You want this to be your only source of nourishment? I think perhaps
you might want to consult a nutritionist. You will will be deficient
in protein and probably other essential parts of a balanced diet.

Deficient is not the right word.
Just about anything necessary is absent, except (likely) water.
I would not want to guarantee that it does contain enough water.
It is either meant as a method of fasting or as a magic / religious method
to derive nutrition from another dimension.
