Brian Johnson, known by his online alias Liver King, is an American fitness social media influencer and businessman.
[2][3] He is known for promoting what he calls an "ancestral lifestyle", which includes eating large amounts of raw unprocessed organs and meat focusing on a daily intake of liver.
[9] Johnson claims that he was active in sports growing up, particularly BMX, but was undersized for his age, and had a bad speech impediment that required extensive vocal therapy.
[10] He later relocated to Houston to pursue a job as a pharmaceutical rep.[11] Johnson studied biochemistry and attended medical school, before dropping out to become a pharmacist.
[13] Johnson's dietary recommendation of eating raw meat has been criticized as dangerous, due to the associated risk of bacterial infection from its consumption.
