Trump's affinity for fast food is well-documented — he frequently stopped at fast food restaurants on the campaign trail.
During the campaign, Trump often ate fast food from restaurants like Domino's, KFC, and McDonald's aboard his private jet.
Two of his campaign aides described Trump's typical McDonald's order: two Big Macs, two Filet-o-Fish sandwiches, and a large chocolate shake.
Barack Obama also indulged in cheeseburgers — he would occasionally pop into local diners in Washington, DC, to grab one.

Before becoming president, Trump regularly ate at the Trump Tower Grill in Manhattan. His go-to meal was steak prepared well-done with ketchup, but in one infamous photo from 2016, he opted for the taco bowl.
His diet on the road wasn't so different — a photo that circulated in 2015 showed Trump chowing down on a pork chop on a stick at the Iowa State Fair.
Obama was frequently seen incorporating vegetables into his diet.
And he promoted nutritious cooking at White House events, like the Healthy Lunchtime Challenge & Kids' State Dinner in 2013.

As for exercise, Trump's primary form of physical recreation is golf. He's made 100 visits to his golf properties since taking office in January 2017.
In one memorable instance, he was filmed driving his golf cart onto the green — a cardinal sin of golf etiquette. The moment gave ammunition to critics who said Trump doesn't exercise enough.

But Obama's favorite sport is basketball. He played frequently with White House officials and staffers, and especially with his personal assistant Reggie Love.
Love said Obama woke up before 5 a.m. most mornings to exercise. Trump typically spends his first few hours of the day watching cable news.
Obama was regularly photographed being physically active.
But Trump may be changing his ways. Last month, people close to Trump said the president has started to eat more salad, fish, and soup, and less red meat, according to a Bloomberg report.
