A fad for consuming high-protein, high-fat food, while avoiding vegetables, has taken off online. Followers are doing themselves no favours

O

nce, it seemed that much of the world was intent on drastically cutting back on meat for health and environmental reasons. Vegetarian and vegan options appeared on restaurant menus and the very idea of a bloody red steak became almost unthinkable in liberal circles. And yet the carnivore diet is now all over Instagram and TikTok, prompting health bodies to start issuing warnings.

Followers of this diet eat meat, fat, seafood, eggs and butter, avoiding all vegetables, fruits, grains and legumes as if plants were, as Paul Saladino, an advocate of this diet alleged, “poison”. Dr Saladino is a US psychiatrist and health influencer with a range of supplements called Heart and Soil that contain dried animal organ meat. He appears shirtless on social media, denouncing vegetables, which he says will harm us. Other Instagrammers tuck into plates of huge steaks and seven or more eggs for breakfast. It’s not just for weight loss.

Joe Rogan has claimed on TikTok that his brain was working better after a week of meat, fat, bacon and eggs, and nothing else. Others show off huge muscles or say their skin has improved. There’s something messianic in their insistence that going carnivore has changed their life.
