Key Takeaways
- A low calorie margarita (skinny margarita) lands around 100–150 calories by using blanco tequila, fresh lime juice, and a measured sweetener instead of triple sec and sour mix.
- Classic margaritas often reach 200–500 calories and up to 31 g of sugar, so removing orange liqueur and pre-made mix cuts the largest calorie load.
- The core build uses 2 oz tequila, 1 oz fresh lime, ½ oz orange element, and ¼–½ oz sweetener (agave or zero-calorie) for roughly 98–183 calories.
- At bars, use the exact script “fresh lime juice, soda water, no triple sec, no simple syrup” to avoid hidden sugars in house mixes.
- Little Saints offers a zero-sugar, five-calorie Classic Margarita as a ready-to-drink, no-build option for the same margarita occasion.

The Problem: Why A Classic Margarita Is A Sugar Bomb
A classic margarita made with tequila, triple sec, and sour mix runs 200–300 calories per 4-ounce serving. Restaurant versions poured at 6–8 ounces can reach 300–500 calories with about 41 grams of carbs and 31 grams of sugar. The reason sits in the orange liqueur and the sour mix.
Triple sec or orange liqueur adds 75–100 calories and 11 grams of sugar per ounce. Bottled sour mix adds roughly 110 calories and 28 grams of sugar per 4 ounces. A standard margarita contains roughly 7 teaspoons of sugar, which exceeds the American Heart Association's recommended daily added sugar limit of 6 teaspoons for women and 9 for men.
The skinny margarita exists to close that gap. Removing triple sec and replacing sour mix with fresh lime juice and sparkling water produces the largest single reduction, cutting about 75–100 calories per ounce of liqueur removed and eliminating 28 grams of sugar per serving from pre-made mix. Once those two ingredients are gone, the sweetener becomes the remaining variable and the only lever that meaningfully moves the final number.
The Solution: The Definitive Low Calorie Margarita Build
With the calorie math established, here is the build that puts it into practice. Every ingredient earns its place, and nothing is decorative.
Ingredients:
- 2 oz blanco or silver tequila
- 1 oz fresh lime juice
- ½ oz orange element, where freshly squeezed 100% orange juice contains about 45 calories per 100 g and a dry orange liqueur such as Cointreau l'Unique (40% ABV) contains 93 calories per 30 ml serving (about 46–47 calories per ½ oz); the calorie difference appears in the math section below
- ¼–½ oz sweetener, either agave nectar or a zero-calorie option (see the sweetener trade-off section)
- Kosher salt for the rim
- Ice
Method:
- Run a lime wedge around the rim of a rocks glass and press it into a shallow plate of kosher salt.
- Combine tequila, lime juice, orange element, and sweetener in a cocktail shaker with ice.
- Shake hard for at least ten seconds. Citrus drinks need aeration for texture.
- Strain over fresh ice into the prepared glass.
- Garnish with a lime wheel.
For a longer, lower-calorie build, top with 2–3 oz of plain sparkling water after straining. This adds zero calories, more volume, and keeps the same flavor frame.

How Many Calories Are In A Skinny Margarita? The Math By Ingredient
The tequila sets the calorie floor. The sweetener moves the total. Everything else stays fixed and small. Here is the per-ingredient calorie breakdown for the build above:
| Ingredient | Measure | Approximate Calories |
|---|---|---|
| Blanco tequila (80-proof) | 2 oz | ~129 calories |
| Fresh lime juice | 1 oz | ~8 calories |
| Fresh orange juice (orange element, lower-calorie option) | ½ oz | ~7 calories |
| Dry orange liqueur (orange element, classic option) | ½ oz | ~47 calories |
| Agave nectar (sweetener, standard option) | ¼ oz (~½ tbsp) | ~20–30 calories |
| Zero-calorie sweetener, such as monk fruit or stevia (sweetener, low-cal option) | To taste | 0 calories |
| Plain sparkling water (optional lengthener) | 2–3 oz | 0 calories |
A skinny margarita made with fresh orange juice and a zero-calorie sweetener such as stevia contains approximately 98 calories. A skinny margarita made with agave nectar and fresh orange juice typically contains roughly 114–183 calories depending on the recipe, with The Cookie Rookie's version at 170 calories and Taste of Home's at 183 calories. Using 1 oz of dry orange liqueur (97–110 calories) plus 1 tablespoon of agave nectar (60 calories) yields approximately 204–214 calories. That total still sits well below the 300–500-calorie restaurant version, but the sweetener and orange element together account for the entire range.
Note: A 1.5 oz pour of 80-proof tequila contributes approximately 97 calories. This build uses 2 oz, which is the standard cocktail pour and explains the higher tequila figure above.

