A review of ketogenic diets and their potential impact on COVID-19: Is there an interaction?

Abstract

The aim of this review is to explore the potential significance of ketogenic diets (KDs) in the treatment and prevention of coronavirus, specifically focusing on their beneficial impacts on inflammation, immune responses, and the respiratory system. The study reviewed several COVID-19 observations and findings, particularly those concerning obesity as a contributing factor. As per the study, notable obesity is linked to an elevated chance of intensive care unit (ICU) admission requiring invasive mechanical ventilation in individuals with COVID-19. Additionally, the increasing weight gain associated with a SARS-CoV-2 infection prognosis may be attributed to various factors, including prolonged systemic inflammation, susceptibility to acute respiratory infections, and the influence of the viral disease. The article ultimately concludes that ketogenic diets may play a pivotal role in managing and preventing SARS-CoV-2 by diminishing the virus's impact on inflammatory responses, immune functionality, and respiratory system health. Furthermore, the article focuses on the link between extreme obesity and severe COVID-19 results, implying the need for weight control in high-risk patients.
