Read the Bible - great advice! Since you do read the Bible and believe what you read ( as we all should ) that means when Jesus said “This is My Body”, you believe he meant it’s His Body, correct? I am sure you will say correct, unlike a lot of people who claim to read and believe the Bible, but really don’t!
I suspect that a logical fallacy is right around the corner; namely, Jesus already HAD a body when He said this.
Are we supposed to 'believe' that the loaf(?) of bread He was holding was part of His body, too?
