ok, let's take it to the nth degree of loading and minimalism.

I wonder what a Bear Vault full of Tang would weigh?

those approx 2000 Cal/lb and its Vitamin C would take you a long way, that and a few mineral and other vitamin supplements, and burning your own fat & protein.

I could do the math, but.. a default breakfast for me on the trail is a liter of water + 3 Fig Newtons while packing up, then a liter of strong Tang to sip on the trail.
