Low Carb Smoothies [Keto, Sugar-Free]

Low-carb smoothies can be a great way to pack nutrient-dense ingredients into your diet. However, the traditional variety can be packed full of sugar and carbohydrates. By choosing the right ingredients, you can keep the carbs down and make smoothies a part of your keto routine. This smoothie recipe is from my latest book, Keto: A Woman’s Guide & Cookbook.

Keto: A Woman’s Guide & Cookbook

If you haven’t picked up your copy of the book yet, be sure to check it out. I fill you in on all the details required to succeed on keto, from beginner to advanced strategies. There’s nothing out there quite like it, as it’s geared towards optimizing body composition based on female physiology and hormonal balance. Complete with recipes to boot (including this low-carb smoothie!), so you’re not completely lost in the kitchen. If you’ve tried any of my other recipes before, you already know these are delish!

And if you have picked up a copy, then I want to extend a heartfelt thank you. Having the opportunity to write about my passion has been a dream come true. I genuinely appreciate your support! If you could do me a quick favor and take just a minute to leave a review on Amazon letting me know your favorite part of the book, that would be incredible. It really helps to spread the word and gives others insight into whether or not the book will be a good fit. It also helps the book appear in search results instead of drifting off into the depths of Amazon’s millions and millions of titles. This is hands down the best way to support the book! Thank you for taking the time to leave your thoughts!

Make yourself one of these low-carb smoothies, grab your copy of the book, and get to reading!

Real Reader Review

Here’s what one reader Marissa A. had to say: 

“Great recipes, refreshing perspective! I’ve been following Tasha since the beginning of my keto journey. This book is honest and clever, just what her readers have come to expect from her. However, she offers a fresh perspective on keto that many others overlook; dieting is different for women! It just is and she gets it. Recipes are delicious. Don’t miss out!”

Very low-carb smoothies

To keep the carbs super duper low, it’s all about selecting low-carb ingredients for your smoothies. I have an entire keto smoothie guide for more ideas to experiment with, but here’s the gist: low sugar fruits, fibrous non-starchy vegetables, and unsweetened liquids. 

What is the lowest carb fruit?

Olives, avocado, rhubarb, and starfruit are fruits that are all extremely low in carbs. However, they are a bit more savory than your typical smoothie fare. If you’re looking for sweeter low-carb smoothies, you have some options!

Berries are quite a bit sweeter, but they still have a relatively low amount of carbohydrates. The berries with more seeds (think: blackberries, strawberries, etc) are a particularly good option for keto as they tend to be more fibrous, in turn lowering the net carb count and contributing to satiety. Plus, they taste great in a low-carb smoothie!

Are bananas good for keto?

Not exactly. Carbs in banana quickly add up, which is not conducive to ketosis in higher quantities. Skip the banana for your low-carb smoothies and consider an avocado instead! 

Filling Low Carb Smoothies

Smoothies certainly aren’t well known for their filling, appetite suppressing qualities. But that’s because most smoothies are heavy on the sugars and juices. If you want a smoothie that will keep you full, consider bumping up the protein or fiber. 

Also, adding low-carb protein powder or high fiber ingredients like flaxseed or psyllium husk can help make your low-carb smoothies feel like a satisfying meal.
