Most cocktail drinks are loaded with sugar and are a "no-no" in low-carb diets. This recipe is not zero-carb but the only sugar you get is from fresh fruits. You can occasionally reward yourself with a treat like this one. If you can't drink alcohol, make it without tequila. You can also try this drink with dark or white rum.

I'm using my Watermelon Sorbet but you can simplify the recipe by using frozen strawberries. to do that, use the following ingredients:

  • 1/2 cup frozen strawberries (72 g/ 2.5 oz)
  • 1/2 lime, juiced (30 ml)
  • 3-6 drops liquid Stevia extract, powdered Swerve or Erythritol, to taste
  • 1 shot gold tequila (45 ml/ 1.5 fl oz)
  • 1/2 cup water or ice
  • sea salt and lime for garnish

How Does Alcohol Affect Weight Loss?

Several alcoholic drinks are allowed on a low-carb ketogenic diet. You should avoid all drinks high in sugar like sweet wine, beer and most cocktails. So, which drinks are low-carb? Clear spirits such as vodka, whiskey, tequila, etc. are zero-carb, while dry wine is still low-carb if you drink no more than a glass. If there is no medical constraint (such as liver or kidney condition) and you drink in moderation, there is no reason to give up alcohol completely.

Keep in mind that alcohol will slow down your weight loss progress. Even if there is no sugar, your body can't store alcohol as fat - it has to metabolise it. This means that it will utilise alcohol instead of body fat. You also shouldn't have a large dinner and drink alcohol at the same time.

To quote Atkins on the effects of alcohol:

"The body burns alcohol for fuel when alcohol is available. So, when it is burning alcohol, your body will not burn fat. This does not stop weight loss; it simply postpones it. Since alcohol does not get stored as glycogen, you immediately get back into lipolysis after the alcohol is used up. But keep in mind that alcohol consumption may increase yeast-related symptoms in some people and interfere with weight loss. If it does not slow your weight loss, and occasional glass of wine is acceptable once you are out of Induction so long as you count the carbohydrates in your daily tally."

Another point to make is that ketosis lowers your alcohol tolerance and you have to be aware of it. Because alcohol dehydrates your body, always drink a glass of water while having a glass of an alcoholic drink. This will make you drink less alcohol and stay hydrated.

I'm personally careful with alcohol because it makes me hungry and I tend to eat more. So, if you prefer to avoid alcohol, you can always try Virgin Margarita with no tequila.

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

Are the calories from alcohol considered the same as Carbs?
I know they are a category by them self but what's the take on counting them in a keto diet?

Although calories do count (calories from alcohol still count as calories), you won't likely need to count them on a low-carb/keto diet. Carbs is what you really need to count: KetoDiet Buddy - Easy Macro Calculator for the Ketogenic Diet

So just to clarify, while you are going through the process of becoming fat adapted, alcohol is completely off limits? I’m currently 1.5 weeks into becoming fat adapted and I would love to have a glass of scotch..

Hi Peter, I would personally avoid alcohol during the first 3-4 weeks. But if you do want to have some, a glass of scotch or dry wine should be fine.

I wish I could drink alcohol - this recipe looks yummy!

Great recipe! Thanks

This sounds delightful!  I've been wanting to try some low-carb summer "adult beverages". THANKS!

It's one of my favourite and there will be more, thanks! 😊
