Carb-nite is foolish is you ask me. This just seems like a way to justify eating junk. Even if we argue that re-feeds are needed (they're not) then you should refeed with whole foods not junk. If people choose to eat junk one night every week, that's there choice. But one shouldn't fool themselves into thinking its 'healthy.' As for the argument about increasing thyroid hormones then this is a weak argument. Why? After the re-feed the hormones will return back to how they were anyway. Possibly hormones will remain more stable if you don't refeed. Sounds like pseudo-science to me. Not buying it...
