Obesity is possibly slightly linked to partial sleep deficiency; Research

Partial Sleep deprivation is possibly linked to obesityResearchers have found that partial sleep deficiency is related to the obesity.

This research has been published online in the Journal of the Academy of Nutrition and Dietetics.

Researchers in this study worked on an extensive review of literature published over a fifteen-year period from 1996 to 2011. They made comparative tables showing the study populations, study designs, energy intake, energy expenditure, and measurements of the hormones ghrelin, leptin, insulin, glucose, and cortisol.

They found that more than 35% of American adults are obese and more than 28% sleep less than six hours a night.

Researchers have also found that the increased levels of Ghrelin – a hunger stimulating hormone – and decreased levels of leptin – a hormone playing an important role in energy intake and energy expenditure – are affected during the sleep resulting in increased appetite.

“Various investigations, although diverse, indicate an effect of partial sleep deprivation on body weight management,” says lead investigator Sharon M. Nickols-Richardson, PhD, MD, professor, Department of Nutritional Sciences, The Pennsylvania State University, University Park. “The intriguing relationship between partial sleep deprivation and excess adiposity makes partial sleep deprivation a factor of interest in body weight regulation, particularly in weight loss.”

Experts are of the opinion that such studies tell us that changing some of the daily routines such as sleep behaviors can help us in managing weight. However, this study needs further research.
