Low Carb, No Guilt Gin Tonic Cocktail

December 12, 2017 (Last Updated: April 18, 2019)

My go-to, no-brainer cocktail is a Gin Tonic.   This classic and easy drink is light, refreshing, and perfect for any occasion.  And the best part is, that it’s low-carb!

About a year ago, I had to switch to a low carb (carbohydrate) diet and I was bummed that I wouldn’t be able to enjoy my favorite cocktail.  Since carbs suddenly became precious, I didn’t want to exhaust my daily allowance in drinks:-)

Gin and Toni served in a tall glass with ice and lime slices

Well, they say that necessity is the mother of all new cocktails (if I may twist the phrase a bit).   I tried several different options, including diet tonic (yuck) and using club soda instead.   

Finally I came to this simple hack: start with a good quality Gin and just replace half the tonic with club soda, and you can barely tell the difference.

Fewer Carbs Than a Glass of Red Wine

In fact, with half the tonic, it turns out that a Gin Tonic has lower carbs and lower calories than a glass of red wine!

Each ounce of tonic water has about 2.5 grams of carbs. Gin has zero carbs. So, a regular Gin Tonic, with 3 ounces of tonic, is about 130 calories and 7.5 grams of carbs, all in the form of added sugar (as much carbs as half a slice of bread). 

The recipe below has 1.5 ounces of tonic (one measure of the Standard Jigger) and 1 ounce of soda, leading to about 110 calories, but only 3.75 grams of carbs.   A glass of red wine has about 125 calories and 3.8 grams of carbs.  See, I told ya!

So, next time you have an urge for a Gin Tonic, try this no guilt, low carb, and lower calorie recipe. This is my favorite low carb cocktail.

By the way, my favorite Gin currently is “Rangpur Tanqueray“; if you haven’t tried it already, believe me its worth a shot.

  • 1/3 cup ice : about 6-8 medium sized ice cubes
  • 1.5 ounces gin : 1 standard jigger. I recommended Rangpur Tanqueray
  • 1.5 ounces tonic water : 1 standard jigger. I recommended Fever Tree Tonic Water
  • 1 ounces club soda or seltzer water : 2 measures of the small side of a standard jigger
  • 1 lemon twist or 2 drops of lemon juice


  • Put ice in a nice high-ball glass
  • Use a standard jigger to add the gin, tonic and soda. I keep my gin in the freezer, so that its absolutely chilled and also use chilled tonic and soda.
  • Twist and add a lemon peel or a full lemon slice to the glass. You can alternatively put a few drops of lemon juice.
  • Stir gently and sip away!

    I was adding water, but will try club soda now. Rangpur Tanqueray makes this work better, since it has a bit of fruitiness already. I also found the Fever Tree Light Tonic is really tasty. It is likely just tonic + club soda, and I can save money by mixing myself.

      Hi Mike, Oh yes, you’ll be able to tell the difference when you switch from water to club soda. I hope you love this version! Thank you!

    Just curious…why not just replace regular Tonic Water with Diet Tonic Water?

      Hi Sheryl, I tired that several times, but diet-tonic has an after-taste, probably from the artificial sweetener, that I did not like at all. It takes away from this refreshing cocktail 🙂
