There are so many reasons why I think you will love this smoothie as much as me.

Some of the main reasons include:

  2. High in Protein: With the inclusion of Greek yogurt and peanut butter, this smoothie is high in protein. A serving of this smoothie contains 11g of protein.
  3. Supports Healthy Weight Loss: The high protein and fiber content, particularly from flaxseeds, can help in controlling appetite and reducing snacking, supporting healthy weight loss.

  5. Heart-Healthy: Flaxseeds are rich in omega-3 fatty acids, which are known to support heart health by lowering triglyceride levels and improving cholesterol profiles. 
  6. Digestive Health: The fibers from the banana, and flaxseeds help to promote healthy digestion and prevent constipation.

Smoothie Variations & Recipe Notes:

Weight Loss Banana Peanut Butter Smoothie

You can easily customize this smoothie recipe should you want to.

Below are some ideas that I have personally tested and loved:

  • No Banana: Use mango or pineapple instead of bananas. 
  • Vegan: If you are vegan, use vegan-friendly yogurt instead of dairy yogurt. Alternatively, use 1/4 avocado. 
  • Protein Boost: For more protein, use low-fat dairy milk instead of almond milk. This is only applicable to people who are not dairy-free. 
  • Greens: Throw a handful of greens such as baby spinach or kale for extra nutrients.
  • The Nut Butter: You can swap the peanut butter for almond or cashew butter.


Blender Type Suitability
Nutribullet 600
Vitamix Blender Propel 510
BlendJet 4000mAh
Ninja Blender BL610
Oster 6640 Blender
Hamilton Beach 58148A Blender
AMZChef Blender 1800 W
Wamife Blender

Since the recipe is made using no frozen ingredients, blending isn’t an issue at all, especially for lower-speed blenders.

However, if you are making more than 1 serving, I recommend that you use a higher-capacity blender. Avoid the Nutribullet 600 and BlendJet 4000mAh.
