Obesity is a global problem. The results from population-based studies pooled across countries show an increase in the mean Body Mass Index (BMI) and prevalence of obesity between 1975 and 2014, with a higher increase in women (21.7kg/m2 to 24.2kg/m2 for men and 22.1kg/m2 to 24.4kg/m2 for women). Within the same period, there was also a corresponding increase in life expectancy (59 to 71 years). In the general sense, the increase in BMI and prevalence of obesity should correspond to a decrease in life expectancy. However, the global data shows the reverse, thereby creating the paradox that the world is getting fatter and healthier. The global increase in BMI and obesity varies drastically across countries; more so, the variance is large among several demographic subgroups. For example, low and middle-income countries have higher prevalence of individuals with low BMIs, which has been associated with economic inequalities. The determination of optimum BMI level in studies that associate BMI with mortality is a controversial issue. Some studies have associated high BMI with reduced mortality. However, these studies use only BMI, which does not account for confounding effects. Whereas, the use of BMI markers considers optimum levels to be low-normal. Pharmacological interventions are being implemented globally as result of adverse metabolic and physiological effects associated with elevated BMI levels. However, these do not address some of the health effects and economic
