“…In contrast, LOC status did not impact the PSE curve for low‐ED foods. Our results are supported by past work showing that children with LOC compared with those without have different energy intake patterns and may have selective bias towards high‐ED foods . Eating‐related LOC is linked to disinhibited eating patterns such as emotional eating and negative affective states , indicating that those who report LOC may turn to higher ED foods as a coping strategy to improve mood.…”

“…This favoring of habit learning may underlie the compulsive habit responding that is characteristic of these disorders and represent a dysfunction in a neurocomputational mechanism of learning. In addition, individuals with BED, food addiction, and obesity all show heightened sensitivity and attentional biases to food cues at a behavioral level ( (Lawrence et al, 2012), BMI (Shank et al, 2015), and severity of self-reported symptoms (Schmitz et al, 2014). In animal models of addiction, habitual responding is measured through the persistence of responding following a devaluation of the reward outcome, such as the addition of bitter-tasting quinine, lithium-chloride-induced postingestive malaise, or specific satiety, where free access to the reward is given prior to the test.…”

Compulsive eating behavior is a transdiagnostic construct that is characteristic of medical and psychiatric conditions such as forms of obesity and eating disorders. Although feeding research is moving toward a better understanding of the proposed addictive properties of food, the components and the mechanisms contributing to compulsive eating are not yet clearly defined or understood. Current understanding highlights three elements of compulsive behavior as it applies to pathological overeating: (1) habitual overeating; (2) overeating to relieve a negative emotional state; and (3) overeating despite aversive consequences. These elements emerge through mechanisms involving pathological habit formation through an aberrant learning process, the emergence of a negative emotional state, and dysfunctions in behavioral control. Dysfunctions in systems within neurocircuitries that comprise the basal ganglia, the extended amygdala, and the prefrontal cortex result in compulsive eating behaviors. Here, we present evidence to relate compulsive eating behavior and addiction and to characterize their underlying neurobiological mechanisms. A major need to improve understanding of compulsive eating through the integration of complex motivational, emotional, and cognitive constructs is warranted.

“…The study found a 2-way interaction between BMI-z score and LOC eating such that among those with LOC (but not those without LOC), attentional bias toward high palatable foods (vs. neutral) was positively associated with BMI-z. 57 On balance, the studies described suggest hyperactivation of reward regions and hypoactivation of cognitive control regions among obese children, with contradictory findings (eg, Davids et al 56 ) potentially explicable by differences in pre-scan intake or sample characteristics (eg, conscious dietary restraint).…”

Overlapping neurobehavioral circuits in ADHD, obesity, and binge eating: evidence from neuroimaging research

et al. 2015

Attention-deficit/hyperactivity disorder (ADHD) and conditions involving excessive eating (e.g. obesity, binge / loss of control eating) are increasingly prevalent within pediatric populations, and correlational and some longitudinal studies have suggested inter-relationships between these disorders. In addition, a number of common neural correlates are emerging across conditions, e.g. functional abnormalities within circuits subserving reward processing and executive functioning. To explore this potential cross-condition overlap in neurobehavioral underpinnings, we selectively review relevant functional neuroimaging literature, specifically focusing on studies probing i) reward processing, ii) response inhibition, and iii) emotional processing and regulation, and outline three specific shared neurobehavioral circuits. Based on our review, we also identify gaps within the literature that would benefit from further research.
