Is your weight gain caused by a lack of sleep?
The lack of sleep and its relationship to gaining weight has been the subject of a great deal of research in recent years. In a study published in the American Journal of clinical nutrition, researchers believe they have found an explanation to this question. They used MRI scans on individuals who slept four hours a night for six nights in a row.
After completing the MRI, these people were shown pictures of food. During the viewing, the areas of the brain that responded to pleasurable activities increase to a greater degree than when they slept nine hours.
The scientists believe that this increased brain activity leads to a high potential of overeating.
Other researchers discovered that a lack of sleep might cause weight gain because it affects the appetite hormones within the body.
