The researchers recruited 42 healthy volunteers with normal weight who slept less than 7 hours a day and randomly divided them into two groups. The first group was given suggestions to help improve their sleep habits, such as avoiding caffeine and going to bed when they are full or hungry. The second group served as the control group.
As a result, in the first group, 86% people spend more time lying in bed and 50% people spend more time sleeping. According to the diet records, with the prolongation of sleep time, after a period of time, the volunteers in the first group naturally reduced their intake of sweets and carbohydrates, and the average daily sugar intake decreased by nearly 10g compared with the beginning of the study. There was no similar change in the control group.
The Daily Telegraph quoted Wendy Hall, the research director, as saying: "Long sleep leads to a decrease in the intake of' free' sugar, which refers to the sugar added to food by manufacturers or families and the sugar contained in honey, syrup and juice, which means that simple lifestyle changes may indeed help people eat healthier."
Previous studies have shown that lack of sleep may change the hormone level that controls appetite, which will greatly increase people's appetite, prefer a high-calorie diet and increase the risk of obesity.
