¿The Zon¿ Diet has no specific phasing and is intended to be followed throughout the rest of one's life. There are two ways to follow the Z¿n¿ D¿t: the hand-eye method or using Z¿n¿ food bl¿¿k. Most people begin with the hand-eye method and progress to using Zone food blocks later since it is more advanced. You may switch between the two approaches anytime you want since they both have their own advantages.
