Imagine doing your entire food shop at a butcher's. No vegetables, no bread, no fruit, no pasta, milk or biscuits – just a trolley full of meat, fish, eggs and lard.
That’s the carnivore diet. Its gospel has been preached all over the internet – by fitness influencer Brian Johnson (aka Liver King), Canadian psychologist Jordan Peterson and podcaster Joe Rogan (who said the diet gave him “sporadic bouts of hellacious projectile doodoo”).
But despite such vivid imagery, the carnivore cult is growing.
Data from Google Trends shows that searches for the term “carnivore diet” roughly tripled in the UK and US from 2022 to 2025, and there are now more than 160 carnivore cookbooks listed for sale on Amazon.
There’s no real science proving the diet is beneficial, but many meat munchers feel confident in their choice because they think our hunter-gatherer ancestors ate mainly (or only) animals.
