There is no real challenge. Awhile back, there was a thread on the Diet forum about the most ridiculous amounts of food people had ever put down in a sitting, and I said that I'd once scarfed a pound and a half of steamed broccoli in the space of about an hour. The point was to keep from eating other, less healthy things, like the carbs that some people are addicted to.
ANYTHING smothered in cheese counts.
