Chewing food slowly…
Scientists: slow eating will save you from obesity
Yulia Koshkina, Naked Science based on The Guardian: Eating slowly may help prevent obesity, say researchers.
Japanese scientists have presented another study that revealed a link between the speed of eating and body mass index (BMI), as well as waist circumference. Some experts were skeptical of such conclusions.
Statements that fast eating provokes obesity have already been voiced by various groups of scientists. Earlier it was reported that those who eat too fast are more likely to be overweight, suffer from acid reflux (a condition in which acid from the stomach is thrown into the esophagus, that is, against the physiological direction) and earn metabolic syndrome (a combination of various metabolic disorders).
In the latest study published in the journal BMJ Open, researchers from Japan examined data collected during medical examinations of more than 59,700 people between 2008 and mid-2013. Participants were asked seven questions about their lifestyle, including the speed of eating.
The results showed that among those who were used to eating slowly, 21.5% were obese. Among those who ate at an average speed, obesity was diagnosed in 30%, and among those who are used to eating fast – in 45%. The dependence of BMI was also revealed. In the first group, the average BMI was just over 22, in the second – 23.5, in the third – about 25. The size of the waist circumference also increased in proportion to the speed of eating.
"Changing the eating habits of the population through various state educational initiatives and programs can be useful for the prevention of obesity and reducing the risk of non–communicable diseases," the authors of the study explain the value of the study.
It should be noted that the study was conducted only among people suffering from type 2 diabetes, there were few older people in the experimental groups, in addition, the level of physical activity and the amount of food consumed daily were not taken into account. The assessment of the speed of eating was subjective, it was given by the participants of the experiment themselves. In this regard, Ian MacDonald, professor of metabolic physiology at the University of Nottingham, expressed doubt about the results of the study.
"Of course, it is impossible to extrapolate these data, making a conclusion about the dependence of the speed of eating and the development of obesity, no matter how attractive the idea is that those who eat fast are likely to eat more, which leads to weight gain," he said.
However, Tam Fry, chairman of the National Obesity Forum, disagrees with him: "The speed at which many people eat is undoubtedly the cause of obesity. It develops faster in those who eat fast, as they simply do not allow their brain to realize that hunger has already receded. In addition, fast food intake leads to high fluctuations in blood sugar, which can lead to insulin resistance."
Fry recommends that working people turn off their phone, mail during lunch, and preferably leave the office altogether.
