Trump Diets by Eating Dover Sole and Half of a Bun, Rudy Giuliani Confirms

President Donald Trump's chosen diet to lose some weight, as his doctor advised, reportedly has been to eat his preferred fish, Dover sole, instead of steak, and half instead of a whole bun.

White House physician Dr. Ronny Jackson in January announced that Trump, at 6 foot, 3 inches tall and 239 pounds, was one pound short of being classified as "obese" and should drop 10 to 15 pounds. Trump has apparently sacrificed regularly eating his favorite McDonald's meals in order to meet that goal.

Regulars at dinners Trump has with Cabinet members, advisers and dignitaries from abroad note that well-done steak has been swapped for Dover sole, according to CNN. A Walter Reed National Military Medical Center dietitian worked with White House chefs earlier this year to cut down on calories and fat in the president's dishes, a source familiar with the issue told the media outlet. Trump is also being served vegetables.

Trump reportedly ordered Dover sole for dinner recently instead of his go-to steak at Trump International Hotel.

Earlier this month at Trump National Golf Club in Virginia, Trump ate a well-done burger with only half of a bun, while his lawyer Rudy Giuliani ate a Cobb salad, according to The Washington Post.

"I do that, too, sometimes," Giuliani told the newspaper, referring to half of the bun. "It's a good way to do it."

The president's reformed diet appears to date back to at least early March, when several people familiar with his eating habits told Bloomberg that he had been consuming more fish, salads and soups, rather than red meat, and that he took a two-week hiatus from hamburgers.

Trump's typical menu on the campaign trail was two McDonald's Big Macs, two Filet-O-Fish sandwiches and a chocolate milkshake.

While Trump has modified his diet, he doesn't seem to have added more to his exercise regimen other than continuing to golf.

"He is more enthusiastic about the diet part than the exercise part," Jackson said of Trump at the time of his physical examination report.
