Lazy? Blame your genes
COUCH potatoes can sit back and relax. Scientists say some people are born to be bone idle.
They believe there is a genetic link to whether we are active or inactive, even at the risk of becoming obese through lack of exercise.
“We have shown it is possible to be genetically predisposed to being lazy,” said Professor Frank Booth, of Missouri university in the US.
“This could be an important step in identifying additional causes for obesity in humans.”
Prof Booth and his team were able to selectively breed rats that were either extremely active or extremely lazy. The tests suggest that genetics could play a role in exercise motivation even in humans, the study in the American Journal of Physiology revealed yesterday.
