The keto diet is a low-carb, high-fat diet that aims to achieve a metabolic state of ketosis, where the body burns fat instead of carbohydrates for energy. This strict carbohydrate restriction means that many foods that are conventionally considered healthy, such as legumes, are off-limits. Legumes, including beans, soybeans, and peas, are typically high in carbohydrates and can disrupt ketosis if consumed in excess. While some legumes like peanuts and peanut butter are low enough in carbs for strict keto diets, most others like black beans, kidney beans, and chickpeas should be consumed in limited quantities or avoided altogether to maintain ketosis.

What You'll Learn

Legumes are high in carbohydrates
The ketogenic diet is a fat-rich, carbohydrate-poor diet. The body gets its energy from fats instead of carbohydrates, and enters a metabolic process called ketosis, which helps burn fat instead of carbs. Typically, people on a keto diet aim to eat upwards of 80% of their calories from fat and very few carbs. This means that most fruits, legumes, dairy, starchy vegetables, and whole grains are off the menu.
Legumes, such as beans and lentils, are high in carbohydrates. For example, black-eyed peas contain approximately 11 grams of carbs per cup, while chickpeas contain 19 grams of carbs per cup. Even half a cup of cooked black beans can contain about 13 grams of net carbs. Fava beans are also high in carbs and should be consumed in moderation on a low-carb diet. Cranberry beans, cowpeas, garbanzo beans, great northwest beans, lentils, mung beans, and soybeans are other types of legumes that should be consumed in limited quantities to allow for a restricted daily carb intake.
While legumes are a good source of protein, fiber, vitamins, and minerals, their carbohydrate content means that portion control is crucial. It is recommended to opt for low-carb varieties like black beans, green beans, and peanuts, and always monitor your daily carb intake to stay in ketosis.
It is worth noting that keto is not a one-size-fits-all diet, and working with a dietitian is important to ensure you are getting essential nutrients while maintaining ketosis.

They can be included in small amounts
The ketogenic diet is a low-carbohydrate, high-fat diet. The body enters a metabolic state known as ketosis, where fat is burned for energy instead of carbohydrates. Typically, the diet involves restricting carb intake to fewer than 50 grams per day. As a result, many foods that are conventionally considered healthy are not compatible with the keto diet.
Legumes, such as beans and lentils, are often considered off-limits on the keto diet due to their high carbohydrate content. For example, a half-cup serving of cooked black beans contains about 13 grams of net carbs. However, this does not mean that legumes need to be completely eliminated from the diet. Legumes can be included in small amounts as long as daily carb intake limits are not exceeded. For instance, black soybeans are a good alternative to higher-carb beans, with only one net carb per half-cup serving.
It is important to note that the keto diet is not a one-size-fits-all approach, and it can be challenging to meet nutritional needs while maintaining ketosis. Working with a dietitian is crucial to ensure essential nutrients are being consumed and to help create a plan that includes legumes. Additionally, those on the keto diet may be more susceptible to gastrointestinal issues due to the high fibre content of legumes.
Some legumes are lower in carbohydrates than others, making them better options for the keto diet. For example, peanuts and peanut butter can be included as long as portion sizes are controlled and no added sugars are present. Roasted soybeans are another low-carb, protein-rich option. Green beans are also mentioned as a keto-friendly legume.
In conclusion, while legumes are generally considered high in carbohydrates and off-limits on the keto diet, they can be included in small amounts, especially lower-carb varieties. It is important to monitor daily carb intake and make adjustments to stay within ketosis.

