Scientists have connected the speed of an expense of calories with time of day


Scientists under the leadership of Jean Duffy from Harvard University have said that passive wasting of energy a body of the person depends on circadian rhythms. As reports N 1, researchers have established that least of all calories in the awake condition of rest are burned during biological night, and most of all - during biological day. during the research scientists watched

13 volunteers who within 37 days lived in laboratory without external light sources, electronic devices and hours. Each of volunteers kept to a strict diet and a daily routine. In the first three days of an experiment people lived under protocol 24 in days with the prolonged time in a bed - about 16 hours. Then volunteers were divided into two groups: six have continued to live according to the 24-hour schedule (control group), and for sleeping of seven people every day shifted withdrawal for four hours, stretching thus them days till 28 o'clock.

as a key indicator of metabolism researchers used the volume of carbon dioxide which the body makes at breath and also the speed of oxidation of fats and carbohydrates. It has been as a result established that the lowest consumption of energy a body which is at rest, occurs during approach of internal night, and the biggest - about 12 hours later, after a while after awakening.

Should noting that it up to 70% of daily burned calories is spent for maintenance of biological functions, necessary for survival of an organism: breath, activity of a brain and regulation of body temperature.
