Short answer
In most versions of the ketogenic diet, no. Like almost all fruit, mandarins only fit if they stay within your daily carb limit, and the variety makes a difference: 100 g of raw Rio mandarin has 9.3 g of carbs; Murcott has 14.9 g, about 60% more.
How many carbs are in mandarins?
The fruit goes by different names depending on the region (mandarin, tangerine). In TACO, the Brazilian reference table, it appears as Rio mandarin, Murcott mandarin, and Ponkan tangerine.
| Food | Total carbs (g) | Fiber (g) |
|---|---|---|
| Rio mandarin, raw | 9.3 | 2.7 |
| Ponkan tangerine, raw | 9.6 | 0.9 |
| Murcott mandarin, raw | 14.9 | 3.1 |
| Ponkan tangerine juice | 8.8 | trace |
| Strawberry, raw | 6.8 | 1.7 |
In numbers: 100 g of Rio mandarin is 19% of a 50 g daily limit and 47% of a 20 g limit. With Murcott, the same portion reaches 75% of the 20 g limit.
What about the juice?
It’s out. The Harvard Nutrition Source lists all fruit juices among the foods cut on keto. Ponkan tangerine juice has 8.8 g of carbs per 100 g and only trace amounts of fiber.
Which fruits keto lists allow
According to Harvard’s summary, berries in small portions are the exception; other fruits only fit if you count them toward your carb limit. Raw strawberries have 6.8 g per 100 g. Oranges follow the same rule as mandarins.
If you have diabetes, take medication for blood sugar or blood pressure, or are pregnant or breastfeeding, talk to a doctor before cutting out or counting fruit. For precautions before you start, see ketogenic diet risks and precautions.
