I found this web site about a solution to eating disorders. It is not a diet plan but a way to allow God to heal you.

Why Manna?
Why Choose the Manna From Heaven Program over others?
“Do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God.” Romans 12:2
I wrote the Manna From Heaven Program after God healed me from an eating disorder. For years I desperately sought help for my obsession, thinking that if I just had more will power I could control my eating.
31 And the house of Israel called the name thereof Manna: and it was like coriander seed, white; and the taste of it was like wafers made with honey. (Old Testament | Exodus 16:31)
Here is a photo of coriander seed.
Here is a video about what Manna might have been. It is very likely that manna is still growing in the desert there. We still have the Sea Gulls in Salt Lake City.

nowheretorun1984—September 16, 2008 — In this 9 min video I make a case that the Manna spoken of in the Bible may be the Terfezia and Tirmania Desert Truffles of the Middle east region.
here are some factors I considered
Sustenance capability
Geography
habitat
it is said that manna was white and tasted like wafers in honey.
Numbers 11:7 adds that manna was like coriander seed, the color of bdellium,
Numbers 11:8 adds that it could be ground, pounded, boiled and made into cakes.
