What is Sugar Free Lemonade?

Sugar free lemonade is a refreshing drink without any added sugar. It’s typically made using fresh lemon juice, cold water, and a zero-carb sweetener like stevia or monk fruit sweetener. This combination creates a tangy, citrusy beverage that is lightly sweet without traditional granulated white sugar.

With a low calorie count, sugar free lemonade is a delightful drink for those wanting to savor the taste of summer while also maintaining a bikini-ready beach bod. It’s perfect for a hot summer day, providing the satisfying tart sweetness of traditional lemonade without the guilt.


Benefits of Sugar-Free Lemonade

One of the primary advantages of sugar-free lemonade is its low calorie count, making it an excellent option for those who don’t want to sacrifice taste while reducing their caloric intake. Additionally, because it is made with an alternative sweetener to granulated white sugar, highly sensitive alpha gals who must avoid sugar processed with bone char can safely use this sugar-free lemonade recipe. 

How Many Calories in Sugar Free Lemonade?

With nearly all the calories coming from freshly squeezed lemon juice, each 8-ounce serving of this sugar free lemonade has less than 15 calories.

Just like you can’t have a pool party without water, you simply can’t make lemonade without these zesty yellow gems. When crafting your sugar-free lemonade, the type of lemons you choose can make a difference in the final flavor. 

When most people hear the word “lemon,” they think of standard lemons, also known as Eureka or Lisbon lemons. They have a bright yellow color and a tangy, acidic flavor that is perfect for lemonade. These lemons are widely available and can be found at any grocery store.

Meyer lemons are a smaller, rounder variety of lemon with smooth skin that is a deep yellow to orange color. Native to China, Meyer lemons are a hybrid fruit that is a cross between a lemon and a mandarin orange. Because they are sweeter and less acidic than standard lemons, you may need less sweetener if you use Meyer lemons to make this sugar free lemonade recipe.

Sage Advice: Although I prefer to juice fresh lemons for this recipe, you can also use bottled lemon juice to make a pitcher of this refreshing drink even faster.

Selecting the right sweetener for sugar-free lemonade is like picking the perfect pool floatie – choose wisely, and you’re set for a sweet, smooth ride. I used organic stevia to make this recipe. Derived from the stevia plant, it is a natural, healthier alternative to traditional sugar, sweetening without the additional calories or negative effects on blood sugar levels. 

You can easily substitute any other sweetener that’s equivalent to ⅓ cup of granulated sugar. However, choosing a sugar free sweetener that easily dissolves in lemon juice and water is important. Some popular choices include monk fruit sweetener and liquid stevia.

Sage Advice: While not low-sugar options, other alpha-gal friendly alternatives to granulated sugar include agave, honey, and maple syrup. If you choose these alternative sweeteners, be sure to use a blender to incorporate them into the lemon juice since they don’t dissolve as easily as a granulated sweetener.

Along with your chosen sweetener, water is essential for converting lemons into lemonade. Without a few cups of water, lemonade would just be sweetened lemon juice – talk about a summertime buzzkill! For best results, use cold filtered water when making sugar free lemonade. This helps to enhance the overall taste and ensures a crisp and refreshing drink. However, for a unique twist, you can also use chilled sparkling water, adding a touch of bubbly to your lemonade.

How to Make Sugar Free Lemonade

Making sugar free lemonade is fast and easy. Just follow these simple steps:

  1. Squeeze fresh lemons to produce about one cup of lemon juice.
  2. Pour the fresh lemon juice into a pitcher and stir in the sweetener.
  3. Add cold filtered water to the pitcher and stir.
  4. Enjoy sugar free lemonade over ice. Feel free to garnish your glass with a twist of lemon or a sprig of mint – or perhaps a tiny beach umbrella if you’re feeling particularly fancy.

Making sugar free lemonade at home is an easy, healthy alternative to store-bought options. With just three simple ingredients, you can be sipping a refreshing, guilt-free beverage in minutes.

Sage Advice: You’ll also love this frozen lemonade. It comes together quickly in a blender and is extra refreshing on a hot summer day.

Once you’ve mastered this homemade sugar free lemonade recipe, you can zhuzh things up with one of these flavor variations.

For a soothing, floral lemonade option, make lavender syrup using your preferred sugar or sugar substitute. Use ⅓ cup of the lavender simple syrup in lieu of the sweetener in the recipe below.

Watermelon Lemonade

Puree some fresh watermelon and add it to the lemonade to combine the sweetness of this summer fruit with the tartness of lemon.

As you explore these flavor variations, be sure to adjust the sweetness according to your taste. 

Storing Sugar Free Lemonade

It’s hard not to drink the entire pitcher of this sugar free lemonade in one day. But if, by an impressive act of self-restraint, you do have leftover lemonade, transfer it to a sealed container before storing it in the refrigerator for up to four days. This will help to prevent any unwanted flavors or odors from seeping into the lemonade. (I’m looking at you, leftover tuna salad!)

    I have a pretty serious sweet tooth so if I can have a great drink without sugar sign me up. This was perfection. I might add some watermelon or cantaloupe however, next time just for variation.
