Functional foods and fitness for the management of pediatric obesity are growing areas of interest in medicine. Pediatric obesity rates are on the rise in resource-rich countries, especially the United States. Statistics show that 19.7% of children in the United States are overweight or obese. These prevalence rates raise significant concerns for the health of overweight children across their lifespan. Obesity in childhood can cause immediate and long-term health consequences such as diabetes, hypertension, heart disease, and liver dysfunction. Functional foods and targeted fitness programs show promise as effective treatments for this condition.

Understanding Pediatric Obesity 

An overview of pediatric obesity can provide insight into the causes, health risks, and management challenges. Pediatric obesity is more prevalent among Native American, Black, and Hispanic children. Additionally, children in low-income situations are more likely to be overweight or obese. These statistics raise concerns about health access disparities among these populations. Additionally, a child is more likely to become obese if one or both parents are obese. These obesity prevalence rates and disparities among certain populations have become a catalyst for further research into effective interventions for preventing and treating childhood obesity.

The Role of Functional Foods in Pediatric Obesity 

Dietary choices for pediatric obesity are a very important component of condition management. Functional foods have high levels of nutrients and work to promote systemic health. These foods have a high nutrient density, meaning they are rich in micronutrients and fiber but lower in calories. Nutrient-dense foods allow for the ingestion of appropriate amounts of fiber to promote satiety. Children with obesity should be encouraged to increase their intake of functional foods, including fruits, vegetables, whole grains, and lean protein. Water should be chosen more often than sweetened beverages (e.g. juice, soda). Childhood obesity is accelerated by a high intake of processed and high-calorie foods. These foods are dense in fat and sugar but lacking in micronutrients. Many families choose these foods due to convenience, cost, and lack of access to healthy foods. 

Five servings of fruits and vegetables per day is the recommended intake. These foods should be offered to the child at every meal. Providers should encourage the parents that integrating new foods into the child’s routine may take time. The entire family should incorporate dietary changes together and the child should not be made to feel that they are being singled out or “put on a diet”. 

Designing Targeted Fitness Programs for Obese Children 

Targeted fitness interventions include physical activity programs that are specially designed to engage children and adolescents. A sedentary lifestyle is a significant contributor to the development of obesity in children and adults. Children with obesity need specific physical activity guidelines that are tailored to their individual needs. These interventions should be realistic and engaging for the child. Aerobic exercise is an effective exercise program for obesity treatment. Common examples include running, jumping rope, cycling, walking, sports, and water activities. The chosen exercise must be something the patient enjoys, which promotes adherence. Exercise that incorporates the child’s social network (e.g. dance class, sports teams) can also promote enjoyment and consistency. Similar to dietary interventions, the caregiver and whole family should increase their physical activity as a unit. 

Preschool patients should be encouraged to engage in active play, which enhances their physical health and overall development. School-age and adolescent children should engage in one hour of physical activity per day. This includes aerobic activity and resistance exercise to promote muscle development. Resistance training intensity is dependent on the child’s age and stage of development. The patient’s pediatrician should be consulted before resistance training exercise is started.

Integrating Nutrition and Exercise in Treatment Plans 

‍Combining nutrition and exercise into the obesity treatment plan is a vital component of holistic care. Functional foods increase energy, which helps the patient adhere to new physical activity goals. Better nutrition can help the patient’s stamina in aerobic exercise as well as resistance training. Increasing the intake of healthy foods and improved physical fitness both promote better sleep, an important part of healthy weight and overall well-being. Providers should provide education and create goals for nutrition and fitness, emphasizing the symbiotic relationship of both interventions.

Challenges in Implementing Functional Food and Fitness Strategies 

Challenges in obesity management are significant and require provider education as well as open communication to promote healthy outcomes. One challenge is parent/caregiver modeling behavior. The adult at home should be encouraged to model healthy lifestyle changes. As previously mentioned, it is important that the entire household attempts to integrate healthy changes as a unit. The foods purchased and brought home make a significant impact on the dietary patterns of the whole family. Meal planning and grocery shopping should be encouraged, with an emphasis on choosing functional foods. If less processed and nutrient-poor foods are brought into the home, there will be fewer opportunities for the child to eat them. Meals cooked and eaten at home appear to be associated with better weight loss and overall health outcomes. The family should be encouraged to eat less fast food and eat at the table together. Meals consumed in front of the TV are associated with increased calorie intake and less attention to satiety. 

