Ketogenic Diet

Updated: Nov 6, 2020


Once ketosis usually within a few days of implementing the diet, insulin levels drop, causing the pancreas to start producing glucagon. Glucagon determines the rate at which ketones are produced and sends the body into fat-burning mode, which is why the diet has gained recognition as a means for weight loss.

The Ketogenic Diet, is based on the process of ketosis, in which the body uses ketones for fuel instead of glucose. Ketones are a byproduct of fat metabolism that are utilized in times of starvation, carbohydrate restriction, or excessive exercise. For the body to reach a state of ketosis, calorie intake must be limited and comprised of 80% fat. The remaining calories should come from low-carb vegetables and protein.

The diet is customized to individual needs and is usually maintained for extended periods of time. It’s advised that the first day and night be a period of fasting, and that the diet be gradually introduced over a couple of days so that the body has time to adjust. Each meal is carefully measured, including fluids, and a daily multi-vitamin and mineral supplement are imperative.


Potential side effects include dehydration, constipation, vomiting, high cholesterol, kidney stones, behavior changes, slower growth rates in children, pancreatitis, excess fat in the blood, and vitamin and mineral deficiencies. As a result, individuals on this diet should be closely monitored by an experienced team of practitioners.


The Ketogenic Diet is primarily recommended for children with epilepsy as there have been numerous studies showing a reduction in seizure rates. It’s shown to be more successful for children than adults because parents are able to carefully supervise food intake. This approach does not work unless it is followed exactly.
