It's not exactly a surprise that Donald Trump doesn't make the best choices when it comes to food. (We all remember that time he put ketchup on his steak, don't we?) But thanks to a new book called Let Trump Be Trump, written by former campaign manager Corey Lewandowski and former aide David Bossie, we now know just how bad the president's diet really is.

“Trump’s appetite seems to know no bounds when it comes to McDonald’s, with a dinner order consisting of two Big Macs, two Filet-O-Fish, and a chocolate malted," they write.

Lewandowski and Bossie, who have both traveled with Trump, write that Kentucky Fried Chicken, pizza, and Diet Coke were also staples on "Trump Force One."

Upon hearing this information, we took it upon ourselves to rank 45's favorite food in order of unhealthiness. Without further ado, here they are.

4. Pizza

Pizza sometimes gets a bad rap, but it really isn't that bad for you if it's made with healthy ingredients and not slathered in grease from a chain restaurant. (Although we're willing to bet Trump usually goes with the latter.) Just try to opt for whole-wheat slices, and don't be weird and just eat the toppings, as Trump says he does. The dough is there for a reason. (Though we can't fault Trump for eating pizza the wrong way, like he did when he was advertising stuffed crust pizza in 1995).

3. Diet Coke

We know that Diet Coke isn't great for you. A study published earlier this year in the journal Stroke found that drinking the stuff regularly could lead to an increased risk in stroke and dementia. It can also lead to weight gain in people over the age of 65, according to a study published in The Journal of the American Geriatrics Society. (And considering Trump is 71, maybe it's time he switched to water.)

2. McDonald's

The Atlantic actually did the work for us on this one. The above meal of two Big Macs, two Filet-O-Fish, and a chocolate malted comes out to 2,400 calories.

"The 3,400 milligrams of sodium more than doubles the American Heart Association’s recommendation of 1,500 milligrams per day. The meal provides almost no fiber—and also offers more white bread than anyone would do well to eat in a week. This is all ominous for the president’s cardiovascular system," The Atlantic writes.

Additionally, the USDA recommends a man of Trump's age should consume about 2,000 to 2,200 calories a day. This one meal alone totals up to be more than someone should be eating in a 24-hour period.

1. KFC

While we don't know exactly what the book says about his specific order at KFC, we're going to base our numbers on this picture Trump tweeted in 2016.

That bucket is big. This leads us to believe 12 pieces of fried chicken could very well fit in there. He's also got a tub of gravy and a mystery tub probably containing mashed potatoes. It's also clear he's already gone to town on his meal, so we're assuming there was more food when he started, and the KFC website backs us up on this. According to their website, a 12-piece bucket meal comes with three large sides and six biscuits, and feeds six. Six! And we're willing to bet he didn't share either.

Next time you're feeling chicken, make this spicy ground chicken and vegetable stir fry:

Assuming he ate the whole thing, a 12-piece variety bucket of extra-crispy thighs, drumsticks, wings, and breasts (we covered all bases) comes out to 4,800 calories, according to KFC's nutrition guide. One serving of gravy is 245 calories, six biscuits is 1,080 calories, and mashed potatoes with gravy is 120 calories (there's less gravy there), which, combined with the chicken, adds up to a whopping 6,245 calories. We don't know which other sides Trump got, but we're going to stop there because we're feeling a little nauseous right now. This is definitely the worst of his choices.

(Of course, chicken isn't bad for you if it's not drowning in sauce and sides. Here are 50 ways to prepare chicken the right way.)
