Why You Will Love This 50 Calorie Smoothie

50 Calorie Smoothie

One of the main benefits of this low calorie berry smoothie is its precise calorie count per serving.

When I am dieting and trying to lose weight, I do that by counting calories.

Sometimes I fancy a drink with my meal, but cannot have more than 50-100 calories.

That’s when I love to make this smoothie.

Other reasons include:

  1. Refreshing Taste: The natural sweetness and tartness of raspberries combined with the freshness of spinach make for a delightfully refreshing drink, perfect for hot days or as a palate cleanser.
  2. Perfect Diet Companion: With just 50 calories per serving, it’s an excellent choice for anyone monitoring their calorie intake or following a weight loss plan.
  3. Quick and Effortless Preparation: This smoothie requires minimal ingredients and prep time, making it an ideal choice for busy mornings or a quick, no-fuss snack anytime during the day.
  4. Hydration Boost: Made with a base of water and ice, it’s an excellent way to stay hydrated, offering a more exciting alternative to plain water.
