believable. Many 175 pound dudes put down 3500-4500 a day.
Watt is 288 pounds, probably over 300 in the offseason. He lives on healthy fats, lots of calories there.
Bacon adds up fast.
Exercising 2+ hours a day, world class genes... yeah, I can see 6000 and him losing weight, with 9000 being the cheat day.
