The Astral Diet, created by AstralLunar, is an eating and exercise program to help you slowly get a body like Astral's.
It has been performed by both Astral and his "girlfriend" Amanda. However, it has destroyed their vocal chords, allowing them to only speak in nehenhenehs.
The Astral diet is a rip-off of "The Jitka Life", based on the hilarious and somehow boring at the same time life of Twitter user Jitka.
(Warning: The Astral Diet is not FDA certified and in many cases, my cause cancer)
