Obesity Triggers COVID-19: Causal Discovery and Multiobjective Linear Programming Approach

Is there a causal relationship between obesity and the COVID-19 death rate? Can a nutritious diet effectively control the obesity rate? What role does GDP play in the above relationship? In this article, we analyzed the relationship between the country's energy intake structure and obesity rates, and a high proportion of meat features intake will lead to an increase in obesity rates. We estimated the direct causal effect and concluded that obesity causes the probability of death of COVID-19 patients is about three times that of the normal population. Finally, we optimize the nutritional diet for college students through multiobjective linear programming, aiming to provide a reference for effectively controlling the obesity rate and COVID-19.
