He might have the resources of the world's richest country at his fingertips, but Donald Trump's favourite meal is a humble Big Mac, or two of them.
According to a soon-to-be-released book, Mr Trump's triumphant march to the White House last year was fuelled largely by fast food.
The book, called Let Trump be Trump, is co-written by Corey Lewandowski, who was fired as his campaign manager in June last year and David Bossie, another top aide.
It details life on the campaign trail with Mr Trump, a life that was peppered with expletive outbursts, staff getting "their faces ripped off," and fast food.
According to the book a regular dinner for Mr Trump was "two Big Macs, two Fillet-O-Fish, and a chocolate malted [shake]."
The book states four food groups were represented on his campaign plane, nicknamed Trump Force One: "McDonald's, Kentucky Fried Chicken, pizza and Diet Coke".
It's not just fast food the US president has a hankering for, the Washington Post reports the plane's cupboards were stacked with Vienna Fingers, potato chips, pretzels and many packages of Oreos because Mr Trump, a renowned germaphobe, would not eat from a previously opened package.
The book says "the orchestrating and timing of Mr Trump's meals was as important as any other aspect of his march to the presidency," and it describes the elaborate efforts that Lewandowski and other top aides went through to carefully time their delivery of hot fast food to Mr Trump's plane as he was departing his rallies, the Washington Post reports.
Both authors said there were times they wanted to parachute off Trump Force One because of the way they were treated.
"Sooner or later, everybody who works for Donald Trump will see a side of him that makes you wonder why you took a job with him in the first place," they wrote.
