Night eating syndrome -

Night Eating Syndrome may cause acid reflux and may contribute to dental cavities particularly if individuals go back to sleep without brushing their teeth.

Signs that a family member may be suffering from Night Eating Syndrome include missing food, crumbs and wrappers in the bed, messes in the kitchen in the morning, and regular sleep disturbance. The exact cause of Night Eating Syndrome is not known. As with other eating disorders, there is likely an interplay between genetic and environmental factors.

Stress, negative mood, and anxiety are a few known triggers, as is weight suppression. People with NES seem to have a disruption in their circadian rhythm. A habit of staying up and eating late at night—common among college students for example—could play a factor.

Daytime dieting likely plays a role in the development and maintenance of night eating syndrome. When a person restricts their food intake during the day, the body is in a state of deprivation.

This may drive increased eating later in the day when defenses are down and the urge to eat becomes overpowering. The body needs food and will override attempts at restriction.

Our toxic culture perpetuates the belief that thinness is the key to happiness and success. You might feel desperate to maintain or lose weight. However, if you are waking at night to eat, or staying up late and eating, it might be time to get off the diet train and stop restricting.

Our caring therapists can support you with our non-diet HAES-aligned CBT-based approach. Cognitive behavioral therapy CBT is an effective treatment for Night Eating Syndrome. We usually ask people to keep food and sleep logs to gather more information. We work to modify patterns of eating and sleep.

Regularly eating breakfast and increasing food consumption earlier in the day is key. This helps to reset the circadian rhythm. Over time, eating patterns and hunger will shift earlier and more closely line up with periods of peak activity. Of course, this is often challenging for patients with Night Eating Syndrome.

It will require consistently eating a morning meal, even when not hungry. Once a person with NES is eating greater amounts earlier in the day, we can work on addressing commonly held beliefs that maintain the disorder.

We use cognitive restructuring to address the belief that one will not be able to go to bed—or return to sleep—without eating. We will often work on trying strategies other than eating to encourage a return to sleep and run behavioral experiments to see what might work.

After an episode of night eating, we will help you to show yourself compassion We will conduct a behavioral chain analysis to identify steps in the chain that led to the eating and the consequences. Breaking this apart can help identify ways to navigate similar situations differently in the future.

e We can also work on stress management and the curation of other coping or soothing skills that can be used in lieu of food. Sleep hygiene strategies , including the maintenance of a consistent bedtime and wake-up time, are other strategies we use. Breaking a pattern of night eating can be challenging because eating—generally a positive activity—has reinforced the behaviors of waking up and looking for food late at night.

Another useful strategy can include making a list of reasons not to engage in night eating and reading it before going to sleep. Sometimes, in order to break the pattern, it is necessary to block access to food at night temporarily.

These can include not keeping food in the bedroom and shutting doors between the bedroom and the kitchen. But it cannot be emphasized enough that strategies such as these will not work—and should not be used—if a person is still undereating during the earlier parts of the day.

Because of the circadian rhythm—a biological component that impacts night eating syndrome—sometimes antidepressants and other medications for sleep can help with NES.

Bright light therapy disorder applied during the morning, which is thought to reset circadian rhythms and is used for Seasonal Affective Disorder, is being investigated as a potential treatment. It might help to reset the body clock.

You might want to try waking earlier, getting exposure to morning sunlight, and eating breakfast as an early intervention.

Two books are available on the topic of night eating syndrome—one targeted towards individuals grappling with the condition, and the other designed for healthcare professionals.

These resources provide a deeper understanding of the condition. It should be noted that neither of these books are HAES R -aligned so we recommend getting help from a HAES professional. If you or someone you know suffers from Night Eating Syndrome in California, our therapists can help.

There are many theories surrounding the development, prevalence, and cognitions of NES, however, a firm understanding of this disorder has been difficult to ascertain.

Night eating syndrome -

There is little evidence in support of the use of psychiatric medication for the treatment of eating disorders overall. But there is some support for doing so in the case of NES, where the circadian rhythm disruption suggests a larger biological component.

