It goes without saying that our nation currently faces a serious obesity crisis. Nearly half of the United States has an obesity prevalence greater than 30% and not a single state in the U.S. shows a prevalence less than 20% (Fig. 1). This pervasiveness of obesity has led to a dramatic spike in cardiovascular disease and type II diabetes cases, which has ultimately decreased the quality of life and life expectancy for many Americans (1). One solution to this nationwide problem is weight loss, particularly diet-induced weight loss (2). Even a 5% reduction in body weight is shown to improve fasting blood lipid and glucose concentrations while decreasing the risk of all-cause mortality (3, 4). Indeed, weight loss is beneficial and is needed to combat our on-going battle with obesity. However, the loss of body mass without considering changes in body composition is irresponsible. Though beneficial for metabolic health, weight loss is shown to decrease bone mass (5) which could, in turn, increase the risk of osteoporosis and skeletal fracture.
