They are associated with higher rates of heart disease and negative metabolic effects.
Ironically, the meat consumed by our ancestors contained much less fat than current farm-raised meat. Not really. In tropical habitats, they ate a variety of plant and animal foods. In certain environments, the majority of calories may have come from protein, but the bulk of the diet was still plants. It has the potential to be healthy. The typical paleo diet, however, puts most at risk for deficiencies in calcium and vitamin D, which are critical to bone health.
At the same time, saturated fat and protein can be consumed far above recommended levels, increasing the risk of kidney and heart disease and certain cancers.
Not true for complex carbohydrates. Whole grains, fruits and vegetables are important fuels for brain and muscle activity. But most of us can and should eat fewer refined carbohydrates, which add unnecessary ingredients and calories but little fiber and protein and few vitamins and minerals to our diets.

Hidden danger : Dairy restriction can lead to deficiencies in calcium and vitamin D, which are critical to bone health. Hidden danger : Consuming the Paleo Diet-recommended amount of saturated fats can increase the risk of kidney and heart disease, as well as certain cancers. Hidden danger : Past and current research suggests that a heightened level of high fat meat and saturated fat can increase LDL bad cholesterol and the risk of bowel cancer.

Eating too much red meat can also be harmful to the kidneys, which play a role in metabolizing protein. One study found that replacing one serving of red meat with another type of protein — like chicken or seafood — can reduce the risk of end-stage kidney disease by The paleo diet has been linked to weight loss and improvements to blood pressure and lipid profiles.
