ABSTRACT
Obesity and overweight are chronic disorders of multifactorial origin which can be defi ned as an increase in the accumulation of body fat (FernándezSanchez et al. 2011). Changes in lifestyle and diet have resulted in an increased number of overweight and obese subjects in developed (Rennie and Jebb 2005, Ogden et al. 2006) and in developing countries (Wang et al. 2002). This trend has been verifi ed in practically all ages, genders and ethnicities (Wang et al. 2002, Ogden et al. 2006). Therefore, overweight and obesity have emerged as one of the largest public health problem worldwide.
