Night Eating Syndrome

Night eating syndrome (NES) is an eating disorder, characterized by a delayed circadian pattern of food intake.[1] Although there is some degree of comorbidity with binge eating disorder,[1] it differs from binge eating in that the amount of food consumed in the night is not necessarily objectively large nor is a loss of control over food intake required. It was originally described by Albert Stunkard in 1955[2] and is currently included in the other specified feeding or eating disorder category of the DSM-5.[3] Research diagnostic criteria have been proposed[1] and include evening hyperphagia (consumption of 25% or more of the total daily calories after the evening meal) and/or nocturnal awakening and ingestion of food two or more times per week. The person must have awareness of the night eating to differentiate it from the parasomnia sleep-related eating disorder (SRED). Three of five associated symptoms must also be present: lack of appetite in the morning, urges to eat at night, belief that one must eat in order to fall back to sleep at night, depressed mood, and/or difficulty sleeping.

Cluster Number:
Wiki Number: PW135
Diagnosis: Night Eating Syndrome
US Patients: 1-2%; approximately 10% of obese persons
World Patients:
Sex Ratio:
Age Onset:
Brain Area: Reduced serotonin in the brain may be a factor
Symptoms: lack of morning appetite; urges to eat at night; belief in needing to eat to fall back asleep; depression;    difficulty sleeping
Progression: likely have 25+% of calories consumed after the evening meal; occurs more than twiceor more per week
Causes: The person is fully awake while eating, this is not “sleep-eating.”
Medications:
Therapies: Eating foods high in serotonin (bananas) or tryptophan (turkey) , but these do not affect serotonin or  tryptophan in the brain

Eating disorders among bariatric surgery patients: The chicken or the egg?
by Marissa A Parsons on October 26, 2023
Postoperative eating behaviors and unhealthy weight control measures are leading causes of bariatric surgery complications. Candidates for bariatric surgery and individuals with eating disorders may share common risk factors, such as a history of dieting, and/or being bullied or teased for their weight. Binge-eating disorder, night eating syndrome, and bulimia nervosa are the most common eating disorders among candidates for bariatric surgery before the operation. Malnutrition, stress, and...
Chronotype preference, sleep quality, and night-eating behaviors in patients with metabolic dysfunction-associated steatotic liver disease: Assessing the relationship with disease severity and fibrosis
by Ayse Sakalli Kani on October 12, 2023
CONCLUSION: Despite the non-morningness chronotype demonstrating poorer sleep quality and a higher prevalence of night-eating behavior, our findings revealed no statistically significant differences in terms of sleep quality, nocturnal eating habits, or chronotype preferences among patients with varying degrees of MASLD severity. On the other hand, advanced fibrosis was significantly impacted by poor sleep quality.
Slc12a2 loss in insulin-secreting β-cells links development of overweight and metabolic dysregulation to impaired satiation control of feeding
by Yakshkumar Dilipbhai Rathod on October 11, 2023
Male mice lacking the Na^(+)-K^(+)-2Cl^(-) cotransporter Slc12a2 (Nkcc1) specifically in insulin-secreting β-cells (Slc12a2^(βKO)) have reduced β-cell mass and mild β-cell secretory dysfunction associated with overweight, glucose intolerance, insulin resistance, and metabolic abnormalities. Here, we confirmed and extended previous results to female Slc12a2^(βKO) mice, which developed a similar metabolic syndrome-like phenotype as males, albeit milder. Notably, male and female Slc12a2^(βKO) mice...
Association of participants who screened positive for night eating syndrome with physical health, sleep problems, and weight status in an Australian adult population
by Sai Janani Sakthivel on September 20, 2023
CONCLUSIONS: Several physical health problems were found to be significantly associated with the spNES group including sleep problems, increased BMI, increased levels of pain and lower self-reported physical health-related quality of life. Consequently, future research exploring the complex interaction between NES and these medical conditions may provide further insight into the diagnosis, screening tools and management of NES. Additionally, this study highlights the need for future studies...
