Low-Calorie Banana Strawberry Smoothie

As a certified nutritionist with many protein-rich breakfast recipes on the record, I set out to create a low-calorie, high-protein smoothie that could power anyone through a busy morning. I chose the ingredients carefully, but after blending it for the first time, one question lingered: would this breakfast have that beloved banana strawberry taste?

Mission accomplished! It was delicious. Packed with nearly 30 g of protein and only 390 calories, this smoothie combines fruits, leafy greens, low-fat dairy, and complex carbs to keep you full and on track with your weight loss goals. Bonus points, you can take it with you on rushed mornings.

Let's start blending!

Equipment

To make this smoothie, you'll only need a blender.

Ingredients

To make this low-calorie, high-protein banana strawberry smoothie, you'll need the following ingredients:

  • 0.9 oz (25 g) rolled oats
  • 1.1 oz (30 g) baby spinach
  • 1 small (3.6 oz or 101 g) banana
  • 2.8 oz (80 g) strawberries
  • 7.1 oz (200 g) 2% Greek yogurt
  • 2.2 fl oz (62 ml) low-fat milk

Role of each ingredient

Oats provide complex carbs that deliver a steady flow of energy while helping keep hunger at bay.

Among the vegetables with the fewest calories, baby spinach adds plenty of vitamins, iron, and fiber — all without influencing the taste. A stealthy way to boost the smoothie's healthiness, isn't it?

The banana and the strawberries bring vitamins, minerals, and the smoothie's signature flavor.

Low-fat Greek yogurt and low-fat milk form the smoothie's creamy base and provide bone-strengthening calcium along with most of the protein in our recipe. Also, did you know that low-fat milk counts among the foods with the lowest calories?

Ingredient alternatives

If you're on a dairy-free or vegan diet, you can substitute Greek yogurt with plant-based yogurt and add some vegan protein powder if you need more protein. And instead of low-fat milk, you can use plant-based milk.

Instructions

Here are the step-by-step instructions for making our low-calorie banana strawberry smoothie.

1. Add dry ingredients
