I've got a player playing as a White court Vampire, and with the template they have a feeding dependency. Let's assume that he ends up going for a while and not feeding and his stress track goes over the limit, what happens then? For this particular instance he feeds on fear.
The hunger stress track is a bit different from other stress tracks. Other stress tracks overflow as a result of an enemies' actions. The hunger stress track is only checked in general as the result of a feeding failure (see
Only if you have no powers left to lose are you taken out by a feeding failure. In that case, your failure is dictated by the game master, not an opponent. The only case when your opponent would get a chance to dictate your fate would be when the feeding failure was brought on as the result of a compel.
NOTE: If an opponent does compel a check for feeding failure and you succeed, you immediately clear out your hunger stress track, just as if it was a check between scenes.

From a separate e-mail thread asking this same thing, I got this further response:
So the progression from this interpretation is
(Posting this as asked by Fred)
There is a simple definition of being taken out (ie. running past a stress track) on all FATE 3.0 games. The player loses control of the character, and the character's fate is in the hands of any opponent(s) (YS 203). The character may or may not be able to return to the game depending on whatever the said opponent decrees within reasonable bounds.
With a White Court vampire, being taken out on the hunger track probably translates to something like passing out, freaking out, going into a feeding frenzy or doing something stupid, even maybe something suicidally stupid. You have lost control and your fate is in the hands of others.
Being taken out is a serious thing, treat it as instant death because it may well become one if your opponent offers a reasonable story for that. Remember that you can always offer a concession (YS 206).
