Risks of AI-Generated Meal Plans for Teenagers

Overview of the Study's Findings
A recent study conducted by researchers at Istanbul Atlas University has raised concerns about the use of artificial intelligence (AI) chatbots, such as ChatGPT and Gemini, for generating meal plans aimed at teenagers seeking to lose weight. The study, published on March 11, 2026, in *Frontiers in Nutrition*, found that these AI-generated plans often provide inadequate caloric and nutrient intake, which could lead to malnutrition and eating disorders among adolescents.
Researchers tested five AI models—ChatGPT 4, Gemini 2.5 Pro, Bing Chat-5GPT, Claude 4.1, and Perplexity—by asking them to create three-day meal plans for four hypothetical 15-year-olds with varying weight statuses. The AI-generated plans averaged nearly 700 calories less than those created by a registered dietitian, a significant difference that could adversely affect a teen's health.
Nutritional Deficiencies in AI Meal Plans
The study highlighted that the AI models not only underestimated the total energy requirements for teenagers but also miscalculated the necessary macronutrient distribution. AI plans suggested that 21% to 24% of energy intake should come from protein, 41% to 45% from fats, and only 32% to 36% from carbohydrates. In contrast, U.S. dietary guidelines recommend that 15% to 20% of calories come from protein, 30% to 35% from fats, and 45% to 50% from carbohydrates. This imbalance poses risks during a critical growth period for adolescents, as noted by lead researcher Dr. Ayse Betül Bilen.
Implications for Adolescent Health
Dr. Bilen emphasized the potential dangers of following AI-generated meal plans, stating, “Following such unbalanced or overly restrictive meal plans during the teenage years may negatively affect growth, metabolic health, and eating behaviors.” The reliance on AI tools that do not reference established nutritional guidelines raises alarms about their suitability for dietary planning.
Criticism of AI Tools
Experts have criticized the current state of AI in dietary advice. Anastasia Kalea, a senior nutrition researcher at University College London, pointed out that AI models often depend on generalized data rather than personalized dietary needs. This lack of individualization can make AI-generated plans less effective and potentially harmful compared to those crafted by trained dietitians, who consider a person's unique medical history and dietary requirements.
Official Statements & Responses
The researchers have called for caution among teenagers using AI for diet planning. They advocate for the development of safer AI tools that incorporate professional guidance to ensure nutritional adequacy. Dr. Bilen remarked, “AI models are primarily trained to generate responses that appear plausible and user-friendly rather than clinically precise.”

- “Anastasia Kalea, a senior nutrition researcher from University College London, said: “While digital platforms provide a stigma-free sanctuary for people living with obesity, the current reliance on AI tools presents a significant risk: many of these models depend on generalised, publicly available data rather than the nuanced diet and medical history information of the individual which would be collected meticulously by a healthcare professional trained in dietetics and nutrition.” — Anastasia Kalea, Senior Nutrition Researcher, University College London.
The findings of this study underscore the importance of professional oversight in dietary planning for adolescents, particularly in an era where AI tools are increasingly accessible.
