Why do supplies consume at 50?

I have been wondering; why have a hunger bar which goes to 100 but consumes supplies at 50? Fully half the bar is, so far as I can tell, not used for any reason whatsover. Why not just make use of the entire bar and have food consumed at 100? Or make 50 the end of the bar?

I’m having Spinal Tap flashbacks here. Our hunger bar goes to 100!

It’s used once supplies run out. The higher, the worse the events that come up.

Ohhhhh.

Thanks, that makes sense.

Basically, like in real life, you get hungry a long time before you starve to death.
