Can I eat at night?
Scientific and standardized health concept, it is not recommended to eat too late.
There are two kinds of eating disorders at night. One is that people eat when they are sleepwalking or half asleep. They usually don't realize what they are doing, so when they wake up, they may find the bed full of candy wrappers, but they don't remember eating candy.
Another common eating disorder is night eating syndrome, in which patients mainly eat at midnight. According to a research article in the Journal of the American Medical Association, as of 6 pm, people with night eating syndrome consumed one-third of their daily calories, while people who ate a normal diet consumed almost three-quarters. However, from 8 pm to 6 am, people with night eating syndrome will consume 56% of their daily calories, while people who eat normally only consume 15%. Almost 100 people have 1 2 people with night eating syndrome.
In the 1950s, Dr. Albert J. Stuckard, a psychiatrist at the University of Pennsylvania, first described the disease. Researchers recently found that night eating syndrome is related to weight gain. 9%- 14% of obese people and 27% of severely obese people have night eating syndrome. Night eating syndrome can also affect people's mental health. In a study conducted in psychiatric clinics in Pennsylvania and Minnesota, 12% of patients suffered from night eating syndrome. The study also found that eating at night is more addictive than other problems.
Another study shows that people with night eating syndrome are more likely to suffer from all kinds of depression. Generally speaking, depression is more obvious every morning, but people who eat at night are more likely to be depressed at night. At present, it is not clear what causes the night eating syndrome, nor why it leads to depression and addiction. One theory is that night eating syndrome interferes with hormones that regulate sleep, appetite and mood. Because the food eaten late at night is mostly snacks rich in carbohydrates, such snacks will make people feel very comfortable to eat. According to this theory, night eating syndrome is a way of self-treatment.
