The biological clock in the organism is controlled by the clock gene. The cycle of the circadian clock is slightly different from the 24 hours a day, but the body is corrected by light and diet to form a circadian rhythm. Earlier studies have found that circadian clock disorders can lead to obesity and diabetes. The animal experiment led by Professor Wadada, a professor at Waseda University, shows that regular diet helps prevent obesity. This achievement will be officially announced at the 11th Annual Meeting of the Obesity Society of Japan.
The team fed mice 3 times a day, then tested the clock function of the kidney and liver in mice and investigated the rhythm of the circadian clock. It was found that if the mice were fed at the time of 7 o’clock, noon and 19 o’clock, the longest non-feeding period of the day between the dinner and the next day’s breakfast was the long period of fasting. After that, breakfast can make the body clock “calibrate” and play an important role in “calibrating” the rhythm of the day’s activities.
If the dinner time is postponed to 22, the mouse circadian clock will deviate by 2 to 3 hours. The research team believes that this is because the interval from lunch to dinner is almost the same as the interval from dinner to breakfast, which causes the circadian clock to be disordered. If the dinner is divided into two at 19 o’clock and 22 o’clock, the deviation of the biological clock will be shortened to 1.5 to 2 hours.
