While there is no miracle smoothie or food that will magically kick-start weight loss, there are foods you can eat to boost your metabolism and help you feel full longer, like my weight loss protein smoothie.

This recipe uses whole food, plant-based ingredients that will give you the nutrients you need to conquer your day. I use this smoothie as a breakfast meal replacement smoothie for a few reasons.

It’s high in protein and healthy fat so I start the day full and satisfied. Cacao powder also gives this weight loss protein smoothie natural caffeine to wake me up, a bonus on busy mornings.

Chocolate Weight Loss Smoothie Ingredients

I’m using a slightly unique list of ingredients to whip up this deliciously filling smoothie. They are designed to wake up your metabolism and bring you natural energy to start your day.

ingredients in black text surrounded by white boxes for a weight loss protein smoothie including spinach, cacao, hemp hearts, almond butter, cayenne pepper, almond milk, cinnamon and banana.

Unlike most “weight loss smoothies” (filled with cheap proteins, artificial ingredients, taste chalky and leave you hungry) this one is the complete opposite. It truly tastes good and is good for you. Here’s what I’m blending:

Ingredient Swaps

If you read through the ingredient list and got caught on one or two ingredients then let’s fix it to make this smoothie work for you.

Almond butter can be swapped with the nut butter of your choice. Hemp hearts can be swapped with chia seeds or a plant-based protein powder.

Swap spinach with the leafy green of your choice. Can’t find cacao powder? Then use unsweetened cocoa powder. Use the plant-based milk of your choice. Each kind can offer different nutrients and even a bit more protein than the almond milk used in this recipe.

Chocolate Protein Smoothie Recipe

The beauty of a smoothie is that you can “eat and run.” I call it the world’s healthiest fast food because you can get a delicious, fast meal in five minutes! Blending this smoothie is super easy, yet I like to do it in two steps to ensure I always get the smoothest result.

  1. Blend together the almond milk and spinach until there are no leafy chunks left. If you need to stop the blender and scrape down the sides to achieve this then go for it.
  2. Add the remaining ingredients and blend again until smooth.

Pro Tips: Use a frozen banana to cool down this smoothie, or pour over ice after blending for a refreshingly cool smoothie. This will last up to 24 hours in the fridge so feel free to make two servings and save one for tomorrow.

Weight Loss Protein Smoothie FAQs

Are protein smoothies good for weight loss?

They can be, yet make sure your smoothies are full of some key things: healthy fat, protein and whole food ingredients. Ditch the weird powders and fancy supplements and stick to smoothies made with only real ingredients. I make sure every protein smoothie I drink has healthy fats, protein from plant-based sources and only natural sugar from fruits and vegetables.

Which protein shake is best for weight loss?

If you are using a protein shake as a meal replacement, or really anytime, make sure it has a good balance of carbs, fat and protein. Your body needs healthy fat to function fully and surprise, it actually helps you stay full longer! A good amount of protein in each meal will also help fill you up, and help process the natural carbs.

Is it OK to drink 2 protein shakes a day to lose weight?

If two smoothies a day works for you, go for it. Make sure you focus on a variety of ingredients in those drinks so you get the most nutrients you can. I like swapping up my leafy greens on a regular basis as well as using a wide variety of produce. This way my body gets all the vitamins, minerals and more that it needs to thrive.

  3. In your videos, you are not following your specific directions to blend the liquid with the greens first. Why is that?

    1. Hi Michele! It definitely depends on the blender, so it’s easier to recommend it when you don’t know what blenders everyone else is using.
