Sleep deprivation also led to increased blood levels of ghrelin, a hormone that increases hunger, on the following morning; however, there was no correlation between individual ghrelin levels and food purchasing, suggesting that other mechanisms — such as impulsive decision making — may be more responsible for increased purchasing<\/strong>.<\/p>\n Researchers in Sweden were curious as to whether sleep deprivation may impair or alter an individual’s food purchasing choices based on its established tendency to impair higher-level thinking and to increase hunger.<\/p>\n “We hypothesized that sleep deprivation’s impact on hunger and decision making would make for the ‘perfect storm’ with regard to shopping and food purchasing — leaving individuals hungrier and less capable of employing self-control and higher-level decision-making processes<\/strong> to avoid making impulsive, calorie-driven purchases,” said first author Colin Chapman, MSc, of Uppsala University.<\/p>\n On the morning after one night of total sleep deprivation, as well as after one night of sleep, Chapman, along with Christian Benedict, PhD, and their colleagues, gave 14 normal-weight men a fixed budget (approximately $50). The men were instructed to purchase as much as they could out of a possible 40 items, including 20 high-caloric foods and 20 low-calorie foods<\/strong>. The prices of the high-caloric foods were then varied to determine if total sleep deprivation affects the flexibility of food purchasing. Before the task, participants received a standardized breakfast to minimize the effect of hunger on their purchases.<\/p>\n Sleep-deprived men purchased significantly more calories (+9%) and grams (+18%) of food than they did after one night of sleep<\/strong>. The researchers also measured blood levels of ghrelin, finding that the hormone’s concentrations were higher after total sleep deprivation; however, this increase did not correlate with food purchasing behavior.<\/p>\n “Our finding provides a strong rationale for suggesting that patients with concerns regarding caloric intake and weight gain maintain a healthy, normal sleep schedule<\/strong>,” said Chapman.<\/p>\n Follow up studies are needed to address whether these sleep deprivation-induced changes in food purchasing behavior also exist under partial sleep deprivation, though. Additional research should also look into sleep deprivation’s potential impact on purchasing behavior in general<\/strong>, as it may lead to impaired or impulsive purchasing in a variety of other contexts.<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":" From the Wiley media release: People who were deprived of one night’s sleep purchased more calories and grams of food in a mock supermarket on the following day in a… Read more »<\/a><\/p>\n","protected":false},"author":5,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[321,10,95,336,43],"tags":[],"_links":{"self":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/15428"}],"collection":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/comments?post=15428"}],"version-history":[{"count":1,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/15428\/revisions"}],"predecessor-version":[{"id":15442,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/15428\/revisions\/15442"}],"wp:attachment":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/media?parent=15428"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/categories?post=15428"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/tags?post=15428"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"sleep](\"http:\/\/therapytoronto.ca\/news\/wp-content\/uploads\/2013\/07\/sleep-deprivation.jpg\")
<\/a>People who were deprived of one night’s sleep purchased more calories and grams of food in a mock supermarket on the following day<\/strong> in a new study published in the journal Obesity<\/em>, the official journal of The Obesity Society.<\/p>\n
