How many carbs are in skinny margarita?

It’s the first day of spring and I am SO excited about it! It’s no secret that I don’t love cold weather and I am looking It’s the middle of spring and I am SO excited about it! It’s no secret that I don’t love cold weather and I am looking forward to sitting on the porch, sipping a frozen watermelon cocktail and watching the world go by. Not that it ever happens that way. You know, life gets in the way when you are making other plans. But I love the idea of relaxing with a cool low carb frozen margarita. This skinny watermelon margarita certainly hits the spot.

Losing weight always sounds like a great idea but it almost never sounds like fun. After all, you generally have to give up all the good things that you love to indulge in. Or at least that’s what we assume. With skinny cocktails you really don’t have to give up much of anything. The calories are kept low with sugar free syrups and clear alcohols like vodka, rum, gin, and tequila that just so happen to have 0 carbs.

That said, you do need to watch how often and how much you drink though. One day a week or less is fine but alcohol will slow down your weight loss efforts even if it isn’t knocking you out of ketosis.

How do you make a skinny watermelon margarita?

  • To make this skinny cocktail low carb, instead of using real watermelon juice or fresh watermelon juice which has lots of sugar aka carbs, I use sugar free watermelon flavored syrup. Some recipes I’ve seen even use a little simple syrup to up the sweetness. Since simple syrup islots of sugar dissolved in water, it has no place in our low carb lifestyle.
  • If you’d like more watermelon flavor you can float an extra tablespoon of sugar free watermelon syrup on the top of the drink.
  • If you want to make a pitcher of margaritas, place your cursor over the number “1” to the right of the heading “Servings” in the recipe card. A slider will appear and you can use your cursor to slide it higher for the number of servings you want to make. The ingredient amounts will adjust automatically for you.
  • To keep this margarita recipe low carb and skinny you don’t want any added sugar. So things that other margarita’s have in them like orange juice, honey, any fresh juice, any fresh fruit, and any for of simple syrup like jalapeno simple syrup should be avoided. Or used very sparingly.
  • To make this an on the rocks skinny watermelon margarita, you can add some sugar free watermelon syrup dissolved in water that you put into your ice cube tray. That’ll give you these tasty ice cubes with a wonderful watermelon color. Yes, you just made watermelon cubes. Or pink ice cubes that look amazing in your margarita glass.
  • The watermelon flavors in this cocktail can’t really be overpowered by the tequila that is used in this recipe. Just use a mid-grade tequila and avoid the gut-rot stuff we used to drink as kids. A good silver tequila works great in this margarita recipe as well as other keto cocktails on Lowcarb-ology.com
  • For parties make these in Mason jars and seal with the screw on tops. To make them go further, add sugar free Sprite instead of ice. Put the Mason jar filled drinks in a tub of ice to chill thoroughly.
  • Garnishing with a wedge of chilled seedless watermelon as it won’t add too many carbs and it looks pretty. A lime slice works just as well and has 0 carbs. In fact I like to use lime juice to coat the rim of my margarita glass and add a combination of salt and just a dash of chili powder for color and a real kick of flavor.

This bartender’s set has everything you need to mix fabulous cocktails all summer long. What I love about my set is that the black stainless steel looks absolutely amazing. And it’s way easier to keep clean and looking great than a shiny stainless steel finish. The cocktail shaker is plenty big to make two glasses of this skinny margarita at a time. I like the wine stoppers too as I really try to limit myself on how much wine I drink in one sitting. This helps keep a bottle good until the next time I get around to it which can be several days. The best thing about this is the jigger for measuring the amount of alcohol you put into your drinks. It sure helps me stay honest and not over serve myself or my guests.
