This weight loss shake recipe uses whole food, plant-based ingredients that will give you the nutrients you need to conquer your day. I use this recipe as an alternative to my vanilla protein shake when I’m craving chocolate smoothies. It’s high in protein and healthy fat, so I start the day full and satisfied. Cacao powder also gives this weight loss protein shake natural caffeine to wake me up, a bonus on busy mornings.

Chocolate Weight Loss Shake Ingredients

Unlike most “weight loss shakes”—which are often filled with cheap proteins, artificial ingredients, and leave you with a chalky taste and hunger—this one is the complete opposite. Together, these ingredients create a chocolate weight loss shake that’s rich, satisfying, and balanced—without relying on added sugars or fillers.

  • Almond milk: Rich in vitamin E and magnesium, this plant-based milk is low in sugars and carbs. Its mild, slightly nutty flavor pairs perfectly with the other ingredients. You can make your own almond milk or buy one of my recommended almond milk brands.
  • Spinach: This leafy green vegetable is a staple in a lot of my shakes since spinach contains fiber, protein, iron, calcium and so much more. Bonus—you don’t even know it’s there!
  • Frozen cauliflower: Thickens the shake and adds nutrients without changing the chocolate flavor.
  • Frozen banana: Just enough natural sweetness and creaminess without spiking sugar.
  • Cacao powder: Deep chocolate flavor plus antioxidants, making this feel like a treat.
  • Almond butter: Full of healthy fat and adds a lovely nutty flavor to this shake.
  • Cinnamon: Adds warmth and may help support balanced blood sugar.
  • Cayenne pepper: A small pinch brings gentle heat and supports metabolism.
  • Protein powder: The key to turning this into a filling, protein-rich shake.

How to Make a Weight Loss Shake

The beauty of a shake 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 chocolate weight loss shake is super easy, yet I like to do it in two steps to ensure I always get the smoothest result.

  1. Blend the almond milk and spinach together 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 banana, cocoa powder, almond butter, cinnamon, hemp hearts, and cayenne pepper. Then blend again until smooth.

How to chill a Shake

Freeze banana to cool down this chocolate weight loss shake, or pour over ice after blending for a refreshingly cool drink. This will last up to 24 hours in the fridge, so feel free to make two servings and save one for tomorrow.

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 weight loss protein shake work for you.

  • Almond butter can be swapped with the nut butter of your choice.
  • Swap spinach with your preferred leafy green vegetables.
  • Can’t find cacao powder? Then use unsweetened cocoa powder.
  • Don’t like almond milk? Use the non-dairy milk of your choice. Each kind can offer different nutrients and even a bit more protein than the almond milk used in this protein shake recipe for weight loss.

More Weight Loss Shake Recipes

If you’re loving this weight loss shake, there are plenty more protein-packed smoothies to keep things fresh and satisfying. For a lighter, refreshing sip, the banana chocolate protein shake blends creamy and fruity flavors, while the salted caramel protein shake tastes like a treat yet delivers staying power with healthy fats and protein. The meal replacement smoothie is a balanced option when you need something filling that can stand in for a meal.

Common Questions

Are protein shakes good for weight loss?

They can be, but make sure your protein shake recipes are full of some key things: healthy fat, protein, and whole food ingredients. Ditch the weird powders and fancy supplements and stick to healthy weight loss shakes made with only real ingredients. I make sure every protein shake 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 shakes 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.

    1. Barbara, so glad you enjoyed the shake! Thanks for the review!

  1. What a treat, and good for us too! I have been making your Chocolate Peanut Butter Smoothie for years. This healthier twist of chocolate and nut butter was a delicious surprise! We could not taste the cayenne and my husband said I could make it again! More greens = win!

    1. What a win, when the family likes a healthy shake. This recipe is a favorite and I’m glad your family enjoys it too.

  2. 5 stars

  3. Hi my name is Cecilia and today is my Birthday A Wonderful age of 65 . I am diabetic, congestive heart failure, and a few other ailments. I am new to smoothies.

    1. Just love hearing this. Welcome to the community and to joining us on this journey of health, Cecilia.

  4. 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.