The dietary preferences of children can be a difficult barrier to integrating functional foods into the diet of the child and family. Vegetables in particular can be difficult to add to the daily meal routine of the pediatric patient. It is recommended that at least one food be served that the child enjoys, along with new foods. Children are more likely to eat foods they were involved in planning or preparing. 

The treating provider needs to recognize the potential disparities in income, access to healthy foods, and transportation challenges that can contribute to obesity. Addressing these barriers requires knowledge of assistance available and careful communication to avoid shame or embarrassment. Many states offer nutrition assistance programs with vouchers for farmer's markets and stores with healthy options. The treating healthcare provider can provide education about these programs to help the child and family integrate healthy lifestyle changes.

Monitoring obesity interventions is an important part of the treatment course. A clear plan should be made initially by the patient, family, and treating provider. This plan should include clear steps and follow-up. Routinely monitoring body mass index (BMI) compared to the BMI for age growth chart can help chart progress and efficacy in interventions. Waist circumference and body mass index should also be closely monitored. During follow-up visits, the provider can inquire how dietary and physical activity changes are going, and provide education if necessary. Encouragement from the care team to integrate interventions is an important part of adherence. 

A behavioral model appears to be the most effective in encouraging long-term change. This model involves recording a log of physical activity and food intake, to gather data and promote awareness. Secondly, identifying stimuli in the physical environment and routines that contribute to obesity can help change behaviors. These obesity-promoting habits include mindless snacking, eating in front of screens, and emotional eating. Tracking sleep is also an important component of obesity prevention and overall health promotion. Goal-setting is the third component of this behavior model of change. These goals should be realistic and achievable. Follow-up with the healthcare provider can help assess adherence. Community-based interventions are also effective in promoting health in childhood and adolescence.

The Let’s Move campaign was implemented in partnership with the US government to address pediatric obesity. This program used individualized coaching as well as text message communication for follow-up and monitoring. These avenues of follow-up with the patients and families proved effective for integrating healthy lifestyle behaviors. During follow-up and assessments, goals should be changed as needed depending on the child’s progress and individual needs.

The Role of Healthcare Professionals and Caregivers 

Healthcare guidance in pediatric obesity is a multidisciplinary approach involving dieticians, pediatricians, and mental health professionals. In most scenarios, the pediatrician will be the primary professional in screening for, identifying, preventing, and managing obesity in young patients. Dieticians play an important role in the care team for pediatric obesity. These professionals can work with the patient and caregivers to create a healthy eating plan that is balanced in micro and macronutrients. It is preferred that the dietician has experience in the field of pediatric weight management. In some cases, mental health professionals may be consulted to help the child cope with the mental strain that can accompany weight challenges. 

These clinicians can assess for depression, anxiety, low self-esteem, and bullying. Children with high body mass index for their developmental stage may experience mental health challenges. Mental health professionals are a vital part of the treatment unit because they can identify and help address the non-physical effects of obesity. Comprehensive weight management programs are an effective choice for treatment where available. These teams consist of nutrition professionals and behavior modification specialists who assist with integrating healthy lifestyle changes. In some cases, pharmacotherapy and surgical intervention for weight loss may be applicable. These steps are typically reserved for adolescents and patients with intractable obesity. 

The family and caregivers play a vital role in the success of weight loss interventions and in building lifelong healthy habits. As previously mentioned, nutrition and physical activity changes must involve the whole family, not just the child who is overweight. Behavioral change should engage the children and caregivers, especially in habit changes such as eating more meals at home at the table. Data shows that engaging the family unit in weight loss treatment is more effective in the long term. At least one parent or caregiver should be involved in visits with dieticians and behavior management specialists. The pediatrician can help encourage family involvement and assess for knowledge gaps that may affect treatment.
