Does not getting enough sleep make you gain weight?
Research has shown that lack of sleep may be a potential contributor to weight gain and the growing obesity epidemic due to the fact that it causes disruptions to a number of hormonal and metabolic processes. Some studies have shown that sleep deprivation can lead to increased appetite as the levels of hormones that regulate hunger (specifically leptin, which tells the brain when we’ve eaten enough, and ghrelin, which triggers feelings of hunger) are affected by a decrease in sleep. In fact, a newly published study (in October 2012) in the Annals of Internal Medicine looked specifically at the effect of sleep deprivation on fat cells and found that a lack of sleep actually results in an insulin-resistant state, suggesting that sleep may in fact play an important role in energy metabolism.
In reviewing and citing several studies, the National Sleep Foundation suggests that 7-9 hours of sleep per night is optimal for most adults.
