Short answer
In most versions, no. Grapes are among the fruits that only fit if you can make room for them in your daily carb count, and they aren’t one of the lighter options: 100 g of raw Italia grapes has 13.6 g of carbohydrate, the equivalent of 27% of a 50 g limit and 68% of a 20 g limit.
How many carbs are in grapes?
| Food | Total carbohydrate (g) | Fiber (g) |
|---|---|---|
| Italia grapes, raw | 13.6 | 0.9 |
| Rubi grapes, raw | 12.7 | 0.9 |
| Grape juice concentrate, bottled | 14.7 | 0.2 |
| Strawberry, raw | 6.8 | 1.7 |
Rubi is close to Italia, at 12.7 g. Bottled grape juice concentrate has 14.7 g per 100 g and almost no fiber (0.2 g); according to the Harvard Nutrition Source, all fruit juices are out on keto.
What about raisins?
Drying grapes concentrates their sugar. In the U.S. Department of Agriculture (USDA) database, 100 g of dark raisins has 79.3 g of carbohydrate. For details, see raisins on the ketogenic diet.
If you’re craving fruit
Berries, in small portions, are the exception in the keto lists summarized by Harvard. Raw strawberries have 6.8 g of carbohydrate per 100 g, half as much as Italia grapes.
If you have diabetes, take medication, or are pregnant or breastfeeding, work out with a health professional how to handle fruit in your diet. It’s also worth reading about the risks and precautions of the ketogenic diet.
