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 greens 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.

What Do You Put in a Weight Loss Smoothie?
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.
- Soluble fiber: Soluble fiber, found in fruits, vegetables, oats and legumes, help slow down food as it passes through your digestive system. This helps keep you full, so you naturally eat less.
- High-protein: Adding a plant-based protein powder or unsweetened Greek yogurt to your smoothies can increase your protein intake. If you’re doing HIIT workouts, using smoothies as a post-workout protein weight loss 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).
- 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.
How to Make and Store Smoothies
- Most smoothies can be made the night before, so breakfast is ready when you are. Pour your blended smoothie into an airtight jar and refrigerate for up to 24 hours. Fill the jar as full as possible to limit air exposure, then give it a good stir before drinking.
- Make frozen meal prep smoothie packs to have pre-made bags of smoothies in your freezer to make when you want.

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.

How to Make a Weight Loss Smoothie
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 my favorite. 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.
- Puree together until the ingredients reach a smooth consistency.
- Add grapefruit and frozen pineapple. If you want to lower the bitterness of the grapefruit, be sure to remove the inner membrane in addition to the peel. If you can’t tolerate grapefruit, swap with oranges and lemon. If using fresh, follow my guide to cut pineapple like a pro.
- Blend the ingredients until combined.
- Pour into a glass and serve chilled for the most refreshing taste.

- The pith and peel of the grapefruit are extremely bitter but are beneficial in small amounts. To lessen the bitterness of the grapefruit, remove the fruit from the inner membranes as well as peel before using.

- Adding homemade protein powder is a great way to add high-quality protein that won’t affect the delicious taste of the smoothie.

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.

I have a very old Fresh 21 set of recipes so will be very happy to have some additional recipes to help; also does your Daily Blends app have these new smoothie recipes? Thank you for all that you do to help our health for all these years. Love your work so much.
Hi Jennifer! Unfortunately, we no longer update the Daily Blends app. I’d suggest using the recipes on the blog or maybe even joining Rawk The Year for access to other recipes!
Refreshing, almost too sweet. Still favor the “green” smoothies.
Thanks for trying it out, Christine. It’s good to know what works for us and doesn’t.
Looking forward to trying your smoothies and losing some weight.
Thank you for the support and encouragement
We’re here, Tracey. Congrats on starting your journey to better health.
Just an aside…folks on BP meds have to avoid grapefruit…for some reason those 2 things dont get along! Luckily your recipes are good enough without it…Thanks…
Thanks for posting this info, Katt.
I love the receipts! I am making bags and freezing them
Yeahh! So glad you’re loving these, Xochitl!
Hi, when I make the kale smoothie it makes about 5 cups, am I supposed to drink all 5 cups? Is one cup 360 calories or all 5 cups? Thank you.
Hi Christine! If you’re making it by the recipe, then it’s one serving! The calories are for 1 serving or the whole smoothie. Some smoothies make more than 1 serving, so definitely check that when you’re making it.
Can’t wait to try these recipes.
Did you give this one a try? If so, I’d love to know what you thought!
explanations are clear and direct very genuine attitude and energy plus full of inspiration . thank you for who you are and what you . many blessings
Thank you John. Appreciate you taking the time to say this. Keep on blending!
This is a delicious recipe! I make this frequently as a substitute for my usual creamy go-tos. I don’t usually have avocado, so I use a little banana instead. I use decaf green tea. Today I realized I didn’t have pineapple, so I subbed mango, and it was just as good! A very versatile recipe!
I love how you’re swapping it around based on what you have— this is a great way to go! A daily green smoothie is such a powerful habit to embrace when it comes to make healthy habits and weight loss a priority. Keep it up Elizabeth!
Would you do the whole orange as a replacement for the grapefruit?
I could Chast. Just peel it first then blend the rest in your blender (I don’t even take out seeds— since a high speed blender can puree it all).
I can’t use grapefruit due to it interacting with my medicine, what can I sub for it with the green smoothie? So glad I found your website I can’t wait to try these all out!
I’m silly – I just saw a reply to the same question. I’ll try orange!!
Not silly at all. Thanks for giving it a go.
Hi Ashley! You an definitely use orange in this one if you can’t do the grapefruit!
I would also like a substitute for the grapefruit because of a medication.
Thanks!
Hi Suzy! Oranges or a similar citrus fruit would be a great substitute in this one.
What substitute fruit can be used instead of grapefruit?
Some people cannot consume grapefruit because of interaction with some medication.
Please let us know if a replacement fruit would make a difference.
Thanks.
Hi Cole! You could definitely substitute oranges or a similar citrus fruit for the grapefruit in this one!
It was great. I forget to comment when I print them out . Thank u very much
Yeahh!! So glad you like this one!
I cant have grapefruit is there something I can replace it with
Hi Joann! Oranges or a similar citrus fruit would work as a substitute for the grapefruit.
Is there a substitute for the grapefruit? I can’t have it due to medications. Thanks!
Hi Ronnie! You can definitely substitute the grapefruit in this one. Oranges or a similar citrus fruit can be used in its place for this recipe.
Wow delicious
Woo hoo! So glad you liked this one, Misty!
I wasn’t sure about this one but it was delicious. The grapefruit and mint combination came through in particular.
So glad you gave this one a try even though you weren’t sure about it, Manuela!
Wow! This is my new favorite. The celery adds a freshness that makes it feel clean and the mint somehow adds to the freshness, renewal of this blend. Definitely will be repeated in my routine blends.
Rawkin’ Terri! So glad to hear that this one is a new fave of yours!
The smoothie was yummy. Especially love, the combination of grapefruit and mint! My only suggestion is to add one more frozen ingredient because it doesn’t seem to get very cold. I stuck mine in the freezer for a little while, and that took care of it.
Hi Sally Jo! Great suggestion!
