Genetic Influence for Obesity Linked to a Baker’s Dozen

The impact that our genetic background has on daily metabolism cannot be overstated, as a team of investigators has just discovered that variations within 13 genes can have a considerable influence on how easily an individual can gain or lose weight. This large-scale genome-wide association study (GWAS), overseen by the Genetic Investigation of Anthropometric Traits (GIANT) consortium, is the first to pinpoint genetic variations that may directly impact the function of genes associated with body
