Obesity has proven difficult to treat. Many approaches neglect to address the deep-rooted underlying psychological issues. This paper describes a psychodynamically oriented approach to treating compulsive overeating as an addiction. Common to all addictions is a compulsion to consume a substance or engage in a behavior, a preoccupation with using behavior and rituals, and a lifestyle marked by an inability to manage the behavior and its harmful consequences. The approach represents a shift away from primarily medical models of intervention to integrated models focusing on the psychological underpinnings of obesity...

The mesolimbic dopamine (DA) system is known to play a role in cue-mediated reward-seeking for natural rewards and drugs of abuse. Specifically, cholinergic and glutamatergic receptors in the ventral tegmental area (VTA) have been shown to regulate cue-induced drug-seeking. However, the potential role of these VTA receptors in regulating cue-induced reward seeking for natural rewards is unknown. Here, we examined whether blockade of VTA acetylcholine receptors (AChRs) and N-methyl-d-aspartate receptors (NMDARs) would alter cue-induced sucrose seeking in male Sprague-Dawley rats...

We used prenatally restraint stressed (PRS) rats, which show abnormalities in the reward system and anxious/depressive-like behavior. Some of the hallmarks of PRS rats are known to be sex-dependent. We report that PRS enhanced and reduced milk chocolate-induced conditioned place preference in males and females, respectively...
