The Connection Between Sleep and Weight-Loss

Although humans sleep for up to one third of their lives, the function of sleep has yet to be definitely clarified.

We have written about the importance of getting a good night’s sleep many times.  A recent study published in the Annals of Internal Medicine, concluded the following:  “Sleep restriction results in an insulin-resistant state in human adipocytes. Sleep may be an important regulator of energy metabolism in peripheral tissues.”

Translation: Lack of sleep was associated with reduced insulin sensitivity in human fat cells, meaning it can slow or prevent fat-loss or perhaps even cause fat gain.  And, it should be noted that just one week of sleep restriction has negative effects on insulin sensitivity and glucose tolerance in healthy adults.  During the “sleep restriction” phase of the study, their fat cells showed a 30% lower response to insulin.

“Although evidence supports a role for sleep in learning, memory, and other central nervous system functions, prospective epidemiologic studies have found that insufficient sleep may increase the risk for metabolic disturbances, including insulin resistance, obesity, and type 2 diabetes,” according to Josiane L. Broussard, PhD, from Cedars-Sinai Medical Center in Los Angeles, California, and colleagues. “Consistent with the epidemiologic evidence, well-controlled laboratory studies in healthy adults have shown that repeated partial sleep restriction has adverse effects on systemic insulin sensitivity and glucose tolerance, further supporting the hypothesis that sleep may be important for peripheral metabolism.”

In Turbocharged we explain the importance of insulin control and the factors that influence it.  Once again, this study shows that for fat-loss and optimal health, it is not just diet that you need to adjust.  There are other factors like hydration, body composition, activity, strength training, stress reduction and sleep.  In order to experience rapid benefits and transformation, you need to address all the basics.  TurboCharged offers a roadmap to accomplish this in just 8 simple steps.
