Navigating Beans on a Keto Diet
For many following a ketogenic diet, the sight of beans is often met with caution. This is because most traditional beans are starchy and high in carbohydrates, making them unsuitable for the restrictive carb limits of keto. A typical keto diet restricts net carbs to a very low daily intake, often between 20 and 50 grams. A single serving of beans like black beans or pinto beans can easily consume a significant portion of this daily allowance.
However, it's a misconception that all beans are off-limits. Several types of beans and legumes are surprisingly low in net carbs and can be included in moderation. The secret is to understand which ones are acceptable and how to prepare them to maximize their health benefits while staying in ketosis.
The Top Keto-Friendly Beans
Green Beans Often treated as a vegetable rather than a bean, green beans (also known as string beans) are one of the most accessible and keto-friendly options. A half-cup serving of cooked green beans contains approximately 2-3 grams of net carbs, making them an excellent choice for a low-carb side dish. They are also a good source of vitamins A and C, and provide a decent amount of fiber to aid digestion. Green beans are incredibly versatile and can be sautéed with garlic, roasted with almonds, or added to casseroles to boost nutrition and flavor without compromising your macros.
Black Soybeans Black soybeans are a game-changer for keto dieters who miss the texture and taste of traditional beans. With just 2 grams of net carbs per half-cup serving, they are a fantastic substitute for higher-carb beans in dishes like chili, dips, and refried beans. Black soybeans are also an excellent source of plant-based protein and fiber, making them highly satiating. They can be found in canned form or cooked from dried beans. When using canned versions, always check the label for added sugars or starches that could increase the carb count.
Edamame (Green Soybeans) Another viable option in moderation is edamame, or immature green soybeans. A half-cup of shelled edamame contains around 6-7 grams of net carbs. While this is higher than green beans or black soybeans, it can still fit into a keto meal plan if portioned carefully. Edamame offers a complete protein source, providing all nine essential amino acids. They make a great snack or addition to salads and stir-fries.
Lupini Beans Lupini beans are a lesser-known but highly keto-friendly legume. They are very low in carbohydrates and high in protein and fiber, making them a great high-protein snack. They typically require a long soaking process to remove bitterness if purchased dried, but pre-cooked and jarred options are readily available in many stores. They can be enjoyed as a snack, added to salads, or pureed into a hummus-like dip.
Beans to Avoid and Why
While the low-carb options above are safe, most other beans are too starchy for a standard keto diet. It is crucial to be aware of which varieties to steer clear of. Common beans that should be avoided or severely limited include:
- Black Beans: Approximately 13g net carbs per half-cup.
- Pinto Beans: Around 15g net carbs per half-cup.
- Kidney Beans: Approximately 11-16g net carbs per half-cup.
- Lima Beans: A staggering 20g net carbs per half-cup.
- Chickpeas (Garbanzo Beans): Roughly 16g net carbs per half-cup.
Even in small amounts, these beans can quickly use up a large portion of your daily carb allowance, making it difficult to maintain a state of ketosis. For more in-depth information on carb counts for various beans, Healthline provides a comprehensive resource.
Comparison of Keto-Friendly vs. High-Carb Beans
To better understand the differences, here is a comparison table of the net carb counts for a half-cup serving of cooked beans:
| Bean Type | Net Carbs (g) | Keto Friendliness | Best Use on Keto |
|---|---|---|---|
| Green Beans | 2-3 | Very High | Side dishes, salads, casseroles |
| Black Soybeans | ~2 | Very High | Soups, chilis, refried beans, dips |
| Shelled Edamame | 6-7 | Moderate | Snacks, salads, stir-fries (in moderation) |
| Lupini Beans | Very Low | Very High | Snacking, salads |
| Black Beans | ~13 | Very Low | Best to avoid; occasional, small portions in multi-serving recipes |
| Pinto Beans | ~15 | Very Low | Best to avoid |
| Lima Beans | ~20 | Very Low | Best to avoid |
Tips for Incorporating Keto-Friendly Beans
- Prioritize Portion Control: Even with low-carb options like black soybeans and edamame, moderation is key. A half-cup serving is a standard guideline to ensure you don't exceed your daily carb limit.
- Rinse Canned Beans: Canned beans, particularly black soybeans, should be rinsed thoroughly to wash away any added sodium or starches that could affect the nutritional profile.
- Check Labels Diligently: When buying any canned or packaged bean product, always check the nutrition facts. Look for "net carbs" and be mindful of added sugars, especially with products like baked beans.
- Try Bean-Less Alternatives: If you are highly sensitive to carbs or simply want to avoid legumes altogether, numerous alternatives can replicate the texture of beans. These include mushrooms, eggplant, and ground meats.
- Use as a Garnish or in Recipes: For higher-carb beans like black or kidney beans, a clever approach is to use them in recipes with many other ingredients and high serving sizes. For instance, adding a small amount to a large, multi-serving chili recipe can provide flavor and texture without a significant carb impact per serving.
Conclusion
While a true keto diet requires careful monitoring of carbohydrate intake, it does not mean all beans are off the menu. By focusing on the lowest net-carb options, such as green beans and black soybeans, you can still enjoy the nutritional benefits of legumes, including fiber and protein, while staying in ketosis. Always prioritize portion control and be vigilant with nutrition labels, especially with processed or canned products. With smart choices and careful planning, you can successfully integrate healthy, keto-friendly beans into your low-carb lifestyle.

Are lentils okay for keto?
No, lentils are typically too high in carbohydrates to be a regular part of a keto diet. While they are healthy, a small serving can quickly use up your daily carb allowance.
How can I make keto refried beans?
You can make keto-friendly refried beans by using black soybeans as the main ingredient. Recipes often call for blending cooked black soybeans with seasonings, bacon, and lime juice for a delicious, low-carb alternative.
What are the main health benefits of keto-friendly beans?
