Appetiterelated

Appetiterelated is an adjective used to describe phenomena, measurements, or processes connected with appetite and the regulation of energy intake. While the term is not a formal classification in all disciplines, it is used to discuss factors that influence hunger, fullness, food choice, and consumption.

The scope includes physiological signals such as ghrelin, leptin, and insulin that help regulate hunger and satiety; hedonic and cognitive factors that affect food reward; and environmental cues like food availability, portion sizes, and social context. It also encompasses psychological states such as stress, mood, and habit, as well as circadian and metabolic influences on appetite.

In research and clinical settings, appetite-related measures may involve self-report questionnaires, behavioral tests of intake, metabolic assessments, and neuroimaging to study brain regions involved in food reward and hunger signaling. The term helps frame interdisciplinary studies that integrate biology, psychology, nutrition, and public health.

Applications include understanding obesity and eating disorders, improving weight-management interventions, and investigating conditions such as anorexia nervosa, bulimia nervosa, and cancer cachexia where appetite regulation is disrupted.
