Ingredients for keto green smoothie

What you’ll need: 

Avocado – Rather than bananas or other frozen fruit, this smoothie gets its thick, creamy texture from avocados. Adding diced avocado provides a good source of heart-healthy fats and fiber to boost satiety while helping to balance blood sugar. 

Spinach – Fresh spinach works best for this green smoothie, but thawed frozen spinach can also work. Adding fresh spinach provides a beautiful color while boosting the fiber and vitamin C content of the recipe. It is such a versatile vegetable to add to any blood-sugar friendly smoothie because of it’s neutral flavor.

Cucumber – This tasty fruit is full of nutrients and water to make your smoothie taste even better, and it has less than 2 grams of carbs in half a cup. Be sure to peel the cucumbers first for a smoother texture. 

Sugar-free almond milk For a creamy frozen smoothie without all the carbs and sugar, sugar-free almond milk works perfectly in this recipe.  

BroccoliRaw broccoli adds a mildly refreshing taste and satisfying green color. Not only does it help to thicken the smoothie, but broccoli provides a good source of fiber, vitamin C, and calcium.

Keto Green Smoothie process

How to make a keto green smoothie:

This green smoothie couldn’t be easier to make.  When it comes to achieving the right texture, having a high-speed blender is a must for this recipe. Blending fibrous veggies like broccoli and spinach can take some work, but with the right blender or food processor (and the right combination of ingredients), you can easily achieve a silky smooth texture. And this keto green smoothie gives you just that! 

  1. Place avocado, spinach, cucumber, almond milk, lemon juice, broccoli and mint in a blender.
  2. Pulse until smooth. For a thicker consistency, add ice cubes or use frozen avocado slices.
  3. Serve with fresh mint and enjoy!


Can this smoothie be made in advance?

Yes! One of my favorite time savers for busy mornings  is to meal prep smoothie bags. Add together avocado, spinach, cucumber, and broccoli into a freezer bag, seal, and place in the freezer until you are ready to blend. When you are ready to make your smoothie, just dump the freezer bag contents into the blender, add the almond milk, lemon juice and mint, and blend! In less than one minute, you have a delicious keto green smoothie ready to go!

How can I make the smoothie sweeter without increasing the carb content?

You can always add a sugar-free, low-calorie sweetener, like erythritol or stevia

Can you lose weight by drinking smoothies?

It depends on what’s in the smoothie. If you want to lose weight by drinking smoothies, they need to be lower calories while providing a good source of protein and fiber. Smoothies that are mostly juice and tons of fruit won’t keep you full between meals and will only spike your blood sugar. That’s why this smoothie recipe combines slow-digesting carbohydrates with fiber, protein, and fat to provide optimal blood sugar balance. 

Is this keto green smoothie good for people with diabetes?

Green smoothies can be a great option for people with diabetes as they are low in sugar and high in fiber. The low carb count along with healthy fats will help keep the blood sugars stable while satisfying your sweet tooth.

Why this recipe works for people with diabetes

In general, low carb keto recipes are great for people with diabetes since they have little impact on blood sugar levels. In addition, this smoothie strikes the perfect balance between carbs, fiber and healthy fats to help you feel full for longer, while providing steady blood sugar and energy levels. 

This green smoothie also has half the amount of sugar as your typical smoothie since it’s made with vegetables and healthy fats. Other smoothies call for fruits high in carbohyrates but this green smoothies focuses on fiber-rich vegetables like spinach, or other leafy greens, avocado, broccoli, and cucumbers. 

With no added sugars, it has a sweet undertone from almond milk and fresh mint. So while they’re just as tasty, this recipe is actually much healthier for people with diabetes who are working to prevent post-meal glucose spikes.
