From a developmental standpoint, the brain circuits that respond to reward and habit are still maturing during the late teens. That makes this period a sensitive window: external cues and highly palatable foods can more strongly steer behavior than they might in older adults. If adolescents are more likely to eat when not hungry after exposure to certain diets, those eating episodes can accumulate into weight gain and altered relationships with food over time.

Understanding these dynamics opens paths for better policies, school programs, and family strategies that support healthier choices and more equitable outcomes. The study raises practical questions about how food environments influence growing minds and bodies, and whether small changes in what’s available could shift trajectories of health and opportunity.

A Virginia Tech study shows that ultra-processed foods may influence adolescents differently from slightly older young adults. Participants aged 18 to 21 ate more at a buffet and snacked even when not hungry after two weeks on an ultra-processed diet. Because eating without hunger predicts future weight gain, these findings hint at a heightened vulnerability during late adolescence.
