"Many people would be surprised to hear that human beings can live exclusively on animal foods. In my clinic I have patients who live entirely on animal food with great results, both children and adults. Patients with ulcerative colitis, Crohn's disease and severe mental illness do very well on a No-Plant GAPS Diet: not a leaf, not a speck of anything from the plant kingdom is consumed. These people live on meats, including organ meats, animal fats, meat stock and bone broth, fish (including shell fish and molluscs), fish stock, fresh eggs and fermented raw diary - kefir, sour cream, ghee, butter, cheese and yoghurt. In some severe cases of ulcerative colitis and Crohn's disease this is the only diet that allows them to be well, to stop all medication, to reach their normal body weight, to remove all digestive symptoms and to function to their full capacity. In severe cases of bipolar disorder, schizophrenia and other psychiatric conditions this diet can be a saviour. Some of these people have lived on this diet for 2 years or longer and have no desire to change their eating habits, because this diet works for them. Some of them tried to add a little vegetable or fruit to their regimen and found that their symptoms started returning, so they had to stop. So, based on my clinical experience I have no doubt that human beings can live very healthily without plant foods at all.
Living entirely on animal foods is not new on our planet. One of the healthiest group of traditional (so-called primitive) people in the world Weston A. Price has found in his research were Masai people in Africa who ate no plant matter at all. They are nomadic people travelling with their cattle and everything they eat is provided by their animals. They eat meat, organ meats, milk and sour milk and they drink the blood of their bulls. When they were asked why they don't eat fruit found in their habitat, they laughed and answered that fruit was food for their cows. These people had no diseases of our modern 'civilised' world whatsoever: no heart disease, no cancer, no degenerative conditions, their childbirth was easy and healthy, their bodies were trim and muscular, their life span was long and they had beautiful healthy teeth. Apart from perfect physical health these people were intelligent, joyful, peaceful, friendly and happy, no psychological problems at all. But when some of them moved to a city and adopted a modern diet, they started getting the same diseases people suffer from in any modern country.
