When you hear the term “night eating syndrome,” you may picture someone sleepwalking from their bedroom to the kitchen and eating large amounts of food without remembering it in the morning.
Well, that’s not night eating syndrome.
Why? For starters, people with night eating syndrome are conscious when they’re eating and usually eating snack-sized portions. There’s a lot more to this complicated, and commonly misunderstood, condition.
Night eating syndrome is an eating disorder, characterized by repeated episodes of eating excessively at night (after dinner) or after you’ve gone to sleep. This syndrome is diagnostically classified as “Other Specialized Feeding or Eating Disorder”, otherwise known as OSFED. It is a clinical condition that can lead to obesity and result in associated complications such as high blood pressure, diabetes and high cholesterol.
But what is night eating syndrome exactly? Let’s explore some unique characteristics:
1). Night eating syndrome is not the same as binge eating disorder. While there are some parallels – feelings of shame and guilt around eating episodes – they are two separate conditions. A key distinguisher of night eating syndrome is the time of day (late evening and during the night) that eating occurs, while binge eating can occur at any time of day. The quantity of food consumed is typically less than with binge eating disorder and people with night eating syndrome do not experience a loss of control during eating, which is a hallmark of those who binge eat. Individuals with night eating syndrome can wake up several times throughout the night, with hopes that eating will help them fall back asleep.
2). One doesn’t eat much, or may not be hungry, during the day. For someone with night eating syndrome, most food consumption occurs in the late evening. They rarely eat much during the day and consistently lack an appetite in the morning or afternoon. Often 25% or more of total daily caloric intake occurs after dinner-time. .
3). Night eating is a conscious act. Individuals with night eating syndrome are aware of and remember their eating episodes. There is often a belief that they have to eat to fall back asleep. Many affected individuals have sleeping issues or insomnia. Those with night eating syndrome do not suffer from nocturnal sleep-related eating disorder, commonly known as sleep eating.
4). Not all individuals with night eating syndrome are overweight. There is data to suggest that night eating syndrome affects 6-16% of all clinically obese individuals, however not everyone with night eating syndrome is overweight. It can occur among those of all body shapes and sizes and is estimated to effect 1.5% of the general US population.
5). Co-occurring conditions are common. Like other forms of eating disorders, night eating syndrome is often accompanied by substance abuse issues, as well as an increased occurrence of depression, stress and sleep disorders. Frequently, people awake in the night with feelings of irritability, anxiety or stress. Eating occurs as a means of managing these emotions and there is rarely a sense of enjoyment with the food.
6). Night eating syndrome can impact all ages. This syndrome occurs most frequently among young adults, and rarely presents in childhood. Many young individuals begin their night eating behavior during college. Even working professionals are affected, including those who might commonly skip lunch breakfast or lunch during the day.
7). There’s a secretive nature. Most people with night eating syndrome eat in secret and may be prone to hide food. These habits may not impede one’s social ability or relationships with others.
