Impact of obesity on COVID-19 and its dietary prevention and control measures

ABSTRACT

Since the global pandemic of COVID-19, a huge challenge has been brought to human health and life. Here, we review the literature and present a comprehensive analysis to identify the relationship between obesity and CDVID-19. Obesity can cause chronic inflammation, respiratory impairment, vitamin D and other micronutrient deficiencies, and dysbiosis in humans, thereby affecting susceptibility and disease severity of COVID-19, as well as the body's response to the vaccine. The COVID-19 outbreak causes psychological stress, sleep disturbance, increased sedentary behavior, and increased intake of fast foods and overprocessed foods, which will increase the risk of developing obesity. Over 50% of the world's population is currently overweight or obese, and the number of COVID-l9 cases has rapidly increased to over 470 million. According to the theory of public health prevention and control, we propose that a comprehensive program with rational dietary action as the core is the optimal strategy for and controlling preventing and controlling obesity and COVID-19.
