There's this recent (2021) study published on Current Development in Nutrition, which concludes "Contrary to common expectations, adults consuming a carnivore diet experienced few adverse effects and instead reported health benefits and high satisfaction. Cardiovascular disease risk factors were variably affected. The generalizability of these findings and the long-term effects of this dietary pattern require further study."

And a Letter to the Editor (2022) of that same journal commenting the limitations of the previous article.

Further research is needed, as it's often the case on the edges of the scientific advancement. We'll be tuned... 😊
