Lentils are edible seeds from the legume family, which also includes beans, chickpeas, and peanuts. They are a popular food worldwide due to their availability, long shelf life, and nutritional value. However, their high carbohydrate content makes them unsuitable for a strict keto diet, which requires keeping total carb intake below 50 grams per day. As a cup of cooked lentils contains about 22-36 grams of net carbs, they can account for up to 50% of the daily carb allowance. Therefore, those on a strict keto diet are advised to avoid lentils altogether. However, those on less strict versions of the keto diet can include small portions of lentils in moderation, such as adding a quarter cup of lentils to a soup or salad.

Lentils are high in carbs, so they don't fit a strict keto diet
Lentils are a cheap and nutritious edible seed, making them a staple in the diets of students and those on a budget. They are rich in nutrients, including protein, fibre, iron, magnesium, potassium, and vitamin B6. However, they are also high in carbohydrates, with a cup of cooked lentils providing 36 grams of carbs. This is a problem for those on a keto diet, as this eating pattern is very low in carbs, with a daily limit of 20-50 grams of net carbs.
As a result, lentils are not typically considered keto-friendly, and those following a strict keto diet should avoid them altogether. A cup of lentils would use up half of the daily carb allowance, so it is not a good option for those looking to keep their carb intake to a minimum. However, this does not mean that lentils need to be completely eliminated from a keto diet. They can be consumed in small quantities, such as a quarter cup of lentils sprinkled over a salad, or added to a soup or burger patty.
For those on a less strict version of the keto diet, lentils can be included in slightly larger quantities. For example, those with a carb limit of 50 grams could eat half a cup of lentils in a day, combined with another keto-friendly dish. Those following a cyclical keto diet can also enjoy lentil dishes more freely, as they can eat legumes on their designated high-carb days.
If you are on a strict keto diet and looking for alternatives to lentils, you could try leafy greens such as spinach, kale, and cabbage, or mushrooms, broccoli, almonds, and edamame, which are all lower in carbs.

Small portions of lentils can be eaten on keto in moderation
Lentils are edible seeds that are part of the legume family. They are rich in nutrients, including protein, fiber, iron, magnesium, potassium, and vitamin B6. They are also very high in carbohydrates, with one cup of cooked lentils providing 36 grams of carbs. This is equivalent to 22 grams of net carbs after subtracting the fiber content. Due to their high carb content, lentils are generally not recommended for a strict keto diet, which typically restricts total carb intake to 20-50 grams per day.
However, small portions of lentils can be eaten on keto in moderation. For example, instead of adding a full cup of lentils to a soup recipe, you could add just 1/4 cup and substitute the remaining portion with low-carb alternatives like edamame, hemp hearts, cauliflower, or shirataki rice. This reduces the carb intake from the dish while still allowing you to enjoy the taste and health benefits of lentils. It is important to note that the keto diet aims for 75% fats, 20% proteins, and only 5% net carbs, so lentils should be consumed in small quantities to avoid exceeding the recommended carb limit.
When incorporating lentils into your keto diet, it is crucial to consider your daily carb intake and physical activity level. Lentils can be a good source of protein and keep hunger pangs in control for a long time, making them a suitable option for weight loss plans. Additionally, they are low in calories, providing around 230 calories per 100 grams of cooked lentils.
It is worth mentioning that there are alternative food options that are more keto-friendly and provide similar nutritional benefits. Leafy greens, such as spinach, kale, and cabbage, have a low carb content and can be consumed freely while staying in ketosis. Mushrooms, broccoli, almonds, and edamame are also lower in carbs than lentils and can be excellent substitutes. These alternatives ensure that you obtain essential nutrients while adhering to the keto diet's strict carb restrictions.
In summary, small portions of lentils can be incorporated into a keto diet in moderation. However, it is important to be mindful of your overall carb intake and combine lentils with other keto-friendly dishes to maintain ketosis. Additionally, there are alternative food options that may better align with the keto diet's requirements while still providing a diverse range of nutrients.

