Ketogenic berry smoothie with 3 ingredients
You may be thinking berry smoothies are a big no-no while on the ketogenic diet since most fruit is basically loaded with sugar and carbs. The recommended daily carb intake for keto is around 20 g of net carbs, but just one cup of blueberries contains 17.5g of net carbs (and a cup of blueberries can be eaten in the blink of an eye!)
So how can you make your smoothie keto-friendly? Let’s find out!
The secret to making a low-carb mixed berry smoothie is to keep the number of mixed berries very low, you’re just adding them in for the flavor. That way you can bulk up your smoothie with healthy fats and make it super filling and satisfying while keeping the carb count low.

Keto mixed berry smoothie
What berries are good for the keto diet?
The berries with the lowest net carb count are raspberries (3 g per 1/2 cup) and blackberries (3g per 1/2 cup). Strawberries are also a good option as they come in at 4.5 g per 1/2 cup of berries. The highest net carb count berries that are not really suggested to eat too much on the ketogenic diet are blueberries coming in at a whopping 8.5 g per 1/2 cup.
Is coconut milk keto-friendly?
Coconut milk is a great ingredient for a vast variety of keto recipes, from coconut milk keto smoothies to dinner recipes, and desserts. 1 cup of unsweetened coconut milk contains just 3 g of net carbs and a whopping 36 g of fats!
What can you add to the frozen berry smoothie recipe to make it more filling?
The coconut milk in this mixed berry smoothie makes it satisfying and filling but if you would like to add more keto goodness to your smoothie, here are a few of my favorites:

Avocados – These are the perfect keto smoothie extra ingredient that adds tons of extra fats and contains just 2 g of net carbs per 100 grams. Just make sure you pick a nice and ripe avo to avoid the bitter taste. You could even add some spinach to create a green smoothie.

Chia seeds – Chia seeds are a must for anyone struggling with constipation while on the keto diet. These magic black seeds contain a whopping 5g of fiber per 1 tbsp so go on and add some to your smoothie!
MCT oil – This was the keto supplement I ever purchased and by far my most used one. MCT oil is a type of fat that helps suppress hunger, boosts energy and focus, and improves metabolism. This brand of MCT oil is tasteless and is a great addition to keto smoothies.

Vanilla Extract – A few drops of vanilla extract can really lift up the taste of this easy breakfast smoothie.

Peanut Butter – Peanut butter and almond butter are great ingredients to add to any keto smoothie to boost the fat content of the easy original recipe.

Swap coconut milk with unsweetened almond milk for a lower-calorie smoothie.

Vanilla Protein Powder – This will make the smoothie fluffier and lighter and will boost the protein content without adding many extra carbs. A smoothie with vanilla protein powder works as a great post-workout snack and will help you recover and build more lean muscle mass.
Frozen mixed berries – These are typically made out of strawberries, blueberries, blackberries, and raspberries and contain around 5 g of net carbs in a 1/2 cup serving. If you rather use individually frozen berries, your best bet is raspberries which come in at just 3 g of net carbs per 1/2 cup.

Simple Syrup – This is optional but the smoothie just tastes so much better with some extra sweetness! My favorite keto sweetener that I use in all of my smoothie recipes is Sugar-free Simple Syrup which contains 0 calories and 0 net carbs and doesn’t have that nasty aftertaste that some other sweeteners do.
MCT Oil – I used to never add MCT oil to my keto smoothies and would feel hungry shortly after finishing my smoothie. Since I started to add it into the low-carb smoothies it has honestly made the biggest difference in how I feel.
MCT oil can help with:

Helping you consume fewer calories by making you feel the fuller source
Can help increase fat burning and can jumpstart your metabolism
It metabolizes quickly so is perfect for fast energy release. I often take it just before working out!
