Slow down: People who wolf down their food treble their risk of being overweight

If you're wondering why your waistline is expanding, don't watch what you eat. Watch how you eat.

Those who wolf down dinner apparently treble their risk of being overweight.

Scientists suggest the modern manner of eating too quickly - and until absolutely full - is a significant factor in the obesity epidemic.

Such eating habits pile on the pounds much more than expected, even taking into account the amount of calories consumed, the scientists found.

They suspect the joint impact of eating fast and until full overrides signals in the brain which would normally encourage a little more self control.

A study published today in the British Medical Journal Online First blames the couch potato lifestyles of fast food, larger portions, TV dinners and the demise of family mealtimes for contributing to the problem.

Professor Hiroyasu Iso and colleagues from Osaka University, Japan, carried out a study involving 3,200 Japanese men and women aged 30-69 years between 2003 and 2006.

Those participating were sent a diet history questionnaire. Half of the men and 58 per cent of the women said they normally ate until they were full.

Just under half of men and a third of women said they ate quickly.

The group of participants who said they ate 'until full and ate quickly' had a higher body mass index or BMI, the scoring system that measures obesity levels.

They also had a higher total energy intake than those who did not 'eat until full and did not eat quickly'.
