Eating 4k in a day is a chore if you are used to controlling your intake and eating clean. It's not hard if you eat poorly. There was once a time that I could put down a Costco box of Goldfish crackers (7400 calories) in an evening of hacking, with a few cans of Coke (another 600) to wash it down with. A package of Oreo cookies is north of 2500 calories. A "single serving" pint of Ben & Jerry's ice cream is well over 1k calories. Eating 4k calories well is hard - caloric density in good foods isn't nearly what it is in bad foods, and you're just going to physically fill up your stomach. Eating it poorly is, sadly, way too easy.
