Weight Loss Smoothies

I fell in love with a plant-based diet when I lost the weight and gained tons of energy without really even trying. Just drinking smoothies and eating meals that were rich in fresh fruits and vegetables, nuts and seeds did the trick! I began seeing meat, eggs and dairy as more of a condiment that goes with my plant-powered meal.

To help with the results, I started focusing on blending ingredients that are scientifically proven to burn fat and boost the metabolism, which lead to weight loss. Now, let’s dive into this fat burning smoothie recipe so you can see just how tasty and simple weight loss can be. But first…

Why smoothies help you lose weight

For most of us, there’s a balance between the good things and the not-so-good things. (I’m talking to you, French fries with my veggie burger.) My point is, it’s hard to always eat healthy. Which is why I like to do the Fresh Start seasonal cleanse using green smoothies (like this one!) as my breakfast for 21 days. It gets me back on track and makes sure I drink the best smoothies for weight loss and my overall health.

There are special occasions when we want to indulge, it’s hard to eat healthy all the time when traveling. You know the drill. We do our best. And I don’t believe in punishing ourselves for enjoying a treat now and then.

Build Muscle to Burn Fat

What I’m a big proponent of is eating healthy as much as possible and participating in a regular exercise routine. That looks different for all of us with our varied interests, schedules, time constraints, and lifestyles. There’s nothing that will help boost your metabolism more than doing exercises that build muscle.

More muscle means more fat-burning capabilities.

For me, that’s running 3-5 times a week and lifting weights 3 times a week. When it comes to boosting your metabolism, exercise goes hand in hand with healthy eating. Certain foods have fat-burning and metabolism-boosting abilities and adding them into your diet can help magnify weight-loss efforts. I’m a huge fan of smoothies, especially when I can use natural ingredients to transform it into a weight loss smoothie.

Give your body energy (i.e. high quality calories) to power it through a workout. The workout will help build more muscle, which burns more calories (i.e. fat) the rest of the time. See how nicely that works? It’s a beautiful thing!

Fat Burning Foods to Boost Metabolism

Our body needs proper fuel to keep up with the demands of daily activities. It’s important that the calories we consume, especially if we’re trying to lose weight, gain muscle, or just improve our performance, are quality calories.

A protein bar may be high in calories and full of nutrition, but it won’t fill you up in the same way a plate of salmon, brown rice, and steamed veggies will. But a high-quality (preferably homemade) vegan protein bar can give you the energy you need to power through a workout or recover from one.

What does that mean? It means that recipes need to tick off several boxes: healthy fats, protein, complex carbs, vitamins and minerals, and/or a combination of all of the above. A fat burning smoothie, which I’ll show you how to make below will take you a long way!

17 Foods that Burn Fat Naturally

Here are some foods you can blend into a weight loss smoothie if you’re trying to boost your metabolism and burn fat:

  • Nuts – whole, preferably raw and unblanched (almonds, walnuts, pecans); good fats and protein; almonds contain L-arginine (an amino acid) that when used pre-workout can help the body burn more fat
  • Eggs – high in protein which helps boost metabolism; the body digests the protein and uses the fat and calories for fuel. Yes, some people truly do blend raw eggs in their smoothies— yet I never have!
  • Berries – low in sugar but still sweet, high in fiber, high in antioxidants; helps burn fat; can help to improve blood flow
  • Apple cider vinegar – the acetic acid in ACV helps with blood sugar levels
  • Grapefruit –high in phytochemicals that stimulate the production of the hormone adiponectin which helps the body break down fat
  • Green and white tea – caffeine in tea gives a natural boost of energy’ antioxidants in tea may help accelerate fat-burning by aiding the liver in converting fat to energy
  • Chili peppers – capsaicin, the compound found in pepper aids the body in converting food to energy and abdominal fat loss; also works as a natural appetite suppressant
  • Spinach + other leafy greens – chock full of vitamins and minerals and fiber
  • Whole grains – like oats and brown rice; high fiber; slow-burning to keep you fuller, for longer and fuel the body
  • Coconut oil and olive oil – healthy fats that help you feel satisfied when they are consumed; coconut oil is easily digested for quick energy
  • Avocado – healthy fats, fiber, and vitamins, particularly B6 which counteracts cortisol, a stress hormone that contributes to weight gain via belly fat stores
  • Flaxseed – high in omega-3 fatty acids – check out our organic, clean, specially formulated Protein Smoothie Boost with flaxseed
  • Cinnamon – polyphenols (powerful antioxidants) boost the metabolism and help regulate blood sugar
  • Pears and apples – high in fiber plus contains pectin; helps keep you fuller for longer and naturally sweet
  • Grapes – high water and fiber content
  • Celery – very high fiber, uses more energy to digest than it provides (i.e. negative calories)
  • Dark chocolate – 70%+ cacao content is the important part; cacao contains high concentrations of polyphenols that push the body to burn fat

  2. Emma says:

    Hi I have started drinking this I’m on day 3 , just wandering if this amount is to be drunk in one or two servings ? I’ve been drinking it all for breakfast…

    Many Thanks

    • Simple Green Smoothies says:

      Hey there Emma – great question! The recipe is 1 – 16 oz.serving, which we consume all at once. So you’re good! Keep up the blending awesomeness and keep us posted on how things go for you!