Medications that have been studied and used include selective serotonin reuptake inhibitors SSRIs such as paroxetine Paxil , fluvoxamine Luvox , and sertraline Zoloft. There are two books on night eating syndrome, one for people who have the condition and one for healthcare professionals. These books may provide more insight into the condition if you or someone you know is struggling:.

Treatments for night eating syndrome often use cognitive behavioral therapy and related techniques. Other strategies that can be helpful include phototherapy, psychoeducation, and medications. If you are experiencing symptoms consistent with night eating syndrome, you may be feeling ashamed and reluctant to find treatment.

They eat even when they are not hungry and continue eating even when they are uncomfortably full. Feeling embarrassed by the amount they eat, they typically eat alone to minimize their embarrassment. They often feel guilt, depression, disgust, distress or a combination of these symptoms.

Those with night-eating syndrome eat a majority of their food during the evening. They eat little or nothing in the morning, and wake up during the night and typically fill up on high-calorie snacks.

Traits of patients with night-eating syndrome may include being overweight, frequent failed attempts at dieting, depression or anxiety, substance abuse, concern about weight and shape, perfectionism and a negative self-image.

Causes of night eating syndrome vary, but there are usually a variety of contributing factors. Sometimes college students pick up the habit of eating at night and are unable to break the habit when they become working adults. High achievers sometimes work through lunches, and then overcompensate by eating more at night.

Night eating syndrome, ironically, may be a response to dieting. When people restrict their intake of calories during the day, the body signals the brain that it needs food and the individual typically overcompensates at night. Night eating may also be a response to stress.

Those with night eating syndrome are often high achievers, but eating patterns can affect their ability to socialize or manage work-related responsibilities. They may also have different hormonal patterns, resulting in their hunger being inverted so that they eat when they should not and do not eat when they should.

Individuals with night eating syndrome are often obese or overweight, which makes them susceptible to health problems caused by being overweight, including high blood pressure, diabetes and high cholesterol.

Additionally, NES often co-occurs with eating disorders, anxiety, depressive, and substance use diagnoses. It is also considered that growing up with a history of trauma or food insecurity can be associated with NES symptoms.

There is minimal research on effective treatments for Night Eating Syndrome, however, a few studies have been conducted that indicate pharmacological treatment and Cognitive Behavioral Therapy CBT may be promising in reducing NES behaviors [4].

Many researchers have suggested that a combination of the two is most effective. Studies also indicate that mindfulness skills such as progressive muscle relaxation can be helpful [4].

Regardless of how far research has to go to understand and effectively treat Night Eating Syndrome, the key for those struggling now is to seek support from eating disorder professionals that can adapt effective eating disorder treatments to their NES behaviors.

