Night Eating Syndrome
This is a serious disorder, a result of upsets in hormones that regulate sleep, hunger and stress. People with night eating syndrome usually have no desire to eat until the afternoon, then eat most of their calories during the evening and at night, often waking up for high-calorie snacks. They need food to help them sleep. Feeling stressed and depressed is common.
Research suggests it affects 1,5% of all adults and around 10% of obese people. If you think you may have a problem with nighttime eating, get professional help from your doctor.
