I will be the first to admit that I am a fair weather smoothie drinker. My husband loves them and will happily drink them in the middle of a snowstorm. I need it to be hot and sunny out before I crave an icy drink of any kind.
But this keto protein shake might just change my mind. I cannot get over how refreshing and tangy-sweet it is. I slurped my first one down in a matter of minutes. And then I made them again the very next day!
If you love a cold drink on a hot summer day, you also need to try my Coffee Protein Shake recipe and the fabulous Sugar Free Brazilian Lemonade!
Why we love it
- Thick and rich: Many keto shakes and smoothies suffer from being too thin and watery. But these are indulgently thick!
- Refreshing flavor: That raspberry lemonade combo is so bright and fresh. And not too sweet.
- Easy to make: You can whip up this healthy protein shake in 3 minutes flat.
- Great macros: If you’re looking for more low carb high protein recipes, then these smoothies are for you. 20 grams of protein and only 5g net carbs per serving.

Ingredient Notes
This post may contain Amazon or other affiliate links. As an Amazon Associate I earn from qualifying purchases.
- Frozen berries: Raspberries are my choice, but you could use frozen blueberries or strawberries, or even blackberries! Be sure they are fully frozen as that helps the consistency of the shake.
- Protein powder: Obviously since this is a protein shake, you need protein powder of some kind. I used unflavored whey protein isolate, but check out the other options below.
- Lemon flavor: To keep the carbs lower and to boost nutrition, I skipped the lemon juice and used Ultima electrolyte powder. But you could use a bit of lemon extract or some a packet of True Lemon. Whatever you choose, make sure it has 0 carbs per serving.
- Yogurt: A little Greek yogurt helps give keto protein shakes a thicker consistency and boosts the protein content. If you can find it, I recommend Two Good yogurt as it has fewer carbs.
- Whipping cream: Heavy cream makes it feel more like a rich milkshake!
- Low carb milk: You will need a little bit of additional liquid to help thin it out enough to be pourable. You can use a non-dairy milk, as I did. Or you can mix cream and water.
- Sweetener: Use your favorite powdered or liquid sweetener to sweeten to taste.
Expert Tips
You don’t need me to tell you how to blend smoothies and shakes up in a blender. But I do have some tips for you to get it super smooth and creamy. And also to make it exactly to your tastes!
1. Put the frozen fruit in first. This way, the blades catch it first and really blend it up. I find that if I put in the liquids or yogurt first, I tend to get a few berry chunks.
2. Blend once, stir, then blend again. I have a really good blender, but I still recommend stopping the blender and getting in there with a rubber spatula. Push any chunky pieces down toward the blades.
3. Use crushed ice, not ice cubes. A little ice gives the protein shake added volume but also keeps it colder for longer. But bigger pieces of ice don’t break up nearly as easily.
Make it your own!
You don’t have to make this keto protein shake exactly as I did, although I do highly recommend the raspberry lemonade combo. You can opt for other frozen berries, although that may change the carb count a little.
You can also do other additional flavors besides lemon. Use another flavor of electrolyte powder or use True Lime. Or just use some vanilla extract, because raspberry and vanilla are delicious together. Really, the flavor variations are endless.
Protein Options
I recommend unflavored protein powder, as the flavored varieties can overpower the delicate taste of the raspberries. Many of them also contain added sugars and carbs. You can use whey protein, egg white protein, pea protein or collagen protein for this recipe.
Sweetener Options
The smoothie does not rely on the sweetener for consistency, so you can use what you like best. I recommend a powdered or liquid sweetener to avoid any grittiness.
Because the electrolyte powder has some sweetener in it, make sure you taste the smoothie before you add more.
Dairy Free Option
Yes, you can make this dairy-free too! Use some thick coconut cream and coconut milk in place of the yogurt and heavy cream. Just be aware that the nutritional counts will change and it may be slightly lower in protein.
Frequently Asked Questions
Not all protein shakes and mixes are keto friendly, so it’s advisable to read the labels carefully. Look for shakes that are under 7 or 8 grams of total carbs. Better yet, make your own keto friendly protein shakes at home. It’s easy and you can control the ingredients. They taste far better too!
You can use many forms of protein powder on the keto diet, such as whey, egg white, pea, or collagen. Just make sure the powder you use does not contain a lot added sugar or fillers. I like using unflavored whey protein in my recipes.
The carbs in protein shakes differ significantly depending on the ingredients. This Raspberry protein shake recipe has 7.9g of carbs and 3g of fiber per serving, so it has only 4.9g net carbs.

delicious!
This is my go-to summer breakfast. I love it! I do sub frozen strawberries for the raspberries since I live in a berry-deprived area!
Great tasting recipe – thank you!
This is my go-to recipe for protein shakes, though I usually leave out the electrolytes.
I recently experimented with the recipe; I added frozen pumpkin puree instead of fruit, some pumpkin pie spice (I think a teaspoon or two), half a teaspoon of vanilla extract, a pinch of salt, and…
…it was delicious! Like drinking a pumpkin pie.
Cheers!
I have made this smoothie twice now. It’s is very refreshing and satisfying. Thank you for all your work.
It’s not even noon and the temperature is 85F – this drink is incredible refreshing! Another recipe win as always! Thank you for all of your hard work developing go-to recipes that never fail!
This is delicious! I’ve been searching for a high protein, limited carbs smoothie and this is a great one. I used Ultima Peach Bellini electrolytes and strawberries in place of raspberries.
Refreshing and filling. Thank you!
This smoothie is awesome. I have to heal my gut from accidental ingestion of gluten. I am Celiac, and this smoothie is all I can have right now. It is saving me from being hungry…Thank you
Oh my gosh, I hope you feel better soon. But I am SO glad you like the smoothie.
Love, love love this recipe. I had to freeze my freaks berries to make it. So delicious. Thank you for this and your other recipes.
Going to try this tomorrow. Very much looking forward to it. Thank you for all your work in recipe development. I have been a fan for many years. Love them.
love this protein pick me up in the afternoon
Hello!
Recently found your YouTube videos and am loving them. I made this smoothie
today exactly as written (I did use Jay Robb unflavored egg white protein)
This was absolutely delicious! The lemon electrolyte powder is ingenious. I did not
need to add additional sweetener. But, I drank more than half, whoops.
Looking forward to trying many more of your recipes.
Thank you!
So glad you liked it!
I’m not much of a smoothie fan, but I was on the go yesterday- and needed something FAST! So I whipped this up in my blender for my lunch, and I must say– very, very tasty and it kept my energy going right up until dinner♥
Yay!
Made this for breakfast today, and we really enjoyed it. It is definitely a keeper recipe. It was a little chilly in our house this morning, and I get cold very easily, so I made the smoothie even better by following it with a cup of hot cocoa using your keto cocoa mix…
So Good! I don’t miss the carbs!
Glad you liked it!
This was tart delicious and refreshing on a hot summer day! My kids described it as a glass of yum! Thanks for all you do!
