Yes — tequila contains zero carbohydrates and is one of the most keto-friendly spirits available. Choose 100% agave tequila blanco (silver) for the cleanest, most authentic margarita flavor and the purest ingredient profile. Avoid flavored tequilas which may contain added sugar.

Allulose produces the closest result to a classic margarita — it dissolves cleanly in cold liquid, does not crystallize, and has no cooling aftertaste like erythritol. Monk fruit sweetener is also excellent. Make a simple syrup by dissolving the sweetener in warm water at a 1 to 1 ratio before adding to the cocktail.

A keto margarita made with 2 ounces tequila, 1 ounce fresh lime juice, and a sugar-free sweetener contains approximately 2 to 4 grams of net carbs — almost entirely from the lime juice. A traditional margarita made with commercial mix contains 20 to 30 grams of sugar per serving.

Alcohol itself contains no carbohydrates but it does temporarily pause fat burning — the liver prioritizes metabolizing alcohol over producing ketones. A single keto margarita will not end ketosis but will slow it temporarily.
