Tips for Making Keto Smoothies

I’ve made a hundreds of low carb and keto smoothies over the years! Here are some of our top tips for you that we’ve picked up along the way!

  1. Use Greek yogurt – Greek yogurt is a great way to add protein and make a smoothies creamy without adding sugar.
  2. Low carb liquids – The easiest way to make a smoothie keto friendly is to use the right liquid! I recommend using sugar free milk, cold brew, or water! Avoid any kinds of juices.
  3. Load it up with veggies – Veggies are a great way to add volume and nutrients to your smoothies without adding excess carbs. This is also key to making high fiber smoothies!
  4. Avoid fruit – Sadly, fruit is the biggest culprit of carbs in your smoothies. Avoid adding fruit and you’ll be good to go! This is also key for making diabetic smoothies!

1. Fruit-Free Peanut Butter Chip Smoothie

This peanut butter chip smoothie is made with flaxseed meal, cacao nibs, and raw zucchini. There’s no fruit and so as long as you use unsweetened almond milk, it’s a great low sugar smoothie. This recipe is also one of our favorite almond milk smoothies!

2. Keto Avocado Apple Coconut Smoothie

This is one of our favorite keto smoothies because of the combo of avocado and coconut! It has lime juice, collagen powder, and MCT oil. The only source of carbs are from two slices of apple which isn’t enough to make it not keto friendly.

This peanut butter smoothie is one of the best keto smoothie recipes on our list! If you like the magic combo of PB and chocolate, give this one a try. This is a really high calorie smoothie so keep an eye on the quantity you drink! If you want to make your smoothie smoother and lower calories, you can use coconut milk instead of heavy cream.

5. Keto Banana Smoothie

This recipe might have bananas in the name, but it uses banana extract which is a great healthy way to make a smoothie sweeter! This recipe uses protein powder and MCT oil which makes it a great source of protein and healthy fats.

This avocado pineapple smoothie is a bit borderline, but it’s just under 5g of carbs per serving so it is technically keto friendly! I’d recommend cutting the frozen pineapple in half just to be safe. The heavy cream in this one is great at keeping smoothies from separating!

9. 3-Ingredient Keto Strawberry Smoothie

This might be the easiest keto smoothie recipe on this whole list! It’s only 3 ingredients plus some ice! It’s mostly sugar free milk and some strawberries. The liquid and ice makes a thinner smoothie than most.
