How many carbs are in strawberries?
Strawberries has 12.8 g of total carbs per 1 cup sliced (166 g) — about 9.5 g net carbs after 3.3 g of fiber. That's 7.7 g of carbs per 100 g, roughly 5% of the 275 g Daily Value.

If you’re counting carbs and craving fruit, strawberries are the easy answer. A 1-cup sliced serving (166 g) carries only about 12.8 g of total carbohydrate — low to begin with for a fruit — and roughly 3.3 g of that is fiber. Subtract the fiber and you land at about 9.5 g of net carbs, the number that actually matters for keto and low-carb tracking. Per 100 g the totals are 7.7 g carbs, 2 g fiber, leaving about 5.7 g net. There’s only about 8.1 g of natural sugar in the whole cup, which is the real headline: strawberries are the lowest-sugar common berry.
Why the net carbs stay low
Net carbs are simply total carbs minus fiber, and strawberries win on both halves of that equation. Unlike a banana or a grape, they don’t start from a high carb base — a full cup is under 13 g total. On top of that, they bring a meaningful 3.3 g of fiber, the indigestible part that passes through without turning into blood sugar. The combination is what makes them the opposite of the sugary fruits: where tropical fruit packs dense, digestible sugar, strawberries deliver sweetness, water, vitamin C and fiber for very little usable carbohydrate. That modest sugar load, cushioned by fiber, is also why a normal portion barely nudges blood sugar.
The keto and low-carb verdict
Strawberries are genuinely keto-friendly — one of the few fruits that earns the label. At ~9.5 g net carbs per cup, they fit even a strict 20 g keto day as a portioned treat, and on a moderate low-carb or diabetic-friendly plan they’re an easy yes. They’re the go-to berry for anyone avoiding sugar: a bowl of strawberries costs a fraction of the carbs of an apple or a banana, with the fiber and the low total doing the work. Keep the portion honest and they’re about as safe as fresh fruit gets.
Strawberries are a fruit you can enjoy on almost any plan, but they’re not a protein source — if you want that side of the picture, see protein in strawberries. And for any packaged or frozen version with added sugar, read the label’s own carb and fiber lines, since net carbs depend on both.
Frequently Asked Questions
How many carbs are in a cup of strawberries?
About 12.8 g of total carbohydrate in a 1-cup sliced serving (166 g), which is 7.7 g per 100 g (USDA FDC 167762). That's low for a fruit — roughly 3.3 g of it is fiber, so the number that counts for low-carb eating is lower still.
What are the net carbs in strawberries?
Roughly 9.5 g net carbs per cup — total carbs (~12.8 g) minus the ~3.3 g of fiber. Net carbs are low here for two reasons: strawberries are a low-total-carb fruit to begin with, and they carry a useful amount of fiber on top. The result is one of the most keto-friendly fruits you can pick.
Are strawberries keto or low-carb?
Yes, within reason. At ~9.5 g net carbs per cup, strawberries fit a strict 20 g keto day as a portioned treat and slot easily into a moderate low-carb plan. They're the go-to keto fruit alongside the other berries — a handful is far safer than a banana or an apple.
Do strawberries have a lot of sugar?
Less than most fruit. A cup has about 8.1 g of natural sugar (4.9 g per 100 g) — strawberries are the lowest-sugar common berry and well below grapes, bananas or mango. Paired with their fiber and water content, that modest sugar load is why they barely move blood sugar in normal portions.
Do strawberries have fewer carbs than bananas?
Far fewer. A cup of strawberries is ~12.8 g total carbs and ~9.5 g net; a medium banana is roughly 27 g of carbs with most of it digestible sugar and starch. For the same sweet hit, strawberries cost a fraction of the carbohydrate — which is exactly why they're the low-carb fruit of choice.
