  • 3-4 medium fresh lemons (Meyer lemons, if available)
  • 5 cups water
  • ½ cup Swerve, granular
  • ice cubes, for serving


  • Use the peeler to remove thin slices of the yellow rind from 2 of the lemons.
  • Cut lemons in half. Juice enough lemons to yield ½-cup of freshly squeezed lemon juice.
  • Put the water and Swerve in a small saucepan. Heat the mixture (medium heat) until the Swerve completely dissolves. Stir it occasionally, leaving it on the heat for 15-20 minutes. (Don't let much water evaporate.) The solution will not turn fully clear.
  • Take the pan off the heat and stir in the lemon zest peelings. Let the mixture rest at room temperature for 30 minutes.
  • After the 30 minutes have passed, remove the lemon rinds from the Swerve solution with a strainer. Stir in the lemon juice. Refrigerate your keto lemonade until it is chilled.
  • Serve your keto lemonade in a tall glass over ice with fun straws (if desired). We garnished ours with fresh mint, but that is optional.


This is a level 1 recipe (may help support fat loss). Milk and the occasional whole fruit smoothie aside, limiting calorie-containing drinks is a smart move for weight loss. If you crave sweet drinks, using sugar substitutes may help keep you on track with your health goals.  
One item that I think many should remove from the diet is sugar-sweetened beverages. I’m talking about things like soda pop, sweet tea, drinks made from powdered (mostly sugar) mixes, and so on. It also means beverages with a health halo, such as the sweetened vitamin drinks from the health food store. 
White sugar provides 45 calories per tablespoon, while honey provides 60 calories per tablespoon. Let’s be honest, though, most of us use more than one tablespoon of sugar per serving of lemonade. Switching to a sugar substitute could easily save you 100 calories per glass of lemonade or more. 
Unfortunately, some individuals report that using low carb sweetened beverages worsens their cravings for sweet foods. If this sounds like you, this recipe may not be a good fit.  
For others, this low-calorie, low-carb sweet drink may make it less likely they'll reach for a soda. You're in the best position to determine whether this low-carb beverage has a place in your diet. 
Like caloric sweeteners, you should limit zero-calorie sugar substitutes. Sugar-free drinks may be low in calories, but they shouldn’t displace the nutrient-dense foods you need to be healthy. Additionally, some people report uncomfortable digestive experiences when they overdo it with sugar-free drinks like this one. 
Infused water is a (nearly) zero calorie drink and is my favorite hydration option. Simply throw slices of lemon, lime, or orange in a large pitcher of water. Keep the pitcher in the fridge so you can have a cold drink whenever you want it!
