This ABC Science article by Dr Karl S. Kruszelnicki claims
Before he died, Elvis was eating about 100,000 calories per day!
...
The basic element of Elvis' daily food intake was a 30-cm long bread roll, stuffed with bacon, peanut butter and strawberry jam. Each one had 42,000 calories, and in his final days, he ate two of them per day, together with little midnight snacks of hamburgers and deep-fried white bread.
That seems pretty extreme. I remember hearing that Michael Phelps was only eating ~12k when he was at his prime, and I read that winners of the Nathans Hot Dog Eating Contest only eat on the scale of 25k. To me this sounds like an error.
Was Elvis consuming 100k (dietary) calories per day towards the end of his life?
