One of the biggest reasons for their lack of staying power? Not enough protein. Adding 1 to 2 tablespoons of protein to each serving of smoothie along with a good dose of healthy fat and fiber will elongate your blood sugar curve and ensure that you’re satiated through lunchtime. Here are a few of our favorite ways to amp up the protein in each glass:
1. Add nut and seed butter.
Two tablespoons of peanut butter contains 8 grams of protein; 2 tablespoons of almond butter contains 7 grams. Nut butter will also help your smoothie have a creamy, thick texture and can do wonders for the flavor—with some cacao powder, for instance, peanut butter becomes a chocolate peanut butter cup smoothie. We love Justin’s Nut Butters (the packs are especially great for making smoothies on the go), and Nuttzo, which contains seven types of nuts and seeds for a powerful blend.
