In our society it is not only commonplace for people to burn the candle at both ends but it is even revered as a respectable trait. Is there any connection between these poor sleep habits and the epidemic levels of obesity in our society?

A UCLA study published in the journal Psychoneuroendocrinology suggests a clear connection between poor sleep patterns and hunger. It turns out that sleep-deprivation causes an increase in a hunger stimulating hormone called “ghrelin” and a decrease in another hormone called “leptin“– an important hormone in the regulation of both appetite and metabolism . It is no surprise that nighttime eating is commonplace among the overweight and obese.

It is important to note that these, and other, hormones are directly connected to the part of the brain that is responsible for subconscious control of eating and metabolism. When these hormones are out of balance, hunger and eating are difficult to control. self-control is little help in such a situation. Appetite control as well as reaching your weight loss goals are dependent on healthy sleep patterns. 

A recent study discovered that a single night of poor sleep resulted in insulin resistance. As you may already know, insulin resistance can promote diabetes and weight gain. In fact, when the body is resistant to insulin, weight loss is nearly impossible . This and many other studies prove the interconnectedness of the body . You simply cannot ignore the importance of a good night’s sleep, especially when weight loss is your goal.

Sleep researchers suggest getting a minimum of 7 hours of sleep every night. For the best rejuvenation, it is recommended that you try to get to sleep before 11 pm. If possible, try not to eat at least 3 hours before bed. This will allow the body to dedicate its resources towards repair and rejuvenation rather than digestion and assimilation. Look for a good weight loss blog or weight loss podcast for more information about how sleep can impact weight loss and insulin resistance.