  3. Victoria says:

    Am happy for the recipe.

  4. Suzanne says:

    Hi there! I need to avoid caffeine. What could I sub for the tea? Thanks in advance!

    • Simple Green Smoothies says:

      Hey Suzanne – fantastic question! To avoid caffeine, you could swap in water for the tea. Also, there are caffeine free green tea bags available at most grocery stores that you could try as well. Happy blending!

  5. Joy says:

    I made the smoothie and it turned out really great! The taste was delicious and creamy! It kept me full for several hours! I’ll definitely make it a part of my weight loss program! Thanks again!

    • Simple Green Smoothies says:

      Isn’t it awesome when what’s good for us tastes good too! Way to rawk this Fat Burning Smoothie, Joy!

  6. Marlene Zipperian Kaiser says:

    Didn’t use your recipe, plan to use it next. I had some tomatoes that were overripe so I made my first green smoothie out of them. I used 2 tomatoes, a handful of chopped spinach, a banana, 1/2 cup of yogurt, 1 orange, juice of 2 lemons and a scoop of whey, 1//2 tsp of ginger plus about 1/2 cup of water. I was surprised by how good it was. It didn’t taste anything like the veggies tastes by themselves. I was just using up what I had in the house. I have been using lots of fruit with water and whey for a while but decided to try the green smoothie when I found a bag of chopped frozen greens I assumed were spinach at a harvest give away that I have been getting my fruit from. Overripe fruit makes wonderful smoothies all by themselves. I freeze my bananas and make them into ice cream in my blender to have for dessert. They are so good. Taste like real ice cream. I get this overripe fruit and veggies all the time and puree them then freeze the puree for my smoothies, but now I will add some of the nuts I get an abundance of from the give away place. I even get dried cherries, and I guess they could be soaked to reconstitute them and use them also. I have a lot of them. The reason I wrote this was your list of items we could use really impressed. I wonder if I could soak and cook beans and add them to the smoothies also. I have lots and lots of dried beans of all kinds. Will that work?

    • Simple Green Smoothies says:

      Thanks so much for sharing Marlene! We typically save beans for including in recipes like our Thai Lettuce Wraps, yet if you give some beans a blend def come back and let us know what you thought!

  7. Yessi says:

    Hello what can I replace the avocado with allergic and soy . Ty

    • Simple Green Smoothies says:

      Hi Yessi! In place of avocado, you could use a nut butter of your choice or a combo of banana + MCT oil. Banana brings the creaminess and MCT oil adds the healthy fat you’d be missing without the avocado.

  8. MJ Henderson says:

    What does 1/4 avocado equal in cups of frozen avocado chunks? Thanks!

    • Simple Green Smoothies says:

      Depending on the size of your avocado chunks, it would likely be 2-3 pieces.

  9. Erica says:

    Can you substitute the green tea with Matcha??

    • Simple Green Smoothies says:

      Totally Erica! Great idea. Matcha is the powdered version of the whole green tea leaf, so it would work well here. Plus you’d get additional health benefits by consuming the whole leaf vs. what you find in the tea.

  10. Carlos says:

    Needed something to have a little sweetness to this smoothie – not great tasting – probably needs crushed ice to make it more palatable. Maybe adding berries and some other sweeter fruit might help. I would like to lose weight and enjoy the health benefit of the smoothie but his recipe is not very palatable.

    • Simple Green Smoothies says:

      To up the sweetness factor, try adding a bit more banana or a date or two. Keep in mind that this will increase both the calories and natural sugars.

  11. Levi says:

    Thank you for your clip about making smoothies. I was surprised you did not mention strawberries. They’re both, soluble & insoluble fibre as well as body fat burners and not to forget, they’re gorgeously delicious. also, blueberries were strangely absent from your menu

    • Simple Green Smoothies says:

      We’re def fans of strawberries and blueberries here at SGS! So many good ones, we couldn’t include them all. Thanks for helping those two shine Levi!

  12. Elisa Watson says:

    All I can say is “very well done “ GREAT And GOING TO TRY IT OUT ASAP
    THANK YOU ❗️

  13. Christel says:

    this seems really good and i need to loose a lot more weight

  14. Michelle says:

    I like this smoothie and the purpose of it. Could you add an apple or prunes to the smoothie or substitute the pineapples for one of these to get the benefit of the fiber or would it change the purpose of the smoothie if you did add them? Thank you in advance for responding!!!

    • Simple Green Smoothies says:

      We love pineapple in this smoothie for it’s water and fiber content, so you’re idea of prune is great! Since apple or prune wouldn’t be as high in water content, you may need additional liquid when blending. Let us know what you try and what you think!

