The discovery was made possible thanks to a group of volunteers who lived for more than a month in the lab without doing any exercise.
Instead there were no windows or clocks, so they did not know what time it was, and the feed crew fed them every day at the same time.
The results showed that the energy consumed by the human body at rest depends on the heart rate. The body burns more calories if the biological clock shows it is in the afternoon. More calories are burned depending on the amount of food swallowed.
The findings show how important is the 24-hour clock for metabolism, which is responsible for regulating the body's physiological rhythm, as well as the hormones our body consumes at a certain time, such as cortisol, estradiol or renin
Dr. Anne Duffy, who is in charge of the study, notes that to improve the results of a diet, the most important thing is to prevent caloric intake at the end of the night and in the early hours of the morning.
"Let's say we get up two or two hours early and eat breakfast an hour or two before," says the expert. "We can eat breakfast not only while our bodies are not prepared to deal with it, but while we need less energy to maintain our functions, then the same breakfast can cause additional storage calories because we do not need them to maintain the functions of Our bodies, "he said.
