Scientists have obtained unexpected results by studying how many calories the human body burns at different times of the day. It turns out that at rest in the evening people spend 10% more energy than in the early morning. A study on this issue was published by the journal Cell Current Biology.
These findings highlight the important role of circadian rhythm when it comes to affecting metabolism. The new data is also helping to explain why sleep and eating disorders lead to weight gain.
“The fact that the same exercise at different times of the day burns such different amounts of calories was a big surprise to us,” said study author Kirsi-Marja Zitting of the Brighamand Women's Hospital's Sleep and Circadian Rhythm Unit at Harvard University School of Medicine.
To determine changes in metabolic intensity during the day without being affected by physical activity, the cycle of day and night, and diet, the scientists observed seven study participants in the laboratory without telling them what time it was. There were no clocks, no windows, no telephones and no internet in the room. People had to go to bed and wake up at a specific time. Each day this time shifted four hours later, which was the equivalent of traveling west through four time zones each for three weeks.
"Because they virtually circled the globe every week, their internal clocks were not able to work as they did," said study co-author Jeanne Duffy.
It was shown that the least waste of energy by the body at rest was during the biological night, and the greatest - after 12 hours, during the biological evening. Respiratory coefficient, reflecting the degree of absorption of macronutrients, was the lowest biological in the evening and the highest biological in the morning.
“It is important not only what we eat, but also when we eat and rest. All of this affects how much energy we burn and how much fat is stored in the body. Eating and sleeping regularly is very important to overall health,”adds Duffy.
