Protein Smoothies for a Low Carb Diet

Protein Smoothies for a Low Carb Diet

I’ve been playing around with high protein smoothies in an attempt to get a mix of low carb, low sugar ingredients that will allow the smoothie to do three things:  taste good, be compliant with a low carb diet, and keep energy levels high until lunch.  The recipe below does all three!

It took me a while to buy in to the smoothie trend, but I’m fully on-board now, as long as you leave out the bananas and high fructose fruit and the high lactose dairy.  Smoothies can be a great way of getting leafy greens and protein into our diets, both of which have a high correlation with weight loss success.

  • 1/2 cup unsweetened coconut milk
  • 1/2 cup frozen berries can use blackberries, blueberries or strawberries for best taste
  • 1/3 cup Whey protein powder should be a whey isolate- Isopure, Premier, or MuscleTech are good brands
  • 1 tbsp chia seeds optional
  • 1 cup fresh spinach I use 1-2 handfuls
  • 1 cup water can use more or less depending on desired thickness
  • 1/2 cup ice cubes can use more or less depending on desired thickness


  • Blend it all up together, pour  in a glass and enjoy!  Remember to run hot water in your blender right after making the smoothie so that cleanup is easy (it’s hard to clean if you let it sit without water).

Compliant Substitutions or Add-ins for Basic Protein Smoothies:

I never get tired of protein smoothies for breakfast and look forward to the basic one above one each morning.  If you do get bored with the same thing every day however, here are a range of low-carb compliant ingredients that you can substitute in to the above standard (or simply add in):

  • avocados
  • romaine lettuce instead of spinach
  • undistilled apple cider vinegar (if you have digestion issues or flatulence)
  • peanut butter (not much, it’s dense in calories)
  • cottage cheese (high protein)
  • MCT oil, or coconut oil
  • cacao nibs

Enjoy!  If you want to know more about low-carb diets and/or need support, accountability or information from someone who has “been there, done that”, I would love to share and help as your personal online diet coach.  If low carb is not your thing, there are plenty of other types of coaches available (vegan coaches, vegetarian coaches, Bulletproof coffee coaches, etc.)  Try it out!  The first 3 days are free with any coach.

What blender would you recommend for these protein shakes?

Hy Crystal, Vitamix is the go-to blender of most people that use blenders a lot, mostly because it has a real work-horse motor and lasts forever. It is expensive however. If you use ice and frozen fruit in your smoothies a lot, then Vitamix is the way to go. If you work with softer fruit and don’t need an ice crusher, then any blender works fine.

Sounds good but does it only have 2 grams of Protein?

No, one scoop of protein powder has 20-30 grams protein, depending on which brand you use. The program I used for analysis must have skipped the protein powder because it didn’t recognize the brand (and I didn’t notice that!). I’ll fix it pronto! Thank you for the comment and letting me know! ** the corrected nutrition analysis that is currently listed comes from Myfitnesspal.

Ooo. Haven't tried chai seeds in a smoothie yet. I'm pinning this one!

Yes, and something I’ll also add is a tsp of cinnamon sometimes. It helps a (tiny) bit with weight loss but it also helps with the taste. Some of the protein powders taste better than others. Just be careful not to do more than 1 tsp/day as it is a blood thinner.

Yum! I love this, Dorothy! I’m a single mom to a very active premed so we DEPEND on smoothies in the morning to start our day! I also like to use coconut water for the liquid and sometimes treat myself to a chocolate peanut butter smoothie using chocolate protein powder, nanas, and pb! Mmmm