Lentils are nutritious and have health benefits, but they're not keto-friendly
Lentils are edible seeds, rich in nutrients like protein, fiber, iron, magnesium, potassium, and vitamin B6. They are also a good source of folate, making them a nutritious food with several health benefits. However, lentils are not keto-friendly due to their high carbohydrate content.
The keto diet is high in fat, moderate in protein, and very low in carbohydrates, typically restricting total carb intake to 20-50 grams per day. This low-carb intake is necessary for the body to sustain ketosis, a metabolic state in which the body burns fat instead of carbohydrates for fuel.
Lentils are part of the legume family, which also includes beans, soy, chickpeas, and peanuts. While legumes are excellent sources of protein and fiber, they are generally too high in carbohydrates to align with a strict keto diet. A single cup of cooked lentils (approximately 180 grams) contains 36 grams of carbohydrates, yielding 22 grams of net carbs after subtracting the fiber content. This amount of net carbs equates to at least 50% of the daily carb allowance on a keto diet, making lentils impractical for those aiming to keep their carb intake very low.
However, it is important to note that not all keto diets are the same, and some variations may allow for more flexibility. For example, those following a less strict version of the keto diet or cyclical keto, which includes high-carb days, may be able to incorporate small portions of lentils into their diet without compromising ketosis. Additionally, lentils can be added to keto-friendly dishes in moderate amounts, such as soups or burgers, to enhance their nutritional profile without significantly impacting carb intake.
While lentils offer nutritional benefits, they are not inherently keto-friendly due to their high carbohydrate content. For strict keto dieters aiming to maintain ketosis, it is advisable to limit or avoid lentil consumption and opt for lower-carb alternatives, such as leafy greens, mushrooms, or broccoli.

Keto-friendly alternatives to lentils include leafy greens, broccoli, and mushrooms
Lentils are edible seeds, rich in nutrients and protein, and are often used in soups and salads. However, they are also high in carbohydrates, which makes them unsuitable for a strict keto diet. The keto diet is high in fat, very low in carbs, and moderate in protein. This eating pattern is necessary for the body to sustain ketosis, a state in which the body burns fat instead of carbs for fuel.
A cup of cooked lentils (180-198 grams) contains 22-24.2 grams of net carbs, which is almost half of the recommended daily carb intake of 50 grams for keto dieters. Therefore, those on a strict keto diet are advised to avoid lentils altogether.
However, if you are flexible and not on a strict keto diet, you can eat lentils in moderation. Smaller portion sizes, such as a quarter or half a cup, can fit into a keto diet, depending on what else you consume that day.
For those on a strict keto diet, alternatives to lentils include leafy greens, broccoli, and mushrooms, which are lower in carbs and provide essential nutrients for a well-rounded keto diet. Leafy greens like spinach, kale, and cabbage are low in carbs, so you can eat as much as you want while staying in ketosis. For example, a cup of spinach only contains three grams of net carbs. Broccoli is another keto-friendly option, with four grams of carbs per serving. Mushrooms are a tasty alternative to lentils, with one serving containing just two grams of net carbs.

Cyclical keto allows legumes on high-carb days, but portion sizes are key
The keto diet is high in fat, very low in carbs, and moderate in protein. This eating pattern is necessary for the body to sustain ketosis, a state in which your body burns fat instead of carbs for fuel.
Lentils are a type of legume, a category that also includes beans, soy, and chickpeas. They are high in both carbs and protein, so it’s not a good option for strict keto dieters who want to keep their carb intake to a minimum. A cup of cooked lentils provides 36 grams of carbs. Even when you subtract the fibre content, it still yields 22 grams of net carbs. As net carbs are generally restricted to just 20–50 grams per day, a cup of cooked lentils would use up at least 50% of your carb allowance for the day.
However, if you are flexible, you can eat lentils in moderation. For example, instead of adding a cup of lentils to your soup, you could add a quarter of a cup and swap out the remaining portion for edamame, hemp hearts, cauliflower, or lupini beans.
If you are following cyclical keto, you can enjoy lentil dishes more freely as you do not have a limit on your carb intake on high-carb days. However, it is important to be careful with portion sizes. Portion sizes for most legumes are half a cup cooked, and you should measure the amount you’re eating so you can log your carb intake accurately.
