How many carbs are in an avocado?
One whole avocado (136g, no skin or seed) has 11.8g of carbs and 2.6g of net carbs. Almost all the carbohydrate is fiber, which makes avocado one of the lowest net-carb whole foods available.
Carbs by portion
| Portion | Total carbs | Fiber | Net carbs |
|---|---|---|---|
| 1 whole avocado (136g) | 11.8g | 9.2g | 2.5g |
| 1 cup, pureed (230g) | 19.9g | 15.6g | 4.2g |
| 100 grams | 8.6g | 6.8g | 1.8g |
Net carbs
One whole avocado has just 2.6g of net carbs, calculated as total carbs (11.8g) minus fiber (9.2g). The fiber content is unusually high for a fruit and is the reason avocado barely moves blood sugar for most people. Half an avocado has about 1.3g of net carbs. See the net carbs guide for when to count net versus total carbs.
For diabetes
An avocado's total carb count of 11.8g per fruit is manageable, but most diabetes care teams dose on total carbs, not net. If you eat a whole fruit, count the full 11.8g. Half an avocado is about 5.9g total. The high fat and fiber content genuinely slows gastric emptying, so the carbs arrive more gradually than the same amount from bread or juice. Avocado pairs well with higher-carb foods because the fat buffers the glucose rise. See the diabetes carb-counting guide for how to apply this.
Keto and low carb
Half an avocado has about 1.3g of net carbs. A whole fruit is 2.6g. On a 20 to 30g daily net carb budget, avocado fits easily and is one of the few fruits that genuinely belongs in a keto plan. The fat content (21g per fruit) also makes it a practical calorie source when carbs are restricted.
Good to know
California avocados (the Hass variety) run smaller and denser than Florida avocados. Florida avocados are larger but carry more water and slightly fewer calories per gram of flesh, though both are nutritionally similar per 100g. The numbers here are for California-type avocados per USDA SR Legacy data. Once cut, avocado oxidizes quickly. Storing the cut half with the pit in place and pressing plastic wrap directly onto the flesh slows browning. Lime juice also helps but does not materially change the carb count.

How many carbs are in an avocado?
One whole avocado (136g of flesh, no skin or seed) has about 11.8g of total carbohydrate and 9.2g of fiber, leaving 2.6g of net carbs.
How many net carbs are in an avocado?
A whole avocado has about 2.6g of net carbs. Half an avocado has roughly 1.3g of net carbs. The high fiber (9.2g per fruit) accounts for most of the carbohydrate.
Is avocado keto?
Yes. A whole avocado has only 2.6g of net carbs, well under a typical keto daily budget of 20 to 30g. It is also high in fat, which supports ketosis.
Can diabetics eat avocado?
Yes. Count the total carbs (11.8g per fruit, 5.9g per half) for dosing purposes. The fat and fiber content slow the carb absorption, which helps reduce post-meal spikes compared with other 12g-carb foods.
Does avocado have a glycemic index?
Avocado does not have a well-established glycemic index value. GI testing requires foods with enough carbohydrate to produce a measurable glucose response, and avocado's carb content is too low to generate reliable GI data.
