Night Eating Syndrome is a form of compulsive eating. Sufferers eat a lot at bedtime and often get up during the night to eat. The food that is consumed may be quite unusual and is often high in calories. Leftovers in the fridge may be eaten. Entire desserts may be eaten. Odd concoctions may also be prepared, including salt or sugar sandwiches, flour, and other inedible substances. The food is eaten quickly, and the binge episodes typically last less than 10 minutes. The episodes typically occur nightly but may occur more than once during the night. The next morning after binging a person will feel full and have a poor appetite. There is typically no or only partial memory of the night’s events, but they may wake to discover the kitchen is a mess. Not only can this binging behavior lead to unwanted weight gain, it may also be significantly disruptive to sleep.
Night eating syndrome affects an estimated 1.5% of the population, and is equally common in men and women, according to the National Institute of Mental Health. Night eating syndrome is not the same as binge eating disorder, although individuals with night eating syndrome are often binge eaters. It differs from binge eating in that the amount of food consumed in the evening/night is not necessarily objectively large nor is a loss of control over food intake required.

Medical Impact of Night Eating Syndrome

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. Those who are obese increase their risk of heart diseases, many types of cancer and gallbladder disease.
Individuals with night eating syndrome often have a history of substance abuse, and may also suffer from depression. They typically report being more depressed at night. They also frequently have sleep disorders.
Many people find themselves eating late at night, even when they aren’t hungry.
Nighttime eating can cause you to eat more calories than you need and lead to weight gain.
