Two metabolic processes come into action when there is low carbohydrate availability in body tissues: gluconeogenesis and ketogenesis. Glycogen stores deplete, forcing the body to go through certain metabolic changes. When the body is deprived of carbohydrates due to reducing intake to less than 50g per day, insulin secretion is significantly reduced and the body enters a catabolic state. The resurgence of the ketogenic diet as a rapid weight loss formula is a relatively new concept the has shown to be quite effective, at least in the short run.īasically, carbohydrates are the primary source of energy production in body tissues. He also coined the term "ketogenic diet." For almost a decade, the ketogenic diet enjoyed a place in the medical world as a therapeutic diet for pediatric epilepsy and was widely used until its popularity ceased with the introduction of antiepileptic agents. Russel Wilder first used the ketogenic diet to treat epilepsy in 1921. Specifically, in a 2000 kcal per day diet, carbohydrates amount up to 20 to 50 g per day. The dietary macronutrients are divided into approximately 55% to 60% fat, 30% to 35% protein, and 5% to 10% carbohydrates. A ketogenic diet primarily consists of high fats, moderate proteins, and very low carbohydrates.
