Christopher Altomare, of New York, has launched a class action legal case against Johnson and his companies Ancestral Supplements, LLC and The Fittest Ever, and LLC.
The lawsuit, which has been seen by the
New York Post, reads: "Liver King persuaded millions of consumers to adhere to, or abide by, the Eat Tenet by repeatedly making representations to consumers that his near-perfect physique, and optimal health, were solely attributable to his adoption of the Ancestral Tenets, predominantly the Eat Tenet."
It's claimed that the bodybuilder encouraged a "dangerous and life-threatening diet", causing "severe" food-borne illnesses.
Johnson and his companies have long promoted their Nine Ancestral Tenets lifestyle, which encourages people to consume raw animal parts, such as the pancreas, the heart and kidneys.
The suit says this diet was unsustainable for consumers, therefore forcing them to buy Johnson's supplements.
