Ketone are waste products in the body that are a result of fat burning.
In the fitness context, ketones refer to chemicals produced by the liver from stored fat when the body doesn't have enough glucose for energy. This process is called ketosis and is often associated with low-carbohydrate diets like the ketogenic diet.
Ketones can be measured in the blood, urine, or breath, and can indicate that the body is in a state of ketosis. In the fitness context, ketones are often used as a marker of weight loss and body fat reduction. Some athletes and fitness enthusiasts also use exogenous ketone supplements to enhance their physical performance or to promote fat burning during workouts.
Examples of foods that are high in healthy fats and can promote ketosis include avocados, nuts and seeds, fatty fish, coconut oil, and olive oil. However, it's important to note that the ketogenic diet is not appropriate for everyone, and individuals with certain medical conditions should consult with a healthcare professional before making significant changes to their diet.
