Finding yourself confused by the seemingly endless promotion of weight-loss strategies and diet programs? Within this series, we take a look at some popular dietsand review the research behind them. The facts? The keto diet information is a low-carbohydrate, fat-rich diet plan which has been used for centuries to treat specific health conditions. Within the 1800s, the ketogenic diet was frequently used to help control diabetes. In 1920 it was introduced as an effective solution for epilepsy in youngsters in whom medication was ineffective. The ketogenic diet has been tested and found in closely monitored settings for cancer, diabetes, polycystic ovary syndrome, and Alzheimers disease.
However, this diet is gaining considerable attention as being a potential weight-loss strategy due to the low-carb diet craze, which began in the 1970s using the Atkins diet (an extremely low-carbohydrate, high-protein diet, which was an industrial success and popularized low-carb diets to a different level). Today, other low-carb diets such as the Paleo, South Beach, and Dukan diets are common loaded with protein but moderate in fat. In contrast, the ketogenic eating habits are distinctive because of its exceptionally high-fat content, typically 70% to 80%, though with merely a moderate consumption of protein.
The premise from the ketogenic diet to lose weight is that if you deprive your body of glucosethe main source of energy for many cells within the body, which is obtained when you eat carbohydrate foodsan alternative fuel called ketones is created from stored fat (thus, the term keto-genic). The brain demands by far the most glucose in a steady supply, about 120 grams daily, as it cannot store glucose. During fasting, or when very little carbohydrate is eaten, the body first pulls stored glucose through the liver and temporarily fails muscle to discharge glucose. If the continues for 3-4 days and stored glucose is fully depleted, blood levels of a hormone called insulin decrease, and the entire body begins to use fat as the primary fuel. The liver produces ketone bodies from fat, which may be utilized in the lack of glucose. 
When ketone bodies accumulate within the blood, this is called ketosis. Healthy individuals naturally experience mild ketosis during periods of fasting (e.g., sleeping overnight) and extremely strenuous exercise. Proponents from the keto benefits suggest that when the weight loss program is carefully followed, blood amounts of ketones should never reach a harmful level (known as ketoacidosis) as the brain uses ketones for fuel, and healthy individuals will typically produce enough insulin to stop excessive ketones from forming.  How soon ketosis happens and the number of ketone bodies that accumulate inside the blood is variable from person to person and depends upon factors including excess fat percentage and resting rate of metabolism. 
What exactly is ketoacidosis? Excessive ketone bodies can produce a dangerously toxic degree of acid in the blood, called ketoacidosis. During ketoacidosis, the kidneys start to excrete ketone bodies along with body water in the urine, causing some fluid-related weight-loss. Ketoacidosis usually takes place in people with type 1 diabetes as they do not produce insulin, a uwrqor that prevents the overproduction of ketones. However in a few rare cases, ketoacidosis has become reported to occur in nondiabetic individuals after a prolonged very low carbohydrate diet. [4,5]
There is certainly not one standard ketogenic diet using a specific ratio of macronutrients (carbohydrates, protein, fat). The ketogenic diet typically reduces total carbohydrate intake to less than 50 grams a dayless compared to the amount found in a medium plain bageland can be as low as 20 grams a day. Generally, popular ketogenic resources suggest around 70-80% fat from total daily calories, 5-10% carbohydrate, and 10-20% protein. To get a 2000-calorie diet, this means about 165 grams fat, 40 grams carbohydrate, and 75 grams protein. The protein amount on the ketogenic weight loss program is kept moderate in comparison with other low-carb high-protein diets, because consuming too much protein can prevent ketosis. The amino acids in protein could be transformed into glucose, so ketogenic diet fat loss specifies enough protein to preserve lean body weight including muscle, but that can still cause ketosis.
Many versions of ketogenic diets exist, but all ban carb-rich foods. Many of these foods could be obvious: starches from both refined and whole grains like breads, cereals, pasta, rice, and cookies; potatoes, corn, and other starchy vegetables; and fruit juices. Some that may not be so obvious are beans, legumes, and many fruits. Most ketogenic plans allow foods rich in unhealthy fat, like fatty cuts of meat, processed meats, lard, and butter, in addition to types of unsaturated fats, including nuts, seeds, avocados, plant oils, and oily fish. Based on your way to obtain information, ketogenic food lists can vary greatly and also conflict.
