Maybe you CAN blame being fat on your genes. But there’s a way to overcome that family history – just get three to four hours of moderate activity a day. Sound pretty daunting? Not for the Amish of Lancaster County, Pa., who were the focus of a new study on a common genetic variation that makes people more likely to gain weight. It turns out the variant’s effects can be blocked with physical activity – lots of it.
Scientists believe about 30 percent of white people of European ancestry have this variant, including the Amish, and that may partly explain why so many people are overweight.
But fighting that fat factor may be easier in the Amish community’s 19th century rural lifestyle. They don’t use cars or modern appliances. Many of the men are farmers and carpenters, and the women, who are homemakers, often care for several children.
The researchers found that Amish people with the genetic variant were no more likely to be overweight than those who had the regular version of the gene – as long as they got three to four hours of moderate activity every day. That included things like brisk walking, housecleaning and gardening.
And while physical activity is recommended for just about everyone, the study suggests that people with the gene variation need to be especially vigilant about getting exercise.
