For Asian and Pacific Island populations, the points of BMI would be cut off to overweight in 23.0 kg/m2 and obesity in 25.0 kg/m2 (Caveney et al., 2011). On 12 May in 2016, the Lancet published a report about trends in adult body-mass index in 200 countries from 1975 to 2014. This report showed over 39 years the BMI in both men and women have been increased approximately 2.4kg/m2. In other words, the global population becomes 6kg heavier on average in 2015 than 1975. Over the past 39 years, obese people have gradually exceeded the underweight people (BMI30kg/m2 or more or BMI>27kg/m2 with at least one obesity-related disease (diabetes, hypertension, obstructive sleep apnea, etc) (Caveney et al., 2011). Oude (2009) demonstrated that drug treatment has better efficacy than lifestyle treatment after six-month study. In addition, Orlistat, which used in pharmaceutical obesity prevention to prevent fat absorbed in the gastrointestinal tract, could lead to reducing weight between 4kg or 10kg over one year in randomized clinical trials (Douglas et al., 2015). Nowadays, orlistat is the only drug with the license available in China and Europe, and it approved by both government agency for sale without the prescription.
