AI diet plans for teens fall dangerously short on nutrition, study warns
Artificial intelligence tools are giving teens questionable meal advice, a new study has found. Researchers discovered that AI-generated diet plans often fall short of nutritional needs, sometimes cutting calories by as much as 700 a day. This could harm growth and health during a crucial stage of development.
The study, published in Frontiers in Nutrition, tested five AI models by creating meal plans for four fictional 15-year-olds. Each plan aimed at weight loss over three days. The results showed big gaps in protein, fats, and carbohydrates when compared to dietitians' recommendations.
On average, the AI plans provided 700 fewer calories than experts advised. Official guidelines suggest teen boys need around 2,200 to 2,800 calories daily, while girls require 1,800 to 2,200. The study warned that long-term imbalances could stunt growth or worsen eating disorders. Unlike human dietitians, AI often agrees with users' requests without questioning assumptions. It may pull from unreliable online sources, treating unqualified advice as equal to expert guidance. Families are now being urged to check AI meal plans against trusted sources, like registered dietitians or health organisations. Experts stress the importance of balanced meals over restrictive diets. Poor nutrition during adolescence can have lasting effects on both physical and mental health.
The findings highlight the risks of relying on AI for diet advice without oversight. Teens and parents should approach automated meal plans with caution. Verifying information with professionals remains the safest way to ensure proper nutrition during key growth years.
