ISSA Nutritionist Practice Exam: Practice Test & Study Guide

The term that describes any irregular eating behavior, such as binge eating or purging, is disordered eating. This concept encompasses a wide spectrum of behaviors that deviate from healthy eating patterns, including both overeating and undereating. Disordered eating may involve emotional factors and can lead to serious health issues if not addressed.

Orthorexia refers to an unhealthy obsession with eating only healthy foods, which is a specific type of disordered eating but does not cover the range of behaviors like binge eating or purging. Anorexia is a specific eating disorder characterized by extreme restriction of food intake and an intense fear of gaining weight, which represents a narrow subset of disordered eating behaviors. Mindful eating is a practice that encourages individuals to become more aware of their eating habits and choices, promoting a healthier relationship with food, rather than describing irregular eating behaviors.
