“…Breakfast was provided in order to standardize the timing between meals. The breakfast calorie content (300 Calories) reflected a standard meal likely to be recommended during regular daily intake, and one that prior research has shown is consumable and less likely to induce severe anxiety in eating disorder participants in a research setting ( 38 , 39 ). The lunch calorie content (1,000 Calories) reflected an amount expected to be associated with aversive anticipation in individuals with AN, but not so high that it would be unreflective of a typical lunch meal consumed by an unaffected individual.…”

Interoceptive Anxiety and Body Representation in Anorexia Nervosa

et al. 2018

Individuals with anorexia nervosa (AN) typically display anxious traits prior to the onset of food avoidance and weight loss that characterize the disorder. Meal associated anxiety is an especially common clinical feature in these patients, and heightened sensitivity to sympathetically mediated interoceptive sensations has also been observed. However, it remains unclear how heightened interoceptive sensitivity relates to experiences of anxiety before and after meals. To investigate this relationship, we experimentally induced anxiety and panic symptoms with isoproterenol, a peripheral sympathetic agonist similar to adrenaline, across several different conditions: during panic provocation, during anticipation of a 1,000 Calorie meal, and after meal consumption. Fifteen AN and 15 age- and sex-matched healthy comparisons received bolus infusions of isoproterenol and saline in a double-blinded, randomized design. Participants rated anxiety symptoms after each infusion, completed panic rating scales, and traced the location of perceived palpitations on a manikin to index interoceptive “body map” representation. The AN group reported significantly elevated anxiety relative to healthy comparisons during infusions before and after the meal, but surprisingly, not during panic provocation. These symptoms were accompanied by geographical differences in patterns of perceived heartbeat sensations across each condition. In particular, the AN group localized heartbeat sensations disproportionately to the chest during meal related saline infusions, when no cardiorespiratory modulation actually occurred. The AN group also showed a trend toward higher panic attack rates during the meal anticipation period. Correcting for anxiety levels reported during saline infusions abolished group differences in anxiety change across all conditions, suggesting a significant contribution of anxious traits in AN. The observation of meal related “visceral illusions” provides further evidence that AN is associated with abnormal interoceptive representation of the heartbeat and suggests that meal consumption, particularly when anticipated, preferentially alters the processing of interoception related signals in AN.

“…Research using implicit and explicit measures has shown that typically rewarding experiences, such as viewing or consuming palatable foods [20,21,28,29] watching humorous videos [30,31], or perceiving prosocial emotions or touch [22,32,33] are less subjectively pleasant, and in some cases more aversive, for individuals with AN compared to HCs. Reward experiencing has been shown to engage similar brain structures as reward anticipation, most notably the ventral tegmental area and striatum interacting with the orbitofrontal cortex [15,17].…”

Accumulating psychobiological data implicate reward disturbances in the persistence of anorexia nervosa (AN). Evidence suggests that individuals with AN demonstrate decision-making deficits similar to those with mood and anxiety disorders that cause them to under-respond to many conventionally rewarding experiences (e.g., eating, interacting socially). In contrast, unlike individuals with other psychiatric disorders, individuals with AN simultaneously over-respond to rewards associated with eating-disorder behaviors (e.g., restrictive eating, exercising). This pattern of reward processing likely perpetuates eating-disorder symptoms, as the rewards derived from eating-disorder behaviors provide temporary relief from the anhedonia associated with limited responsivity to other rewards. Positive Affect Treatment (PAT) is a cognitive-behavioral intervention designed to target reward deficits that contribute to anhedonia in mood and anxiety disorders, including problems with reward anticipation, experiencing, and learning. PAT has been found to promote reward responsivity and clinical improvement in mood and anxiety disorders. This manuscript will: (1) present empirical evidence supporting the promise of PAT as an intervention for AN; (2) highlight nuances in the maintaining processes of AN that necessitate adaptations of PAT for this population; and (3) suggest future directions in research on PAT and other reward-based treatments that aim to enhance clinical outcomes for AN.

“…Prior characteristics of emotions spreaded in economic behaviour: gender differences of emotions experienced and social nature of that differences (Anderson et al, 2014;Cavanaugh et al, 2015;Godefroit-Winkel et al, 2019). But beyond that, certain phenomena are known as a result of consumption and emotion intersection and at the moment don't have a transfer to other areas.…”
