When you’re looking for a low carb keto protein shake that’s thick, creamy, and fruity, add this one to your list! It’s made with just 7 basic ingredients and is ready for slurping in a matter of minutes.

Are Protein Shakes Keto?

There are keto friendly protein shakes out there, but many of them are filled with artificial preservatives and processed ingredients — and many other protein shakes are not suitable for a keto diet at all, as they are loaded with sugar. That’s why I prefer to make my own homemade sugar-free protein shakes.

While I’m not a big fan of meal replacement shakes instead of actual keto meals, some people do have success with keto protein shakes for weight loss. And even if you’re not replacing a meal with this shake, it’s totally delicious as a snack or light keto breakfast.

Ingredients You’ll Need

This section explains how to choose the best ingredients for keto protein shakes, what each one does in the recipe, and substitution options. For measurements, see the recipe card below.

  • Berries – I used a combination of strawberries, raspberries, and blueberries. Other keto fruit, such as avocado, can also be added. For an even thicker smoothie, use frozen berries.
  • Collagen Protein Powder – I like using this collagen or this one, but any protein powder you like (whey protein, pea protein, etc.) is fine. Just make sure it is sugar-free and has zero carbs. I use 3/4 cup powder for the entire keto protein shake recipe, which is about 6 scoops (1 per serving).
  • Full-fat Coconut Milk – Makes the low carb protein shake thick, rich, and creamy, without dairy. You can use other keto milk options, such as unsweetened almond milk or hemp milk, but the shake will be less thick.
  • Wholesome Yum Keto Simple Syrup – Sweetens the low carb protein shake with zero net carbs, zero aftertaste, and zero gritty texture. You can also use Besti Powdered instead, which dissolves easily, even in cold drinks like this one. Most other sugar substitutes will not dissolve fully, leaving a gritty texture and uneven sweetness. The smoothie is not sweet enough for most people without any sweetener added, but you can certainly try it (and add some in later if you change your mind!).
  • MCT Oil Powder – Optional, but adds a boost of healthy fats for keto, while being more gentle on the stomach than regular MCT oil. If you prefer, you can use melted coconut oil instead.
  • Lemon Juice – Brings out the sweetness in the berries.

Storage Instructions

  • Store: Keep homemade keto protein shakes in the refrigerator. Give them a blend or shake before serving.
  • Freeze: Pour in a single serving jar, leaving some space at the top to leave room for the low carb shake to expand as it freezes. Thaw overnight in the refrigerator, and shake or blend before serving.
