Keto For Teens: Is It Safe Or Not?

The ketogenic diet is a popular, low-carb, high-fat diet that has been used to treat epilepsy and brain cancer in children and adolescents. While it can be effective for weight loss, it is not recommended for teens as it restricts essential food groups and can cause side effects such as constipation, lethargy, and nutritional deficiencies. Dietitians suggest that the keto diet is not a balanced option for teens, as it may not provide all the nutrients required for growth and development. Instead, they recommend encouraging healthy lifestyle choices and techniques over quick-fix weight-loss schemes.

Keto can affect mental health and concentration

The keto diet is a high-fat, very low-carb diet, which also includes moderate amounts of protein. The diet aims to put the body into a state of ketosis, where the body uses fat as an energy source and produces a substance called ketone bodies. While the keto diet has been shown to be an effective way to lower the risk of disease and lose weight, it can also have an impact on mental health and concentration.

Nutritional deficiencies

The keto diet can lead to nutritional deficiencies, as it restricts the intake of certain food groups that are essential for growth and development. These include dairy, fruits, and grains, which provide important nutrients such as vitamin D, calcium, dietary fiber, vitamin C, and potassium. Nutritional deficiencies can affect mental health and concentration by impacting the production of neurotransmitters and leading to conditions such as depression.

Initial side effects

When the body first enters ketosis, individuals may experience side effects such as constipation, lethargy, and a lack of energy. These side effects can impact mental health and concentration, making it difficult for individuals to focus and feel motivated.

Impact on the brain

The keto diet has been shown to have an impact on the brain, particularly in individuals with serious mental illnesses such as schizophrenia or bipolar disorder. The diet has been found to improve energy levels, sleep, mood, and quality of life in these individuals. Additionally, the keto diet has been found to reduce the symptoms of anxiety and depression in some people.

Alternative fuel for the brain

The keto diet provides an alternative fuel for the brain in the form of ketones. This can improve the metabolism of the brain and reduce excitability, which may be beneficial for individuals with neurological disorders.

Long-term effects

The long-term effects of the keto diet on mental health and concentration are still being studied. However, it is important to note that the keto diet should only be followed for a maximum of 12 months due to the potential for adverse physical and mental health effects.

It can cause nutritional deficiencies

The keto diet is not recommended for weight loss in children and teenagers because it seriously limits carbohydrates, and young people need carbs to be mentally and physically active. A healthy, well-balanced diet for children and teenagers should include a range of food groups to ensure they get the nutrients they need to grow and develop.

The keto diet removes three of the five food groups that have essential vitamins and minerals: dairy, fruits, and grains. This can lead to nutritional deficiencies, which can have serious health consequences.

For example, a diet low in calcium can lead to a higher risk of kidney stones and lower bone density. Calcium-rich foods such as fruits, vegetables, dairy, and enriched grains are limited on the keto diet.

Similarly, magnesium is important for energy production and nerve and brain function, and a deficiency can lead to muscle cramps, headaches, anxiety, nervousness, and constipation. The keto diet may result in lower magnesium levels due to reduced intake of magnesium-rich foods such as fruits and grains.

Iron is another nutrient that may be lacking in the keto diet, as absorption can be reduced by high amounts of fat. Iron is needed for energy production and making red blood cells, and a deficiency can cause fatigue and trouble breathing during exercise.

Overall, while the keto diet may be effective for weight loss in adults, it can cause nutritional deficiencies in teenagers, which can impact their growth, development, and overall health.

Keto is not a balanced diet for teens

The ketogenic diet is a very-low-carb, high-fat diet that has been shown to deliver several health benefits. However, it is not a balanced diet for teens and can be detrimental to their health and development. Here are some reasons why keto is not suitable for teenagers:

Nutritional deficiencies

Keto removes three of the five food groups that are essential sources of vitamins and minerals for teens. By cutting out carbs, teens will miss out on dairy, fruits, and grains. Dairy provides vitamin D and calcium, which are crucial for bone development and growth. Fruits are rich in dietary fiber, vitamin C, and potassium, while grains fuel brain development and provide energy for teens to grow, play, and exercise. The keto diet can also result in vitamin and mineral deficiencies, affecting the overall health and well-being of teenagers.

Unhealthy relationship with food

The keto diet is considered a fad diet that promotes quick weight loss. Restricting certain food groups and focusing on weight loss can lead to an unhealthy relationship with food. Dietitian Lona Sandon emphasizes that "having teens on a keto diet does not instill a healthy relationship with food." Instead of vilifying specific foods or food groups, teens should be encouraged to eat a variety of nutritious foods and develop a positive relationship with food.