Recognizing NES in a Family Member Signs that a family member may be suffering from Night Eating Syndrome include missing food, crumbs and wrappers in the bed, messes in the kitchen in the morning, and regular sleep disturbance.
Signs & Symptoms of Night Eating Syndrome	The neuroendocrine study included 12 night eaters and 21 control subjects. Behavioral study subjects were observed for 1 week on an outpatient basis, and neuroendocrine study subjects were observed during a hour period in the hospital. Main Outcome Measures The behavioral study measured timing of energy intake, mood level, and sleep disturbances. The neuroendocrine study measured circadian levels of plasma melatonin, leptin, and cortisol. Results In the behavioral study, compared with control subjects, night eaters had more eating episodes in the 24 hours mean [SD], 9. They averaged 3. None of the controls ate during their awakenings. Conclusion A coherent pattern of behavioral and neuroendocrine characteristics was found in subjects with NES. Night-eating syndrome NES , characterized by morning anorexia, evening hyperphagia, and insomnia, was described in by Stunkard and colleagues. Since , NES has not been subjected to careful clinical study, but its prevalence has been estimated at 1. This report describes 2 related studies designed to characterize NES. The behavioral study attempted to define the behavioral characteristics of the syndrome in terms of timing of energy consumption during eating episodes, level of mood throughout the waking hours, and frequency of nighttime awakenings. The neuroendocrine study attempted to characterize the syndrome in terms of circadian profiles of plasma melatonin, leptin, and cortisol levels. The behavioral study was conducted from January to June on an outpatient basis in the Weight and Eating Disorders Program of the Department of Psychiatry of the University of Pennsylvania School of Medicine, with the approval of the institutional review board of the University of Pennsylvania. Subjects were recruited by announcements in local newspapers that asked for volunteers with morning anorexia, evening overeating, and insomnia. Candidates for the study were interviewed by 1 of us G. Exclusion criteria were serious physical or emotional illness, including diabetes mellitus and other endocrine disorders; use of psychotropic medications, steroids, diuretics, or hypnotics; excessive consumption of alcohol; a concurrent eating disorder; participation in a weight reduction program; or an occupation that involved night shifts or other unusual time requirements that interfered with meals. The use of tobacco, caffeine, and illegal drugs was not assessed. Subjects consisted of 8 women and 2 men, all of whom were overweight. A control group of 10 overweight subjects, matched for sex, age, and weight with the night eaters, was recruited from persons who applied to take part in the study but were found not to manifest signs of NES. To compare the size of the ingestions, particularly at night, with the binges reported by persons with bulimia nervosa, we enrolled 4 subjects with bulimia nervosa who followed the standard protocol. At the beginning of the study, subjects were given motion sensors and instructed in their use. After the completion of 1 week of data collection, the motion sensors were collected and analyzed for nighttime awakenings. Records of food consumption were analyzed for energy and macronutrient content. The hour food intake data were collected for 1 week. Since data for the first and last days of the week sometimes did not include the full 24 hours, 5 days of complete data were analyzed graphically by examining the cumulative energy intake from 6 AM to AM the next morning. Data were analyzed using generalized estimating equation 8 , 9 regression models, which accommodated the dependence between the multiple measurements for each subject and allowed separate line segments for the daytime and nighttime periods for night eaters and controls. The effect of status night eaters or controls on cumulative energy intake throughout the 24 hours was tested using this model. A piecewise regression using generalized estimating equations was also used to assess the significance of the difference between night eaters and controls in level of mood throughout the 24 hours, as well as the slope of the mood of the night eaters after 4 PM. A Poisson distribution, also fit using generalized estimating equations, assessed the significance of the difference between night eaters and controls in the number of nighttime awakenings. A Wilcoxon test was used to compare age differences between night eaters and controls. The average number of eating episodes, amount of kilojoules consumed per episode, and nighttime awakenings of the 4 women with bulimia nervosa are reported, but, because of small sample size, data comparing them with the night eaters and controls are not. In both the behavioral and neuroendocrine studies, data are reported as mean SD if not otherwise stated, and all P values are 2-tailed. The body mass index BMI of the night eaters was The ages of the night eaters The amount of food intake by night eaters and controls differed only moderately. By