Diet Myths About Tequila & 5 Low Carb Tequila Drinks for GLP-1 Diets

We fact check the viral myths about what’s the healthiest spirit, and share 5 low carb tequila drinks for a GLP-1 diet with no sugary mixers.

You’ve seen the viral claims that tequila is the best spirit to consume if you’re dieting. Agave sugar supposedly won’t spike your blood sugar the way other sugars do. A shot of tequila supposedly runs lighter in calories than other liquors. It’s somehow the “clean” choice at last call. It’s the kind of claim that sounds just plausible enough to repeat at a dinner party, which is exactly why it’s worth actually checking before you believe it.

Getting to the bottom of claims like this one is a big part of how I got to my 100-pound weight loss on Wegovy — sorting real nutrition science from marketing, one ingredient at a time. The same instinct that had me questioning “low glycemic” labels and health-halo packaging is what sent me digging into where the tequila claims actually came from, what the research really shows, and how tequila stacks up against a straightforward glass of vodka, whiskey, or gin. If you’re watching your carbs on a GLP-1 diet, where blood sugar stability actually matters, this is worth five minutes before your next order. It’s also not the first ingredient we’ve caught getting oversold this way — we ran into the same pattern debunking fake avocado oil claims.

Below, we’ll walk through where the tequila diet myths came from and what the science actually says, then get to the fun part: 5 low-carb tequila drinks for a GLP-1 diet that don’t need the myth to taste good.

The Viral Claim: Is Tequila the Lowest Carb Spirit?

The claim shows up in a few forms. Tequila supposedly runs lower in calories than other liquors. Agave sugar supposedly won’t spike blood glucose the way cane sugar does. Tequila supposedly supports gut health and blood sugar control. Some posts even cite “a study” on tequila and diabetes. Most of it traces back to tequila’s “clean” reputation — silver, on the rocks, no syrupy mixer — which reads as a health halo even though it isn’t one.

What the Tequila Diet Myths Get Wrong

Here’s the real study behind the claim. Researchers gave mice agavins — a fiber-like compound from the agave plant — dissolved in drinking water. The mice ate less and showed lower blood glucose (PubMed, 2017). That result is real. But the mice drank agave fiber in water, not tequila. Fermentation and distillation break down most agavins before they ever reach the bottle. Dietitians have pushed back hard on the leap from “mice given plant fiber” to “diabetics should drink tequila” — one called it an unsafe stretch, not just a scientific one.

Some tequila marketing also rounds a shot down to 69 calories. Skip ahead to the real number below.

Tequila Calories vs. Vodka: The Real Numbers

A standard 1.5 oz shot of tequila runs about 97 calories. Vodka, gin, whiskey, and rum land in the same range, per USDA-sourced nutrition data. Distilled spirits get their calories from ethanol and proof, not from the plant or grain they started as. Once alcohol is distilled, almost nothing else from the source ingredient survives — agave included. Pure spirits also can’t be glycemic-index tested in any meaningful way, since GI measures a blood sugar response to carbs, and straight spirits carry none.

The World Health Organization draws the same conclusion at a policy level: no alcohol type is safer than another, and a standard drink delivers roughly the same ethanol no matter what it’s distilled from.

A Note on Alcohol and GLP-1 Diets

Alcohol deserves care on a GLP-1 medication, regardless of which spirit you pick. It can lower blood sugar too far, and it can compound the nausea or GI side effects some people already experience. It also adds calories without any of the fullness or fiber your meals are working to provide. None of that rules out a drink at dinner. It just means you should talk with your doctor or pharmacist about alcohol and your specific medication. This post covers nutrition facts, not medical advice.

Why Mixers Wreck Low-Carb Tequila Drinks

Straight spirits are nearly identical: about 90–100 calories per 1.5 oz pour, 0g carbs, 0g sugar, whether you pour tequila, vodka, gin, or whiskey. The sugar problem in a cocktail almost never starts with the spirit. It starts with what surrounds it.

Drink component	Serving	Calories	Carbs / sugar
Tequila, vodka, gin, whiskey (straight)	1.5 oz	~90–100	0g
Triple sec / orange liqueur	1.5 oz	~150	~16g
Coffee or cream liqueur	1.5 oz	~150–175	15–17g
Bottled margarita mix	4 oz	~180	30g+
Cream of coconut	2 oz	~200	25g+
Regular soda / cola mixer	6 oz	~75	20g
Restaurant margarita (full recipe)	8 oz	300–500	30–40g
Piña colada	8–9 oz	500–650	60g+

A margarita’s sugar load comes from the triple sec and sour mix. A piña colada’s comes from cream of coconut. Pull the spirit out of either drink, and the calorie count barely moves.

Final Thoughts on Tequila Diet Myths

Tequila isn’t secretly bad for you, and it isn’t a health drink either. Nutritionally, it’s interchangeable with vodka, gin, and whiskey once mixers leave the picture. The viral tequila diet myths trace back to a mouse study about plant fiber, not tequila, and a rounded-down calorie count that doesn’t hold up. The real takeaway is simpler: if you’re watching sugar and carbs, the spirit matters less than what you pour around it. Skip the sweet mixer, keep the citrus and soda, and any of these five low-carb tequila drinks gets you through the night without the hidden sugar load.
