This is Food Wars.

[STARBUCKS | Highest calories: 470]

If you were to order a Venti caramel Frappuccino from a UK Starbucks, it would contain 426 calories, 61.1 grams of sugar, and 117 milligrams of caffeine.

Harry, your Frappuccino's looking a little sad there, buddy, looks like all your whipped cream melted. So, here's a pro tip from the USA.

470 calories, 74 carbs, 73 of which are sugar, and 120 milligrams of caffeine.

Oh, yuck.

Yuck!

That's what that tastes like?

[SUBWAY | Highest calories: 492]

Well, in the UK, 6 inches of Meatball Marinara comes in at 492 calories.

In the US 6-inch meatball, there's only 430 calories.

Yo. Am I even in the shot when I look at the camera?

Yeah, you are.

[TACOBELL | Highest calories: 530]

Well, in the UK, a Crunchwrap has 578 calories.

But shockingly, it has 60% of your daily saturated fat allowance.

In the US, our hexagram is 530 calories, and is about 6 grams of fat less than the one in the UK.

But, surprise to no one, ours has more sodium.

As is always the case, in the US, you have to look at the beverages.

This right here is a large Mountain Dew Baja Blast.

This is 30 ounces of a liquid that is the most unnatural green I've ever seen.

It glows in the dark. It's so bright, when I close my eyes, I can still see it, like when you look at the sun.

This beverage has over 420 calories.

That is ridiculous. I got to take a sip.

Uh, my body just took a screenshot.

That is ridiculous that anyone drinks more than an ounce of that ever in their lives.

Apparently, people like drinking it. It's very popular.

This has roughly 110 grams of sugar.

Ahem, for the people in back: 110 grams of sugar!

That's way too much sugar for a human being to have in a week.

It's an absurd amount of sugar.

Oh, God, it's like it's horrible, yet I'm addicted to it.

[BURGER KING | Highest calories: 1,600]

For a large Whopper meal, the Whopper itself is 627 calories.

A 180-gram serving of large fries would be 437 calories, and a large Coke would be 209 calories.

That brings the total of a large Whopper meal in the UK to 1,273 calories.

And in the US Burger King, the Whopper meal comes in at a hefty 1,600 calories.

[McDONALD'S | Highest calories: 1.870]

If you are trying to eat healthily at McDonald's, it might actually be the drinks that you have to look out for.

Joe: That's nothing, guys.

Our chocolate shake, 840 calories.

That's as many calories as two cheeseburgers and one hamburger.

If you were to walk into a UK McDonald's and order yourself a large Big Mac meal with a milkshake, it would be around 1,400 calories.

And if you were to get the large Big Mac meal with a chocolate shake in America, the total here is 1,870 calories.

[KFC | Highest calories: 1,980]

If you were to walk into a UK KFC and order a three-piece meal, and they gave you a drum, a thigh, and a wing with a large fries and a large Pepsi, that would come to 1,155 calories.

Our large fry is 930 calories and our large drink is 380, and if you were to order a three-piece with a large fry and a large drink in the US, it would be roughly this many calories.

[DOMINO'S | Highest calories: 2,240]

Let's compare large cheese pizzas in the two countries.

This is what a UK large cheese looks like.

And this is what a large, properly cut Domino's cheese pizza looks like in the US.

It's cut into 10 pieces, and each slice contains 176 calories.

That means that in total, the pizza in the UK is 1,760 calories.

Instead of 10, we got eight slices.

That means each slice is roughly 280 calories, which makes the whole pizza 2,240 calories.

And according to the thing that was written for me, that is almost 480 calories more than the UK large.

[FIVE GUYS | Highest calories: 2,769]

So a plain cheeseburger, regular fries, and a chocolate shake from Five Guys in the US totals at 2,767 calories.

Yo, dog.

Also, I think this is about $70.

The same meal in the UK, well, that comes to a total of 2,769 calories.

Two calories more than in the US.

[PIZZA HUT: Highest calories: 3,760]

Well, in the UK, that's a large stuffed-crust pepperoni feast.

If it is 10 slices, each slice is 292 calories, bringing the total to 2,920.

One of these pizzas contains more than double your daily sodium allowance and more than triple your saturated fat allowance.

If you want to have even more calories in your pizza, then you've got to go with the most calorific pizza on the Pizza Hut menu and, thank you Connor, that is of course the Meat Lovers.

This entire thing is 3,760 calories.

400% of your daily saturated fat. 400.

[PAPA JOHN'S | Highest calories: 4,260]

In the UK, it's a sausage and pepperoni pizza.

Now, for an XXL version of this pizza, each slice is 355 calories.

That brings the total to 4,260 calories.

Most calories pizza, take one, Papa John's.

In the US, if you're going for most calories, it's a tie between the meats pizza, and the pepperoni, sausage, and three-cheese pizza.

Each pizza is roughly 410 calories per slice, and since it's 10 slices per pizza, and since it's 10 slices per pizza, that is a whopping 4,100 calories per pizza.

Both these pizzas look like a nightmare.

I mean, there's a lot of meat on this pizza, especially this one right here.

This is exhausting just looking at this thing.

So of course I'm going to take a bite!

No. No!
