Chronic Sleep Deprivation tied to Overwight and Obesity

A recent review of the literature on sleep deprivation, energy balance, and weight regulation reveals that chronic sleep deprivation is linked with obesity.  Over 35 percent of American adults are obese and more than 28 percent sleep less than six hours a night. While weight loss strategies generally focus on diet and exercise, modifying total lifestyle and routine, including sleep behaviors, is integral to helping to manage weight.

Sleep deprivation can impacts a person in several capacities hormonally: reduced insulin sensitivity, increases in circulating ghrelin, and decreases in circulating leptin.  The two latter are the hormones that regulate appetite and our hunger/satiety cues.  This shows that on a hormal level this lack of sleep plays a role in increased appetite.  Researchers are pursuing as to how this impacts fat adiposity as well.

Make developing good sleeping habits a focus of your new year.  It will help with weight control and stress management.  ...Not bad for a New Year's resolution that focuses on adding something for better health and not taking away.
