Partial sleep deprivation linked to obesity

Philadelphia, PA, October 24, 2012 – Evidence linking partial sleep deprivation to energy imbalance is relevant to weight gain prevention and weight loss promotion. A new study published today in the Journal of the Academy of Nutrition and Dietetics bases this finding on an extensive review of literature published over a fifteen-year period.

More than 35 percent of American adults are obese and more than 28 percent sleep less than six hours a night. While weight-loss strategies incorporate lifestyle changes focusing on diet and exercise, modifications in an individual's daily routine, including sleep behaviors, can help manage weight.

"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."

The research team evaluated articles published between 1996 and 2011 to determine the role of partial sleep deprivation on energy balance and weight regulation. As part of its methodology, the team constructed a series of comparative tables detailing individual study populations, study designs, energy intake, energy expenditure, and measurements of the hormones ghrelin, leptin, insulin, glucose, and cortisol. Analysis of these characteristics identified a set of patterns, including reduced insulin sensitivity, increases in ghrelin, and decreases in leptin among partially sleep-deprived individuals. Changes in ghrelin and leptin influenced energy intake among the study populations.

"Changes in these hormones coinciding with an energy-reduced diet paired with changes in response to partial sleep deprivation may be expected to increase ghrelin and decrease leptin concentrations even further to promote hunger," says Dr. Nickols-Richardson.

The paper calls for further research to determine the effects of sleep deprivation on body composition and substrate use and suggests evaluation of an individual's sleep patterns combined with regular, sufficient sleep may benefit healthy weight management.


Interesting but have you got the ideas round the wrong way?

GMO food damages our kidneys (Seralini 2012) which causes obesity (standard knowledge) and lack of sleep.

In turn this can lead to diabetes.

My own anecdotal experience was to lose the ability to sleep and suffer from bleeding.

Cured or helped by years of good non gmo food difficult to achieve and my waistline is reducing again, more hours of good sleep etc.

We are heading rapidly not into danger but beyond.

25 per cent annual risk for Alzheimers for my genetic makeup every year.

47 per cent pre diabetes

Swing from men at a low level to 3 times as much Multiple Sclerosis as previously (pre gmo days)

35 per cent obesity in USA.

In fact the USA holds the record for about 50 illnesses and clinical conditions and for the GMO food growing.

Is their a link?

Pollack, Olney, Pusztai, Ermakova, Seralini and hundreds of others have been warning us of GMO harm every year since 1971.

Indicidual regulators with no degrees or any knowledge of science deny this research and the health of USA is explicit for all to see.

35 per cent obesity and blame the patient.
