The werewolf diet, also known as the lunar diet and the moon diet, is a fad diet that centers upon users fasting according to the lunar phases.[1] This has prompted people to nickname the diet plan the "werewolf diet" as a result.[2] Celebrities that have endorsed the diet include Demi Moore and Madonna.[3]
The diet is typically performed in one of two fashions: the "basic moon plan" or the "extended version".[4] The first plan is a variation of the juice cleanse in that individuals are only permitted to drink water and freshly squeezed fruit or vegetable juice.[4] This is typically performed in a 24-hour period during either the full or new moon.[4] The extended version requires the diet to begin with the initial fast during the full moon and then follow a series of eating plans tailored to the various moon phases, such as not eating after 6 p.m. or eating less than normal.[5]
