Paleo diet may be bad for heart health

I have heard a lot of diets such as this, Paleo diet, keto diet, South Beach diet, and a lot more. Some of them are not anymore heard of. Why? Aren't they effective? The thing is such diets are just overrated. Look at this Paleo diet. They said it is good for the body, but this health issue might arise.
