I started making weight loss smoothies after having two kids back-to-back, when stress-eating Goldfish and complete exhaustion made losing weight feel impossible. These smoothie recipes use low-calorie ingredients and nutrient-dense fruits to jumpstart metabolism and support fat loss.

Why Smoothies Help You Lose Weight
Smoothies can be a great tool for weight loss due to their versatility and nutritional density. I started blending a smoothie each morning while doing my 21-Day Cleanse. The natural energy boost gave me motivation to start working out, and within just a week, I began to see results. Some days I even swapped in a second smoothie as a meal replacement smoothie, because it tasted so good! Here’s why they work:
- Fiber keeps you full: Blend a variety of fruits (banana, strawberries, oranges) and leafy green vegetables (spinach, kale, chard) together to create a high-fiber drink that’ll keep you full and satisfied.
- Simple portion control: Measure out the ingredients before you add to the blender to make portion control easy.
- Curb false hunger cues: All my weight loss smoothie recipes use 1 cup of liquid to hydrate your cells, curb hunger, and help your body function properly.
- Quick meal replacement: Use a combination of plant-based protein and healthy fats to create an ideal meal replacement.
- Burns fat: Use ingredients, like green tea and grapefruit, that are packed with nutrients and scientifically proven to burn fat.

Fat-Burning Smoothie Combinations
Certain food combinations can help burn belly fat and lead to overall weight loss. I try to use these combinations in my fat-burning smoothies recipes to get the best weight loss results.
- Green apple + nut butter: Apples are chock-full of fiber, a nutrient that can help reduce visceral fat, while nut butter adds healthy fats that keep you feeling full and support vitamin absorption.
- Avocados + kale: This leafy green can help you slim down by filling you up and giving you a healthy dose of vitamins K and A.
- Green tea + grapefruit: Blend grapefruit into your smoothie along with chilled green tea, which contains pectin and polyphenols. Both of these have been proven to help people feel fuller and lose weight, according to a study published in the Journal of Medical Food.
- Cacao + almonds: Packed with flavanols, cacao can prevent people from gaining weight, according to a study published in BMJ, and may increase energy expenditure.
- Oats + blueberries: Oats are high in fiber, helping you stay full. Toss in some berries and it’s a power combo! A study out of the University of Michigan found that rats who had blueberry powder mixed into their meals had less abdominal fat than rats on a berry-free diet after 90 days.

I’ve created so many weight loss smoothies, and while I love a lot of them, the one I’ve included below is hands-down the healthiest. It’s packed with metabolism-boosting greens, fiber, and superfoods that help curb cravings and keep me feeling energized. If you’re looking for a go-to smoothie to support your weight loss journey, this is the one! Here’s how to make it:
- Fill your blender with kale, cucumber, celery, and cooled green tea.

Juicing and blending can both help with weight loss, yet only one is sustainable for the long run: smoothies. We believe committing to drinking 1-2 fat-burning smoothies as a meal replacement is the most effective way to hit your weight loss goals and maintain them for life.
Yes, fruit smoothies can be great for weight loss when made with whole fruits instead of fruit juices. Whole fruits contain fiber, which helps slow digestion, keeps you full longer, and prevents blood sugar spikes. In contrast, fruit juices strip away fiber, leaving mostly sugar, which can lead to energy crashes and increased hunger. For a weight-loss-friendly smoothie, use whole fruits, balance with protein and healthy fats, and avoid added sugars.
Smoothies that support weight loss are packed with fiber, healthy fats, and metabolism-boosting ingredients. Look for recipes with whole fruits, leafy greens, protein, and ingredients like green tea, grapefruit, and avocado to help burn fat and keep you full.

Hi what quantity is a cup, a teacup?Thanks
Hey Chris – great question! We like to say a cup of spinach is about a good handful.
What does this taste like? Is it going to be sweet or veggie tasting?
Hey Sandra – While the pineapple does add a touch of sweetness, this is def not as sweet as other recipes containing things like banana, fig, maple syrup, etc. It’s more toward the savory or veggie end of things. 🙂
What would be a good substitute for similar benefits as the grapefruit and orange as I am allergic to both?
A granny smith apple!
I just made a different smoothie that had spinach, cilantro, ginger, frozen pineapple/avocado, lime juice, and a granny smith. It was amazing. Aparently granny smiths are fat burners too, from what I had read. I assume they would be great in any green smoothie.
Hi there Noella,
Great question! You can totally swap out orange or grapefruit using tangerine (if you can have those), papaya or mango. Check out our Rawkstar Substitution Guide for more helpful swaps!
I run cross country meets in the morning around 7-8 but I still need to eat something before I leave to have some energy when I run. Should I have the smoothie before I leave or would that mess with my stomach? Thanks!
Hey Aria. I used to run cross country! I would stick with oatmeal, toast with banana and almond butter 1-2 hours before the race and then have my smoothie after the finish line. Store it in a thermos so it stays cold. This is actually one of my fav post run smoothies. Good luck with training and your meets!
Can lemon be substituted for grapefruit? My medication prohibits eating or drinking grapefruit. thanks.
The recipe sounds really good. I read many comments but didn’t find any that said whether they lost weight. Did anyone lose weight using the Fat Burning Weight Loss Smoothie? If someone did, how many pounds per week?
Hey Jo— if you’re really wanting to lose weight, it’s about consistency. Healthy habits is how you gain momentum and the weight will continue to fall off. So a daily green smoothie just like this one is a great way to go. If you’re wanting more guidance and support, check out our 21 day cleanse which starts with a daily green smoothie, yet adds in plant-based snacks and meals as well. The results are incredible and you learn how to eat in a way that is tasty and heals the body in incredible ways.
It’s not quite that simple, though it does work. Time of day is also crucially important. Eating right before bed for example causes weight gain beyond “calories in calories out” because melatonin (the sleep chemical) naturally causes the body to store more fats
I agree Dean— there’s soooo many reason why we gain and lose weight. Yet embracing a simple healthy habit and doing it consistently does lead to long term results that stick. When you swap a meal with a smoothie just like this one, you are adding is tons of goodness that will help burn fat and feel amazing. Some other things that help are hydration, movement, sleep and mindset. They all play a role in getting our body to function at its best. I love talking about this stuff, so thanks for bringing it up!
What time of the day is best to have this smoothie? I usually like to eat oatmeal in the morning, should I switch it up? Also I have vegan protein soy powder, do you think this could be added into the smoothie? (:
Hi Pasha! Most of us love drinking our smoothies in the morning but really, any time of day that works for you is the right time to have your smoothie. If you want to switch it up you can or you can have your smoothie first and a little later, your oatmeal.
I love this smoothie it is one of the best I ever had and yes the avacado curves my appetite. Thank you for sharing:)
You’re welcome, Drea!
Hi, can a large batch of this be made, so that I can have it pre-made and drink it every morning before work? Or will it spoil after a day? Thanks
Hi Jaime! You can def make this ahead of time and keep it in the fridge and/or freezer. It will last 2-3 days in the fridge and a week or more in the freezer. 🙂
Can i use matcha powder instead of green tea? If yes what liquid should i use it with? Also is this ok to drink if im breastfeeding? Im 5 months postapstum and want to loose some weight. I just heard mint reduces milk supply. Please let me know. Thanks.
Hey Tanya. Yes, you can use matcha green tea powder. Just sub water for your liquid base. As far as your other question, we’re green smoothie rawkstars but we’re not doctors and we encourage you to check with your doctor/ob-gyn/nutritionist since they know you, your body and your baby best. Happy blending! 🙂
