Obesity, a silent pandemic, is rapidly spreading across all age groups and populations worldwide. >1 billion individuals are expected to be living with obesity by 2030 [1]. Parallel to the obesity pandemic, the population of the World is getting older, and both the number and the proportion of older adults (people aged 65 years and above) are increasing. The World Health Organization (WHO) declares that the number of older adults will double by 2050, reaching 1.5 billion, which is 22 % of the total population [2].
