A new study shows that fast food is associated with overeating

According to a new study accepted for publication in The Endocrine Society, Journal of Clinical Endocrinology & Metabolism (JCEM), a meal too fast compared to slow, not only limits the release of hormones in the intestine causes sensation automatically. The release of these hormones decrease often leads to overeating. "Most of us have heard that eating quickly can cause overeating and obesity, and in fact, some observational studies have supported this idea," said Alexander Kokkinos, MD, PhD, Laiko General Hospital in Athens, Greece, and the principal study. "Our study provides a possible explanation of the relationship between speed of eating and overeating, showing that the speed at which a person can eat, release intestinal hormones that affect the brain signal to stop eating too much. "

In recent years, research on gut hormones, such as peptide YY (PYY) and glucagon-like peptide (GLP-1) showed that their release after a meal affects the brain and induces satiety and termination of meals . Until now, concentrations of the appetite regulatory hormones have not been studied in relation to the different speeds of the feed.

In this study, the subjects are the same test meal, consumed 300 ml of ice cream at different prices. The researchers collected blood samples to measure glucose, insulin, blood lipids and gut hormones before lunch and 30 minutes after the start of the meal until the end of the session later, 210 minutes . The researchers found that subjects took the full 30 minutes to complete the ice had higher levels of PYY and GLP-1 and also tend to have a better appreciation of the fullness.

"Our results provide insight into an aspect of modern life, too, namely the fact that many people have expressed the demand for labor and living conditions, fast food and in greater quantity than in the past, "says Kokkinos. "The warning was given to us as children, that" Wolfing your diet, you are fat, "is actually a physiological explanation.
