Diet and Behavior

Diet and Behavior (Adult Population)

The CNP Diet and Behavior Research Category focuses on a wide range of observable, measurable eating-related actions, including what, when, and how much people eat. It includes dietary habits such as food preparation, purchasing, and consumption patterns; emotional and social influences on food choices; habitual snacking; and eating restriction. These patterns are shaped by psychological factors—including mood, cognition, stress, and emotions—which together exert a reciprocal influence on eating behaviors and play a significant role in shaping overall well-being and mental health outcomes.

  • Reviewed By CNP STAFF

Rodent eating behavior is regulated by post-ingestive nutritional signals to the brain, and disordered eating behavior and obesity have been linked to inadequate responses to these signals. In this study by van Galen et al. (2023), the authors conducted a single-blinded, randomized, controlled, crossover research in 30 healthy people (females N = 12, men N […]
