As a practical matter, the blue whale is going to turn into a rotten carcass and decay long before a person could eat it.

Getting into "assume a spherical cow" type calculations where we ignore rot, and just base this on size and general calories, we can plug through the math and see what kind of silly answer we get.

I don't know the caloric content of a blue whale. Some googling shows that cows weigh about a thousand pounds, and one cow can make about a thousand quarter-pound burgers. With each burger coming in at roughly 300 calories, this give a typical cow about 300,000 calories. Admittedly, this ignores non-burger stuff that we eat, but since I also don't know how meaty a blue whale is, let's just run with these numbers and see what happens.

A blue whale (again according to google) weighs about 300,000 lbs, or as much as about 300 cows. Assuming a roughly similar caloric content per weight as cows, this puts our blue whale at 90,000,000 calories.

Divide that by 2500 calories per day, and you end up with 36,000 days, or a bit shy of 100 years.
