The Carnivore diet is pretty safe and a healthy diet to be on.
But for some people the Carnivore Diet can be dangerous and lead to increasing the risk of a Urinary Tract Infection in some woman and also increase some peoples risk for heart disease, especially for those people with certain genotypes.
I personally would not recommend going on a Carnivore diet alone because you need other healthy foods to keep your body healthy.
I would also speak with your doctor first before going on any potentially unhealthy diet because they can assess your situation better and let you know if the Carnivore Diet or any other diet is either healthy or unhealthy for you.
People are different and some types of diets affect people more than others.
