I'm glad I relayed your question to cathijosephine, her response was enlightening: "Most people can't eat so many Hershey's kisses at once."

The experience I posted about did actually turn out to be sufficiently motivational to start diversifying my diet.

I now have canned chicken and instant brown rich, which I am planning to base my diet around. I do not yet have the motivation for frozen vegetables. Hmm, maybe canned.
