How to Make a Keto Smoothie
Since ketosis is a metabolic state in which you burn fat, (rather than carbs) for fuel, we want to pack keto smoothies full of low-carb, high-fat ingredients.
All good low-carb smoothies have a few basic steps.
- Start with a liquid. Coconut milk, nut milk, yogurt (I make my own Raw Milk Yogurt), heavy cream, water, and herbal teas are safe low-carb choices with great flavor and texture.
- Add a thickener. No bananas for us because they are too high in carbohydrate but we do have other choices like avocado, chia seeds, nut butter, protein powders, or shredded coconut which will thicken the smoothie nicely. The best keto thickeners are healthy high-fat ingredients!
- Pick a flavor. This is usually the fruit part of the smoothie. Berries (blueberries, strawberries, blackberries, boysenberries, etc) are keto-friendly options.
Cocoa powder (cacao powder), pumpkin puree, lemon juice, mint leaf, or cinnamon can also add flavor.
Leafy greens like spinach and kale are common in keto green smoothies. Some recipes use savory foods like cucumber and even cauliflower! (source)
- Enhance with optional add-ins. A scoop of collagen powder or hemp seeds adds a subtle flavor and extra nutrients. Tossing in 1/2 teaspoon of spirulina or chlorella is also tasty. Cacao nibs are fun to top a smoothie with, they have a delightful crunch!
- Blend until smooth. Once all the ingredients are gathered in the blender, flick it on, and blend until the smoothie is well incorporated.
- Serve immediately. Keto smoothies, or any smoothie for that matter, are best served right away. Enjoy!
Keto Blueberry Avocado Smoothie
This keto avocado blueberry smoothie calls for a small bit of sweetener.
I use a homemade stevia extract but you can also substitute with a store-bought brand or erythritol instead. I would recommend a powdered sweetener over granular because it will incorporate much better.
Sometimes the granular options don’t blend thoroughly and leave a gritty texture, particularly in the last few sips. Nobody likes that!
This recipe serves 2. If you only need 1 serving, divide the ingredient amounts in half. If you desire more servings, multiply the ingredients accordingly.
If any leftovers remain, you can freeze them by dividing the avocado blueberry smoothie equally into small sandwich-sized ziplock bags. Place them flat in the freezer. Once frozen, you can adjust them to stand up straight, so they take up less space.
Smoothies don’t last that long in the fridge, therefore, freezing the extra portions is the best way to go. This way, nothing goes to waste, and you will have pre-prepped food, which will save you time on a busy day.
Are Blueberries Keto Friendly?
However, blueberries are also keto-friendly!
Per 1 cup, there are 83 calories coming from 0.5 g fat, 1 g protein, 21 g total carbohydrate, and 17.5 g net carb (source).
We use half this amount for the whole recipe which makes 2 servings. In this keto blueberry smoothie, there are 5.25 g total carbohydrate and 4 net carbs from the berries per serving.
Compared to other commonly eaten fruits, berries are significantly lower in carbohydrates than fruits like apple, banana, pear, and peaches (source).
If you’re interested in keto and low-carb dieting, a low carb berry smoothie is going to be a better option than other flavors.
The Best Avocado Smoothie Recipe
There are a variety of avocado smoothie recipes but I like this one the best. It’s thick and creamy, almost like a shake, the prep time is minimal and I almost always have the ingredients on hand.
In the summer I prefer to use fresh blueberries. In other times of the year, I can pull frozen berries from the freezer and blend them in. Either fresh or frozen blueberries may be used. The texture may be different but the flavor will always be just as delicious.
Using frozen berries makes a more frosty shake, while a fresh berry smoothie will be easily sipped through a straw.
Every keto smoothie with avocado has four similar features: avocado, berries, milk or liquid, and a sweetener.
Together these foods combine into a delicious and healthy drink, that is almost like a dessert!
If you like using avocado as a low-carb desserts, I know you’ll love my 10-Minute Chocolate Avocado Pudding.
Vegan and Dairy-Free
In addition to being ketogenic, containing zero added sugar, and paleo-approved, this keto berry avocado smoothie is also vegan and dairy-free.
Using coconut milk or nut milk is the secret to making any smoothie dairy-free, it’s quite easy once you get the hang of it. These ingredients are also plant-based and naturally vegan too.