contrast, the night eaters had 9. While the food intake of the controls slowed markedly by 8 PM, that of the night eaters continued at a rapid pace until after 12 AM. Figure 1 also shows that, during the 24 hours, the average mood of the night eaters 5. Furthermore, after 4 PM, the mood of the night eaters fell at a rate of 0. Nighttime awakenings were far more common among the night eaters 3. The carbohydrate content of this food intake was The ratio of carbohydrate to protein in the snacks was None of the 13 awakenings of the controls was associated with food intake. Subjects with bulimia nervosa averaged 6. None reported nighttime awakenings. The neuroendocrine study, conducted in the Clinical Research Department and the Laboratory of Gastroenterology of the University Hospital, Tromsö, Norway, from May through August , investigated circadian neuroendocrine patterns of subjects with NES. The study was conducted with the approval of the Ethical Committee of Region V, Norway. Night eaters were recruited, as in the behavioral study, by announcements in local newspapers. Twelve night eaters and 21 control subjects, all women, were selected by 1 of us G. Subjects were admitted to the Clinical Research Center at 8 AM after an overnight fast. They remained for 24 hours, during which time they were free to move about until 11 PM, when they went to bed. Four meals of kJ each were served at 8 AM, 12 PM, 4 PM, and 8 PM. Shortly after admission, a blood sample from fasting subjects was drawn from an indwelling catheter, and blood was drawn every 2 hours thereafter. Melatonin was measured with a commercial kit, and lipid extraction of the samples was performed. Intra-assay and interassay precisions were Leptin was measured using a commercial kit, and intra-assay and interassay precisions were 2. Cortisol was measured using a commercial immunoassay kit, and intra-assay and interassay precisions were 5. Blood glucose was measured by a glucose analyzer. Insulin was measured by radioimmunoassay. Every effort was made to control and equalize exposure to light. For this purpose, subjects were admitted to the Clinical Research Center in groups of 4. Subjects slept in a room designed to exclude any outdoor light. As an additional precaution, nighttime blood drawings were carried out with the aid of a small flashlight while the subjects' eyes were covered. Statistical analysis of the differences between groups in plasma melatonin, plasma cortisol, plasma insulin, blood glucose, and incremental plasma leptin values after subtracting the levels at baseline, 8 AM during the hour observation period were evaluated by repeated measures multivariate analysis of variance. A Wilcoxon rank sum test was used to compare age differences and the time of the highest and lowest plasma concentrations of melatonin, leptin, and cortisol. The 12 night eaters were divided into 7 nonobese BMI, The BMI of the 10 nonobese control subjects was No subject reported having been diagnosed as having sleep apnea and no episodes of sleep apnea were observed during the studies in the clinical research department. As in the behavioral study, the nighttime awakenings were far more common among the night eaters 3. Dysregulation of the circadian levels of melatonin, leptin, and cortisol was found among the night eaters and not among members of the 2 control groups. There were no differences in plasma cortisol levels between overweight and normal-weight subjects, either among night eaters or controls. The weight groups were combined accordingly for comparison of night eaters with controls. The preprandial and postprandial blood glucose and plasma insulin levels did not differ between night eaters and controls among either the overweight or normal-weight groups. This study revealed a surprising coherence of the behavioral and neuroendocrine patterns of persons selected on the basis of morning anorexia, evening hyperphagia, and insomnia. Persons selected on the basis of these minimal criteria were found to manifest not only sleep-onset insomnia but, quite unexpectedly, nighttime awakenings during half of which food was ingested. This distinctive circadian pattern of behavior was associated with a similarly distinctive pattern of mood disturbance. Contrary to the usual pattern found in depression, the mood of the night eaters fell during the evening. The circadian neuroendocrine findings included attenuation of the usual nighttime rise in melatonin and leptin as well as elevated levels of plasma cortisol. Night-eating syndrome appears to represent a new eating disorder, different from the established disorders of anorexia nervosa, bulimia nervosa, and binge eating disorder. It differs from the latter 2 disorders in the frequency and size of ingestions, particularly at night. In contrast to the very frequent night eating of persons with NES, Greeno et al 11 reported that only 6 of 40 patients with binge eating disorder ever ate at night and did so only once a week. The size of ingestions by the night eaters kJ is far smaller than that of patients with bulimia nervosa kJ whom we studied, than that reported by Rosen et al 12 kJ , by Rossiter and Agras 13 kJ , and by patients with binge eating disorder reported