Overweight and obesity are the result of excessive fat accumulation
which leads to impaired health. Nearly two billion
adults worldwide are overweight, and of these, more than half
a billion are obese [1]. The global prevalence of overweight in
the year 2014 was around 39% among adults aged 18 years or
older, being 39% for men and 40% for women. About 13%
were obese (BMI ≥ 30 kg/m2
), of which 11% were men and
15% were women [1, 2].
