Lack of Sleep Has a Risk of Being Overweight

“Who sleeps dine” confirms a recent study by the University of Leeds that sleep deprivation promotes weight gain.

In this study, 1615 adults aged 19 to 65 years, 57% of whom were women, described their sleep patterns and responded to food questionnaires over three to four days. The objective was to analyze the associations between sleep duration, diet and markers of metabolism in adults.

The results showed that people who sleep less than six hours a night are more likely to gain weight: they had an average of 3 cm waist more than those who slept nine. Conversely, a longer sleep was associated with a lower body mass index (BMI) and a better metabolic profile. Insufficient sleep can therefore contribute to the development of metabolic diseases such as diabetes.

Why is short sleep associated with obesity and diabetes? One of the explanations is that lack of sleep influences food choices and pushes for preferring foods high in energy.However, this study did not show any link between insufficient sleep and poor dietary choices. It seems rather to suggest that it is the lack of sleep in itself that promotes weight gain.

Other studies have shown that the length of sleep on working days decreased by about 37 minutes between 2002 and 2010. This factor could therefore play an important role in the epidemic of overweight and obesity.

For Laura Hardie, one of the authors who writes in The Telegraph“because we found that adults who reported sleeping less than their peers were more likely to be overweight or obese, our results underline the importance of Sleep well enough. The amount of sleep we need differs between people, but the current consensus is that seven to nine hours is the best for most adults.
