Banana Bread Fab 4 Smoothie

Extra Thick Banana Bread Fab Four Smoothie

All the notes of a thick slice of banana bread, only in smoothie form! The nuttyness of the walnut butter pairs perfectly with the sweetness of the banana.

And the best part? This Fab Four smoothie, unlike a slice of normal banana bread, will leave you feeling full, calm and energized for hours. Thanks to the magic of blood sugar balance!

Walnuts are rich in vitamin E, omega 3s, antioxidants and zinc. Be Well protein powder is formulated with minimal ingredients and uses a non-chemical extraction process. It’s good for the gut, skin, joints and tissues. Flax seeds are high in both fiber and omega 3s. They feed the “good bugs” in your gut, making for a stronger and more robust microbiome.

I created The Fab Four – protein, fat, fiber and greens – as my easy to remember and lightly structured formula to ensure nourishment and blood sugar balance at every meal. This Banana Bread smoothie works because the Fab Four are able to blunt the blood sugar spike that might otherwise be caused by eating a banana (a higher sugar fruit). Instead, the Fab Four elongates the blood sugar curve, which means you’ll feel energized and calm rather than spike, crash, hangry in a few hours.

Looking for an actual banana bread that’s protein rich and low in carbs? Heather’s Famous Grain Free Walnut Protein Banana Bread is my family’s go-to recipe, and it’s beloved by everyone from me and Chris to our littlest eaters!
