China News Service, Beijing, March 11th. Many people's weight loss starts with "don't eat dinner", and some people take "no food after lunch" as their own way of keeping healthy.
Is "no food after lunch" healthy?
Is there any scientific basis for it?
A recent study by doctors at Peking Union Medical College Hospital said that skipping dinner is more beneficial to metabolic health.

A growing body of research shows that the biological clock not only regulates work and rest, but is also closely related to metabolic health and the risk of chronic disease.
On February 22, the team of Mao Yilei and Yang Huayu from the Department of Liver Surgery of Peking Union Medical College Hospital published a research paper entitled "Randomized Controlled Trial of Time-restricted Eating in Non-obese Healthy Volunteers" in Nature Communications, a sub-journal of Nature.
According to reports, time-restricted eating refers to eating within a specific time period (usually 8 hours) each day, without calorie restriction during the eating period, and not eating the rest of the time.
Time-restricted eating can be divided into morning eating and noon eating.
Morning eating is to control the daily eating time between 6 am and 3 pm, that is, not eating dinner; lunch eating is to control the daily eating time between 11 am and 8 pm, that is, do not eat dinner. Eat breakfast.
Both morning and midday meals have been shown to have metabolic benefits, but previous studies have not adequately compared the effects of these two TRF regimens 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.
The research team recruited 429 volunteers, and screened 90 healthy volunteers who volunteered to participate in the study and assigned them to the morning eating group (30 people), the lunch eating group (30 people) and the control group (30 people). middle.
The results of the study 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 no significant differences among the three groups in blood pressure, circulating lipid concentrations, glycated hemoglobin, high-sensitivity C-reactive protein, sleep quality, or appetite.
Energy intake was reduced in both time-restricted eating groups compared to the control group.
Explain that energy intake can be restricted by shortening the daily eating time.
The study also found that the different effects of two different types of time-restricted eating on metabolic health may be related to biological rhythms.
This randomized controlled clinical trial by Mao Yilei and Yang Huayu's team showed that eating in the morning showed greater benefits on insulin resistance and related metabolic parameters than eating in the afternoon.
Time-restricted eating is an intermittent fasting method that controls the time of eating to earlier in the day, that is, skipping dinner, which is more conducive to metabolic health.
