However, during times of prolonged starvation or very low-carb diets, the brain shifts its main fuel source from glucose to ketone bodies, also known simply as ketones. Ketones are molecules formed from the breakdown of fatty acids. Your body creates them when carbs are not available to provide your body with the energy it needs to function. Ketosis happens when the body produces large amounts of ketones to use for energy.
This condition is not necessarily harmful and is much different from the complication of uncontrolled diabetes known as ketoacidosis. However, even though ketones are the primary fuel source for the brain during times of starvation, the brain still requires around one-third of its energy to come from glucose via muscle breakdown and other sources within the body By using ketones instead of glucose, the brain markedly reduces the amount of muscle that needs to be broken down and converted to glucose for energy.
This shift is a vital survival method that allows humans to live without food for several weeks. Summary The body has alternative ways to provide energy and preserve muscle during starvation or very low-carb diets.
