Obesity – Despite effective diets – from low-carb to intermittent fasting – cases of obesity are on the rise. American scientists have now proved in a practical experiment: 1.2 hours more sleep corresponds to 270 kilocalories less energy consumption per day.
The study states, “There is well-established evidence that regularly sleeping less than seven hours a night is associated with negative health effects. In particular, there is increasing recognition that insufficient sleep is an important risk factor for obesity.” Is.” However, it has not been calculated yet.
Scientists at the University of Chicago conducted a study between the beginning of November 2014 and the end of October 2020 on 80 subjects, 41 of whom were men. All participants had a body mass index (BMI) between 25 and 29.9. A BMI over 30 is considered obese. The participants, average age 29.8 years, typically slept less than 6.5 hours per night.
Half of the group were encouraged to get as much sleep as possible at night for 8.5 hours. Weight, energy intake, energy expenditure and sleep duration were monitored using technical means. Subjects lived their normal lives as usual, abstaining from dieting.
“The more sleepy group showed a significant reduction in energy intake (less than 270 kilocalories per day) compared to the control group. There was no significant effect of this ‘treatment’ on energy expenditure (…). Improvement or maintenance of healthy sleep In the long term the duration may be part of obesity prevention and weight loss programmes,” the analysis said.
The study by Esra Tasli from the University of Chicago, published in the Journal of the American Medical Association (JAMA Internal Medicine), is currently the most widely read current scientific study by doctors in the United States.
