Our fast-paced lifestyles are making us fat
Eating too quickly won’t just give you indigestion – it could also pile on the pounds, new research suggests.
Scientists believe eating quickly stops the release of a hormone that tells the brain when the stomach is full, so people who bolt down their food are more likely to overeat than those who dine at a more leisurely rate.
Professor Stephen Bloom, of Imperial College, London, who worked on the study, said the findings meant that the trend for busy office workers to snatch meals at their desk rather than taking time to eat properly could be contributing to the obesity epidemic.
‘Speed-eating, eating at work or when you’re doing spreadsheets on the screen so that you keep stuffing food into your face are likely to increase the risk of obesity,’ he said.
For the Greek-led study volunteers ate ice cream at different rates. Blood levels of glucose, insulin, lipids and gut hormones were measured before and after consumption of the ice cream.
Participants who took 30 minutes to finish the ice cream had higher concentrations of the gut hormones peptide YY and glucagon-like peptide and also tended to feel more full than those who took less time to eat the ice cream.
