Slow eating key to weight loss

Posted February 14, 2018

Researchers wanted to see how eating speed over time, and a range of other eating behaviours, affected people's likelihood of being obese.

The researchers observed the data from 60,000 people who have diabetes over a six-year period.

'Eating quickly also causes bigger blood sugar fluctuations which can lead to insulin resistance.

What did the research involve?

The study's overall subjects were 59,717 individuals diagnosed with Type 2 diabetes - a chronic condition that affects those in adulthood who are overweight.

Further, switching from a fast to a slow eating pace could help decrease BMI, according to the researchers. (East Asian people tend to have smaller body sizes than European people, which is why the BMI threshold for obesity is different).

"It may encourage a more reflective eating style and reduce the risk of overconsumption, ' said Jebb, who was not involved in the Kyushu study, in a comment to the Science Media Centre".

What were the basic results?

The fast-eating group had also larger waistlines on average than their peers in the other two groups. "Those who naturally eat slowly may be attending to their body's cues for fullness, and eat a more appropriate portion during each eating occasion", Nina Crowley, Ph.D., a registered dietitian nutritionist and health psychologist working at the Medical University of SC, told CBS News.

The researchers found that at 15 months, the mean BMI z score was nonsignificantly lower in the intervention arm (mean difference, -0.075; 95% CI, -0.183 to 0.033; P =.18) in baseline adjusted models. But they are a good reminder that how and when people eat can be as important as the foods they choose, she adds.

Scoffing your food too quickly increases the risk of becoming overweight, research suggests. The research also points out that avoiding after-dinner snacks and not eating within two hours of going to bed can also help when it comes to maintaining a healthy weight.

The study involved almost 60,000 Japanese people, and the results showed that the slow-eating group had a smaller average waist circumference, a mean body-mass index of 22.3 and fewer obese individuals.

The study didn't assess people's socioeconomic group, which might have had an effect.

The verdict: eat slow and enjoy your meals, stop living your life on fast forward and take your time to savor the delish in your dish. This may mean that people's relative levels of deprivation could affect the results.

The results reveal that 21.5% of the slow-eating group was obese, compared to nearly 30% of the normal-speed group and 45% of the fast-eating group. Normal eaters made up the majority at 33,455, while just 4,192 people said they were slow eaters.

There may be limits to how the findings apply to the United Kingdom, in terms of the population diet, lifestyle and risk factors for obesity. Prevalence of obesity according to the United Kingdom threshold (BMI 30) is much lower in Japan. "The speed at which a lot of people wolf down their food is undeniably a contributor to obesity", he said (via The Guardian).
