Abstract

In spite of the increased attention devoted to the literature and by health ministries, overweight and obesity prevalence continues to increase worldwide [1] . A systematic analysis performed in 2013 referred to the global burden of these conditions, and showed that more than 50% of the world’s 671 million obese people live in 10 countries: the United States, China, India, Russia, Brazil, Mexico, Egypt, Germany, Pakistan, and Indonesia [2] . Additionally, overweight/obesity has unhealthy outcomes such as diabetes, hypertension, and cancer [3] .
