A green protein smoothie can be a nutritious choice when you need something quick and portable. This smoothie has nutrients you need for satiety like protein and fiber. It’s low in sugar, and calorie-controlled to help you stay on track with your weight loss goals. It’s a way to start your day with vegetables, protein, fruit, and healthy fats. Just add the ingredients to a blender.

Variations and Serving Suggestions

  • For fiber and omega-3 fats, add 1 tablespoon of chia seeds or ground flaxseeds.
  • For warm spices, add a dash of cinnamon, nutmeg, or pumpkin pie spice.
  • For extra flavor and antioxidants, add ¼-½ cup of berries, mango chunks, or peach slices.
  • For a thicker smoothie, make sure your banana is frozen. You can also freeze your spinach ahead of time to reduce the need for ice cubes.
  • For a plant-based (vegan) protein source, swap whey protein for a plant-based protein powder like soy, pea, or brown rice.
  • For more nutrients and volume without many calories, add ¼ cup of frozen cauliflower florets or frozen sugar snap peas.
