Guacamole is low in carbs. A standard two-tablespoon serving contains about 3 grams of total carbohydrates, and roughly 2 of those grams come from fiber. That leaves under 1 gram of net carbs per serving, making guacamole one of the most low-carb-friendly dips you can eat.
Carb Breakdown per Serving
In a two-tablespoon (30-gram) serving of guacamole, you’re looking at approximately 3 grams of total carbohydrates and 2 grams of dietary fiber. Net carbs, the number that matters for blood sugar and most low-carb diets, comes out to roughly 1 gram. For context, most strict keto diets allow 20 to 50 grams of net carbs per day, so even a generous portion of guacamole barely makes a dent.
The fat content is more notable than the carbs. That same serving delivers about 5 grams of fat, mostly the monounsaturated kind found in olive oil. Guacamole is calorie-dense relative to its volume, but those calories come from fat and fiber rather than carbohydrates.
Why Avocados Keep the Carbs So Low
Avocado is the reason guacamole sits so far down the carb scale. A whole medium avocado contains about 13 grams of total carbohydrates, but 10 of those grams are fiber, according to Harvard’s School of Public Health. That fiber-to-carb ratio is unusually high for a fruit. Most of the remaining calories come from heart-healthy monounsaturated fat, with 22 grams of total fat per avocado.
Because fiber passes through your digestive system without being absorbed as sugar, it doesn’t raise blood glucose the way starches and sugars do. This is why avocado-based foods consistently land in the “low glycemic” category. Research has noted that avocado’s combination of low carbohydrates, high fiber, and healthy fats may help lower the overall glycemic impact of a meal when included alongside higher-carb foods.
How Guacamole Compares to Other Dips
The carb difference between guacamole and other popular dips is dramatic. Per two-tablespoon serving:
- Guacamole: about 2.7 grams of carbs
- Hummus: about 14 grams of carbs
Hummus has more than five times the carbohydrates. It does contain more fiber (6.3 grams versus 2 grams), but the net carb count is still significantly higher. Bean-based dips fall into a similar range as hummus, since legumes are naturally starchy. Cheese-based dips like queso tend to be lower in carbs than hummus but still carry more than guacamole, depending on added ingredients like flour thickeners.
If you’re choosing a dip specifically for its carb count, guacamole is hard to beat among common options.
What Adds Carbs to Store-Bought Guacamole
The numbers above apply to basic guacamole made primarily from avocado. Store-bought versions can vary. Some brands add fillers like corn starch, tomato paste, or sugar to extend shelf life or adjust texture, and these bump the carb count upward. A few commercial guacamoles contain as much as 5 to 6 grams of carbs per serving instead of the expected 3.
Check the nutrition label if the carb count matters to you. The ingredient list should be short: avocado, lime juice, salt, onion, cilantro, maybe jalapeño. If you see starches, added sugars, or ingredients you wouldn’t use at home, the carb profile will be higher than homemade.
Homemade guacamole is simple to control. The add-ins that are traditional (lime, onion, cilantro, tomato, chili) contribute minimal carbohydrates in the small amounts typically used.
Portion Size and Practical Carb Counts
Two tablespoons is the standard “serving size” on nutrition labels, but most people eat more than that in a sitting. If you’re scooping guacamole with chips or spooning it onto a burrito bowl, you might easily consume a quarter cup (4 tablespoons) or more. Even at double the serving size, you’re still only looking at about 2 grams of net carbs from the guacamole itself.
The bigger carb consideration is usually what you’re eating the guacamole with. Tortilla chips can add 15 to 20 grams of carbs per handful. Swapping chips for raw vegetables like bell pepper strips, cucumber slices, or celery keeps the entire snack in low-carb territory. Using guacamole as a topping on eggs, grilled chicken, or salads adds flavor and healthy fat without meaningful carbohydrate impact.
For people following keto, low-carb, or blood sugar management plans, guacamole is one of the safest dips to include regularly. Its combination of fiber, healthy fat, and negligible net carbs makes it a practical choice without needing to restrict portions the way you would with grain or legume-based alternatives.
