“…In terms then of the nature of a general model of hunger, it seems reasonable to presume a basis in learning and memory. This is partly because of the longevity and success of learning and memory-based “appetite” models in animals and humans, but more generally because of the serious effect on the experience of human hunger wrought by MTL damage (Parent et al, 2022; Seitz, Tomiyama, et al, 2021). Consequently, the first problem we address is what would a general—all food types—learning and memory-based model of hunger look like, and how would this integrate physiological information?…”

“…There is a substantial body of research demonstrating a relationship between episodic memory and eating behavior (Higgs & Spetter, 2018; Seitz et al, 2021). Perhaps the most striking evidence comes from patients with the inability to form episodic memories (due to hippocampal damage), who, without memory for having recently eaten, will continue to eat multiple meals within a short period of time (Rozin et al, 1998).…”

ObjectiveHuman behaviors, thoughts, and emotions are guided by memories of the past. Thus, there can be little doubt that memory plays a fundamental role in the behaviors (e.g., binging), thoughts (e.g., body‐image concerns), and emotions (e.g., guilt) that characterize eating disorders (EDs). Although a growing body of research has begun to investigate the role of memory in EDs, this literature is limited in numerous ways and has yet to be integrated into an overarching framework.MethodsIn the present article, we provide an operational framework for characterizing different domains of memory, briefly review existing ED memory research within this framework, and highlight crucial gaps in the literature.ResultsWe distinguish between three domains of memory—episodic, procedural, and working—which differ based on functional attributes and underlying neural systems. Most recent ED memory research has focused on procedural memory broadly defined (e.g., reinforcement learning), and findings within all three memory domains are highly mixed. Further, few studies have attempted to assess these different domains simultaneously, though most behavior is achieved through coordination and competition between memory systems. We, therefore, offer recommendations for how to move ED research forward within each domain of memory and how to study the interactions between memory systems, using illustrative examples from other areas of basic and clinical research.DiscussionA stronger and more integrated understanding of the mechanisms that connect memory of past experiences to present ED behavior may yield more comprehensive theoretical models of EDs that guide novel treatment approaches.Public SignificanceMemories of previous eating‐related experiences may contribute to the onset and maintenance of eating disorders (EDs). However, research on the role of memory in EDs is limited, and distinct domains of ED memory research are rarely connected. We, therefore, offer a framework for organizing, progressing, and integrating ED memory research, to provide a better foundation for improving ED treatment and intervention going forward.

“…Further, better episodic recall is associated with less uncontrolled and emotional eating, and more strategic dieting, as well as a higher likelihood of avoiding fatty food consumption (129). Interestingly, hippocampal volume (a brain area important in memory functioning) has been repeatedly associated with diet-related outcomes, such as being overweight or obese (123). Different cognitive functions play an important role in eating behavior, therefore changes in these cognitive functions during pregnancy will impact eating behavior.…”

Dietary choice during pregnancy is crucial not only for fetal development, but also for long-term health outcomes of both mother and child. During pregnancy, dramatic changes in endocrine, cognitive, and reward systems have been shown to take place. Interestingly, in different contexts, many of these mechanisms play a key role in guiding food intake. Here, we review how food intake may be impacted as a function of pregnancy-induced changes across species. We first summarize changes in endocrine and metabolic signaling in the course of pregnancy. Then, we show how these may be related to cognitive function and reward processing in humans. Finally, we link these to potential drivers of change in eating behavior throughout the course of pregnancy.
