On the John Hopkins ketogenic diet, a person can eat foods that are high in fat but that are low in carbohydrates, notes John Hopkins Medicine. The diet requires strict adherence to these type of foods and also requires modification by an experienced doctor.
The foods on the diet are chosen by a doctor and are determined based on each individual patient, states John Hopkins Medicine. The diet should not be attempted on ones own as there are side effects associated with the diet. Side effects for those who are on the ketogenic diet include constipation, vomiting, cholesterol spikes and kidney stones. However, these symptoms are all manageable and often avoidable with the careful monitoring of an experienced doctor, notes the Hopkin's Children Center. A brief hospital stay at the beginning of the diet is also recommended.
Most of the time, the ketogenic diet is used on children to help control problems such as epilepsy and seizures. It was first created in 1921 and works by "triggering biochemical changes" that work to reduce or completely eradicate the short circuits in the brain that can cause seizures. For adults, John Hopkins offers a modified Atkins diet that can work to lower seizure rates as well. The diet is often recommended for patients with GLUT-1 deficiency as well as pyruvate dehydrogenase deficiency because of its low risks. In the past, some doctors have been worried about the diet because they felt that children would be subject to "dangerous biochemical changes," however, this is not true, as noted by John Hopkin's Children Center research.
