Y'know, it's amazing how some of the foods I wouldn't normally consider particularly palatable somehow turn into ambrosia when I haven't eaten anything substantial in a few days. Spam turns into such a food on about day 2. Ants become yummy on day 4. Armadillo needed slightly more than 10 days of starvation, and grubs (more than one anyways) will take me about 8 days I reckon. Beyond two weeks I figure I would eat my own guts.
