These scam diets were written to sell supplements, protein bars, and books (look it up, I’m not going to link to them here). They tell people everything they want to hear such as:
Saturated fat by itself probably is not problematic.
Butter is ok.
Saturated fat has a minimal effect on cancer or heart disease.
-Loren Cordain – advocate of the Paleolithic Diet
Scientists labeled Fat the Enemy.
Why they were wrong.
-TIME Magazine Cover June 23, 2014
Eat liberally a combination of fat and protein in the form of poultry, fish, shellfish, eggs and red meat, as well as pure, natural fat in the form of butter, mayonnaise, olive oil, safflower, sunflower and other vegetable oils (preferably expeller-pressed or cold-pressed).

Eat absolutely no fruit, bread, pasta, grains, starchy vegetables or dairy products other than cheese, cream or butter.
-Atkins.com – The Rules of Induction #4
(Fruit is healthy but cheese, cream and butter are not.)
At a minimum, take a good daily multivitamin with minerals, including potassium, magnesium and calcium, but without iron.

(You should get adequate vitamins and minerals from food on a healthy diet. But if Atkins was a healthy diet they couldn’t sell their supplements, protein bars and shakes.)
Following the Paleo diet can lead to nutritional deficiencies such as those of vitamin D and calcium, which in turn could lead to compromised bone health. There is also a risk of toxins from high fish consumption.
