ketosis
Ketosis is a metabolic state in which the body starts using stored fat as the primary source of fuel instead of carbohydrates. This typically occurs when carbohydrate intake is restricted, such as during fasting or when following a low-carbohydrate diet. Ketosis is characterized by the production of ketone bodies, which are molecules produced in the liver from fat breakdown. These ketone bodies, such as beta-hydroxybutyrate and acetoacetate, can then be used by the brain and other tissues as an alternative energy source. Ketosis is often associated with weight loss, improved insulin sensitivity, and increased mental clarity. However, it is important to note that prolonged ketosis or very low carbohydrate intake may have potential side effects and should be done under proper supervision.