  15. Sherry Perdue says:

    I like this smoothie and have used it as a snack as well as added protien powder to make it a meal. I have a tendency to fall into a very low calorie intake trap on occasion and this smoothie has helped me keep my cal intake closer to where it should be without being heavy I my system.
    I am however wondering what can be substituted for the pineapple. I have tried doing half cup frozen blueberries with half cup mango. Is this okay or is there something about the pineapple that makes this smoothie work better?

    • Simple Green Smoothies says:

      Great question Sherry! We like pineapple in this smoothie because of it’s higher fiber and water content. That’s what really helps us ‘get going’ with weight loss. However, some of our fav swaps for pineapple are oranges, mangoes or peaches. So you’re idea of swapping in mango is right on the money!

  16. miranda says:

    this look”s really good im going to try this

  17. Brenda S. says:

    I am desperate to loose weight, I like the simplicity of this recipe and it makes sense. The taste is not the best, but I can do it to loose weight. I have found that the older I get the harder it is to loose weight, I am 61 now. We adopted a year old puppy for company on walks. But I have no energy, I was hoping the combination of the dog and this smoothie get me moving.

    • Brenda S. says:

      Update from 5/6/2021:
      I have lost 9lbs. This is a very easy recipe and I make the one for the next day all ingredients in a mason jar for blending the next morning. It is a great way for me to lose weight, I am pleased with the results still looking for the energy boost to do some walking.

    • Simple Green Smoothies says:

      Woo hoo Brenda!!!! We’re cheering you on here at SGS! 🙂

  18. Eden says:

    What fruit can I substitute with grapefruit ? Thanks

    • Simple Green Smoothies says:

      Whether it’s an aversion to grapefruit or a med interaction you’re avoiding – you’re def not alone in needing to swap out the grapefruit Eden! You can use orange, tangerine or clementine instead. Happy blending!

  19. oj says:

    Can i replace the avocado with something else.

    • Simple Green Smoothies says:

      We love it when everyone gives new things a try, OJ – so if the avocado isn’t an allergy, you might give it a blend! We promise you won’t even know it’s in there! However, if it is an allergy or you just can’t stomach it, you can totally swap it out. Try MCT oil + flaxseed or adding in some chia seeds to help replace the good fat and fiber we get from avocado.

  20. Kay says:

    Is there a replacement that can be used for the mint leaves?

    • Simple Green Smoothies says:

      Mint can be tricky to replace, yet the closest we’ve found is it’s cousin basil. If it’s just that peppermint isn’t your jam, you could try one of many other varieties of mint, like spearmint, apple mint or pineapple mint (which would be totally fab in this recipe!). Let us know what you blend and how you liked it!

  21. Holly says:

    I can’t remember if I’ve already commented on this recipe…but I had to again, just to be sure! I LOVE this smoothie. What’s funny, though, is I can’t stand grapefruit, and I usually only like celery in soups! But my body was craving not-so-sweet smoothies, so I did a search through the SGS smoothies and came up with this one (admittedly, the “fat burning” part caught my eye too :). I decided to take the plunge and check it out, and it has actually become one of my favorites, which is still a shock to me. It’s light but filling, and I love that you can adjust the sweet-tart ratio by adjusting the grapefruit and pineapple. This one is going in regular rotation.

    • Simple Green Smoothies says:

      That is such an awesome discovery Holly! We love, love, love how green smoothies can help us get those foods in that we otherwise wouldn’t eat.

  22. Steph says:

    Hi is there any replacement I could use for the avocado?

  23. emily stone says:

    i cant eat grapefruit because of a medicine i take. can you recommend a substitute that would be just as good?

    • Simple Green Smoothies says:

      We love oranges, tangerines or clementines when grapefruit isn’t an option. 🙂

  24. Destiny phillips says:

    It’s a bit bitter but it’s still easy to consume. I’m enjoying the challenge since I’m trying to shed 20lbs .

    • Simple Green Smoothies says:

      Hi Destiny! You can try adding a touch more pineapple to this to adjust the taste if the grapefruit is too strong. So glad you’re rawkin some more plants using smoothies. You’ve got this!!!

  25. Shalonda Roberts says:

    I really do need to lose weight because I had a right hip replacement so I can’t put that much weight on my hip and also trying to lose belly fat

    • Simple Green Smoothies says:

      Oh wow! Hope you heal well and that this smoothie is helpful to you!

  26. Abby says:

    Will this help me burn my fat and loose the weight whilst I am doing exercises in the week . I run pretty much every day or when I can.

    • Simple Green Smoothies says:

      This smoothie, combined with the awesome running you’re doing, should def help with weight loss. Remember, losing weight is different for every body though. Usually we see the best results over time.

  27. Ju says:

    Hi, could you confirm how much of mint needed please.It says 2 Tbsp cup…but i guess you can’t measure mint leaves with spoon I am definitely trying this smoothie.Thank you

    • Simple Green Smoothies says:

      Oooh – thanks for catching that Ju! We’ve corrected it to read ‘2 Tbsp’, which is equal to about 10-12 mint leaves. Happy blending! 🙂
