The answer to this question is yes, a 16 hour fast can put you into ketosis. Ketosis is a metabolic state in which your body uses fat instead of carbohydrates for energy. When you fast for 16 hours, your body is forced to use stored fat as fuel, which can lead to ketosis.
However, it is important to note that the amount of time it takes to reach ketosis varies from person to person, and can depend on a variety of factors such as age, activity level, and diet. Additionally, it is important to remember that the ketogenic diet is not for everyone, so it is important to consult with your doctor before beginning any fasting regimen.Â
