That's not good BB,
I know what I get like when I'm hungry, my blood sugar levels drop and I get into a really bad mood but at least I know I can eat any time I want to. They don't even have the luxury of knowing they can eat soon.
I feel sorry for them.
It reminds me of BB1 when they all lost loads of weight [though that time the house and the tasks were designed to build a team and not to make them competitive so they didn't fight].
