Are you in the habit of snacking in the middle of the night? Besides leading to unhealthy eating behaviours, it can also result in poor sleep and obesity, according to a new study.
The research showed that poor quality of sleep seemed to be a major predictor of junk food cravings, and it was associated with a greater likelihood of participants reporting obesity, diabetes and other health problems. “Laboratory studies suggest that sleep deprivation can lead to junk food cravings at night, which in turn leads to increased unhealthy snacking at night, which then leads to weight gain,” said Michael A. Grandner from Department of Psychiatry in the University of Arizona.
“This connection between poor sleep, junk food cravings and unhealthy night time snacking may represent an important way that sleep helps regulate metabolism,” Mr. Grandner added.
A phone-based survey conducted for this study, presented at the 32nd annual meeting of the Associated Professional Sleep Societies LLC in Baltimore, analysed data from 3,105 adults. The results showed that about 60% of the participants reported regular night time snacking and two-thirds reported that lack of sleep led them to crave more junk food.
The team also found that junk food cravings were associated with double the increase in the likelihood of night time snacking, which was associated with an increased risk for diabetes.
