Short answer
In most versions of the ketogenic diet, no. Orange is excluded from permitted fruits, and fruit juice is cut in all of them. If you decide to eat it, it must fit within your daily carbohydrate allowance: 100 g of raw Pera orange has 8.9 g of carbohydrate, equivalent to 18% of a 50 g limit and 45% of a 20 g limit.
How much carbohydrate does orange have?
| Food | Total carbohydrate (g) | Fiber (g) |
|---|---|---|
| Orange, Pera variety, raw | 8.9 | 0.8 |
| Orange, navel (Bahia), raw | 11.5 | 1.1 |
| Orange, Lima variety, raw | 11.5 | 1.8 |
| Orange, Pera variety, juice | 7.6 | trace |
| Strawberry, raw | 6.8 | 1.7 |
Why orange is excluded
The keto summaries from the Harvard Nutrition Source leave out almost all fruits; they only count if included within the carbohydrate limit. Berries are the exception, in small portions: raw strawberry has 6.8 g of carbohydrate per 100 g, versus 8.9 g for raw Pera orange and 11.5 g for raw navel (Bahia) orange.
And orange juice?
It is excluded: all fruit juices are cut on keto. Pera orange juice has 7.6 g of carbohydrate per 100 g and only trace fiber.
If you have diabetes, take medication, are pregnant or breastfeeding, talk to a doctor or dietitian before cutting fruit. To build meals, see the list of permitted foods. Precautions before starting are in risks and cautions of the ketogenic diet.
