Understanding Teen Nutritional Needs
Imagine a lunch comprising grilled chicken, brown rice, and steamed broccoli, followed by a dinner featuring salmon, sweet potato, and a green salad with only olive oil. What if each food item is limited to 4 ounces, and the total calorie intake for the day is restricted to about 1,500?
Does that sound adequate for a typical 15-year-old boy? Surprisingly, this was an AI-generated recommendation for him.
As many teens consider weight loss, it’s not uncommon for them to seek advice from AI platforms.
However, relying on AI for nutritional advice can be risky.
AI-generated meal plans may suggest calorie and nutrient levels that fall significantly below what is necessary for a teenager’s development, as highlighted in a recent study published in Frontiers in Nutrition.
According to Dr. Ayşe Betül Bilen, the lead author and assistant professor in nutrition and dietetics at Istanbul Atlas University, these AI meal plans provided to teens aimed at weight loss included an average deficit of 700 calories daily compared to guidance from human dietitians.
Additionally, there were notable discrepancies in the allocation of proteins, fats, and carbohydrates.
This issue is particularly alarming given the high rates of weight-loss attempts and AI usage among teenagers, noted Dr. Jason Nagata, an associate professor of pediatrics at the University of California, San Francisco, who was not involved in the research.
Nearly 48% of teens aged 16 and older claimed to have attempted weight loss in the past year, according to a January study. Additionally, a survey by the Pew Research Center found that almost two-thirds of teens use chatbots, with approximately 30% engaging with them daily. Thus, it is not surprising that adolescents rely on these tools for dietary guidance.
“While these technologies can offer general information, they should not replace professional advice, especially for children and adolescents whose nutritional requirements are distinct,” Bilen cautioned.
Despite the widespread use of generative AI among teens, both researchers and the general population lack thorough insights into the nature of the nutritional information teenagers receive from these platforms.
To evaluate the quality of nutritional advice from AI platforms, researchers developed four adolescent profiles: two boys and two girls, each identified as either overweight or obese based on body mass index (BMI).
Utilizing these profiles, the researchers queried five different AI models for a three-day meal plan, keeping in mind that the individuals were seeking to lose weight.
The resulting meal plans were then compared to the recommendations from dietitians. The AI-generated plans not only featured a larger calorie deficit but also had protein and fat levels that were considerably higher than those advised by dietitians, while carbohydrates were drastically lower.
“For adolescents, who are in a crucial stage of growth and development, these nutritional imbalances could be of significant concern if they are followed over the long term,” Bilen added.
Risks to Growth and Development
Misinformation regarding dietary guidelines poses significant risks for teenagers.
“Teenagers are in a phase of growth,” Nagata highlighted. “Inadequate nutrition can severely hinder their development, and in extreme cases, result in substantial health issues.”
Nagata has encountered dire situations where adolescents on continuous calorie deficits required hospitalization or intense medical care due to impaired heart or brain function caused by poor nutrition.
Another critical issue is that a diet excessively low in calories or with incorrect nutrient recommendations can foster eating disorders, as Nagata warned.
“While not all individuals seeking to lose weight will develop eating disorders, a considerable number may resort to unhealthy weight control practices such as fasting, meal skipping, purging, or taking unauthorized medications for weight loss,” he explained.
Generative AI may appear to present a feasible solution for adolescent nutrition or for anyone aiming to improve their diet.
Many individuals struggle with adhering to their nutritional goals and may lack access to qualified professionals, said Dr. Erin Hennessy, associate professor and Director of the ChildObesity180 initiative at Tufts University, who did not participate in the study.
However, this research illustrates that numerous chatbots are limited in their ability to furnish critical health information. Both youth and adults must improve their literacy regarding such technology, Nagata emphasized.
A significant challenge lies in the algorithms behind AI platforms that might be influenced by widespread nutritional misinformation available online, Dr. Natalie Muth, a pediatric obesity medicine expert, registered dietitian, and Namio Health cofounder, stated, having not been directly involved in the study.
There’s also a possibility that the AI evaluates unqualified advice as equally credible as evidence-based recommendations, Muth added.
“The AI does not critically assess these concerns,” Nagata pointed out. “It simply responds to your queries without offering the essential broader context that healthcare professionals or dietitians typically provide.”
These platforms are created to align with your requests, supplying information without challenging your assumptions or expanding on your questions. As opposed to healthcare providers who may counter unhealthy desires for rapid weight loss, algorithms are more likely to instruct you on how to achieve those goals.
This situation affects not just teens but also adults aiming to shed pounds.
While there might be advancements in the future that allow these platforms to better address discrepancies in nutritional advice, Nagata stressed the importance of families and teenagers recognizing these limitations and developing critical thinking skills regarding their prompts and the responses they receive.
For instance, had the hypothetical teens in the study requested weight-loss guidance aligned with nutritional and caloric requirements from the World Health Organization or another authoritative body, the information might have been more accurate.
“I encourage individuals to always verify AI-generated information through credible sources, like registered dietitians or other reputable entities,” Nagata advised.
Reflect on that meal plan for a 15-year-old boy that prescribed tiny portions totaling about 1,500 calories.
Even if he aims for weight loss, such a limited quantity falls short of nutritional needs. The requirements can vary, but on average, teenage boys need around 2,800 calories per day, while teenage girls typically require about 2,200, as noted by healthychildren.org, per the American Academy of Pediatrics.
Even on the lower end, the American Heart Association recommends that girls aged 14 to 18 receive approximately 1,800 calories daily, while boys should obtain around 2,200 calories.
Families should prioritize providing balanced meals for their teenagers rather than adhering to restrictive diets, Nagata emphasized.
“Teens often require more calories and nutrients than families realize due to growth spurts, puberty, and activity levels,” he noted in an email. “Teens should steer clear of crash diets, significant caloric restrictions, and non-prescribed weight loss solutions.”
If there are concerns regarding a teen’s nutritional status or growth, it is advisable for families to consult with a pediatrician or registered dietitian for expert medical guidance.
