Eating slowly may help you lose weight

Press Trust of India  |  Tokyo 

Trying to shed those extra kilos? Chewing slowly and refraining from for two hours before may help, scientists say.

Changes in habits were strongly associated with lower and weight (BMI), and smaller waist circumference, according to researchers from in

The findings are based on for nearly 60,000 people with in who submitted claims and had regular health check-ups between 2008 and 2013.

The data included information on the dates of consultations and treatments, while the check-ups included measurements of weight (BMI) and waist circumference, and the results of tests for blood chemistry, urine, and liver function.

During the check-ups, participants were quizzed about their lifestyle, including their and sleep habits as well as alcohol and tobacco use.

They were specifically asked about their speed, which was categorised as fast, normal, or slow.

They were asked whether they did any of the following three or more times a week: eat dinner within 2 hours of going to sleep; snack after dinner; and skip breakfast.

More than a third (36.5 per cent) of participants had one check-up over the six years, while just under a third (29.5 per cent) had two. One in five (20 per cent) had three.

At the start of the study, some 22,070 people routinely wolfed down their food; 33,455 ate at a normal speed; and 4,192 lingered over every mouthful.

The slow eaters tended to be healthier and to have a healthier lifestyle than either the fast or normal speed eaters.

Around half of the total sample changed their speed over the course of the six years.

All the aspects of and sleeping habits studied, as well as alcohol consumption and previous obesity--defined as a BMI of 25 kilogrammes per square metres were significantly associated with


After taking account of potentially influential factors, the results showed that compared with those who tended to gobble up their food, those who ate at a normal speed were 29 percent less likely to be obese, rising to 42 percent for those who ate slowly.

Although absolute reductions in waist circumference - an indicator of a potentially harmful midriff bulge - were small, they were greater among the slow and normal speed eaters.

Snacking after dinner and within two hours of going to sleep three or more times a week were also strongly linked to changes in BMI. However, skipping breakfast was not.
