The modified SEIR (susceptible-exposed-infected-removed) model to predict COVID-19 infection and outcome. S: susceptible, E1: patients who consume the macronutrient above the cut-off, E2: patients who consume the macronutrient below the cut-off, I1: COVID-19-positive patients, I2: COVID-19-negative patients, H: hospitalized, OU: outpatient, α: Rate of transmission from S to E1, 1−α: Rate of transmission from S to E2, m: rate of death in susceptible individuals,\({\gamma }_{1}\):Rate of transmission from E1 to I1,\({\gamma }_{2}:\) Rate of transmission from E1 to I2, \({\gamma }_{3}\):Rate of transmission from E2 to I1, \({\gamma }_{4}:\) Rate of transmission from E2 to I2\(, {\beta }_{1}:\) Rate of transmission from I1 to H, \({\beta }_{2}\): Rate of transmission from I1 to OU, \({\beta }_{3}\): Rate of transmission from I2 to OU
