Not all calories are equal and it turns out that during the day when you dine in the evening you can affect the amount you burn – or store it as grease. This is according to a preliminary study published in the journal Current Biologists last week.
Researchers in Brigham and the Women's Hospital found that when people's calorie calories burned 10 percent faster later in the afternoon than late at night. All in all, this could add up to 130 extra calories and that's it without raising his finger.
To discover this, scientists recruited a small team of volunteers from 38 to 69 years old and put them in a lab, where they were kept without a telephone, the internet, watches, and even windows in 37 days. It meant that they had absolutely no way to talk about the weather. Participants also maintained a rigorous timetable, which included their preparation of food, activities and schedules of attention by researchers.
Researchers daily shifted the schedule of the day for four hours to throw out the interaction of the participants' watches in the fire, which led to their circadian rhythm – body processes that follow the 24-hour cycle – to print out with the help of only internal factors. This, say researchers, is equivalent to traveling west through four time zones every day for three weeks.
"Because they were doing the equivalent of a globular circulation every week, the inner clock of their body could not continue and thus oscillated at their own pace," said associate professor Jeanne Duffi, associate professor of medicine at Harvard Medical School, in a statement.
"This allowed us to measure metabolism in all the different biological times of the day."
During the experiment, volunteers were carrying body temperature sensors. High temperature of the core has shown that a person burns more calories. The low core temperature showed the opposite. When data came to light, researchers found that the energy cost for rest was the lowest during the circadian phase, which corresponds late in the morning and early in the morning to the highest level during the circadian phase corresponding to late afternoon / early evening, 12 hours later.
So, what does that mean?
