This weight loss smoothie recipe will help your boost your metabolism using plant-based whole foods.

The #1 question I get at Simple Green Smoothies is…

Will a smoothie help me lose weight?

There are TONS of smoothies and shakes out there claiming to do this, but forget the labels and ads… and think about what’s gonna work for YOU.

When it comes to a weight loss smoothie, it’s gotta hit 3 things for me to call it a winner:

  1. It must be affordable to continue doing this every single day.
  2. It has to deliver the results it promises: boost my metabolism, keep me full and not hangry, actually nourish my body, etc).
  3. It’s gotta taste great (and not be loaded with tons of sugars, artificial flavors or “fake sugars” to trick your tastebuds and ravage your cravings). I want to crave this day after day and feel better when I have it!

The recipe I’m sharing here helped me lose 7 pounds when I was a young exhausted mom of 2 under 4…with no energy and a few post baby (by a few generous years) extra pounds I needed to lose. They say “you’ve gotta exercise to lose the weight”, but when you’re too tired to do that— you’ve gotta try something else. And this is the secret sauce to jump start my energy levels and my weight loss journey.

Today, I want to share a weight loss smoothie that I’ve been using as a breakfast meal replacement smoothie. And yes, it’s a green smoothie because these are the BEST way I’ve found to lose weight naturally AND feel great while doing it.

Unlike most “weight loss smoothies” (which require expensive powders, artificial ingredients and taste chalky and nasty… and leave you hungry) this one is the complete opposite. It truly tastes good and is good for you. You can drink they smoothie every morning for breakfast, which is a great way to set a healthy routine for your day.

I’ve also had this for lunch as a meal replacement smoothie too. Some days I just don’t have time to make lunch and a quick smoothie is the way to go. Other days, I’ll sip this down while doing dishes, driving the kids to practice, running errands, after a long trail run, you name it— the beauty of a smoothie is you can “eat and run.”

If leaning up if your goal, the ingredients you use in your smoothie can work against you… or for you. I’m gonna break down the ones I used in this smoothie to help you see WHY I used them to hit my summer body goals: turn my fat into muscle and have the energy to workout.

Spinach: Full of phytonutrients and fiber to minimize any blood sugar spikes from the natural sugars in the smoothie. 

Almond milk: Contains a little bit of protein and promotes a creamy smoothie base. 

Banana: Adds a little natural sweetness to give you an energy boost.

Almond butter: Curbs your appetite and helps your digestive system

Cacao powder: Boosts your energy levels and metabolism

Hemp hearts: Have twice as much protein as chia seeds.

Cinnamon: helps regulate your blood glucose levels. The last thing you want from your smoothie is a sugar rush, which can give you quick energy and then have you crash real hard. 

Cayenne pepper: Helps curb your appetite and boost you metabolism naturally.

I went from exhausted mama to running across the Grand Canyon, riding & hiking to the top of the tallest waterfall in North America with my kids. How? I fell in love with the smoothies and plant-based meals you can find on my blog.

  1. Hi, I have a thyroid condition and am often told to avoid spinach and other goitrogens as they can interfere with the production of thyroid hornomes. I know that cooking goitrogens removes the issue but would this work as well in this type of smoothie or can you suggest an alternative? I would feel uneasy about eating them every day. Thank you

    1. Hey Amanda – you can swap greens any time. We use spinach quite a bit just because it’s mild and easier for everyone to get used to when first rawkin green smoothies. Check out our article Ultimate Guide to Leafy Greens for great swap ideas for your greens. And def check-in with your doc to be sure the ingredients are best for your thyroid. 🙂

  2. Hi! I just made this for the first time. It’s good! I prefer it colder, so think I will add ice next time. I had it for dinner. I don’t normally have smoothies for dinner, but we had lunch out and I wanted to do something lighter. Is this smoothie better for you in the morning? I just did your 7 day cleanse and have been checking out your other smoothie recipes. I am considering doing this recipe and the fat burning smoothie, 2 smoothies a day for weight loss – 1 for B, 1 for L. Is that a good plan? Does it matter which one I do for which? Thank you!

