Lack of sleep associated with high-calorie food choices

There’s more science to back up the fact that a good night’s rest is best for your health. A new study by Uppsala University author Colin Chapman, M.Sc., published in the Journal of Food Product Design, found that people who were deprived of sleep overnight consumed more calories and grams of food in a simulated supermarket the next day. Purchased. Lack of sleep leads to elevated blood levels of ghrelin, a hormone that increases hunger. However, there was no correlation between individual ghrelin levels and food purchases, suggesting that other mechanisms, such as impulsive decision-making, may be involved in increased purchases.

What are the findings?

Uppsala University in Sweden is the oldest university in the Nordic countries and offers courses in science and technology, medicine, humanities and social sciences. Researchers at Uppsala University wondered whether sleep deprivation could impair or alter individuals’ food-buying choices, based on well-established trends that impair higher-level thinking and increase hunger. was investigated.

They hypothesized that the effects of sleep deprivation on hunger and decision-making would create a “perfect storm” when it comes to shopping and grocery purchases.

The morning after a full night of sleep deprivation and the morning after a full night of sleep, the researchers gave 14 normal-weight men a fixed budget (about $50). Men were instructed to purchase as many of 40 items as possible, including 20 high-calorie foods and 20 low-calorie foods. Next, we varied the price of high-calorie foods to determine whether complete sleep deprivation affected food-purchasing flexibility. minimized the effect of hunger on

Sleep-deprived men bought significantly more calories (+9%) and grams (+18%) than after a full night’s sleep. The researchers also measured blood levels of ghrelin and found that levels of the hormone were higher after complete sleep deprivation. However, this increase did not correlate with food purchasing behavior.

Their findings provide a strong rationale to suggest that patients with concerns about caloric intake and weight gain should maintain a healthy, normal sleep schedule.

Is there a link between sleep deprivation and weight gain?

A study published in the journal Nature Communications found that sleep deprivation makes us more likely to crave junk food than healthy food. Other studies have linked sleep deprivation with increased appetite.

The results of this study show that sleep deprivation significantly decreased activity in appetite-assessing regions in the brain and increased activity in the amygdala when choosing food desirability. This change in brain activity is further associated with increased desire for weight gain that promotes high-calorie foods following sleep deprivation.