Growth and development

Adequate nutrition is vital during the growth and development phase of adolescence. The keto diet may impact their growth due to its restrictive nature and limited nutrient intake. Carbohydrates are an essential source of energy, and teens on a healthy diet should consume about 130 grams of carbohydrates per day. The keto diet restricts carbs to around 20-30 grams per day, which is insufficient for the energy needs of growing teenagers.

Side effects

The keto diet can cause side effects such as constipation, lethargy, electrolyte imbalance, digestive issues, and elevated blood cholesterol levels. These side effects can be uncomfortable and impact the overall well-being of teens.

Alternative approaches

Instead of restrictive diets like keto, teens should focus on establishing healthy habits and making nutritious food choices. This includes eating a well-balanced diet with a variety of food groups, limiting processed foods and added sugars, choosing nutritious snacks, and staying positive about their relationship with food. It is crucial to consult a dietitian or healthcare provider for guidance on weight management and healthy eating habits.

It can lead to unhealthy behaviours and eating disorders

Adolescence is a critical phase of growth and development, and eating healthily is an integral part of a healthy lifestyle. Teenagers are susceptible to developing unhealthy behaviours and eating disorders, and restrictive diets like keto can be a contributing factor.

The keto diet is highly restrictive, eliminating or reducing essential food groups such as grains, fruits, and dairy. This restriction can lead to unhealthy behaviours as teenagers may feel deprived and crave these foods. It can also disrupt their cultural experience when eating with peers and family, as well as their relationship with food. A healthy relationship with food is crucial for teenagers to develop a positive body image and self-esteem. Restrictive diets can foster an unhealthy fixation on weight and appearance, which can be detrimental to their overall well-being.

Furthermore, the keto diet can affect a teenager's mental health. Calorie restriction and feelings of deprivation can result in low mood and increased anxiety. This can be especially challenging for teenagers who are already dealing with the emotional and physical changes of puberty.

The potential for developing unhealthy behaviours and eating disorders is a significant concern with the keto diet for teenagers. It is essential to encourage a positive relationship with food and promote a balanced approach to nutrition and weight management.

Keto can cause constipation and lethargy

The keto diet is a very high-fat, very low-carb, moderate-protein eating plan that induces a metabolic state called ketosis. In ketosis, the body burns fat instead of glucose for energy. While this can lead to weight loss, there can also be some negative side effects.

Constipation

The keto diet can cause constipation due to the drastic reduction in carbohydrate intake. Carbohydrates like fruits and whole grains are common sources of fiber, so transitioning to a low-carb diet can lead to digestive issues. The keto diet typically includes only 20 to 50 grams of carbs per day, which is far less than the recommended amount of 225 to 325 grams based on a 2,000-calorie diet. As a result, it can be challenging to get enough fiber, which is essential for maintaining healthy bowel movements.

Lethargy

The keto diet can also cause lethargy or fatigue due to several factors:

• The keto flu: Some people experience symptoms such as headaches, fatigue, and nausea as their body adjusts to lower carbohydrate intake.
• Cravings for carbohydrates: Restricting carbs can lead to initial feelings of tiredness and lethargy as cravings for whole grains and other carb-rich foods set in.
• Not enough calories: If dieters restrict their calorie intake too much, it can lead to a decrease in energy hormones, and their body may even enter "starvation mode."
• Not enough fat: If dieters do not consume enough fat, their body will be short on its primary source of energy, leading to exhaustion.
• Not eating regularly: Eating regularly is important for maintaining energy levels, especially when starting the keto diet.
• Lack of exercise: Incorporating regular exercise into your routine can help improve energy levels.
• Electrolyte imbalance: Ensuring adequate salt intake can help alleviate fatigue.

Preventing and Treating Constipation and Lethargy on Keto

To prevent and treat constipation and lethargy while on the keto diet, consider the following:

• Gradually introduce the keto diet: Start with a higher daily carb intake and slowly reduce it as your body adjusts.
• Increase fiber intake: Aim for 25 grams of fiber per day for women and 38 grams for men. Include keto-friendly, high-fiber foods like non-starchy vegetables, berries, avocados, and nuts.
• Drink enough water: Staying hydrated is essential for waste removal and can help prevent constipation.
• Cut back on dairy: Dairy products are allowed on the keto diet but can be hard to digest and lead to constipation.
• Add more salt: Increasing salt intake can help reduce negative side effects as the body adjusts to burning fat instead of glucose.
• Get regular exercise: Aim for a brisk daily walk or another form of aerobic exercise to encourage intestinal contractions and improve constipation.
• Retrain your bowel: Establish a regular time for bowel movements and drink enough fluids.

While the keto diet can be effective for weight loss, it is not recommended for children and teenagers due to the restricted carbohydrate intake, which can impact their mental and physical activity. Additionally, the keto diet can cause constipation and lethargy, especially during the initial adjustment period. It is important to work with a healthcare provider or dietitian to ensure the diet is safely implemented and monitored.
