Although not recommended within the Keto Diet itself, intermittent fasting can also help you to reach a state of ketosis. The longer you fast the more ketones your body produces but we always suggest that you start working your way up to 16 hours by incrementing fasting intervals starting from 6-8 hours and work your way up. Fasting for a full day can also help but we understand that this can be very hard for many people. During this time you will limit your intake to liquids, such as smoothies, juice or soups. Again water is vital as you would need to flush out any toxins released by the body during this time. Detoxification is, in fact, obtained through fasting, as well as via other means.>
