A new study in the US suggests that the weight of adults who live close to fast food restaurants may not be that much different to those who don’t. The research by Harvard Medical School, which used data from over 3,000 adults, who entered a heart-health study back in 1971, found no consistent relationship between participants’ driving distance to fast food outlets and their weight over the next 30 years. Dr Jason Block told Reuters: “Maybe proximity is not the thing we should be focusing on. It may be more important to look at why people make their choices they do at restaurants, grocery stores and other food places. You can make healthful choices wherever you go.”
