Weight loss smoothies made with low-calorie greens and nutrient-dense fruits can jumpstart metabolism and support fat loss, aka: burn fat. I discovered this first-hand after having two kids back-to-back, when stress eating Goldfish and complete exhaustion made losing weight feel impossible.
Instead of my usual bagel and cream cheese, I started blending a smoothie each morning. 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—because it tasted so good! Plus, I felt energized, and the scale kept moving in the right direction.

Why Smoothies Help You Lose Weight
Smoothies can be a great tool for weight loss due to their versatility and nutritional density. There’s no easier way to pack in a variety of fruits, vegetables, and protein sources, which can help you feel full and satisfied while reducing your overall calorie intake. Here’s why they work:
- Fiber keeps you full: Blend a variety of fruits (banana, strawberries, oranges) and leafy greens (spinach, kale, chard) together to create a high-fiber drink that’ll keep you full and satisfied. Check out my leafy greens guide.
- Simple portion control: Measure out the ingredients before you add to the blender to make portion control easy.
- Proper hydration curbs false hunger cues: Use 1 cup of liquid (almond milk, water, coconut water) to hydrate your cells, curb hunger, and help your body function properly.
- Ideal meal replacement: Use a combination of plant-based protein (chia seeds, protein powder, etc) and healthy fats (superfoods, nut butter, coconut milk) 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.

What to Put in Smoothies for Weight Loss
Focus on blending ingredients for your fat-burning smoothies that are scientifically proven to burn fat and boost metabolism, which leads to weight loss. It’s important that the calories we consume are quality calories, especially if we’re trying to lose weight, gain muscle, or improve our overall health.
ingredients proven to burn belly fat
- Soluble fiber: Soluble fiber, found in fruits, vegetables, oats and legumes, absorbs water and forms a gel that helps slow down food as it passes through your digestive system. This helps keep you full, so you naturally eat less. Huge plus!
- High-protein: Observational studies show that people who eat more protein tend to have less abdominal fat than those who eat a lower-protein diet. Adding a plant-based protein powder or unsweetened Greek yogurt to your smoothies can be a great way to do this. If you’re doing HIIT workouts, using smoothies as a post-workout protein weight loss shake is highly effective in burning belly fat and promoting muscle recovery.
- Low-sugar foods: Using fruit as your natural sweeter is a great way to cut down on sugar (and avoid the highly processed refined sugars which contribute to belly fat). Using a combination of natural sugars and high fiber foods helps stabilize your blood sugar levels, which helps with weight control.
- Green tea: Using chilled green tea as your smoothie base can help boost your metabolism and energy levels, thanks to the natural caffeine and antioxidant epigallocatechin gallate. According to one 10-year study, people who drink green tea regularly have nearly 20 percent less body fat than those who don’t. EGCG, the unique ingredient in green tea, can deactivate the genetic triggers for diabetes and obesity.
ingredients to avoid when trying to lose weight
- Fruit juice: Avoid using any kind of fruit juice in your smoothie because it adds extra sugars without the nutrients found in whole fruits. It’s much better to blend an apple than to add apple juice to your smoothies for weight loss when trying to lose weight.
- Dairy: Milk, yogurt, and protein powders that contain dairy can cause inflammation in the body… making it harder to lose weight and burn fat. We avoid these in all of these recipes.
- Added sweeteners: Avoid honey, maple syrup, sugar, monk fruit, and stevia in your smoothies because they are high in calories and low in nutrients. Plus, they can spike your blood sugar levels and train your taste buds to crave high-sugar foods throughout the day.
Fat-Burning Ingredient 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.

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.

I will be trying this smoothie again. I added more than a pinch of cayenne pepper, it was drinkable but very spicy. My mistake.
Hi Tammy! Less can definitely be more when it comes to cayenne. I hope you’ll give it an other try sometime!
Ingredients well blended that made this drink an unexpected winner! Since I can’t have grapefruit, I used oranges which gave this a nice citrus taste. I could taste a little celery which was just right. I would drink this again with the green tea added.
Hi Jemia! Oranges are a great subtitute in this one. Glad you made it work for you!
More involved to make but worth the effort and a really interesting combination of ingredients. Definitely one I will try again and maybe switch up brand or strength of green tea.
You’re so right, Nicola! This one is definitely worth the effort.
Loved the variety of ingredients. I would have never thought to put those together but tasted good.
This one is definitely an unexpected combo of flavors, Jean! So glad you gave it a try.
I’m still on the fence with this Fat Burning Smoothie recipe. I really like the pineapple for sweetness and the grapefruit. I like mint and green tea. Maybe it was the celery or something with the combination of ingredients that threw off the taste. True, it wasn’t as sweet as some of the other smoothies in the challenge. Unless I try something differently again, this isn’t one of my regular favorites.
Hi Dawn! You can definitely make some adjustments to make this one work for you! If you think it was the celery, you can always omit.
This wasn’t my favorite smoothie. I really like the ingredients on their own, but it just wasn’t something I enjoyed all mixed together. I suppose if I need energy I could make it again.
Hi Allison! I can definitely see where this one could be hit or miss for some people.
i’m not a big fan of celery and have never liked it in my smoothies; even so, this smoothie isn’t too bad. i made it as written and didn’t add anything after the fact. i felt rather proud of myself just getting it down as is. that said, i think i will try to make it with at least some regularity. it grows on you a bit while drinking it and i could use the purported benefits. thanks for doing this green smoothie challenge, sgs!
Hi Kimberly! So glad you joined me for the Smoothie Challenge and gave this one a go!
I really Love this smoothie. I will be adding this one as well.
Yeahh! So glad to hear you’ll be making this one again, Maryum!
I was surprised how good this tasted. The combination of the grapefruit, mint and celery went well and the dash of cayenne pepper added a kick to it!
So glad this one surprised you, Ada!
I liked this one. It was different from the rest. Green tea and mint are not my favorite, but with the avocado, celery, grapefruit (which is my favorite), pineapple and a pinch of cayenne pepper I only picked up a hint of it. I like this one, but there have been better ones in this challenge. I am open to trying new smoothies.
Woo hoo! So glad you liked this one, Laura!
Not one of my favorite. I swap the grapefruit for orange because I did not have any grapefruit. I did not use any celery or green tea, I don’t like those.
Hi Aldeen! Orange is a great swap for grapefruit in this one.
I would like to print out a Substitution Guide please. I’m a new member .
Hi Glenda! If you’re a Rawk the Year member, you can find the swap guide by logging into the Rawkstar Collective and going to Plant-Based Resources.
My favorite one so far! I love green tea! I can almost feel the fat burning lol
Yeahh!! So glad to hear you’re loving this one, Whitney!
Sorry…..I forgot to rate it the first time……I swapped the grapefruit for orange! It made a refreshing smoothie
So glad you loved this one, Anna!
I swapped the grapefruit for orange! It made a refreshing smoothie
Hi Anna! Great swap for the grapefruit for sure!
Hi, again. Sorry for the repeat comment but I realized that I forgot to rate this smoothie.
I’m usually not a fan of green tea but that ingredient sure kicks this smoothie up a notch. Great smoothie to jumpstart the day.
Hpe everyone is having a great day!!!
Hi Terry! So glad you liked this one. Definitely a great way to jump start the day!
