We’ve all been there…your friend finds out you’re studying to become a registered dietician and before you know it, you’re bombarded with how-to’s and how-comes and why this and why that. You exclaim the usual: diet is key and make sure to exercise regularly. But how many of us forget to emphasize the importance of a good night’s rest? After all, the Centers for Disease Control and Prevention state that adults should sleep 7-9 hours per night. At this point you may have asked yourself, “Why is this so necessary in regards to weight loss?” Well, I’m glad you asked…
The Journal of the Academy of Nutrition and Dietetics recently published a research review discussing the effects of partial sleep deprivation on weight gain prevention and weight loss promotion. The article stated that “partial sleep deprivation is associated with an increased sense of lethargy”, therefore causing energy expenditure to decline. Having lost a few hours of sleep will lead to additional time awake, which could result in eating an extra meal. Declined energy expenditure and increased energy intake is definition weight gain! But it doesn’t end here. The article also stated that “ hunger and satiety are regulated by metabolic and hormonal signals indicative of energy status and perturbation of these signals may cause energy imbalance and excessive energy intake,” meaning your very own hormones are sending distressed signals that can unknowingly cause you to overeat throughout the day. This all sounds like a perfect storm. These are just a few out of the many issues concerning sleep deprivation but they sure are enough to convince me to get my sleep on!
