According to Xinhua News Agency (Reporter Tian Xiaohang) When is eating closely related to metabolic health? The team of Mao Yilei and Yang Huayu from the Department of Liver Surgery of Peking Union Medical College Hospital compared the effects of three meals a day and two time-restricted eating methods on the physical condition of healthy adults, and found that “morning eating” can improve fasting blood sugar, reduce body weight and physical condition It is more effective in improving insulin sensitivity and controlling blood sugar.
Time-restricted eating refers to eating within a specific time period (usually 8 hours) each day, with no calorie restriction during the eating period, and no eating for the rest of the time. Time-restricted eating can be divided into morning eating and noon eating. The former is to control the daily eating time between 6:00 am and 3:00 pm, that is, not eating dinner; lunchtime eating is to control the daily eating time from 11:00 am to 3:00 pm Between 8 p.m., no breakfast. Both time-restricted eating regimens have been shown to benefit metabolism, but previous studies have not adequately compared their effects on human health.
The team of Mao Yilei and Yang Huayu is the first to conduct a clinical trial of time-restricted eating in non-obese healthy people. Ninety healthy volunteers who volunteered to participate in the study were assigned to a morning meal group, a midday meal group, and a control group. In the end, 82 volunteers completed the 5-week trial. The results of the analysis showed that eating in the morning was more effective in improving insulin sensitivity than eating in the afternoon. Morning eating improved fasting blood sugar, reduced weight and obesity, improved inflammation, and increased gut microbial diversity.
The study found that the energy intake of the two time-restricted eating groups was lower than that of the control group, indicating that energy intake can be restricted by shortening the daily eating time. There were no significant differences in energy intake between the two time-restricted eating groups, suggesting that differences in metabolic health improvement between the two groups were not due to differences in energy intake.
The study also found that the two types of time-restricted eating had different effects on the daily rhythm of plasma adipokines and the rhythmic gene expression of peripheral blood mononuclear cells, suggesting that these two different types of time-restricted eating had different effects on the daily rhythm of plasma adipokines and peripheral blood mononuclear cells. Different roles in metabolic health may be related to biological rhythms.
It is reported that the research results were recently published online in the international authoritative journal Nature Communications.
