Short answer
In most versions of the keto diet, no. Raw Palmer mango has 19.4 g of carbs per 100 g, 97% of a 20 g daily limit. Like almost all fruit, it only fits if you can make room for it in your daily carb count.
How many carbs does mango have?
| Food | Total carbs (g) | Fiber (g) |
|---|---|---|
| Palmer mango, raw | 19.4 | 1.6 |
| Haden mango, raw | 16.7 | 1.6 |
| Tommy Atkins mango, raw | 12.8 | 2.1 |
| Frozen mango pulp | 12.5 | 1.1 |
| Formosa papaya, raw | 11.6 | 1.8 |
| Hawaiian papaya, raw | 10.4 | 1.0 |
| Strawberry, raw | 6.8 | 1.7 |
The variety makes a big difference: Tommy Atkins has 12.8 g per 100 g, a third less than Palmer. If the frozen pulp (12.5 g) is blended into juice, the Harvard Nutrition Source rule applies: fruit juices are out of every version of keto.
What about papaya?
Papaya follows the same rule as other fruit. Raw Formosa papaya has 11.6 g of carbs per 100 g and Hawaiian papaya 10.4 g: less than mango, but more than strawberries (6.8 g), one of the berries keto lists allow in small portions.
If you have diabetes, take medication, or are pregnant or breastfeeding, check with a health professional before cutting out fruit. The food list shows what usually fits. For precautions before you start, see ketogenic diet risks and precautions.
