Lifestyle can alter gene activity, lead to insulin resistance
July 6th, 2008
A Finnish study of identical twins has found that physical inactivity and acquired obesity can impair expression of the genes which help the cells produce energy. The findings suggest that lifestyle, more than heredity, contributes to insulin resistance in people who are obese. Insulin resistance increases the chance of developing diabetes and heart disease. The study, "Acquired obesity and poor physical fitness impair expression of genes of mitochondrial oxidative phosphorylation in monozygotic twins discordant for obesity," appears in the online edition of the American Journal of Physiology-Endocrinology and Metabolism, published by The American Physiological Society...
