First, Dr. Ken Berry has not had his medical license revoked.

Second, Dr. Shawn Baker got involved in a dispute with a hospital system because he began curing people through the carnivore diet rather than through extremely expensive surgery (he is an orthopedic surgeon). This led to the hospital system losing a lot of money. They insisted that he stop curing people, but Dr. Baker refused. They retaliated against him by getting a fraudulent fellow to badmouth his work and get his license revoked. He then went to court and won and his name was cleared completely.

As for your claim that there is no evidence to back up the fact that humans were healthier before 12,000 years ago, what about the fact that they were taller and had fewer dental caries and larger brains? Also, my point was not that humans were healthier then (although they were) but that the carnivore diet was the diet that human beings literally evolved on.
