⚪ The loaf does not symbolize the fleshly body of Jesus
«[...] he said: 'Take, eat. This means my body.' (Matt. 26:26; John 13:21-30, NW) To which body was Jesus referring here ? To his fleshy body? Hardly, for concerning it we read that not a bone was broken, whereas Jesus broke the loaf. (John 19:36). Rather, he was referring to his spiritual body, the Christian congregation, which in the Scriptures is termed a body or Christ's body more than forty-five times. [...] Clearly the loaf pictures not Jesus' fleshly body but his body members, the Christian congregation. - 1 Cor. 10:16, 17, NW.»

⚫ The loaf symbolizes the fleshly body of Jesus
The bread loaf is symbolic of Jesus' own fleshly body, head and all, which Jehovah gave him to offer as a perfect sacrifice.
Matt. 26:26 "Take, eat. This means my body."