    1. Hey Kim! You can def add ice but you could also freeze your bananas and spinach and that would make your smoothie creamy and cold. 🙂

      Because this smoothie contains cayenne pepper, which gives your metabolism a kick, I think I’d drink it in the morning. But, you really can drink it any time during the day. Many folks drink a smoothie for breakfast as well as one for lunch, that’s actually what we do during our 7-day summer and winter reset cleanses. And it doesn’t matter which smoothies you drink, as long as you’re drinking one! We have so many, it really depends on what you’re looking to get out of your smoothie. We have smoothies that are anti-inflammatory, cleansing, and packed with antioxidants. Take a look around our recipe page for those and more.

      Hope you enjoyed our 7-day challenge. We’ll be doing a 10-day smoothie challenge starting on June 15 and our summer 7-day reset starts July 6. You should join us for those!

  3. I don’t have almond butter can i substitute with something else? I have chia seeds and not the hemp hearts so I will be try that out. For the meantime that you reply I will try without the almond butter. Hope to get a response from you soon thank you.

  4. I stumbled across this recipe and I decided to give it a try but my gosh the cinnamon and cayenne was too much for me. I may have been a little heavy handed because it’s spicy. I don’t taste any sweetness at all but I’m going to chug it anyway.

    1. Hey Lakia! Just the smallest amounts of cinnamon and (especially) cayenne will work great in this smoothie! Def give it another try with less of those, and I think you’ll like it more. Also, using a banana with brown spots will give it a little bit more sweetness. 🙂

  5. Hi,

    Is is possible to make this smoothie without banana? Does the smoothie still have the same benefits or do I have to substitute it with something else?

    1. Hey Stephanie! If you prefer to not use banana in your smoothie, you could use avocado (for the creaminess) and a few medjool dates (for the sweetness). You could also use mango (both creamy + sweet) but that option will contain more natural sugars. 🙂

  6. I just made this smoothie today for the first time and the taste of cinnamon was a bit too much. I noticed that you say 1 Tsp of cinnamon but in the video u used 1/4 Tsp. Also i doubled the recipe so i can drink one the following morning, i dont know if me doubling the recipe just gave me a strong cinnamon flavor.

    1. Hi Mike! This recipe does call for 1 tsp. of cinnamon but if that’s too strong for you, def try 1/4 or 1/2 tsp. and see if you like that better. I do think that if you made the smoothie ahead of time and put it in the fridge, that could be the reason. The longer a spice like cinnamon sits in a green smoothie, the stronger the cinnamon taste is going to be. Try making the smoothie ahead of time with all the ingredients except the cinnamon and then add that right before you drink it and see if that makes a difference.

    1. Isn’t this one good?! And you feel like you’re eating dessert! 🙂

    The first time I made this, it tasted awful! I don’t know what I did wrong. I now have it every morning and love it.
    Who knew how delicious almond butter is compared to peanut butter! Loving this recipe!

    1. I agree, Joy. Once I tasted almond butter, I never wanted to go back to peanut butter!

    I tried this today, it’s not as delicious as it sounds, I like the idea of the warm almond milk..I’m also hoping for the metabolism boost so I’m going to give it another try tomorrow. Thank you for the recipe!

  9. 5 stars
    This is in my regular rotation now. I am going to prep a lot of bags. It has a lot of my favorites and who doesn’t like chocolate and bananas together?

  10. Thank you so much for posting this recipe! This sounds super easy and doable. Im wondering what the serving size is?

    1. This recipe yields 2 cups or about 16 ounces, which is one serving of smoothie deliciousness!

    2. We don’t have calories listed for this one but you could use something like My Fitness Pal to help you figure that out. 🙂

  11. Right now, November in I prefer warm smoothies. I don’t feel like cold when its cold outside. So I use warm almond milk and let my vitamix run a little longer. Yummy and warm

    1. That sounds so delicious! I am the same way I love drinking warm things during the cold months 🙂

  12. Would it be ok to swap out the hemp hearts for flaxseeds? I have never used hemp hearts before, what is the difference, benefit -wise, between the two?

    1. Hey Janice,

      You can totally swap the seeds if you would prefer that. The difference is flaxseeds have a lot more omega 3 fatty acid in them then hemp hearts and hemp hearts have a lot more protein in them then flaxseeds.

      Hope that helps!

    1. Hey Lacey,

      If you prefer the chocolate protein powder then you can definitely add that as a substitute!!

    Try as I might, I just do not love cinnamon. I’ve made this smoothie and it’s ok but I know I’d really enjoy it without the cinnamon. Any recommendations for a substitute with similar benefits?

    1. Hey Joanna,

      You can swap the cinnamon for nutmeg if you prefer that!
