Several studies have revealed that sleep deprivation can lead to obesity because it is associated with decreased levels of leptin (a hormone that controls body weight and metabolism). As well as increased levels of ghrelin (which plays a role in increasing appetite).
A study involving 1088 pairs of twins found a gene linked to obesity and observe how it relates to sleep patterns. These genes affect how the body uses energy, how fat is stored in the body, feeling of fullness after eating, and how quickly the sugar is used.
These observations are found, the less time sleeping, these genes affect the body more. Genetic influences on body mass index was two times greater in people who sleep less than seven hours. Compared to the nine hours of sleep each night.

"The results showed that sleep deprivation lead to a more permissive environment for expression of genes related to obesity. Or maybe sleep longer it protects from stress-related gene expression of obesity," said Dr. Nathaniel Watson, leader of the study.
He said the new results are preliminary. However, it can be shown that weight loss will be effective when genetic influences on obesity be reduced by sleeping longer.
