What ingredients do I need for a keto smoothie recipe?

The driving factor behind nutritional ketosis is carbohydrate restriction. That means the key to making a keto smoothie is choosing low carb ingredients. 

This can include low sugar keto fruits, such as berries and avocado. Swapping out juices for water or nut milk. Opting for some fibrous green veggies in lieu of mangos and bananas. Using fewer ingredients overall or simply smaller quantities will also reduce the carb count.

Carbs in Smoothies: Why are the total carbs on my keto smoothie so high?

Yes, fiber is technically a carb. But unlike it’s best buds starch and sugar, fiber is largely unabsorbed by the human body. That means when we eat most fibers, it’s not directly impacting our metabolism or influencing ketosis. If we’re reducing carbs to reach nutritional ketosis and/or fat adaptation, it doesn’t make a lot of sense to nix fiber because you’re bogged down in semantics. Does it?

This is where the idea of net carbs comes into play.

Net carbs = Total Carbs – Fiber

Net carbs will give you an approximation of the carbs that will impact your metabolism, and in turn, ketosis. If you’re worried about high total carbs, take a peek at the fiber content to see how it balances out. If you’re using relatively low carb ingredients, like fibrous, non-starchy veggies and low sugar fruits, you’ll be just fine. And your friendly gut bacteria will thank you for it!

Many people will automatically stop drinking keto smoothies due to the high total carbs in smoothies. Don’t worry so much about carbs in smoothies when the majority of carbs are coming from fiber.

What’s the best time to drink smoothies?

Maybe it’s because I’m always flying out the door with little time to cook or perhaps the loud buzz of the blender grinding me out of my sleep stupor, but I’m partial to keto smoothies for breakfast. 

Smoothies are also great for pre-workout or post-workout! Perfect for a meal that’s not too heavy if you need something in your stomach before you hit the gym. Or after the gym, load it up with some whey protein or Greek yogurt to help your recovery. If you’re someone who works out a lot and incorporate strategic carb intake around your physical activity (e.g., TKD), smoothies are also an excellent way to deliver those quick digesting carbs for energy and performance.

TLDR; Smoothies rule. Keto smoothies are just as easy, delicious, and nutritious as their high carb counterparts. Here’s a recipe!

    Thank you so much for the recipe ! I was looking for a low carbs and high protein smoothie and this one is perfect ! The list of ingredients that you can use is very useful as well. Is it possible to use soy milk too ?

    Problem with keto is to get the fat percentage high. Would love to have a smoothie recipe which has 75% fat calories. Besides coconut oil (controversial as far as healthy or not) I have not seen many other options in most keto recipies. My theory is to go with a “olive oil vinegrette” flavor motif instead of the sweet/dessert. Could base smoothie on salad greens/kale/ spinach/tomato and add olive oil with wine vinegar, salt and pepper, basil. Add a bunch of olive oil to get to your keto diet fat goals.

    • Just depends on your goals! Keto relies on carb restriction first and foremost. I’m going to drop a couple resources below just in case you’ll find them to be helpful and give a different perspective. 😊

      That 75% from fat calories can be a bit of a misnomer, it’s certainly not required for each meal or even daily intake if fat loss is the intended goal. It can be a little confusing at first because the ratios get thrown around a lot. But there are some great resources out there that break down keto macros for different purposes. Keto: A Woman’s Guide & Cookbook has a couple chapters focused on it. There are also a few articles on the site and this quickie little video can help visualize it too:

      If you scroll down past the keto calculator on the page, there is a bit more detail as well. Hope you find it to be helpful!

      But yes, if you do need high fat for your goals there are loads of things to consider besides olive oil. I love your savory vinaigrette suggestion, that’s brilliant! Coconut milk, coconut oil, avocado, nut and seeds are just a few others that can fit the bill. Have an awesome day! ❤️

    • Olive oil can be used in sweet smoothies as well. I add tablespoon to my smoothie bowl every morning which is sweetened with pure stevia extract. Olive oil also works very well in a chocolate smoothie.
