Resumen

SILVA, Jaime R. Anxiety Induced Overeating: Part I: Behavioral, Affective, Metabolic and Endocrine Evidence. Ter Psicol [online]. 2007, vol.25, n.2, pp.141-154. ISSN 0718-4808.  http://dx.doi.org/10.4067/S0718-48082007000200005.

Under stress, chronic alimentary restraint behaviors usually alternate with overeating. Restrained eaters (RE) are especially prone to show these paradoxical patterns. This paper reviews behavioral, affective, endocrine and metabolic evidence related to that condition. Laboratory and field studies have shown that RE overeat mainly under anxiety-related experimental setting. This observation has been explained by several psychological theories, such as the psychosomatic theory, the cognitive distraction theory and the masking hypothesis. However, empirical data does not support all these views in an equivalent way. At the same time, endocrine and metabolic research suggest that RE may have predisposition to weight gain due to chronic stress exposure, which in turn lead to increased risk of obesity. The review concludes with controversies in the literature and recommended directions for future research in the field

Palabras clave : Restrained eaters; eating disorders; obesity; emotional eaters.
