US News and World Report - "An Answer In Your Genes?" - Arlene Weintaub
Despite the ongoing debate about the value now of using genetic data to guide weight loss, several companies have started marketing gene tests to insurers and employer groups, and sometimes to consumers. Some scientists who specialize in genetics argue that the link between genes and weight loss isn’t strong enough to justify testing for most people. About 175 genetic variants have been associated with body weight to date, and most of them are still not well understood, said Ruth Loos, PhD, professor of environmental medicine and public health, director of obesity and related metabolic traits program at the Charles R. Bronfman Institute of personalized medicine at the Icahn School of Medicine at Mount Sinai. What’s more, studies of twins and families have suggested that body weight is determined half by genetics and half by lifestyle factors. “Even people who carry genetic variants are able to overcome them,” with extra effort, Dr. Loos added.
