Dieting can stunt growth in children and teenagers if it leads to malnutrition or a severe calorie deficit. Malnutrition can cause a lack of energy and stunt growth, as the body may not be able to develop fully without the right combination of vitamins and minerals. Restricting calories too severely can also negatively impact growth, as can drastic weight loss. However, replacing unhealthy diet patterns with healthier choices and incorporating exercise can help children and teens achieve a healthy weight without stunting their growth.

Malnutrition and stunted growth
Malnutrition refers to deficiencies, excesses, or imbalances in a person's intake of energy and/or nutrients. It includes undernutrition (wasting, stunting, and underweight), inadequate vitamins or minerals, overweight, obesity, and resulting diet-related noncommunicable diseases. Undernutrition, which includes stunting, is a condition where a person's height-for-age is below the median standards. Stunting indicates chronic malnutrition, and its effects are largely irreversible. It is often a result of insufficient calorie intake and/or infectious diseases.
In 2022, an estimated 149 million children under the age of five were suffering from stunting, with nearly half of the deaths among children under five linked to undernutrition. The developmental, economic, social, and medical impacts of malnutrition are serious and lasting, and people who experience stunting in childhood may also experience worse cognitive development, which can lead to worse economic outcomes as adults.
Stunting can be caused by a lack of sufficient calories or specific nutrients, such as protein, amino acids, and individual amino acids like lysine and arginine, which are linked to growth hormone release in young children. Even a transient reduction in calorie or protein availability can result in a reduction in insulin-like growth factor 1 (IGF-1) synthesis, leading to potential growth issues.
While malnutrition can affect people of all ages, women, infants, children, and adolescents are at particular risk. Optimizing nutrition early in life, including the 1000 days from conception to a child's second birthday, is crucial for ensuring the best possible start, with long-term benefits. Proper nutrition during this critical window can help prevent stunting and wasting, which are indicators of malnutrition.

Calorie requirements for teens
Adolescence is the last opportunity for parents to influence their children to develop healthy eating habits that will benefit them throughout their lives. Despite the abundant food supply in the United States, most adolescents do not receive adequate nutrition when their bodies are rapidly growing and developing. Adolescent diets tend to include too much fat, sugar, caffeine, and sodium, and not enough nutrient-dense foods such as fresh fruits, vegetables, and calcium-rich foods. Their diets also lack adequate fiber.
Some teens eat more calories than their bodies require and become obese, while others obsess about gaining weight and restrict their food intake too severely, becoming dangerously underweight. Restricting calories too severely is not advised since too few calories can have a negative effect and stunt growth. The healthiest way to control a child's weight is to serve them meals with enough—but not too many—calories for normal growth and activities. Exercise is another way to control weight. Encourage your child to be more active and get involved in sports and other active games, as well as limit TV and video games.
Caloric requirements vary according to age, sex, activity level, and genetics, which establish the body's metabolism (the rate at which the body burns calories). In general, guys need to eat more than girls during adolescence, and more active youth need to eat more than less active youth. As a rule of thumb, teens who get less than 30 minutes of vigorous exercise a day are considered sedentary, those who exercise 30 to 60 minutes a day are considered moderately active, and those who get more than an hour of exercise each day are considered active.
For adolescent males, the daily number of calories required for optimal health gradually increases by about 200 calories every one to two years during early adolescence, peaks during middle adolescence, and then decreases by approximately 200 calories in late adolescence. For example, sedentary 12-year-old males need about 1800 calories each day, while sedentary males' daily recommended caloric intake peaks at 2600 calories around age 19-20 years old.
In addition to calories, it is important for teens to get enough calcium and iron in their diets, as these minerals are needed for growing bones and muscles during a teenager's growth spurt. Low iron levels can be especially problematic for girls due to their menstrual flow. To increase iron intake, include iron-rich foods such as red meat, poultry, shellfish, eggs, dark leafy vegetables, and fortified grains in your teen's diet. When serving plant sources of iron, also serve foods high in vitamin C such as orange juice to increase the amount of iron your teen's body will absorb.

