Regular exercise can counter obesity genes, and make you thinner

While genes may influence our likelihood of being overweight or obese, a new study has found that a physically active lifestyle can blunt the effects of inherited obesity genes.
Regular exercise can substantially decrease the genetic effect of a major fat mass and obesity associated gene FTO on body weight, the findings showed.
“This provides a message of hope for people with obesity predisposing genes that they can do something about it. Our body weight destiny is not only written in our genetic blueprint,” said one of the researchers David Meyre from McMaster University in Ontario, Canada.
