When you think of fasting it likely draws up images of completely denying your body food. While fasting was once thought as a way to sacrifice or pay penance for many religions it has developed into a way of cleansing your system or giving your body a much needed reboot. Many fasts today are designed as "liquid fasts" and these fasts can include yogurt as a source of nutrition.
Research the benefits of starting with a liquid fast or a cleansing diet followed by a liquid fast. If it is your first time fasting, you should probably start with a seven to fourteen day liquid fast to ease you into the process.
Purchase the liquids and yogurt you intend to eat during your fast. Cultured yogurt without sugar works for the fast. This provides your body with protein to help keep you from feeling worn down and the pro-biotics naturally occurring in the cultured dairy help clean your system.
Maintain a low caloric intake for the entirety of the fast. Consider somewhere between 500 to 750 calories per day. Closely tabulate the total calories between your juices and yogurt in order to stay within the range.
Drink lemon water with a little honey or agave if you are feeling run down or thirsty. This has very little caloric value and will help reduce your hunger.
