I think your analogy of Jesus becoming flesh and bread becoming flesh becoming Jesus breaks down do the fact when Jesus was here on earth He was who He said He was, the Son of God. When He was conceived He was God. When He was born He was God. When He lived here He was God. When He died in the flesh and was resurrected in the glorified flesh He was God. There was no mystical change in His person nor was there one when the Lord's Supper was instituted. For the elements to be changed into His actual flesh and blood would have been a gross violation of the Mosaic law that even Paul and the Jerusalem Council did not countermand in the letter to the Galatian churches.
And when He gave the Bread of Life discourse and when He instituted the Eucarist, He was doing what He said He was doing. The analogy only breaks down if you lack faith that He meant what He said.

Sunds ghastly, doesn't it? That's why so many left Him after the John 6 discourse. He did not correct them in takng Him at face value.
