This is an excellent question. I never thought about it before; so I looked it up. This is what I found
A narrowing of the meaning "suddenly or without preparation," from cold turkey being a dish that requires little preparation; originally used for heroin addicts.
From the American phrase talk turkey meaning "to speak bluntly with little preparation".
