What Beans Are Allowed on Keto Diet? Your Low-Carb Guide

4 min read

According to the USDA, a cup of green beans contains only about 4 grams of net carbs, proving not all beans are off-limits for low-carb eating. Many dieters wonder what beans are allowed on keto diet, given that most legumes are famously high in carbohydrates. While the keto diet typically restricts carb intake, certain varieties can be enjoyed in moderation.

Quick Summary

Most traditional beans are too high in carbohydrates for a standard ketogenic diet. However, low-carb options like green beans and black soybeans can be enjoyed in moderation, with careful attention to portion sizes and tracking net carbs.

Key Points

  • Green Beans: Very low in net carbs (~4g per cup), making them a versatile and safe vegetable for a keto diet.

  • Black Soybeans: A great low-carb alternative for traditional beans, typically containing only 1-2g net carbs per half-cup, but check brand labels as this can vary.

  • Moderation is Essential: Even keto-friendly beans should be eaten in controlled portions to ensure you stay within your daily net carb limits.

  • Avoid High-Carb Beans: Steer clear of traditional varieties like kidney, pinto, and chickpeas, as they are too high in net carbs for a ketogenic diet.

  • Embrace Alternatives: Consider using substitutes like mushrooms, eggplant, or ground meat in recipes to mimic the texture of beans.

  • Understand Net Carbs: The net carb count, calculated by subtracting fiber from total carbs, is the key factor in determining if a food is keto-friendly.

The ketogenic diet focuses on restricting carbohydrate intake to induce a metabolic state known as ketosis. This means that many traditionally healthy foods, including most beans, must be limited or avoided due to their high carb counts. Yet, a few select legume varieties offer a lower net carb profile, allowing them to be incorporated into a keto diet with mindful planning.

The Few Bean Varieties That Fit a Keto Lifestyle

While the answer to "what beans are allowed on keto diet?" is often perceived as 'none', there are a handful of exceptions. These beans are naturally lower in carbohydrates and higher in fiber, resulting in a low net carb count that won't disrupt ketosis when consumed in moderation.

Green Beans

Often prepared as a vegetable, green beans are one of the most keto-friendly options available. A cup of green beans typically contains around 4 grams of net carbs, making them an excellent choice for a side dish. They offer a crunchy texture and can be prepared in numerous ways, such as sautéed with garlic, roasted with parmesan, or mixed into a hearty casserole.

Black Soybeans

For those who miss traditional black beans, black soybeans are a fantastic low-carb alternative. A half-cup serving of canned black soybeans typically contains around 2 grams of net carbs. This makes them a perfect substitute in chili, soups, or even as a base for low-carb 'refried beans'. It is important to note that net carb counts can vary between brands, so always check the nutrition label.

Edamame

Immature green soybeans, known as edamame, are a high-protein, low-carb snack that can be enjoyed on keto. A half-cup serving of shelled edamame contains approximately 3-4 grams of net carbs. They are a great appetizer or addition to salads, offering a satisfying texture and mild, nutty flavor.

Lupini Beans

Lupini beans are another low-carb legume that can be incorporated into a keto diet. These beans are high in fiber and protein, with some preparations resulting in as little as 1 gram of net carbs per serving. They are often sold brined in jars or as dried beans and can be enjoyed as a snack or added to other dishes.

High-Carb Beans to Avoid

The vast majority of beans and legumes are too high in starch and net carbohydrates for a standard ketogenic diet. To maintain ketosis, it is best to avoid these varieties.

High-Carb Bean List:

  • Kidney Beans: Frequently used in chili and stews, but too high in carbs.
  • Pinto Beans: A common staple, but with a high net carb count.
  • Chickpeas (Garbanzo Beans): The base for hummus and roasted snacks, but not keto-friendly.
  • Navy Beans: Often used in baked bean recipes, which are also high in sugar.
  • Lentils: While nutritious, their carb count is too high for keto.

Navigating Portions and Alternatives

Even with keto-friendly beans, portion control is essential. Incorporating small amounts is key to staying within your daily carb limits, which for most keto followers is 20–50 grams of net carbs.

Net Carbs Calculation

Remember that net carbs are calculated by subtracting the grams of fiber from the total carbohydrates. The high fiber content in beans is what allows some varieties to be suitable for keto, as fiber is not digested in the same way as other carbohydrates.

Comparing Bean Varieties

Bean Type Serving Size Total Carbs (g) Fiber (g) Net Carbs (g) Keto-Friendly?
Green Beans 1 cup, cooked 7 3.4 ~3.6 Yes
Black Soybeans ½ cup, canned 8 7 ~1 Yes (Brand Dependent)
Edamame (shelled) ½ cup 8.9 2.2 ~6.7 Moderate
Kidney Beans ½ cup, cooked 20 5.7 ~14.3 No
Pinto Beans ½ cup, cooked 22 7.5 ~14.5 No

*Note: Nutritional information can vary, so always consult the nutrition label of your specific product. Net carbs for black soybeans can differ significantly by brand.

Keto-Friendly Bean Alternatives

For recipes like chili or hearty soups where beans are typically a star ingredient, several alternatives can achieve a similar texture and richness without the carbs:

  • Ground Meat: Ground beef, turkey, or pork can replace beans in chili recipes.
  • Mushrooms: Chopped mushrooms, especially cremini, can add a meaty texture to soups and stews.
  • Eggplant: Diced eggplant can be used in cooked dishes as a low-carb, high-fiber substitute.
  • Hemp Hearts: These can provide a nutty flavor and added protein to salads and sides.
  • Cauliflower Rice: For a very low-carb filler, riced cauliflower can bulk up dishes.

Preparation Tips for Keto Beans

When cooking and eating low-carb beans, proper preparation can improve both flavor and digestion. Start with small portions to allow your body to adjust to the increased fiber. Pairing your beans with healthy fats like olive oil or avocado can also enhance satiety. Always cook beans thoroughly, as proper cooking neutralizes lectins and makes them safe for consumption.

Conclusion: Finding the Right Balance for Your Keto Diet

The question of what beans are allowed on keto diet has a nuanced answer. While most high-carb varieties are best avoided, specific low-carb options like green beans and black soybeans can be included in your meal plan with proper portioning. By understanding net carbs and exploring keto-friendly alternatives, you can enjoy some of the nutritional benefits of legumes while successfully adhering to a ketogenic lifestyle. Remember that moderation is the ultimate key to success. For more information on navigating low-carb diets, a great resource can be found at Healthline.
