Read on to learn more about night eating syndrome and how it can be treated.
What is night eating syndrome (NES)?
Night eating syndrome is a type of eating disorder. It’s when you wake up from sleep to eat at night or eat excessively after your evening meal.
People with NES feel very hungry after dinner. They may wake up from sleep feeling a strong urge to eat. It may also feel like they can’t go back to sleep without eating.
Nearly 2% of people in the U.S. have NES. We also know that:
NES is more common in people with diabetes or obesity. We don’t completely understand why, but it may be related to disturbed sleep and altered metabolism.
NES can occur alongside another mental health condition, such as depression. It may have to do with sleep issues and an altered circadian clock.
NES is often associated with insomnia because you feel so hungry at night, wake up at night, or can’t go back to sleep without eating.
What are the long-term consequences of NES?
People with NES often eat 25% or more of their total calories at night. They may also eat less — or not enough — during the day.
Eating at night, along with sleep difficulties, can lead to additional health complications. In the long term, it can be associated with being overweight or having obesity, diabetes, or early artery disease.
How is night eating syndrome different from binge eating disorder?
Night eating syndrome isn’t the same as binge eating disorder. Those with binge eating disorder will eat a lot in one period of time, often to cope with depression or anxiety. They may have the urge to eat any time of the day.

On the other hand, people with night eating syndrome only have the urge to eat at night. They may wake up several times to eat at night.
How is night eating syndrome diagnosed?
If you think you may have night eating syndrome, talk with your healthcare provider or a mental health provider. It may be helpful to keep a food and sleep diary to share with your provider during your appointment.
Your healthcare provider will make a night eating syndrome diagnosis based on:
How much of your food intake is at night
How much you eat during the morning and day
Your sleep patterns
Your mood and its association with food intake at night
How much distress the symptoms cause you and how much they affect your life
How long you have been experiencing symptoms
If there are any other factors, such as substance use, medication side effects, or other medical or psychiatric conditions

Treatment for night eating syndrome will usually be a combination of:
Psychotherapy — like cognitive behavioral therapy (CBT) — to help you understand your night eating patterns and give you ways to cope
Antidepressant medications, such as selective serotonin reuptake inhibitors (SSRIs)
Behavioral therapy techniques to help you stop eating at night, such as locking the refrigerator or leaving notes in your kitchen
Light therapy, which can help regulate sleep cycles and help with seasonal affective disorder (SAD)
