Stay every night and sleep until late in the is a habit that could threaten for weight gain. People late to bed go and late in the evening, more fast food, less fruit and vegetables eat sleep more calories and weigh more than people, who go to earlier sleep and guards you earlier, according to a new study North-Western medicine.
Late 248 consuming more calories a day, twice as much food and half as many fruits and vegetables than those with previous periods of hibernation, quickly the study. They drank more full-calorie soft drinks. The late the extra calories consumed during dinner and later in the evening when everyone else was asleep. You had also a higher body mass index, a measure of body weight than normal thresholds.
The study is one of the first in the United States relationship between the circadian timing sleeping and waking, to explore dietary behavior and body mass index. The study was published online in the journal obesity and is expected to display in a late summer print issue.
"The extra daily calories can mean a significant amount of weight gain - two pounds per month - if they are not compensated for by more physical activity", co-lead author Kelly Glazer said Baron, a health psychologist and a Neurology instructor at Northwestern University Feinberg School of medicine.
"We don't know whether late consume the extra calories, because they more high-calorie food prefer or because there are less healthy options in the night," lead co-author Kathryn Reid, Research Assistant Professor of Neurology at the Feinberg School said.
The study shows not only the number of calories you eat are important, but also, if you eat - and linked to this is when you sleep and when you wake up, the sleep and circadian rhythms said senior author Phyllis Zee, m.d., Professor of Neurology and Director research program Feinberg and Medical Director of the Sleep Disorders Center at the Feinberg and Northwestern Memorial Hospital.
"Human circadian rhythms synchronized sleep and metabolism in the Earth's daily rotation, so that when the sun goes down you should not eat, sleep," said zee. "If sleep and food are aligned not with the body's internal clock, it can result in changes in appetite and metabolism, which could lead to weight gain."
The research for people might be relevant, which are not very successful in losing weight, Zee said. "The study proposes regulating the timing of the food and sleep could improve the effectiveness of weight management programs," she said.
The results are also relevant for night Schichtarbeiter, at the wrong time of the day related to her body of rhythms food. "It's midnight, but they are eating lunch," said zee. "The risk of obesity and cardiovascular, cerebrovascular and gastro intestinal disorders is higher."
The study included 51 persons (23 late and 28 normal sleepers), which were an average age of 30. Late risers went to sleep an average time of 3:45 am, woke up, ate breakfast at the lunch, lunch around 2:30 pm, dinner 20:15 and a last meal at 10 am, which were normal thresholds on average until 8:00 to 10:45 am, ate breakfast from 9 am, lunch at 1 pm, dinner at 7 am, a last snack at 8:30 am and slept at 12:30 am
Participants in the study included their eating and sleeping in logs and wore a wrist Actigraph, which monitors sleep and activity cycles, for at least seven days.
Late sleepers function in the company of job search where you can their own hours make it Baron pointed out, such as academics or consultants. "they find niches in which they can live this lifestyle, or they just get by with less sleep," she said.
A number of studies plan Northwestern researchers to test the results in a larger community and to understand the biological mechanisms that link the relationship between circadian rhythms, sleep timing and metabolism.
The research was supported Institute for the national institutes of health by the national heart, lung, and blood.
