Thus, the purpose of this research is to investigate the influence of dietary knowledge improvement on the level of obesity and overweight among adults. In their study, the authors used balanced panel data comprising 10,400 samples from 2011, 2009, and 2006 reviews of the China Nutrition and Health Survey. For that period, the rates of overweight have increased from 26% to 31%, and the rates of obesity have increased from 6% to 9% of the entire population (Zhou, Zeng, Jin, & Cheng, 2017). According to the results, obesity and overweight are becoming a problem in China, and dietary knowledge among adults should be improved. Moreover, according to the empirical results, the improvement in dietary knowledge among Chinese adults has no considerable impact on adult obesity and overweight, which is considered a likely result of not receiving dietary knowledge systematically and lacking guidance on the behaviors related to obesity and overweight (Zhou et al., 2017). Particularly, Chinese adults urgently need systematic dietary education, which will be incorporated into the current obligatory education system and will play a crucial role in increasing awareness about the diseases that can be caused by obesity and overweight.
