Ketosis is a metabolic state that occurs when the body doesn't have enough carbohydrates to use for energy. In this state, the body begins to break down fat into ketones, which serve as an alternative fuel source. This process typically happens when carbohydrate intake is significantly reduced, such as during a ketogenic diet or prolonged fasting.
Understanding ketosis is important for health because it can influence weight management and energy levels. Some people seek to enter ketosis to help with weight loss or to improve mental clarity. While ketosis can be a normal physiological response, it is also a key focus in certain dietary practices, particularly low-carb diets.
In the body, ketosis helps provide energy when glucose is scarce. When carbohydrate intake is low, insulin levels drop, allowing fat stores to be broken down into ketones. These ketones are then used by various cells in the body, including brain cells, as a source of energy. This shift in fuel usage can lead to changes in metabolism and energy balance.
It is essential to approach ketosis with awareness, as it may not be suitable for everyone. Monitoring how the body responds to this state can be important for individual health and well-being.
