it's pretty much an alternative term for "psychologically addictive" which is basically a synonym for "enjoyable". You do something, you enjoy it so you do it more.
Read the linked material before dismissing next time.
These addictions correspond to physical and chemical changes in the brain. Believe as you will, but the degree of addiction can be measured empirically. The relevant studies are cited.
And yes, obesity is a serious problem for people who can't control their eating compulsions: they are literally addicted to food. That's why studying these things is interesting; while we need food and sex for survival (as individuals or as a species), what happens when the natural urges become obsessions?
To try an analogy, is watching a porno more akin to pigging out on cake, or more like taking an opiate? Perhaps it depends on who you are, but the evidence suggests it's a lot like soaking your brain in some seriously powerful drugs. While one enjoys a movie with it's fast pace, witty dialogue, and mind-blowing explosions, the "enjoyment" of porn is vastly different. In the latter case, it's the release of hormones and chemical transmitters that accounts for the experience. Take that away and all you have is a lame story with shallow characters. If there was even a story to begin with. If not for the drugs, why would anyone put up with that?
