Nearly all weight reduction diets to varying degrees focus on either calorie reduction or the manipulation of the intake of one of the 3 essential macronutrients (proteins, fats, or carbohydrates) to achieve their weight loss effects.
Ketogenic diets are a team of “high-fat, moderate protein” or “high-protein moderate fat” but very low-carbohydrate diets. The term ketogenic basically refers to the increased production of ketone bodies occasioned through the elevated rate of lipolysis (fat break down). Ketones are the acidic by-products formed throughout the intermediate breakdown of “fat” into “fatty acids” by the liver.
The very first groups of ketogenic diets were actually developed dating back to the initial 1920s from the Johns Hopkins Pediatric Epilepsy Center and also by Dr. R.M. Wilder from the Mayo Clinic to deal with children with difficult to control seizures. The diets were designed to mimic the biochemical changes that occurred during periods of fasting, namely ketosis, acidosis, and dehydration. The diets involved the intake of about 10-15 grams of carbohydrates each day, 1 gram of protein per kilogram bodyweight in the patient and also the remaining calories based on fats.
Today, the promoters of ketogenic diets are strongly of the view that carbohydrates especially the high glycemic index ones would be the major main reasons why people gain weight. Carbohydrate foods are usually metabolized to produce glucose, a kind of simple sugar which is generally viewed as the most preferred power source for that body since it is a faster burning energy. Although the body can break up muscle glycogen (a blend of glucose and water) and fat to produce energy, it however prefers to get it from high glycemic index carbohydrates from diets.
Of the macronutrients, carbohydrates are therefore argued to become the key cause of weight gain. This is much more because the increased consumption of high glycemic index carbohydrate foods generally causes fluctuating glucose levels because of the fast absorption into the bloodstream and which more often than not leads to the overproduction of insulin. This is where the issue actually starts.
Insulin is actually a hormone that regulates blood glucose levels and thus upkeep of the power in/energy out equation from the body which rules bodyweight. Excess quantities of glucose within the bloodstream causes the unnecessary secretion of insulin which results in the storage of the excess glucose within the body as either glycogen in liver and muscle cells or fat in fat cells.
One goal of ketogenic diets is therefore to lessen insulin production to its barest minimum by drastically reducing carbohydrate consumption when using fats and proteins to supplement the body’s energy requirement.
Despite the ability of ketogenic diets to lessen insulin production, their main objective is ultimately geared towards inducing the condition of ketosis. Ketosis could be thought to be a condition or state in which the rate of formation of ketones created by the breakdown of “fat” into “fatty acids” through the liver is more than the capacity of tissues to oxidize them. Ketosis is really a secondary state of the entire process of lipolysis (fat breakdown) and it is a general complication of low-carbohydrate diets. Ketogenic diets are therefore favorably disposed to the encouragement and promotion of ketosis.
Prolonged periods of starvation can simply induce ketosis but it can also be deliberately induced by utilizing a low-calorie or low-carbohydrate diet with the ingestion of large amounts of either fats or proteins and drastically reduced carbohydrates. Therefore, high-fat and-protein diets are definitely the weight-loss diets used to deliberately induce ketosis.
Essentially, ketosis is a very efficient form of energy production which fails to involve the creation of insulin because the body rather burns its unwanted fat for energy. Consequently, the thought of reducing carbohydrate consumption fails to only reduce insulin production but also practically forces your body to burn its fat deposit for energy, thereby making using ketogenic diets an extremely powerful approach to achieve rapid weight reduction.
Ketogenic diets are made in a way they initially force your body to exhaust its glucose supply and after that finally move to burning its unwanted fat for energy. Subsequent food intakes after inducing the state ketosis are designed to keep the ketosis process running by appropriately adjusting further carbohydrate consumption to provide merely the basic level of calories needed by the body.
For instance, the Atkins Diet which is obviously the most popular ketogenic diet aims to aid dieters achieve what the diet calls the individual’s Critical Carbohydrate Level for Maintenance (CCLM) – a carbohydrate consumption level hpubkc the dieter neither gains nor loses weight anymore.
In 2003, the Johns Hopkins treatment center created a modified version of the Atkins Diet protocol to take care of a small group of 20 children with epilepsy. Right after the treatment, it was observed that two-thirds experienced a substantial decline in their seizures while 9 were able to reduce their medication dosages and none developed kidney stones.
Furthermore, there are ongoing scientific studies from the National Institute of Health (NIH) concerning the potency of the classic ketogenic diet as well as the modified versions in the Atkins Diet in helping people to lose weight and in addition in the treating of epilepsy. It is actually equally interesting to notice that this National Institute of Neurological Disorders and Stroke (NINDS) is performing studies on the effect of ketogenic diets and in addition formulating medications that can produce the same influence on weight reduction.
