Chase away the winter blues with this low-carb blueberry smoothie! Made with zero added sugar and full-fat coconut milk, this is the perfect keto smoothie!

Winter Blues Smoothie

So it might be winter, but I have made a bit of a resolution for next month that I’m going to try to get more fresh air and exercise outdoors, at least as much as possible. If I had started this at the beginning of February, I would have called this “Walk-ruary”. Since I’m starting this in March, I’m going to call it…wait…March. I’ll just call it MARCH. (Get it, “march-ing”)?! Ok, that’s lame. But my lame-ness is no surprise to you guys by now!

I asked a few of you on Instagram the other day when I teased this smoothie whether you just save smoothies for the summer time. It sounds like a lot of you make it a year-round thing! Phew! If you had gone the other way I would have second guessed posting this beauty in February!

Thankfully, I can get all gushy on you about it. IT IS SO GOOD.

What makes this a low-carb blueberry smoothie?

For one, this smoothie has no added sugar, AND it’s made with blueberries, known for their low-carb profile! It’s also full of fat. Did I just say that? Maybe not the nicest way to describe something I’m trying to convince you to make, BUT it’s also true. Full fat coconut milk, and full fat Greek yogurt are two of the main ingredients, and the responsible culprits for the oooooh so smooth and creamy texture.

A little bit of lemon juice, a few blackberries, and some sweet, frozen blueberries complete the party.

Can you use fresh blueberries instead of frozen?

If you don’t always have a stash of frozen berries in the freezer like I do, you could definitely substitute the fresh! I would use the same amount as what the recipe calls for, but I’d probably throw in a cup full of ice as well, to get that thick, frosty consistency.

This particular low-carb blueberry smoothie you see here was actually made with wild blueberries, frozen of course. They make for such a beautiful purple color!

Can you use low-fat ingredients instead of full-fat?

If you’re not keen on the full-fat concept, you can definitely substitute with light coconut milk and light Greek yogurt. The smoothie will just be a bit runnier and less creamy, so I would highly recommend trying the full-fat! It makes the smoothie almost a milkshake-like consistency, plus it adds so much flavor! You can also toss in a bit of honey if you like your smoothies on the sweeter side of things and you’re not worried about the carb content.

Did you know I’ve taken photos of this smoothie on 3 different occasions? I was just never happy with the photos. Who would have thought photographing a smoothie would be that difficult? The photos from this post were the best of the bunch.

We’re anticipating another couple of weeks of ridiculously cold temperatures, so you might find me nestled up on the couch in a housecoat drinking one of these smoothies, wishing I was somewhere warm and tropical! I call it the “Winter Blues” smoothie for a reason!

  2. “I’ll just call it MARCH.” Hahaha! Love it!! And this gorgeous smoothie! I don’t have them enough – that needs to change! Pinned!

  3. I am definitely keen on the full fat concept and never buy ‘light’ coconut milk anymore. And I love full fat yogurt and never buy ‘no fat’. Anywho, this smoothie! It not only looks beautiful, it has so many delicious flavours! A definite way to make winter more bearable! Also, love your quirky jokes 😉 Happy Monday! XO

    1. Yaaay I’m glad you’re with me on the full-fat, Dawn. I used to buy “light” everything, but full-fat is WHERE IT’S AT. So much better! Thanks friend, I’m glad you appreciate my terrible humor! Happy Monday to you!

  5. this sounds perfect! definitely tired of apples since we’re in the thick of winter, so i’ll have to put frozen berries in everything.

    1. Right!? I’m tired of apples too! I’ve been buying frozen berries by the bagful, and actually just thawing them and eating them! Thanks Heather!

  6. What a luscious smoothie! Those berries look so bright and cherry for this cold winter. Im finding in the winter I like my smoothies at dinner, in the AM I want something warm lol . But you cant beat all the healthy you can get in one glass. These photos and styling are beautiful. Take care.

    1. Thanks Stacey! I’m all about the bright and happy berries right now – along with citrus! It’s the only thing keeping me from going crazy during the cold. I LOVE that you’re a dinner-time smoothie drinker, haha! You’ll have to try mine out one night. It’s filling enough 🙂

  7. Katherine, this smoothie looks like it would totally beat the winter blues! Love the color and all of the antioxidants of the blueberries! We need all of those we can get during flu season LOL! Thanks for sharing a great recipe!

    1. Thank you sweet Haylie!! We need ALL of the antioxidants these days, ha! We’re currently battling a sickness here, so allllll the berries and vitamin-c for us! Cheers!

  8. I’m totally on board with smoothies year round and my kids are always thrilled when I make them! I’m loving how creamy this looks!
