Only 5 days of fast food can lead to obesity in your mind

Ultra -treated foods and calories, such as chocolate or chocolate potatoes, play an important role in the development obesity. However, so far its effects on the brain have not been clear. A recent research published in the magazine Nature metabolism Discover a sudden discovery: even Short -term consumption From these few healthy foods it can significantly reduce Insulin sensitivity in the brain One of the healthy people.

Stephanie Coleman, professor of metabolic nervous source at the University of Tabinga, in Germany, reveals an article in Conversation “he An important role for the brain in the development of obesity“.

As shown, in healthy people, insulin helps Control of appetite in the brain. However, “in obese people, insulin loses its ability to regulate eating habits, causing insulin resistance.”

In the brain, insulin “too It indicates the body that eats less Coelman says, by reducing eating, from here the importance of this research, which separates how “people who suffer from an insulin resistance experience in the brain. More desire From food More abdominal fat“.

In addition, the study reveals that “less sensitive signs of insulin in the brain can be observed A long time before we talk about obesity“This is, it is not necessary to have a body mass index greater than 30 to resist insulin in the brain.

In experience, researchers can check this.After only five days To consume additional 1500 calories, consisting of chocolate and fried potatoes, insulin sensitivity in the brain’s brain has been reduced significantly. “It is strange, as Coleman says, these symptoms have previously been observed only in obesity.

This resistance to insulin brain can be observed in Magnetic resonance Even a week after participants are made their normal diet. Although there is no significant increase in weight, “the short period was long enough to allow You will increase that liver fat Greatly. “

According to the main author of the study, “obesity does not return to poor diet and lack of exercise. Air conditioning insulin response to the brain To short -term changes in the diet before there is an increase in weight. “

When correcting insulin resistance in the brain, Coleman notes that there are studies that show this Regularly During a specific period, insulin sensitivity in the brain is re -sensitive in weight and obesity, so “this can also be assumed that it can also be applied to people with normal weight.”
