It's social media's latest beef – can you survive on the carnivore diet and, more importantly, should you? "Meatfluencers" on TikTok are extolling the virtues of a regime in which they eat only animal products, including some dairy, while excluding fruit, vegetables, nuts and grains, and true adherents drink nothing but water.
Is there really a health benefit? The carnivore diet is an extreme form of the ketogenic (keto) diet, which by limiting carbs, forces the body to burn body fat for energy instead. Proponents focus on a 2021 online study that found that "contrary to expectations", eating only meat had several health benefits, "especially in participants with diabetes", Dr Bhavini Shah told Glamour. But experts have "voiced concern regarding the reliability of the research", which was based on self-reported, unverified responses.
Despite such scepticism, a growing number of men and women are joining the "meatfluencing" trend, which was long a male-dominated space.
What do doctors say? Doctors and dieticians say the carnivore diet lacks essential nutrients and could be a form of disordered eating.
People report benefits for three reasons, PhD researcher Patrick Elliott told the Irish Independent. First, there are few counterarguments from people who have had a bad time on the diet. There is also a strong "anti-establishment narrative" against following recommended guidelines. Finally, the person's diet may not have been good before they changed to meat-only so they may feel better, "particularly if they have gastrointestinal issues like IBS or IBD and they are reducing trigger foods, or if someone has given up junk food".
But health risks associated with a meat-heavy diet include developing heart disease, hypertension, type 2 diabetes and some cancers. In addition, there may be unpleasant daily side-effects of cutting down on fibre, including constipation, headaches and bad breath.
What should we be eating? If you want to embrace a healthy diet, said the Daily Mail, "mountains of research" points to one answer: a plant-based regime "rich in fruits, vegetables, whole grains and legumes". |
