Smoothies are one of my favorite things to make. They can be made for breakfast, lunch, or dinner, and they’re great for a pre-workout boost or post-workout to help my muscles recover.

They’re also super easy to make—you can whip most of them up in a minute or two.

What is a diabetes-friendly smoothie?

This list of diabetes-friendly smoothies includes delicious, easy recipes that are low in carbs and don’t have any added sugar. Bonus points if they pack in some protein and are a good source of fiber.

I made sure that the low-carb smoothie recipes you’ll find here have: 

  • less than 20 grams of carbs per serving (mostly from low-glycemic carbs like berries and low-carb vegetables)
  • protein (from 5 to 36 grams per serving!)
  • healthy fat (to keep you feeling full)

These guidelines should help you blend a smoothie that doesn’t give you a blood sugar spike after drinking it! 

Diabetes-Friendly Smoothies and Protein Shakes

Whether you like your smoothies rich and creamy, like a delicious dessert, or fruity and cool for a warmer day, I have put together a list of low-carb and diabetes-friendly smoothies for you to enjoy. 

Creating your own low-carb smoothie recipe

Crafting a diabetes-friendly smoothie is easy if you include nutritious and tasty ingredients that will keep you full without leading to a glucose spike.

Protein

Protein has minimal impact on blood glucose and slows the rate at which glucose enters the bloodstream, which can help prevent blood sugar spikes after drinking a smoothie.

You can add protein to your smoothie by using ingredients such as:

  • Nuts and seeds add both protein and healthy fat. A little goes a long way, as nuts and seeds are generally very high in calories.
  • Greek yogurt and other high-protein dairy products are excellent bases for a healthy smoothie. Just choose plain versions to avoid added sugar.
  • Tofu may seem like a strange ingredient in a smoothie, but it’s high in protein and has almost no flavor of its own, making it an excellent addition.
  • Egg whites can be blended to create “foam, ” making the smoothie or protein shake light and airy. Always use pasteurized egg whites.
  • Unflavored Protein powder can be added to any smoothie to increase the protein content.

Healthy fat

Dietary fat is even more effective than protein at slowing down the absorption of food in the stomach and intestines and, therefore, preventing blood glucose spikes.

Good sources of healthy fat include:

  • Avocado is a good source of both healthy fat and fiber (and it’s delicious).
  • Coconut milk or coconut cream can be added for extra creaminess.
  • Full-fat dairy products. I typically use Greek yogurt.
  • Seeds, nuts, and nut butter. A tablespoon or two is enough.

Fiber

Soluble fiber dissolves in water and forms a gel-like substance in your stomach, slowing down digestion. This helps you feel full for longer and helps control your blood sugar and cholesterol.

You can add fiber to your smoothie by using:

  • Leafy greens like kale and spinach are high in fiber. I prefer the “baby” versions, as they are more tender and blend to a smoother consistency.
  • Seeds like chia, hemp, flax, and pumpkin are excellent sources of fiber. When you read the nutritional label, they may look like high-carb foods, but the carbs are all fiber, so they don’t spike your blood sugar.
  • Fruits and berries can be high in fiber, but you need to look up their nutritional info. Avocados, bananas, apples, and all types of berries are rich in fiber, while melons, oranges, and apricots aren’t.

Sweeteners

I prefer to get the sweetness from the smoothie’s natural ingredients, but sometimes, that’s not possible, and you have to add a sweetener.

My go-to sweetener is Stevia. I explain why in my article The Best Sweeteners for People with Diabetes.