They are a good source of protein
Legumes are a diverse group of plants that includes beans, lentils, soybeans, chickpeas, peas, and peanuts. They are a good source of protein, offering a plant-based alternative to animal proteins. While they are typically high in protein, the exact amount varies depending on the type of legume and how it is prepared.
For example, boiled soybeans (or edamame) are an excellent source of protein, providing about 63% of the daily value (DV) per cup cooked. This is significantly higher than most other beans, which provide between 29% and 36% of the DV per cup cooked. Lentils, another legume, contain approximately 7 grams of protein per 80-gram serving. Chickpeas, black beans, and peas are also good sources of protein, offering a similar nutritional profile to other legumes.
Legumes are a valuable source of protein for those following a vegetarian or vegan diet, as they provide an easy and inexpensive way to increase protein intake. They are also a good option for those looking to boost their fibre and essential nutrient intake, as legumes are typically rich in both of these.
However, for those following a ketogenic diet, legumes may need to be limited or avoided due to their carbohydrate content. The keto diet is a low-carbohydrate, high-fat diet that aims to keep daily carbohydrate intake below 50 grams to maintain ketosis, the state in which the body burns fat instead of glucose for fuel. Many legumes are high in digestible carbohydrates, which can cause an individual to exceed their daily carb limit if consumed in excess. As such, portion control is essential when including legumes in a keto diet, and some varieties, such as black-eyed peas, chickpeas, and fava beans, may need to be avoided altogether.

They are rich in fibre and antioxidants
Legumes are rich in fibre and antioxidants, as well as protein and essential vitamins and minerals. However, they are also high in carbohydrates, which are restricted on the ketogenic diet.
The keto diet is a low-carbohydrate, high-fat diet that aims to put the body into a metabolic state known as ketosis, where it burns fat for fuel instead of carbohydrates. To stay in ketosis, keto dieters must restrict their daily carbohydrate intake to fewer than 50 grams of net carbs per day.
Legumes, such as beans, lentils, soybeans, chickpeas, peas, and peanuts, are a good source of fibre and antioxidants, but they also contain significant amounts of digestible carbohydrates. For example, a half-cup serving of prepared black beans contains about 13 grams of net carbs, and a one-cup serving of chickpeas contains 19 grams of carbs.
While legumes are not entirely off-limits on the keto diet, portion control is crucial. Some legumes, like black beans, green beans, peanuts, and black soybeans, are lower in carbs and can be included in moderation as part of a keto diet. However, overconsumption of legumes can quickly lead to exceeding the daily carb limit on keto, so it is important to monitor intake and choose low-carb legume options when possible.

There are low-carb legume options
Legumes are typically off-limits on the keto diet due to their high carbohydrate content. The keto diet is a low-carb, high-fat diet that aims to put the body into a metabolic state called ketosis, where it burns fat for fuel instead of carbohydrates. To achieve and maintain ketosis, it is recommended to restrict daily carb intake to 20 to 50 grams.
However, this does not mean that all legumes are completely off-limits on the keto diet. There are a few low-carb legume options that can be incorporated into a keto diet plan. Here are some examples:
- Peanuts and Peanut Butter: Natural peanut butter and peanuts are low enough in carbs for strict keto diets, as long as portion sizes are controlled.
- Soybeans: Roasted soybeans are a protein-rich, low-carb snack option. Soy products like tofu and tempeh are also keto-friendly and can be used as meat alternatives in plant-based diets. Black soybeans, in particular, are extremely high in fiber and can be used as an alternative to higher-carb beans in soups and chilis.
- Peas: While peas are legumes, they are fairly low in carbs and can be included in a keto diet.
- Lupini Beans: Lupini beans, also known as lupin beans, are commonly used in Mediterranean cuisine. They are high in fiber, with 11 grams per serving, bringing their net carb count down to just 1 gram. They can be used in recipes in place of other beans or legumes, and lupin flour is a popular keto baking option.
- Green Beans: Green beans are more like a non-starchy vegetable in terms of their nutritional profile and can be easily incorporated into a keto diet. They contain roughly 2 grams of net carbs per 1/2 cup serving.
- Mung Beans: Mung beans are commonly used in Asian cooking and are lower in carbs compared to other types of beans, but they may not be the best option for keto due to their carb content.
It is important to note that while these legumes are considered low-carb, portion sizes should still be monitored to ensure they fit within the daily carb limit for ketosis. Additionally, some people may experience digestive issues when consuming legumes due to their high fiber content.
