Aaron Hartman, MD (YouTube video, Aug 17, 2020) discusses two modifiable risk factors for severe COVID-19: obesity and alcohol consumption. He cites UK data showing increased alcohol sales (~14% since lockdown) and that ~10% of calories in the UK come from alcohol; notes US obesity prevalence (~40% overall; ~50% in African Americans; ~33% of children); explains biological mechanisms (alcohol depleting glutathione, obesity as an inflammatory driver) and cites a French study reporting increased ICU/ventilation risks for higher BMI (BMI 30–34: 1.8x critical care admission and 3.6x complications; BMI >35: ~7x risk of mechanical ventilation). He also points viewers to dietary resources (elimination diet, paleo/renewed food plan, detox plan) and general lifestyle guidance to reduce inflammation and weight.
