Why is it bad to have a snack?
why is it bad to eat midnight snack?
researchers recently found that when fruit flies stop eating at night, their heart aging can be slowed down. In addition, the researchers also analyzed the specific molecular mechanism.
the Institute found that mice fed a high-fat diet for only eight hours a day were healthier and slimmer than mice fed the same amount of food throughout the day, and the two groups consumed the same amount of calories.
experts point out that not only what to eat, but also what time to eat is important for health. Last year, the group further experimentation, and found that the mechanism of time limitation is more complex than expected. This will reverse the animal model of obesity and diabetes.
on the basis of these studies, the team again found that for Drosophila, eating during the more active time of the day, sleeping at night, gaining weight more slowly, and maintaining heart function better than those who eat at all times.
both groups consumed the same amount of calories and exercised the same intensity. But whether they eat low-fat cereals or high-fat, flies that eat only during the day are healthier than those that eat all day.
in order to solve the genetic mystery, researchers analyzed the gene elements that encode the biological clock, and found that TCP-1 ring complex chaperone and mitochondrial electron transport chain complex are the main regulatory elements in this process.
these studies show that when to eat is also important for our health. Although there is no intervention experiment in human body at present, it is obviously a feasible way to lose weight, and more experiments may reveal what is the primary factor leading to obesity.
previous studies have also shown that for mice already suffering from obesity, restricting their diet so that they can’t eat for more than nine hours can also detect weight loss.
in addition, another group of researchers also found that an important signal system in the brain controls appetite, energy consumption and body fat composition. One of the specific genes: y6, determines the body’s weight.
the researchers found that the y6 knockout mice were smaller and had less non adipose tissue than normal mice. In addition, as mice age, knockout mice grow fatter than normal mice, especially when they eat high-fat food. In this case, mice become obese and appear to have metabolic problems similar to diabetes.
studies show that pancreatic polypeptide is closely related to y6 in mice. This is a satiety signal, which can control the eating situation at different times. The researchers pointed out that taking the same amount of calories at different times had different effects on body weight.
