps increase concentration, problem-solving, and academic performance.
- Spacing meals 4-5 hours apart keeps metabolism and energy levels steady.
- Not eating 3-4 hours before bedtime helps prevent indigestion and sleep issues.
- Eating more earlier in the day and less in the evening may aid weight management.
Aim to eat breakfast within 1 hour of waking up, have the biggest meal earlier in the day, and avoid big meals within a couple hours of bedtime.
Tips for healthy eating habits
Here are some tips to encourage healthy eating habits in 12 year olds:
- Involve kids in meal planning and preparation
- Serve balanced meals with lean protein, whole grains, veggies, and fruit
- Role model healthy choices instead of dieting
- Make water the primary drink instead of sugary drinks
- Limit fast food and eat home cooked meals as a family
- Allow occasional treats in moderation
- Take kids grocery shopping to make healthier choices
Common questions
Is it normal for a 12 year old to skip breakfast?
Skipping breakfast becomes more common at this age, but it is not recommended. Breakfast skippers may lack focus at school and tend to overeat later. A quick grab-and-go breakfast is better than nothing.
Should a 12 year old take a multivitamin?
A daily multivitamin can help fill any nutritional gaps in the diet, especially picky eaters. Check with your pediatrician to see if a children’s multivitamin is recommended.
How can I get more vegetables into my 12 year old’s diet?
Try disguising veggies in foods they already eat like pizza, pasta, tacos, smoothies etc. Offer choices and let them pick out new veggies at the store. Lead by example and increase your own veggie intake.
The bottom line
- 12 year olds should eat about 3 meals and 2-3 snacks per day
- Aim for regular meal timing and include breakfast daily
- Choose balanced meals with lean protein, fruits, vegetables and whole grains
