You can run away from your fat genes, and you can waltz right on by a hereditary risk of gaining weight. But it’s a little less clear that mimicking funky moves in front of a video game console will protect you from a genetic vulnerability to becoming obese.
So finds a new study that identifies six ways people with unlucky bits of DNA can stave off the accumulation of excess pounds.
Years of research have revealed that inheritance — the fine print transmitted in our DNA — accounts for somewhere between 21 percent and 84 percent of the average person’s propensity to become obese. So if there is one takeaway from genetic studies of obesity, it’s this: Even if your parents saddled you with a passel of fat genes, there’s still plenty you can do to counter their influence.
But what, besides a lifetime of ascetic eating, actually works?
The new study finds that exercise does — and it gets very specific about which forms of regular exercise can ward off obesity in those with more than their fair share of the gene variants that make excessive weight gain more likely.
