Who wants to eat more meat and less fruit — and gain less 
weight? Anyone? Anyone? Paul Williams, a researcher with the Lawrence Berkeley National Laboratory, has some advice: start running. Far. Every day. A news release from the American College of Sports Medicine reports that Williams categorized 106,736 runners by the distance they run each day – fewer than 2 kilometers, 2-4 kilometers, 4-6 kilometers, 6-8 kilometers and more than 8 kilometers — then studied how fat they got when they ate the kind of food that will be served at Thanksgiving.
In the least active group (less than 2 kilometers per day), a runner’s body mass index increased significantly in association with higher meat intake and lower fruit intake; so did the circumference of the men’s waists and women’s waists and hips. In the most active group (more than 8 kilometers per day), the estimated effects of the high-risk diet on body mass index, waists, and hips were reduced by 50 percent or more. And yes, those who ran some distance in between ended up in the middle.