The Sweetener Trade-Off: Agave Vs. Zero-Calorie Options
The sweetener is the only ingredient in a skinny margarita that meaningfully changes the calorie total. Tequila and lime stay fixed, and fresh orange juice already sits low. The decision lives in the sweetener choice.
Agave nectar adds 40–60 calories per tablespoon and Monin Organic Agave Nectar adds 25 calories at the ¼ fl oz (7.5 mL) measure used here. It integrates smoothly with tequila's agave base and rounds out lime's acidity without a perceptible aftertaste. The trade-off is real calories and real sugar, since agave nectar contains approximately 5 grams of sugar per teaspoon (about 16 grams per tablespoon), and a ¼ oz pour weighs about 10.9 grams total.
Zero-calorie options remove that sugar entirely. Monk fruit extract is approximately 100 to 250 times sweeter than sugar, calorie-free, and classified as GRAS (Generally Recognized As Safe) by the FDA. It often lacks the bitter aftertaste that can appear with some stevia products because mogroside V, the primary sweet compound in monk fruit, binds almost exclusively to sweet taste receptors, while some stevia compounds also bind to bitter receptors. In a margarita, where lime's tartness already leads, monk fruit's clean sweetness profile helps.
Stevia is approximately 200 to 400 times sweeter than sugar and also calorie-free with GRAS status for high-purity extracts. Higher-purity Reb-A stevia extracts carry less of the bitter edge, while cheaper extracts carry more. In a citrus-forward drink, a small amount of high-purity stevia works well.
One label detail matters here. Many products labeled "monk fruit" or "stevia" are blended with erythritol or other sweeteners, so the full ingredient list should be read instead of assuming a single-ingredient product. The bulking agent in the blend shapes both calories and taste.
The bottom line on the sweetener trade-off: agave buys seamless integration and costs 20–30 calories and 5–7 grams of sugar. A zero-calorie option removes those calories and lands the drink at approximately 98 calories with no added sugar. Both are valid choices, sitting at different points on the same trade-off curve.

How Do I Order A Skinny Margarita At A Bar?
Once you know the build, the next challenge is getting a bar to make it. Here is the exact script that keeps calories in check.
The ordering script: “Fresh lime juice, soda water, no triple sec, and no simple syrup, on the rocks.” If some sweetness is wanted, add “just a small amount of agave” or “half the usual sweetener.”
Before ordering anything, ask: “What is in the house mix?” Pre-made bar mixes can add 80–120 calories before the spirit even enters the glass, and a bar's “skinny” margarita may be built from a lite concentrate that shaves only 30 calories off the original.
“Skinny” has no regulated definition at bars, so the bartender at a craft cocktail bar and the bartender at a chain restaurant are both free to use it however they like. That is why specific ingredient instructions such as “no triple sec” and “fresh lime, not sour mix” land with bartenders, while vague wellness goals like “make it healthy” are interpretable a dozen ways and usually result in a full-sugar pour.
If the bartender reaches for sour mix anyway, redirect with “Actually, could you use fresh lime juice and just top it with soda water instead?” Most bartenders accommodate a single, polite modification request.
The drink that results from this script is essentially a Tommy's Margarita build, which uses blanco tequila, fresh lime, and a small amount of agave with no orange liqueur, sometimes lengthened with soda water. It lands at approximately 110–145 calories depending on the tequila pour and sweetener amount, compared to 250–300 calories for a classic margarita made with triple sec and a sweetened house mix.

What Is The Lowest Calorie Margarita Mix?
Club soda, plain soda water, and unsweetened sparkling water contain 0 calories and 0 grams of carbs per 8-ounce serving. They are the lowest-calorie margarita mixers available and still support the drink's flavor.
A tequila-and-soda build with fresh lime, using 1.5 oz blanco tequila and 1 oz fresh lime juice topped with soda water, delivers approximately 97–105 calories per drink with negligible carbs. This build does not meet the IBA's technical margarita definition, yet it captures the same tequila-and-lime flavor frame at the lowest possible calorie count.
For a longer drink that still reads as a margarita, use the full build from the recipe section above and top with 2–3 oz of sparkling water after straining. The added volume extends the drink without adding a single calorie.
One mixer deserves a clear warning: tonic water. Regular tonic water contains 90 calories and 22 grams of carbs per 8-ounce serving, which nearly doubles a drink's calories. It sounds like soda water but carries sugar, so always specify “soda water” or “sparkling water,” not “tonic.”
Grapefruit- or lime-flavored seltzers with zero added sugar also work well and add zero calories, but labels matter. Products labeled “sparkling juice” can add 20–60 calories per can.

