WTF Is Protein Diet Coke?

If you’ve watched The Secret Lives of Mormon Wives on Hulu, then you definitely know Swig, the OG home of the dirty soda. It’s no secret that Utah is the home of this soda delicacy, which is essentially just a cup of soda with cream, and sometimes even flavored syrups. The creamy drink serves as a caffeinated replacement for coffee and tea, as many Mormons in Utah don’t consume them due to religious beliefs. Recently, a new variation of dirty soda has blown up in Utah and made its way to TikTok. It’s called Protein Diet Coke, and soda lovers everywhere (not just in Utah!) can’t get enough of it. I know, it doesn’t sound good on paper, but once you see it (and taste it!), your mouth will be watering.

What is Protein Diet Coke?

As demonstrated by Meredith Hayden (or Wishbone Kitchen on TikTok), Protein Diet Coke is a mixture of Diet Coke and a protein milkshake, specifically the Core Power Fairlife shake. It’s really simple to make: just pour your Diet Coke into a glass (over ice if you want it extra crispy), and then add “a splash” of your protein shake. If you like your dirty soda extra creamy, throw in a hefty splash. It seems that most people use a vanilla shake flavor, but I bet others would work too, like strawberry.

I’m not going to lie, the mixture kind of looks crazy at first. It’s sort of a murky brown color, which is really unappealing. But after your first sip, you’ll be left speechless. 

What does Protein Diet Coke taste like?

It tastes similar to a root beer or a Coke float, which makes sense given you’re combining soda and some type of dairy. In fact, it’s been compared to the aftermath of a float: when the ice cream is all melted and you’re just left with the soda and melted liquid. Wishbone Kitchen describes it as “Yummy, yummy, in my tummy,” so it must be good. In fact, she woke up the next morning after trying it and immediately made another one. 

Protein Diet Coke is a great drink to satisfy your sweet tooth while also getting in your protein. You can even try it with different sodas if Diet Coke isn’t your thing. TikToker Yana Jones replaced the Diet Coke with Dr. Pepper, and it looks even better. But maybe I just think that because Dr. Pepper is my favorite soda. Either way, there’s so many twists you can put on the Protein Diet Coke. 

TikToker Rebecca Gordon tried the viral drink at a Utah gas station, which feels like the most authentic way to drink it. She gave the Protein Diet Coke a 10/10. I seriously need to try it.
