“…During the food‐cue task, a significant elevation of frontal beta power was found in women with obesity compared to an age‐matched normal weight control group (Hume, Howells, Rauch, et al, ). However, no differences in the EEG power spectrum were identified between women with obesity who had lost but subsequently regained at least 10% of their body weight versus women with sustained obesity (Hume, Howells, Karpul, et al, ).…”

“…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 .…”

“…Two of three studies investigating obesity included otherwise healthy adults with obesity (BMI ≥ 30.0 kg/m 2 ;Hume, Howells, Karpul, et al, ; Hume, Howells, Rauch, et al, ), and one study investigated adolescent girls with a BMI percentile ≥ 85 (Bauer & Manning, ; Hume, Howells, Karpul, et al, ; Hume, Howells, Rauch, et al, ). The EEG was derived from 10 (Hume, Howells, Karpul, et al, ; Hume, Howells, Rauch, et al, ) and 64 electrode positions (Bauer & Manning, ) according to the international 10–20 system and was recorded during a modified Stroop task using office and food stimuli (Hume, Howells, Karpul, et al, ; Hume, Howells, Rauch, et al, ) and during a working memory and sustained attention task (Bauer & Manning, ). The modified Stroop task used by Hume, Howells, Karpul, et al () and Hume, Howells, Rauch, et al () was divided into three distinct subtests: a practice task, a control task, and a food‐cue task (Hume, Howells, Karpul, et al, ; Hume, Howells, Rauch, et al, ).…”

“…One major limitation to the study quality in studies examining BED was the diagnostic method, consisting of self‐administered questionnaires instead of a clinical interview. In addition, four studies (Hume, Howells, Karpul, et al, ; Hume, Howells, Rauch, et al, ; Imperatori et al, ; Wolz et al, ) addressed a possible alpha error accumulation.…”

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.
