“…Out of the seven included studies investigating eight samples, two studies analyzed spectral power in individuals with BN (Léonard, Pepinà, Bond, & Treasure, ; Wolz et al, ), three studies investigated individuals with BED (Imperatori et al, ; Tammela et al, ; Wolz et al, ), and three studies investigated individuals with obesity only (Bauer & Manning, ; Hume, Howells, Karpul, et al, ; Hume, Howells, Rauch, Kroff, & Lambert, ). All characteristics of included studies are summarized in Table .…”

“…Léonard et al () and Wolz et al () examined EEG brain activity in women with BN (American Psychiatric Association, , ). BN was determined via clinical expert rating (Léonard et al, ) and a semistructured expert interview (Wolz et al, ). Léonard et al () derived the EEG at two standard positions according to the international 10–20 system (Cz and C3) at 1‐min resting‐state eyes open before, during, and after a test meal.…”

The test meal consisted of a mid‐morning snack of about 1,350 kJ (Léonard et al, ). Wolz et al () derived the EEG from 60 electrode positions (10–20 system) and used four active electrodes (Fz, FCz, F1, F2) to determine changes in frontal theta activity during a 1‐min odor presentation with a neutral (pencil smell) and a chocolate (piece of chocolate) aroma, followed by a visual presentation of 56 neutral (office items) or chocolate pictures.…”

To provide a basis for electroencephalography (EEG) neurofeedback protocols for bulimia nervosa (BN), binge‐eating disorder (BED), and obesity, this systematic review investigates alterations in EEG‐measured brain activity, specifically frequency bands. A systematic literature search with predefined search terms yielded N = 7 studies meeting the inclusion criteria. The risk of bias was assessed for all studies. In resting‐state EEG, the beta activity was elevated in fronto‐central regions in individuals with obesity and co‐morbid BED. In food‐cue conditions, both obese individuals with and without BED showed increased beta activity, suggesting increased awareness of food cues and a heightened attentional focus towards food stimuli. The level of beta activity was positively correlated with eating disorder psychopathology in resting and food‐cue conditions. In individuals with BN, there was no evidence for altered EEG spectral power. The results indicate specific alterations in EEG‐based brain activity in individuals with BED and obesity. More high‐quality studies are needed to further confirm these findings and to transfer them into EEG‐based interventions.

Objective Sensor technologies offer exciting potential to objectively measure psychopathological correlates of eating pathology and eating disorder (ED) research utilizing sensors has rapidly proliferated in the past several years. The aims of the present review are: (1) characterize the types of sensors that have been utilized in ED research, (2) identify the psychopathological factors relevant to EDs that have been assessed using sensors, (3) describe the data supporting the validity and reliability of these sensors, (4) discuss limitations associated with these sensors, and (5) identify gaps that persist within the ED literature with regard to use of sensor technologies. Method A systematic search was conducted of PubMed, PsycINFO, Web of Science, ProQuest, and “gray” literature sources. Eligible publications were empirical studies that utilized sensors to measure at least one psychological variable among clinical ED populations. Results Sensors have been utilized with ED samples to measure eating behaviors, physical activity, sleep, autonomic nervous system activity, eyeblink startle response, visual attention, and visual‐haptic object integration. The reliability and validity of these sensors varies widely and there are a number of significant gaps that remain in the literature with regard to the types of sensors utilized, context in which sensors have been used, and populations studied. Discussion The existing literature utilizing sensors within ED research largely support the feasibility and acceptability of these tools. Sensors should continue to be utilized within the field, with a specific focus on examining the reliability and validity of these tools within ED samples and increasing the diversity of samples studied. Public Significance Statement Sensor technologies, such as those included in modern smartwatches, offer new opportunities to measure factors that may maintain or contribute to symptoms of eating disorders. This article describes the types of sensors that have been used in eating disorders research, challenges that may arise in using these sensors, and discusses new applications of these sensors that may be pursued in future research.
