Experts are warning about a dangerous new diet trend called, the Carnivore Diet.
It's exactly what it sounds like, an all-meat diet.
No greens, fruits, grains or pretty much anything else.
It's a growing trend after following keto or paleo diets.
Nutritionists said it's concerning, because you miss out on a lot of nutrients by only eating meat.
They warn it could have long-term health effects.
