Insulin is one of the hormones the pancreas secretes in the presence of carbohydrates.Insulin's purpose is to keep blood glucose levels in check by acting like a driver, pushing the glucose into cells.
When the body is in a ketogenic state, this means that lipid energy metabolism is intact.Glucagon is also secreted by the pancreas when glucose levels fall too low.This usually happens when a person skips meals, or does not consume adequate amounts of carbohydrates for an extended period of time.The main benefit of ketosis is that it increases the body's ability to utilize fats for fuel, which gets very lazy on a high-carbohydrate diet.When on high-carbohydrate diets, the body can usually expect an energy source to keep entering the body.Insulin has a lipolysis-blocking effect, which can inhibit the use of fatty acids as energy.
Also, when insulin is brought to low levels, beneficial hormones are released in the body, such as growth hormone and other powerful growth factors.
Ketones can be used by all tissue containing mitochondria, which includes muscle and the brain.
I feel the benefits of the ketogenic diet outweigh the pitfalls, but as with any diet, speak with your doctor first.
Some fatty acids are oxidized by the liver for energy production.
Others can be partially oxidized to form the substrate acetoacetate, which is then converted to beta-hydroxybutyric acid; collectively, these are termed ketone bodies.
But in the state of ketosis, the body has to become efficient at mobilizing fats as energy.
