Lentils are a nutritious and budget-friendly source of plant-based protein. However, if you're following a ketogenic (keto) diet, you might be wondering whether lentils can fit into your eating plan. The keto diet is characterized by high fat intake, moderate protein consumption, and very low carbohydrate intake. This article explores the compatibility of lentils with a keto diet, considering their nutritional profile and the principles of ketosis.
Understanding the Keto Diet
A ketogenic diet revolves around sustaining ketosis, a metabolic state where your body burns fat instead of carbohydrates for energy. This shift occurs when carbohydrate intake is drastically reduced, typically to 5-10% of your daily calorie intake, while protein comprises 15-20%. By maintaining ketosis, individuals may experience benefits such as rapid weight loss and improved blood sugar control. Some studies also suggest that it may reduce seizures in individuals with epilepsy.
To achieve and maintain ketosis, the keto diet restricts foods high in carbs, such as starchy vegetables, grains, and legumes. While the keto diet may offer short-term benefits, more research is needed to fully understand its long-term effects on overall health.
Lentils and Their Nutritional Profile
Lentils belong to the legume family, which also includes beans, soy, and chickpeas. They are a staple in many diets worldwide, known for being kid-friendly and packed with beneficial nutrients. They are a great source of protein, containing all essential amino acids. Lentils also provide a wide range of bioavailable micronutrients required for general health and well-being. The nutrients found in red lentils, including essential fatty acids, play a role in cognitive development and function. Additionally, lentils are high in fiber.
However, legumes are generally avoided on a strict keto diet due to their high carb content. One cup (180 grams) of cooked lentils provides 36 grams of carbs. Even after subtracting the 14 grams of fiber, the net carb content is 22 grams. Considering that a typical keto diet restricts net carbs to 25-50 grams per day, consuming a cup of lentils can take up a significant portion of your daily carb allowance.

The Verdict: Lentils on Keto
Given their high net carb content, lentils may not be the most suitable choice for those following a strict keto diet. Consuming even a moderate serving of lentils can easily exceed the daily carb limit, potentially disrupting ketosis. As a result, those following a strict keto diet will want to restrict their intake of lentils.
However, it's not an all-or-nothing situation. Smaller portion sizes, such as 1/2 cup (90 grams) or 1/4 cup (45 grams) of cooked lentils, can potentially fit into a keto diet, depending on your individual carb allowance and the other foods you consume that day.
Potential Benefits of Including Lentils (in Moderation)
One benefit of occasionally including lentils in your diet is their impressive nutritional profile. They provide several important vitamins and minerals, including potassium, magnesium, folate, phosphorus, and iron, which can be difficult to obtain adequately on a keto diet.
Keto-Friendly Alternatives
Despite the potential benefits, it's important to remember that there are other ways to obtain these essential nutrients while staying within the guidelines of a keto diet. Non-starchy vegetables, low-sugar fruits, and seeds are excellent alternatives that are lower in carbs and provide essential nutrients for a well-rounded keto diet. Leafy greens, mushrooms, broccoli, almonds, and even edamame are lower in carbs than lentils, and they provide essential nutrients for a well-rounded keto diet.
Incorporating Lentils into a Keto Diet: Tips and Considerations
If you're determined to include lentils in your keto diet, here are some tips to minimize their impact on ketosis:

Lemony Red Lentil Stew Recipe (Keto-Friendly Adaptation)
Ingredients:
- 1 tablespoon olive oil (or water for an oil-free option)

Instructions (Instant Pot):
- Set your Instant Pot to sauté. Add the olive oil (or water) and onions. Cook until the onions are soft.
- Add in the garlic and spices (poultry spice, cumin, and paprika). Cook for another minute to release their flavors.
- Add in the red lentils and stir to coat with the spices.
- Add in the vegetable broth, kale, and diced carrots.
- Close the lid and set the Instant Pot to the 'Bean' setting for 15 minutes. Ensure the vent is set to 'Sealing' to build pressure.
- Once the time is up, vent the Instant Pot.
- Add in the lemon juice (along with the spinach if using it). Close the lid and let it sit for 2 minutes to wilt the spinach.
- Serve with some sliced avocado or over steamed rice (if not strictly keto).
Instructions (Stovetop):
- Over medium-high heat, add your olive oil to a large pot. Add in the onions and cook until soft.
- Add in the garlic and spices and cook for another minute.

Tips for Picky Eaters:
- Adjust the spices to suit your children's taste.
- Serve the stew over rice or with a side of keto-friendly bread.
- Involve your kids in the cooking process.
Additional Considerations
- Lectin Content: Lentils contain lectins, which are proteins that can interfere with nutrient absorption in some individuals. Soaking lentils before cooking can help reduce their lectin content.
- Allergies: If you're allergic to chickpeas or other legumes, you may also be allergic to lentils. Consult with your doctor or an allergist to determine your allergy status.
- Kid-Friendly Options: To make lentil soup more appealing to children, consider adjusting the spices, serving it with a side of bread or rice, or involving them in the cooking process.
