As per study results if the food is eaten slowly by pausing between bites and chewing slowly could lead to weight loss.
There was a research conducted involving sixty thousand Japanese people displaying a link between eating slower or faster and losing or gaining weight.
A research duo of the Kyushu University—Japan, wrote in the BMJ Open journal that altering the eating speed could affect the changes in obesity, waist circumference and BMI.
Pauses targeted at lessening the eating speed may prove effective in preventing obesity and reducing the linked health risks.
Body Mass Index (BMI) is a ratio of weight-to-height which is used for learning whether a person is within the healthy range category or not. The World Health Organization (WHO) has demarcated the BMI 25 as overweight and 30 or above as obese.
In accordance with the Japanese Society for the Study of Obesity, a BMI of 25 was considered as obese for the research study conducted for the Japanese populations.
The researchers did the analysis on the health insurance data of 59,717 individuals who are diagnosed with Type-2 Diabetes Mellitus—a disease that generally hits in adulthood because of being overweight.
The participants of the research study had regular check-ups from 2008 till 2013.
Data that was taken by these participants include their age, BMI, waist circumference, gender, eating habits, blood pressure, tobacco use and alcohol consumption.
The results indicated that the slow-eating group of four thousand one hundred and ninety-two had a smaller on an average waist circumference, a mean BMI of 22.3 and lesser obese individuals which makes 21.5 % of the total.
More than 44% of the fast-eating group was found obese with a mean BMI of 25.
The team also noticed the alteration in the eating speed over the timeframe of six years. They found that the decrease in eating speeds could lead to a reduction in obesity and BMI.
Other factors that could assist in losing weight, as per the data, includes not eating within two hours of going to bed and no snacking after dinner.
Skipping breakfast did not have any apparent effects.
The limitations of the study are that eating speed and other behaviours of the people were self-reported. Also, there was no data about the quantity of food the participants ate or about whether they exercised or not.
Simon Cork—Imperial College of London while commenting on the research said the research confirms what we already believe in that eating slowly leads to less weight gain in comparison to eating at a quicker pace.
This could be because the satiety signal takes time to travel to the brain from the stomach and may reach only when the fast eater has already consumed more than they need.
Katarina Kos—an obesity researcher—Exeter Medical School said that similar research needs to be conducted in non-diabetic people for learning the potential of the diabetes medication in weight loss or gain.
