A complex interplay of peripheral and central signaling mechanisms within the body of an organism
maintains energy homeostasis. In addition, energy/food intake is modified by various external factors (e.g., palatability,
food availability, social and environmental triggers). Highly palatable foods can provoke maladaptive
feeding behavior, which in turn disrupts normal homeostatic regulation resulting in numerous health consequences.
Furthermore, neuroendocrine peptides, traditionally considered to regulate appetite and energy homeostasis,
also control the intake and reinforcing properties of alcohol and drugs of abuse. Therefore, dysregulated
eating as a result of a hedonic/binge-like intake of hyper-palatable food may impact alcohol drinking behavior.
Relevant in this case is the fact that eating disorders are highly comorbid with several neuropsychiatric conditions,
including alcohol use disorder. The present review is intended to summarize the neurobiological and functional
consequences of hedonic feeding on alcohol intake.
Keywords: High-fat diet, alcohol, nutritional contingency, palatable diet, alcohol use disorder, homeostatic, neuroendocrine.
