Behavioral nutrition is an approach that focuses on the relationship between human behavior and food. This includes how people choose what to eat, when to eat, how much to eat and why. Behavioral nutrition also focuses on how environment, culture, emotions, and other psychological factors affect food choices. The goal of behavioral nutrition is to help people develop healthy eating habits and achieve and maintain a healthy weight. This can be achieved through behavior change techniques such as self-monitoring , goal setting and self-reflection.
