Entering university often marks the beginning of new independence, accompanied by changes in eating habits that can be surprising. The famous "freshman 15" is not just a student legend, but has its roots in precise behavioral mechanisms that science is beginning to clarify.
A research team from George Mason University conducted an in-depth study on student eating behaviors. For four weeks, participants recorded their daily habits via a specially designed mobile application. This innovative method allowed for the capture of accurate data about meal environments, emotions, and quantities consumed, providing a detailed overview of factors influencing eating in the university setting.

The results show that the social environment plays a determining role in the amount of food consumed. Meals taken in groups of two or more people, particularly in university dining halls or restaurants, systematically lead to higher calorie consumption. Conversely, solitary meal times at home correspond to reduced food intake, revealing the significant impact of others' presence on our nutritional behaviors.
A surprising aspect of the study concerns students' perception of their own eating. Researchers found a significant gap between the actual amount of calories consumed and participants' personal estimates. This lack of awareness about one's own eating habits proves particularly pronounced in social situations, where attention to what one is eating decreases in favor of interactions with others.

mHealth highlights the diversity of eating behaviors, where individual, interpersonal, and environmental factors intertwine. Emotions, stress, and even participants' gender appear as variables influencing nutritional choices. These discoveries open interesting perspectives for developing dietary interventions better adapted to the realities of student life.
