Keto Avocado Smoothie – Peanut Butter & Collagen – Low-Carb & “Ultra Healthy”

The Best Keto Avocado Smoothie Recipe that you can make at home.

Recently we bought a Keto Avocado Smoothie from a popular health food shop near us. But guess what? The smoothie wasn’t Keto at all, so be careful.

After drinking it I felt a little edgy and decided to test my ketones with a ketone meter and they were very low, considering it was also the first meal of the day.

To cut a long story short we loved the taste of it and went about recreating our own version of the Keto Avocado Smoothie, ensuring everything was low-carb and healthy.

Instead of the regular whey protein that the “nutrition” outlet used we used a keto collagen protein that we keep on hand.  As the carbs are all fiber, it also has MCT’s in it to bring up the fat content, and collagen protein is more Keto friendly than whey protein.

I also wasn’t sure if they were cutting corners with the peanut butter part of the ingredients so I made sure that we used 100% natural peanut butter in our smoothie recipe to keep it low-carb and Keto, also avoiding added sugars.

Along with those ingredients, to thicken the smoothie we used two teaspoons of psyllium husk.

Psyllium husk is a great source of fiber and also acts as a prebiotic to feed the good bacteria in the gut.

Our Keto Avocado Smoothie recipe makes 1 serving and has 3g net carbs.

Keto Avocado Smoothie Recipe Ingredients

  • 1 scoop Vanilla Collagen Protein with MCTs
  • 1/2 Avocado
  • 2 teaspoons of Psyllium Husk
  • 1 tablespoon of Natural Peanut Butter
  • 1 1/2 cups of Unsweetened Almond Milk
  • 5 Walnuts, crushed
  • (optional) 1 tbs of Green Tea Matcha

Note: We Added Some Green Matcha to this recipe for extra fat burning and presentation. You can too if you like, but you don’t have to.

  1. This looks delicious! I can imagine that the avocado would add a delightful creaminess to the smoothie. I am going to make this for my breakfast!

  2. This smoothie was great! Eating the keto way, you don’t miss any added sweetners as you taste the sweetness from the vanilla and the nut butter.
