Research shows daily walk helps beat “obesity genes”

The Los Angeles Times “Booster Shots” blog reports that a study to be presented at an American Heart Association meeting “shows that people who are genetically prone to obesity can offset that influence by half by walking briskly one hour a day.”

Investigators “looked at more than 7,700 women enrolled in the Nurses’ Health Study and more than 4,500 men in the Health Professionals Follow-up study.”

HealthDay reports that “genes that have been linked to obesity boosted weight by 0.13 kg/m-squared.”

Participants “who briskly walked an hour a day had a 0.06 kg/m-squared decrease in the genetic effect.”

Meanwhile, “for each two hours a day people spent watching TV, the BMI went up by 0.03 kg/m-squared.”
