Burning calories becomes essential when we want to lose a few pounds. Diet and sport have a major contribution, but also a certain time of the day. And that's because burns are more intense at this time and you can take advantage of this for weight loss.
A new study shows that there is, however, a time of day when the body naturally burns most calories, and this is due to the circadian rhythm that controls the internal clock of the body and the day-night cycle. These rhythms influence calorie burning, especially in rest periods, where the human body can burn 10% more calories in the late afternoon and evening afternoons, compared to early morning. More specifically, almost 130 calories are burned in the afternoon and evening without the slightest effort, and this can have an impact on health.
The study published in the Journal of Current Biology highlights the fact that the circadian rhythm dictates not only the desire to rest, but also the complexity of the metabolism that operates over a 24-hour period. Thus, people who have an irregular sleep schedule, including those who work in the shifts, face obesity and are prone to develop conditions such as type II diabetes, cancer or cognitive decline. Even if we do not hear it, the biological clock works constantly.
"It is possible that when you eat and energy consumption needs are low, this activity can lead to weight gain," said Jeanne Duffy, a citizen of the study at Brigham and Women's Hospital.
When the most calories burn
The study looked at seven men, both women and men, aged between 38 and 69 who, for 37 days, stayed in a glass-free, hourglass, telephone or Internet lab so that he does not know what time of day he is out. Every evening, the participants went to sleep four hours later than the previous night, this habit lasting for 3 weeks. In this way, the internal clock of the body was forced to keep pace, the researchers noticing that the body's biological periods were completely different from daytime.
Everyone who participated in this study had to wear sensors to measure their body temperature, allowing the researchers to determine the period of most calories. The higher the body's temperature, the more calories it burns. Thus, it was discovered that the calorie burning rate was lower at night when body temperature dropped, while 12 hours later the burned calories rate increased in the afternoon.
Of course, even if you schedule your meals and take care to respect this program, remember that another very important aspect is exercise. Even if you do not go to the gym, every effort, every movement, involves getting the energy, and to ensure even the smallest movements, from the lifting of the arm to the sweeping through the house, burns a necessary number of calories.
