How long did it take to you, or people you heard about, to start liking the taste of salt free food?

With enough will, anyone can just go cold turkey I suppose, but what is the average length of time that it takes for the average person to just eliminate adding salt when cooking, and so on?
I am asking because The Salt Institute is trying to convince the public that vegetables are “not palatable without salt”, blah blah blah, in order to get people not to reduce their salt intake.
