Earlier research has shown that more than one-third of USA adults get 6 hours or less of sleep each night - less than the recommended 7 to 9 hours, according to the study.
GETTING an extra 20 minutes' sleep each night can help boost weight loss, a study suggests.
86 percent of individuals who received sleeping advice increased time spent bed and also a half increased their sleep interval.
"The fact that extending sleep led to a reduction in intake of free sugars, by which we mean the sugars that are added to foods by manufacturers or in cooking at home as well as sugars in honey, syrups and fruit juice, suggests that a simple change in lifestyle may really help people to consume healthier diets", said principal investigator Wendy Hall, from the Department of Nutritional Sciences at King's College London.
So if you're trying to get healthy or trying to lose a bit of weight, maybe start off seeing just how much kip you're getting and work from there.
After carrying out this study, they reduce their unhealthy sugars intake by 10kg equivalent, which is also the equivalent of half a slice of cake with icing, or three chocolate digestives.
Majority were able to increase the amount of time they slept by between 52 and 90 minutes a night through measures such as avoiding caffeine before bed, relaxing in the evening and not eating too much or too little before they put their heads down.
The study involved a group of adults who typically slept for less than the recommended minimum of seven hours.
As a result, the trained half stayed in bed for 55 minutes longer and slept for an extra 21.
Participants kept sleep and food diaries and wore wrist motion sensors to detect how long they slept for.
There was no difference in the control group.
The team suggested that any new sleep routine will take some time to get used to.
A new study showed that person who follows "lack of sleep" formula naturally chooses healthier foods within a week, eating on average 10 grams less sugar every day.
Lead researcher, Haya Al Khatib, added: "Sleep duration and quality is an area of increasing public health concern and has been linked as a risk factor for various conditions".
This isn't the first study to link diet and sleep.
She added: "We hope to investigate this finding further with longer-term studies examining nutrient intake and continued adherence to sleep extension behaviours in more detail, especially in populations at risk of obesity or cardiovascular disease".
