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!

    Awesome green juice recipe! I like how green tea was incorporated, always looking for ways to drink more. Even better that it is chilled, perfect for the hot winter while getting my daily dose of veggies and fruit. Been using this juice lately… https://bit.ly/2MGzPMr … feeling great so far. Thanks for your blog and keep up with the great work!

    Yep, yes I did! And you’re a totally rawesome rawkstar – incase you were wondering!! 😉

    Can you drink this smoothie for multiple days or should you limit to just 1 or 2? Also is the spinach amount packed or loose? Thank you.

  6. SGS Rawkstar Amanda

    August 3rd, 2018 at 1:57 pm

    Hi Roseanne,

    You can totally drink this smoothie multiple days. If you’re like me, when I like something, I have it over and over again. The only thing to take into consideration is rotating your leafy greens. So if you love making this recipe, just make sure you’re changing up what leafy green you’re using. Instead of spinach, maybe try swapping in romaine or kale.

    It would be helpful to list the total calories.

  10. SGS Rawkstar Amanda

    August 3rd, 2018 at 1:54 pm

    Hi C.S.

    Thank you so much for letting me know! We try not to focus on the numbers too much, and that’s why you often won’t find them on our recipes. We’ve found that when you focus on fueling your body with fresh fruits + leafy greens, it balances out.

    Of course, I know that information is very important to some people. Some great apps to use are MyFitnessPal and LoseIt.com to find that information easily.

    August 6th, 2018 at 7:00 pm

    Hi! How many calories are in this smoothie?

  12. SGS Rawkstar Amanda

    August 6th, 2018 at 8:05 pm

    Hey Caitlin,

    We personally don’t count calories, so we don’t include them in our recipes at this time. You’ll find that when you consume more nourishing whole fruits and veggies, you will not only feel full longer, but you’ll also have lessened cravings for high-calorie, nutritionally empty foods. So in the end it balances out. But we know many people would like to have calorie info. Three great resources for tracking calories are Self Nutrition Data, and the phone apps: My Fitness Pal and Lose It.

  14. SGS Rawkstar Amanda

    August 16th, 2018 at 12:40 pm

    Hey Kelley,

    I am sorry you are allergic to celery. No worries though because you can substitute it for bok choy or cucumber.

    Can’t wait for you to try it 🙂

  16. SGS Rawkstar Amanda

    Hey Starsha,

    Yes, you can use this as a meal replacement if you are wanting to apply it as a weight loss.

  18. SGS Rawkstar Amanda

    August 17th, 2018 at 1:50 pm

    Hey Karen,

    Oh bummer those are my two favorite ingredients for my smoothies. You can add some chia seeds to help your smoothie maintain that thickness and still keep you full longer.

    I’m trying to eat healthier burn fat and build some additional muscle. Added protein is key for me to do that. As I am working out to help support all that Would this smoothie and added protein also be good for what I’m trying to do

    I sure hope it works better than the first one taste. I will be peeling and taking out the membrane next time from all instead of just half. All I taste is bitter grape fruit. I love it by its self but I never eat the membrane either. Come on results…. let’s burn some fat.

  32. SGS Rawkstar Carissa

    November 1st, 2018 at 2:49 pm

    Hey Amber,

    Make this recipe work for you! If you need to peel and take out the membrane then that is totally fine. We want you to enjoy this recipe!

    Yay, for fat burning time!!!

    Hey Laila,

    No problem!

    A great substitute for avocado is banana.

  36. SGS Rawkstar Carissa

    Hey Bec,

    A great substitute for green tea is black tea.

    Hope that helps!

    Can not have grapefruit. Any substitute for that?

  38. SGS Rawkstar Carissa

    November 7th, 2018 at 1:07 pm

    Hey Sandy,

    There isn’t a substitute that has all the benefits of grapefruit but you can totally swap it out for any type of citrus fruit.

    Hope that helps!

    November 11th, 2018 at 6:01 pm

    Hey, it’s absolutely delicious. I just have two questions. It was too thick when I followed your instructions so instead of one cup of green tea I added two. Is that okay? Also should I drink one every morning or two? One in the morning and one in the evening? Thanks a lot for this recipe.

  40. SGS Rawkstar Carissa

    January 23rd, 2019 at 12:21 pm

    Hey Kamil,

    That is perfectly fine that you added in some extra tea to thin it out! Sometimes depending on what blender you have the consistency can be a little different. Also, we always encourage everyone to drink two smoothies a day if you are wanting to. I would suggest to not drink too late in the day since there is caffeine in this smoothie. That way you still get a good nights sleep =-)

    You can drink this smoothie at any time. However, since it will give you a boost of energy we suggest taking it in the morning or around lunch time 🙂
