Have you had the Diet Lemonade from ChickFilA? And do you like it? I have always hated the aftertaste. Many people love their regular lemonade, but I have often found that it is too sweet for me.
Is lemonade keto? Most store-bought is not. Is sugar-free bad for you? If it has artificial sweetners, then maybe. For a while artificial sweeteners were the craze, but now the push is for organic and natural ingredients.

How to Make Keto Lemonade
- Squeeze the juice of fresh lemons using a lemon squeezer or a lemon juicer until you have 2 cups of juice.
- Place a saucepan on medium high heat and add 2 cups of water and 2 cups of sweetener to create a simple syrup.
- Stir continuously until the mixture is clear. It will appear cloudy at first.
- Add the simple syrup and lemon juice to a pitcher along with additional water to taste.

Simple Syrup
This recipe includes instructions on how to make simple syrup from a combination of water and sweetener that you heat on the stove. You can save a little time and work by using this monkfruit simple syrup from Lakanto.

How Many Carbs
One cup of lemonade has 2 net carbs.
Which Sweetener to Use
You can sweeten lemonade naturally by using an organic sweetener like monkfruit. This will keep the recipe refined sugar-free.
Recipe Tips
- The number of lemons you will need will vary based on the size of the lemons you use and how much juice you can get from each. Typically, I use 8-10 lemons.
- The best cheap way to make this recipe is to pick up a bag of lemons from Costco. A bag is usually $6.
- If you are having trouble juicing the lemons, place them in the microwave for 15-20 seconds. This will help soften them up.
- Adjust this recipe to suit your taste and needs. If you like really sweet lemonade, add more sweetener.
- You can heat the simple syrup in the microwave if you wish. Heat it until the mixture turns clear, timing will vary.
- You can save a little time and work by using this monkfruit simple syrup from Lakanto instead of making your own.
- You can make strawberry lemonade using 2 cups of fresh puréed strawberries.

- additional water to adjust to taste I added 5 cups
Instructions
- Juice the lemons using a lemon squeezer or lemon juicer.

can you just use real lemon in the bottle instead of squeezing all those expensive lemons? It only takes one 16 oz. bottle, for 2 cups of lemons. I know it isnt as healthy as fresh lemon W/O the chemicals, buts its a lot cheaper. And I can make it more offend. what do you think?😁

No. $2 for lemons isn’t expensive. If it is for you, do what you want.

This was such a delicious, refreshing lemonade! I also used it as a low-carb mixer with a few shots of vodka and definitely recommend! I’m looking forward to making it many more times this summer.
