Fat Burning Smoothie To Boost Your Metabolism

Make fat cry by adding this Fat Burning Smoothie into your daily routine and to ramp up the effects of your workout and help boost your metabolism! This recipe is part of our FREE 3-Part Fuel you Metabolism Workshop.

I ardently believe that what we put into our bodies matters. That means the food we eat, the beverages we drink, the supplements, vitamins, and medication we take, and the things we don’t eat, drink, or ingest.

All of those things either help or hinder us.

I fall in love with a plant-based diet when I lost the weight and gained energy without even trying. I was just drinking smoothies and eating meals that were rich in fresh fruits and vegetables, nuts and seeds. (meat, eggs and dairy are more of a condiment that go with my plant-powered meal). 

I wanted to share my fat burning smoothie recipe in here too— so you can see just how incredible a smoothie can be. But first…

The Balancing Act: Healthy Eating, Exercise, and a Little Indulgence Too!

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 host a quarterly cleanse, where I give you a structured meal plan to focus on eating the foods that will help us feel the best.

Learn more about my Plant-Based 7-Day Cleanse.

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.

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 exercising and building up muscle.

More muscle means more fat-burning capabilities. So when we’re talking about boosting up 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.

Foods for Burning Fat and Boosting the 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.

What does that mean? It means that they 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 along way!

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) protein bar can give you the energy you need to power through a workout or recover from one.

A Good Sweat + Proper Fuel = results

When we exercise (I’m including cardio, endurance running, weight lifting, and things like Cross Fit), we do burn calories, but if our muscles are in need of nutrition, they’ll go for the easiest source first… and that’s not necessarily going to be body fat. Give your body energy (i.e. high quality calories) to power it through a workout. The workout will in turn 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!

These 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
  • 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
  • Fatty fish like salmon, tuna, mackerel, and sardines – protein to help build muscles, anti-inflammatory omega-3 fatty acids that help the body burn fat for fuel
  • 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
  • Cinnamon – polyphenols (powerful antioxidants) boost the metabolism and help regulate blood sugar
  • Watermelon and tomatoes– rich in beta-carotene (form of vitamin A) and lycopene (good for the heart and help discourage fat storage), hydrating, high in fiber
  • 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


Fat Burning Smoothie Recipe

This weight loss smoothie is a little more hardcore than our other recipes, but we believe it will help you see results more quickly when combined with an exercise program. We hope you give it a shot and love the results as much as we do. Happy blending!

    Pleasantly surprised. Delicious! I had to do a couple of modifications because I didn’t have all of the ingredients. I replace spinach with kale and collard greens, a tangerine but of grapefruit oh, and I didn’t have any mint. But it came out great! Diet plan to eat a meal with it this morning because I felt the need to chew however, I was quite full with one serving and some water. Instead I’m making a big lunch with this afternoon and plan to have another smoothie this evening. Thank you so much for sharing this! And thank you everyone else for your input and suggestions because that truly made a difference in me trying out this drink. Oh and I’ve never had avocado in a smoothie before, but I love Avocado. It gave it a nice creamy consistency without interrupting the other flavors. And the MS in my user name stands for Multiple sclerosis.

    Even though this smoothie isn’t as sweet as most other SGS recipes, it’s thoroughly satisfying and very delicious. I love any smoothie that combines fruits with veggies. I made it with kale and added chia seeds. This could easily become part of my regular rotation.

    Hi Mireille,

    SO glad that you enjoyed this recipe so much! The kale and chia seeds sound like a great addition to this recipe 🙂

    Hi! Love this smoothie, i feel like Wonder-Woman after having this for breakfast! 🙂 I always have at weekends but dont have time during week to make it fresh each morning before work – is it suitable for freezing? Was thinking I could make a batch at the weekend and freeze portions to have during the working week.

  5. SGS Rawkstar Carissa

    March 27th, 2019 at 2:46 pm

    Yay!!! We love that wonder woman feeling!! 🙂

    You can totally freeze your smoothie, just make sure to put it back in the fridge in enough time for it to thaw out. Also our smoothies can stay in the fridge for up to two days. Just add in some lemon juice to keep the color, give it a little shake and you are good to go!

