I've spent a day eating like every living US president. The best diets have surprised me.

Breakfast: Diet Coke

Lunch: Well-done steak with ketchup, side salad, Diet Coke

Dinner: Two Filet-O-Fish sandwiches, two Big Macs, one chocolate milkshake, Diet Coke

Snacks: Diet Coke, Doritos

It was a true challenge to eat like Trump for a day because of all the processed foods in his diet. He also doesn't typically drink coffee — instead, he really likes Diet Coke.

According to a former campaign manager, Trump would regularly go 14 to 16 hours without eating. He usually skips breakfast and sometimes lunch in favor of salty snacks like Doritos before a hefty dinner.

That hefty dinner could look like two McDonald's Big Macs, two Filet-O-Fish sandwiches and a chocolate milkshake.

Did it taste bad? Of course not, it's engineered to taste fantastic.

Did it give me a hangover the next day? Was I angry at inanimate objects for a few hours? Did I sleep like a squirrel on speed? Yes, yes, and yes.

Breakfast: Special K, orange Gatorade

Lunch: Peanut-butter-and-jelly sandwich, orange Gatorade

Dinner: Angel-hair pasta with red sauce

Dessert: Häagen-Dazs vanilla-chocolate-chip ice cream

Snacks: Protein bars, Fig Newtons, orange Gatorade

Biden's diet waffles between childlike and octogenarian with choices like Special K cereal, orange Gatorade, angel-hair pasta, and PB&Js.

He famously loves ice cream and reportedly ensures pints of Häagen-Dazs vanilla-chocolate-chip stay stocked in the White House kitchen.

I'm sure lots of people who aren't 6 or 80 years old eat just like Biden, but I ended the day hungry, craving protein, and bored. The boredom was the most offensive part.

Breakfast: Coffee, apple, bagel with butter

Lunch: A whole pepperoni pizza, side salad

Dinner: Chicken enchiladas, iced tea

Dessert: Peach pie

Snacks: Coca-Cola Jell-O salad

Clinton's diet felt offensive, too, but mostly out of quantity. During his presidency, he famously had quite an appetite and loved eating.

There's no doubt in my mind this man could eat. I was force-feeding myself peach pie for dessert after knocking back more pizza and chicken enchiladas than a 17-year-old football player.

Nothing tasted bad, but it was all too rich and too much. I understand why he later started following a vegan diet.

Breakfast: Coffee and juice

Lunch: Country ham with red-eye gravy (ham drippings mixed with coffee), turnip greens

Dinner: Fried chicken, potato salad, buttermilk

Dessert: Peach ice cream

Snacks: American cheese, deep-fried peanuts

My day of eating like Carter had its high marks. He's lived to be 100 drinking buttermilk and eating fried chicken with potato salad, which brings me great joy. (Not the buttermilk part — drinking that was upsetting.)

During his presidency, Carter famously didn't have much of a sweet tooth but enjoyed peanuts, cheese, and Southern cuisine.

His liquid breakfast and coffee-spiked ham lunch almost made me rank his eating habits lower, but dinner, dessert, and some solid snacks (deep-fried peanuts) raised his marks.

Breakfast: Scrambled eggs, whole-wheat toast, green tea

Lunch: Salad with chicken, tea

Dinner: Chili con carne, roasted broccoli, honey ale

Snacks: Almonds, protein bar, Nicorette gum

The Obamas were known to have some fairly healthy eating habits while in the White House. He's a tea drinker, and although I love it, I'm fully and pleasantly addicted to coffee. It was tough to give it up.

In terms of drinks I did also have honey ale, given that's what he made as the first president to brew beer at the White House.

The food I had was filling, balanced, and solid otherwise (except for the occasional Nicorette gum — Obama is an ex-smoker), but it all felt a little too … healthy. Where's the fun?

Breakfast: Huevos rancheros, coffee

Lunch: BLT sandwich, Lays potato chips, Diet Coke

Dinner: Cheeseburger pizza, black beans, and corn

Snacks: Chex Mix

My day of Bush-inspired eating topped the charts for me. It was fun and not too sophisticated.

Fortunately, he was known to be a coffee drinker during his presidency. I also enjoyed the spicy flair of huevos rancheros, a Mexican egg dish popular in Texas that he reportedly loved.

The rest of his diet was appealing, too, with the only hiccup being cheeseburger pizza topped with beef, bacon, pickles, and cheese, then slathered in ketchup.

If you subtract the ketchup, Bush's eating habits would be my favorite by an even wider margin.
