While we can pretty much agree on what is unhealthy and healthy, the degree to which something is unhealthy is somewhat subjective. Technically wouldn’t a granade be the most ‘unhealthy” thing that you could eat? ;)
Back on subject, something that sticks out in my mind are the Hungry Man Packaged meals. There’s a rather entertaining article about them written-up here:

1,030 calories, 64 grams of fat, 2,090 milligrams of salt.
Hungryman also introduced a Hungryman XXL dish, with 1.5 pounds of food instead of the usual 1. I can’t find the nutritional facts, but I’m sure they’re even more frightening.
My heart hurts now.