Is One Margarita A Day Ok?
Two physiological costs are worth knowing because they are measurable and relevant to anyone tracking sleep or body composition.
First, the liver prioritizes burning ethanol over fat, pausing fat oxidation for several hours after a single drink. Alcohol provides approximately 7 calories per gram, more than carbohydrates or protein at 4 calories per gram. Those calories move to the front of the metabolic line.
Second, alcohol fragments REM sleep even at moderate doses. For anyone tracking sleep on a wearable device, this shows up in the data the morning after even a single drink. The effect is dose-dependent and still present at one drink.
These facts do not turn a single low calorie margarita into a problem for most adults. They simply describe the next-day costs the drink carries and let each person set their own line.
The No-Build Option: Little Saints Classic Margarita
Some nights call for the margarita flavor without the shaker, fresh limes, or measuring. On those nights, Little Saints' Classic Margarita serves as the no-build option. It is a finished non-alcoholic cocktail built for the same occasion as the drink above.
The Classic Margarita delivers lime, bitter orange, and salt, with a salt-kissed and bright profile, at zero grams of sugar, five calories per can, and 0% ABV. It is sweetened with monk fruit juice concentrate only, with no erythritol and no sugar alcohols. The Classic Margarita carries organic Reishi, organic Lion's Mane, and Damiana at a stated 100mg functional mushroom dose per serving. The extracts are at a minimum of 70% beta glucan content, documented by supplier certificates of analysis.
That beta glucan figure matters. A whole mushroom bought at a farmers' market sits around 0.1% beta glucan, while the Little Saints extract is up to 700 times more concentrated. Against a dried, ground mushroom at roughly 1%, it is approximately 70 times more concentrated. The mushrooms are USDA Organic, grown in California, and extracted with ultrasound rather than chemical solvents. The extract holds GRAS status, which is the FDA's standard of generally recognized as safe for an ingredient used in food.
The Classic Margarita is rated 4.8/5 across 48 reviews on littlesaints.com, captured August 2026. It is available direct to consumer and at Sprouts nationwide, Whole Foods in California and Florida, Fresh Thyme in the Midwest, and ABC Liquors in Florida.

Frequently Asked Questions
How Many Calories Are In A Standard Skinny Margarita?
Most skinny margaritas fall between 100 and 180 calories per serving, depending on the tequila pour and sweetener. As the ingredient table above shows, the tequila sets the floor and the sweetener is the only variable that moves the total. Builds that use zero-calorie sweetener and fresh orange juice land near the low end of that range, while versions with agave and dry orange liqueur sit near the high end.
Can I Make Skinny Margaritas With Club Soda?
Yes. Club soda adds zero calories and zero sugar, and a tequila-and-soda build with fresh lime lands at approximately 97–105 calories. For a drink that reads more like a margarita, use the full recipe build of tequila, fresh lime, orange element, and a small amount of sweetener, then top with 2–3 oz of soda water after straining. The soda water adds volume and bubbles without changing the calorie count.
What Is The Lowest Calorie Margarita Mix?
The zero-calorie mixers covered above, including club soda, plain soda water, and unsweetened sparkling water, remain the only options that add volume without calories or sugar. Avoid tonic water, since it contains roughly 90 calories and 22 grams of carbs per 8-ounce serving and is frequently confused with soda water at bars.
How Do Bartenders Make A Skinny Margarita?
Many bartenders default to a Tommy's Margarita build, which uses blanco tequila, fresh lime juice, and a small amount of agave syrup with no orange liqueur, sometimes with a splash of fresh orange juice for brightness. At craft cocktail bars, the standard low-calorie margarita is the Tommy's Margarita, created by Julio Bermejo at Tommy's Mexican Restaurant in San Francisco in 1990, and made with 100% agave tequila, fresh lime juice, and agave nectar instead of orange liqueur. At chain restaurants, “skinny” may mean a lite pre-made concentrate, so asking what sits in the house mix remains the safest move.
What Does Making A Margarita Skinny Mean?
Making a margarita skinny means reducing or removing the sugary elements such as triple sec, sour mix, and added syrup, and relying on measured tequila, fresh citrus, and limited sweetener. The result captures the same tequila-and-lime flavor frame at roughly half the calories of a classic build, with most of the sugar reduction coming from eliminating the orange liqueur and pre-made mix.
Is One Margarita A Day Ok?
From a calorie standpoint, a low calorie margarita fits within moderate drinking guidelines as defined by the NIAAA, which allow up to one drink per day for women and up to two for men. As discussed above, the two next-day costs, which include the pause in fat oxidation and the disruption to REM sleep, still apply at one drink. Most adults can absorb those trade-offs, yet knowing them helps with planning.
Conclusion: The Final Pitch
As the math showed, a classic margarita carries roughly 7 teaspoons of sugar and can double or triple in calories with a restaurant pour. Many “skinny” versions on the SERP read as compromises or guesses. This guide treats the low calorie margarita as a clear trade-off. Every ingredient costs calories and buys taste, and the sweetener is the only lever that meaningfully moves the number. Build it to your own line using the spec above, order it at a bar with the exact script in this guide, or skip the build entirely.
For the no-build option described above, Little Saints' Classic Margarita is available now.
