Carrots are moderate in carbs compared to other vegetables. A medium raw carrot contains about 6 grams of total carbohydrates, and 100 grams (roughly two small carrots) has 9 grams of carbs with 2.7 grams of fiber, leaving around 6.3 grams of net carbs. That puts carrots higher than many popular low-carb vegetables, but low enough to fit into most reduced-carb eating plans if you watch your portions.
How Carrots Compare to Other Vegetables
Carrots don’t make most “best low-carb vegetables” lists, and the reason is straightforward: other common vegetables deliver fewer carbs per serving. One cup of raw zucchini has 4 grams of carbs (3 grams net), and one cup of raw broccoli has 6 grams of carbs (4 grams net). A cup of raw spinach contains just 1 gram of carbs. A cup of chopped carrots (about 122 grams) lands at roughly 11 grams of total carbs and 9 grams of net carbs, putting it well above those alternatives.
That said, carrots are still far lower in carbs than starchy vegetables like potatoes, corn, or sweet potatoes, which can deliver 25 to 30 grams of net carbs per cup. Carrots sit in a middle zone: not the leanest option, but nowhere near the starchy end of the spectrum.
Why Carrots Taste Sweeter Than You’d Expect
Carrots get their noticeable sweetness from natural sugars that make up roughly 3.5 to 10.7 percent of the fresh root’s weight, depending on the variety. Sucrose is the dominant sugar, accounting for about 57 percent of the total sugar content. Glucose makes up around 25 percent, and fructose the remaining 18 percent. This sugar profile is why carrots taste sweeter than broccoli or cauliflower, and it’s the main reason low-carb dieters sometimes wonder whether they should avoid them.
Carrots on a Keto Diet
Keto typically limits net carbs to 25 grams or fewer per day. A full cup of carrots uses up about 9 grams of net carbs, which is more than a third of that daily budget in a single serving. That doesn’t mean carrots are off-limits on keto, but it does mean portion control matters. A handful of carrot sticks (roughly half a cup or a single medium carrot) keeps your net carb hit closer to 3 to 4 grams, which is much easier to work into a keto day alongside other vegetables.
If you’re following a more relaxed low-carb approach, say 50 to 100 grams of net carbs per day, carrots fit comfortably without much planning at all.
Does Cooking Change the Carb Count?
Cooking method has a small effect on carbohydrate density. Raw carrots contain about 7.6 grams of carbs per 100 grams. Steamed carrots are nearly identical at 7.3 grams. Boiled carrots actually drop slightly, to around 5.7 to 6.3 grams per 100 grams depending on how long they cook, because some sugars leach into the cooking water.
The more meaningful change is in how your body responds. Boiled carrots have a glycemic index of about 33, which is considered low. Raw carrots score even lower. A low glycemic index means the sugars are released into your bloodstream gradually rather than causing a sharp spike, and the glycemic load of a typical half-cup serving of boiled carrots is just 1, which is negligible. So even though carrots contain natural sugars, they don’t hit your blood sugar the way processed carbs or starchy foods do.
Practical Portion Guide
Your carb budget determines how freely you can eat carrots:
- Keto (under 25g net carbs): Stick to one medium carrot or about half a cup chopped, giving you roughly 3 to 4 grams of net carbs.
- Moderate low-carb (50 to 100g net carbs): A full cup of carrots at 9 grams of net carbs fits easily.
- General healthy eating: Carrots are not a high-carb food by any standard measure. Eat them freely.
Pairing carrots with a fat or protein source, like hummus, guacamole, or cheese, slows digestion and blunts any minor blood sugar response. This is a useful habit on keto or any low-carb plan where you’re trying to keep energy levels steady throughout the day.
