For years, I chalked up my constant hunger and love for red meat to a fast metabolism—maybe even an overactive imagination. My mom, on the other hand, had a more… creative theory: a lintworm was living inside me, stealing all my nutrients. (Spoiler: no lintworm.)
What I did discover was far more interesting. My blood type—O negative—holds real clues about why my body thrives on animal protein. But how do you know if your cravings are trying to tell you something too?