Vitamins and minerals for growth
Dieting will only stunt a person's growth if it is severely restrictive and leads to malnutrition. Malnutrition can cause a person to be shorter in stature, as they are unable to reach their full growth potential. However, this does not alter their genetics.
Vitamins and minerals are essential nutrients that the body requires in small amounts to function properly and stay healthy. A healthy, balanced diet should provide all the necessary vitamins and minerals for the body to work as it should.
Calcium
Calcium is the most abundant mineral in the body and is essential for building strong bones and teeth. It also plays a role in regulating heart rhythm and ensuring normal blood clotting. Dairy products, such as milk, are good sources of calcium.
Iron
Iron is crucial for growing bones and muscles during growth spurts. Iron-rich foods include red meat, poultry, shellfish, eggs, dark leafy vegetables, and fortified grains. Vitamin C aids in the absorption of iron, so it is beneficial to pair plant sources of iron with foods high in vitamin C, like orange juice.
Zinc
Zinc is a mineral that supports growth, wound healing, and immune system function. Toddlers and children on vegan or vegetarian diets are at a higher risk of zinc deficiency, which can slow down growth.
Folic Acid (Folate)
Folic acid, or folate, works with vitamin B12 to produce healthy red blood cells and prevent certain birth defects. It also aids in protein absorption and the formation of new blood cells and DNA. Breads, wholegrain foods, and breakfast cereals are often fortified with folic acid.
Vitamin D
Vitamin D is important for bone health, and a deficiency can lead to rickets, delayed motor development, muscle weakness, and bone disease.

Low-glycemic meals for healthy weight
Dieting will only stunt a person's growth if it is severely restrictive, leading to malnutrition. It is important to ensure that a growing child receives enough calories and nutrients to support their development. Therefore, it is recommended to serve meals that provide sufficient calories and essential nutrients like calcium and iron.
Chicken Salad
Try a chicken salad with light mayo, chopped apples, celery, and pecans. Chicken is a good source of protein, and when paired with low-calorie vegetables, it can be a nutritious and filling meal.
Chili
Chili is a simple and versatile dish that can be made in a slow cooker. Use beans, such as chickpeas and kidney beans, which are low on the glycemic index, along with diced tomatoes and crushed tomatoes. You can also add sautéed vegetables like garlic, onions, carrots, celery, and green peppers for extra nutrition.
Veggie Stir-Fry with Brown Rice
Sauté your choice of vegetables in olive or canola oil and serve them over brown rice, which has a lower glycemic index than white rice. You can also add an egg or some meat, such as chicken, pork, or shrimp, for extra protein.
Sweet Potato Hash with Vegetables and Sausage
This dish is a tasty and simple option for breakfast, lunch, or dinner. Sweet potatoes are a good source of complex carbohydrates and can be paired with a variety of vegetables and a moderate amount of sausage for flavor.
Low-GI Breads
When making sandwiches or toast, opt for sprouted bread or sourdough bread, as these have been shown to be more effective in lowering the glycemic response compared to other types of bread.
Soups
Make a large pot of vegetable-based soup, such as cauliflower and leek soup, and freeze individual portions for easy meals. Aim for soups that are heavy on low-carb, low-starch vegetables like carrots and peppers. Clear broth-based soups are also a good option.

Iron and calcium for growing teens
Dieting will only stunt a teenager's growth if it is overly restrictive and leads to malnutrition. However, it is important to note that teens have unique nutritional requirements due to their growth spurts, and a well-rounded diet is essential to support their development.
Iron and calcium are two critical minerals for growing teens. During adolescence, the body undergoes rapid changes, and adequate nutrition is necessary to support bone and muscle development.
Iron for Teens
Iron is essential for several bodily functions. It helps the blood carry oxygen to the lungs, muscles, and all parts of the body. Iron also plays a role in brain function and a healthy immune system. As teens experience growth spurts, their muscle mass increases, and blood volume expands, leading to an increased need for iron. The recommended daily iron intake for females aged 14-18 is 15 milligrams, while for males of the same age, it is 11 milligrams.
Iron-rich foods include red meat, poultry, shellfish, eggs, dark leafy vegetables, and fortified grains. When serving plant-based sources of iron, it is beneficial to include foods high in vitamin C, such as orange juice, to enhance iron absorption.
Calcium for Teens
Calcium is a mineral that builds strong bones and keeps nerves and muscles healthy. It also plays a role in heart health. Adolescence is the only chance to build strong bones, and those who get enough calcium during their teen years will have stronger bones as adults, reducing the risk of fractures and osteoporosis later in life.
The recommended daily calcium intake for teens aged 9-18 is 1300 mg, or roughly four servings of calcium-rich foods. Dairy products like milk, yogurt, and cheese are excellent sources of calcium. For those who are lactose intolerant or follow a vegan diet, non-dairy sources of calcium include dark green leafy vegetables (such as broccoli, kale, and cabbage), tofu, and calcium-fortified juices or plant-based milk alternatives.
In conclusion, while dieting itself may not directly stunt a teen's growth, it is crucial to ensure that any dietary choices or restrictions do not lead to malnutrition or deficiencies in critical nutrients like iron and calcium, which are essential for healthy development during the teenage years.
