The actual fasting part of this diet is when the fasting is done, when only certain foods are allowed and which lasts for a specific length of time.

The length of time that the fast lasts, depends on what the fasting is used to accomplish:

• Energy fast – can be done just for 1 day
• Detox fast – can be done over the weekend – 2 days
• Rejuvenation fast – can be done for 3 days (long weekend)
• Deep cleanse fast – can be done for 7 days*

* Any fasts that go longer than 3 days should only be done under medical supervision, as they could be dangerous for some people with certain medical conditions
