Female loser in fighting appetite

When faced with favorite foods, women are inferior to the macho wing in their ability to control appetite. This trend makes the rate of obesity in women always higher than men

Scientists have long wanted to learn mechanisms to control the amount of food taken in the brain. Gene-Jack Wang, an expert working at Brookhaven National Laboratory (USA) and colleagues wanted to find out why some people often overeat and gain weight, while many others rarely feel appetite.

They invited 13 women and 10 fast-gaining men to take a test. The team asked volunteers to provide information about the foods they liked and asked them to eat them in large quantities in one night.

The next morning scientists teach volunteers how to control appetite with psychotherapy. They then showed the volunteers their favorite dishes and then conducted brain scans. All volunteers admitted that psychotherapy helped them control their appetite, but the results of the brain scan showed that the areas that control feeding behavior in the female brain continued to signal with frequency. high. Meanwhile, the activity of the male brain is greatly reduced.

Nora Volkow, a member of the research team, said the big difference between the two sexes surprised her. The scientist speculated that the nutritional needs of women were always greater than men, because they had to store nutrients for their children. Therefore, the brains of the sisters are "programmed" to order the body to eat whenever they see their favorite foods, even when their stomachs are full of food.

The team said they will continue other tests to see if the specific hormones of women have a direct impact on the areas of the brain that control eating behavior.

"In modern society, food is sold everywhere, and ads about them also appear in the media. So our brains are always in a state of temptation. Understanding the brain's response to food will help us find a way to stop cravings, " Nora said.