by Grilo and Schiffman kJ. The carbohydrate-rich It has been reported that this pattern of eating increases the availability of tryptophan for transport into the brain and conversion into serotonin, 16 , 17 resulting in facilitation of sleep. Night-eating syndrome appears to differ also from the "nocturnal sleep-related eating disorders" reported by sleep disorder clinics and characterized by eating upon awakening from sleep, often in association with sleepwalking and related sleep disturbances. The relation between these disorders and NES is unclear, in part because of uncertainty regarding the nature of the former disorders. Thus, they have been reported either mostly in infants 18 or mostly in adults, 19 - 21 primarily during sleep 18 , 19 or primarily during wakefulness, 20 , 22 and with 18 , 19 , 21 or without 20 polysomnographic evidence of parasomnias. These inconsistencies may contribute to the uncertainty regarding their prevalence. For example, Schenk and Mahowald 19 , 22 reported only 38 0. As noted above, the criterion for the time of onset of night eating differed between the behavioral and neuroendocrine studies to accommodate the different supper times in Philadelphia and Tromsö, Norway. Supper occurs even later in the Mediterranean cultures but NES is still defined there as overeating following the evening meal. These considerations make it appropriate to establish the onset of night eating as that which occurs after the end of the evening meal rather than by hour of the day Table 1. The minimal criteria used to define NES identified not only persons with eating disorders but also those with sleeping and probably mood disorders. The criteria also identified persons with a distinctive neuroendocrine pattern: attenuation of the usual nocturnal rise in melatonin and leptin levels and an elevated level of cortisol throughout the day. There is an intriguing concurrence between the salient neuroendocrine findings—attenuation of the nocturnal elevation in melatonin and leptin—and the salient behavioral findings of nighttime awakenings, often linked with eating. Melatonin appears to induce and maintain sleep. Attenuation of the nocturnal rise in leptin may also contribute to the nighttime awakenings and the associated food intake. Leptin levels rise at night, 30 and Sinha et al 31 have proposed that this rise suppresses appetite and helps to maintain sleep, but Matkovic et al 32 suggest that attenuation of this rise prevents adequate suppression of appetite. The latter sequence may have occurred in night eaters in this study, with the breakthrough of urges to eat and the resultant disruption of sleep. The attenuation of the nocturnal rise in leptin and melatonin may be related through the agency of corticotropin releasing hormone CRH , which suppresses the secretion of melatonin. First, the lack of a nocturnal increase in leptin removes the leptin-mediated inhibition of CRH, resulting in an increase in levels of CRH. In the study, 1 however, intensive, long-term psychotherapy of 20 night eaters revealed that NES occurred during periods of life stress and, significantly, was alleviated with reduction of the stress. The limitations of this report should be noted. The studies involved a small number of subjects and were conducted in different settings with different patients. The behavioral data were collected on an ambulatory basis during 1 week in which subjects had access to food at night. The neuroendocrine data were collected in a clinical research department during a hour period in which the last meal was eaten at 8 PM. The distribution of ages and body weights of subjects in the 2 studies did not differ significantly, however, and, with 4 exceptions, all subjects were women. In the neuroendocrine study, it is possible that the restriction of nighttime food intake may have stressed the night eaters and affected the neuroendocrine results. However, in our experience, night eaters do not persist in their usual eating patterns in the hospital. It was thought that our design of 4 small meals was most likely to reveal circadian patterns. The concurrence between the behavioral and neuroendocrine findings suggests that NES is a sufficiently robust phenomenon to be identified despite the limitations noted in this report. Data from future behavioral and neuroendocrine studies should, however, be collected from the same population. Delineation of a new syndrome raises the question of treatment, and features of NES suggest potentially fruitful approaches. Thus, the presence of a sleep disorder linked to attenuation of the nighttime rise in melatonin suggests administration of exogenous melatonin. The night eating related to attenuation of the nighttime rise in leptin might be corrected by the administration of exogenous leptin. Subjects' ingestion of high-carbohydrate snacks suggests an attempt to improve sleep and mood by raising levels of serotonin; selective serotonin reuptake inhibitors might more readily achieve this goal. Measures to control stress may be useful in alleviating NES. More modern pharmacotherapy, such as the use of CRH receptor antagonists, may be added to the old prescription of psychotherapy. full text icon Full Text.
