Vigorous exercise helps you lose weight by making you forget about hunger. [사진=게티이미지뱅크]It has been shown that vigorous exercise helps people forget about hunger. It was especially effective in reducing women’s appetite. This is one more reason why people losing weight should exercise. .
According to the American medical journal ‘Medical News Today’, researchers at the University of Virginia found that vigorous exercise suppresses ghrelin more than moderate exercise, and that this effect may be more pronounced in women.
Ghrelin is a hormone related to appetite. People with high ghrelin levels generally have more difficulty losing weight. According to past research, the reason ghrelin levels rise when dieting is to protect the body from starvation. Anorexia, bulimia, etc. are associated with high levels of ghrelin.
Researchers asked eight healthy men, with an average age of 43, and six healthy women, with an average age of 32, to exercise. The participants’ ghrelin levels were measured before exercise, after moderate-intensity exercise, and after high-intensity exercise. Participants reported their appetite after each exercise session.
“Ghrelin is a hormone released from the stomach that interacts with the hypothalamus, an area of the brain that regulates hunger,” said Kara Anderson of the University of Virginia School of Medicine and lead author of the study. “Female participants had higher total ghrelin levels and DAG form compared to male participants. “We found that ghrelin levels were lower,” he said. There are two types of ghrelin: acylated (AG) and deacylated (DAG). DAG accounts for approximately 80% of ghrelin in the body.
Both men and women showed decreased DAG ghrelin levels after vigorous exercise. He said, “High-intensity exercise can suppress hunger more than low-intensity exercise,” and “Women’s AG type was significantly reduced after high-intensity exercise.”
“We all know the beneficial effects of exercise,” said Mir Ali, director of the Weight Loss Center at Orange Coast Medical Center in California. “It’s difficult to draw firm conclusions because of the small number of participants.” He said, “Proteins and vegetables tend to suppress appetite for a long time,” and “You should reduce the intake of simple carbohydrates and sugars that are easily broken down.”