    I have meds for high blood pressure and was told not to eat grapefruit until 2 hours had passed from taking my meds to eat grapefruit.

    Hey Betty,

    Make sure to check with your doctor so that you are doing what is best for your body.

    Thanks for the recipe! It was delicious!
    Is there anything I could try in place of grapefruit though? I can’t have any because of a blood thinner I’m on. Wonder if orange would work?

  9. SGS Rawkstar Carissa

    April 10th, 2019 at 1:30 pm

    Hey Hailey,

    There really isn’t a substitute for grapefruit as far as benefits but for taste you can totally swap it with any citrus fruit. So an orange would be great!

    I was wondering if the mint is more for flavor or could it be omitted without taking away any of the health benefits of the smoothie? I love the recipe but totally forgot mint at the store and was wondering if I should make an extra stop for it. Thank you so much!

  11. SGS Rawkstar Carissa

    June 10th, 2019 at 3:34 pm

    Hey Jacqueline,

    Mint is actually a key ingredient in this recipe. It really helps with the detoxifying process. It grabs onto the heavy metals and draws out all those nasty toxins. So if you can add it I definitely would!

    Curious., Would tumeric be an added benefit? (Tumeric loves cayenne)

    I found that it was bitter so added 2 bananas to it. it helped some. what can I add so that it is not so bitter

  14. SGS Rawkstar Carissa

    July 22nd, 2019 at 11:42 am

    Hey Christina,

    Our favorite natural sweeteners are dates or adding in some honey. So feel free to add in some of that to help make it tastier for you 🙂

    I do rate this recipe 5 stars!! Excellent flavors. Wonderful for digestion. I am wondering how crucial the green tea is vs. leaving it out. I just don’t do caffeine. I understand there can be health benefits from green tea. Is it necessary to achieve results? Does not including it ruin the synergy of this drink? On another comment you stated adding kale or chia seeds was a good idea. Does adding other ingredients change the synergy of this drink?
    Thanks for all you do.


    August 13th, 2019 at 5:08 pm

    Excellent…. I highly recommend this smoothie. So delish!

    This smoothie really does get your energy levels revved up and curbs your appetite. I’ve always loved grapefruit so this is perfect for me.

    Can I prep and freeze into packs for quick morning mixing?

  20. SGS Rawkstar Carissa

    September 9th, 2019 at 9:14 am

    Yes you can totally prep and store in the fridge or freezer! This could stay in the refrigerator up to 3 days. When you are ready to drink just give it a shake and you are good to go!

    I am about to turn 50 and for the 1st time in my life I have a weight problem. I’m also a disabled heart patient but I’m not dead and continue to work 2 days per week to keep going. I need your help with these smoothies. I love the idea of smoothies because they fill you up. Makes you feel like you just ate a meal! When really you just drank some healthy, good for you and will help you to lose weight 🙂 Please help me and give me advise. I don’t want to be heavy. It will eventually complicate my heart problems and I’m managed to not let it affect who I am for 10 years now! But the extra weigh that has come on in the past 6 months is making it much harder to stay positive. Thank you

    Hey Laurie,

    This my second week of making this recipe. I make this smoothie for 2. I looked at the video again but it does not match the recipe. She uses 1 cup pineapple, 1 celery stalk, 1/4 of an avocado. The recipe for one drink shows for one has 2 cups pineapple, 2 celery stalks and half of an avocado. I like the drink but does it matter how you mix it.

  25. SGS Rawkstar Carissa

    October 4th, 2019 at 10:22 am

    Thank you for letting us know the recipe is incorrect. The recipe in the video is correct for one serving. The recipe on the website is serving for 2.

    Hope that helps!

    Very tasty but a smoothie? A whole bag of spinach? Not much liquid. I almost had to cut mine with a knife and that was halving the amounts as I didn’t have a vat to blend mine in lol

  27. SGS Rawkstar Carissa

    October 14th, 2019 at 9:45 am

    Hey Debbie,

    It sounds like you are really packing in the spinach which is great if that is what you prefer but for me personally I wouldn’t be able to handle that =P We like to add in loosely packed spinach that way it is not too thick.

    Hope that helps!
