Short answer

No. The Harvard Nutrition Source lists beans, lentils, peanuts and all other legumes among the foods cut from every version of keto. 100 g of cooked carioca beans has 13.6 g of carbohydrate, 8.5 g of which is fiber.

How many carbs do beans have?

Source: TACO (NEPA/Unicamp), per 100 g; carbohydrate includes fiber.
Food Total carbohydrate (g) Fiber (g)
Beans, carioca, cooked 13.6 8.5
Beans, black, cooked 14.0 8.4
Black-eyed peas, cooked 13.5 7.5
Beans, jalo (yellow), cooked 16.5 13.9

What about the fiber in beans?

Beans are high in fiber, which is why some keto resources talk about subtracting it and using “net carbs.” Harvard notes that this is an unregulated term, created by the food industry, and that there is debate even among keto followers about this calculation. The same page mentions a question that is still open: whether a milder ketosis, with slightly more carbohydrate, could keep the effect on hunger and allow foods such as whole grains, legumes and fruits.

What to eat instead

For protein, keto lists name meat, poultry, pork, fish, eggs and tofu. The 7-day meal plan shows how to combine them with vegetables.

Talk to a doctor or dietitian before taking beans off your plate, especially if you have diabetes or another condition, take medication, or are pregnant or breastfeeding. For precautions to take before you start, see ketogenic diet risks and precautions.
