Are you looking for a cooling summertime drink? If so, you need this refreshing banana watermelon smoothie recipe in your life! This watermelon and banana smoothie for weight loss is low calorie and packed with sweet fruits. They sweeten summer beverages very well with no refined sugar added! Your family will love this colorful drink to help cool off on hot summer days.
This watermelon banana smoothie is my husband’s favorite smoothie on the site. It’s got a great combination of sweet, creamy, and delicious going on.
Seriously, among all the no added sugar smoothies here, he thinks this one is the BEST smoothie. Keep in mind, we’ve been drinking a lot of smoothies lately. This watermelon and banana smoothie is the one that came out on top.
Since banana and watermelon are both extremely sweet fruit, I added some kiwi and raspberries into the mix. Raspberries and kiwi are slightly tart and help the sweetness from becoming too overwhelming. After all, we don’t want to get too much of a good thing.
You could skip the frozen kiwi layer in this smoothie to simplify things. If you try it, it adds a nice green layer that sort of makes the drink resemble a watermelon.
Is there anything better than enjoying healthy and refreshing watermelon in the summer? My goodness, so good.
(Psst... Another favorite easy watermelon recipe of ours is the watermelon lime mint popsicles. We seriously cannot get enough!)

Though nutritious, this banana watermelon smoothie is not a good fit for low carb and keto diets. Bananas and watermelon are both high in natural sugars, and thus high carb foods.
Watermelon is rich in the antioxidant lycopene as well as provitamin A. Like other fat-soluble vitamins though, vitamin A is best absorbed in the presence of a dietary fat source. (Is this an excuse to top your smoothie with some full fat whipped cream? I’ll leave that up to you. Haha)
🥤 Watermelon and Banana Smoothie for Weight Loss Ingredients
To make a watermelon banana smoothie, you need:
- 3 cups seedless watermelon (about ½ mini watermelon)
- 1½ frozen overripe bananas
- ⅓ cup frozen raspberries
You’ll also need a good knife to cut the watermelon and a food processor or high-powered blender to blend the smoothie. It’s important that whatever blender you use is strong enough to make the frozen fruits completely smooth. I also like to have large-width paper straws on hand for serving these smoothies.
🍌 How to Make a Watermelon Banana Smoothie
Begin by preparing the fruit. Cut the rind off the watermelon and cut it into ¾-1-inch cubes (1.9-2.54 cm). Cut the frozen bananas into smaller pieces for easier blending as well.
Place the watermelon, frozen banana, and frozen raspberries in a food processor and blend until smooth. Pour the smoothie into glasses and serve immediately. Enjoy!
Leftover smoothie becomes too liquid when left in the fridge. Instead, consider pouring your leftover smoothies into silicone popsicle molds, and making popsicles! Bananas makes things creamy while frozen watermelon makes things icy, so you get the best of both worlds here.
💭 Expert Tips from a Dietitian
This is a level 2 recipe (transition or weight maintenance). Is a watermelon and banana smoothie healthy? As I’ve said many times before, what’s “healthy” depends on the needs of the individual, so it depends.
If we’re thinking about health in terms of nutrient density, this smoothie is a nutritious choice. It’s packed with fiber, vitamin C, an assortment of B vitamins, potassium, magnesium, and more. You’re getting all that good stuff for only about 150 calories of “real” whole food.
On the other hand, what if you’re improving your health with a very low carb or keto diet? In that case, fruits like bananas and watermelon may not be the best choice for you. Making smoothies with berries and plain Greek yogurt is a better option to keep the carb count down.
Does watermelon help you lose weight? Eating watermelon doesn’t make you lose weight; it is a calorie deficit that leads to weight loss. Watermelon can be a good fit for weight loss diets because it provides a lot of volume for few calories.
However, you don’t have to eat watermelon to lose weight. It’s just one of many options that might help if you are a volume eater.
This smoothie recipe is a snack or side dish; it doesn’t have the macro balance to make it a full meal. You should enjoy some foods with protein and fat along with this smoothie for a satiating meal. For instance, you could serve the smoothie with some eggs and buttered toast for breakfast.
To lighten this recipe up, you can swap the 2% milk for skim milk in the kiwi layer. You could also choose to skip the optional kiwi layer altogether. The combination of banana and watermelon is delicious all by itself!
You’re welcome to add your favorite milk (such as dairy, almond, coconut milk, or oat milk) to this smoothie. Using soymilk or dairy milk will add protein. Use frozen watermelon instead of fresh watermelon if you’re worried the milk will make the smoothie too thin.
This is a watermelon banana smoothie without yogurt, but you could use some plain Greek yogurt in place of the raspberries if you wish. Greek yogurt will add calcium and protein to your smoothie, without sacrificing that bit of tart from the berries.
Try adding pineapple for a banana watermelon and pineapple smoothie! Some other fruits that go well with watermelon are strawberries, apple, grape, mango, orange juice, lime juice, and lemon juice. Another idea: make a banana melon smoothie with cantaloupe or honey dew melon. Cucumber is technically a botanical fruit, and it goes great in smoothies.
Don’t add ingredients to your smoothie that you don’t like the taste of! Also, if you don’t have a high-speed blender (like a Vitamix) don’t use ingredients that are hard to blend into smoothies. This includes spinach, rolled oats, and whole nuts and seeds (like chia seeds and flax seeds). Peanut butter and protein powder are easier to blend.
Very cold drinks, using a straw, big portions, and high fiber foods may actually lead to some gas and bloating, not prevent it (source). One way to decrease bloating is to add more fiber to your diet gradually. This gives your GI system time to adjust to your diet change, ideally leading to fewer unpleasant symptoms.
