What Are Yellow Lentils?
Yellow lentils, also known as toor dal or moong dal in Indian cuisine, are a type of pulse from the legume family. They are small, lens-shaped edible seeds popular in many parts of the world, especially in soups, stews, and curries. They are cherished for their earthy flavor, versatility, and ease of cooking, as they do not require pre-soaking. While valued for their nutritional profile, it is crucial to examine their carbohydrate content to determine their suitability for low-carb diets.
The High-Carb Profile of Yellow Lentils
For those monitoring their carbohydrate intake, the carb count of yellow lentils is a key factor. A typical cup of cooked lentils (approx. 180g) contains a significant amount of carbs.
Total vs. Net Carbs
Understanding the difference between total and net carbs is essential for low-carb and ketogenic diets. Net carbs are the carbohydrates that your body can fully digest and use for energy. They are calculated by subtracting the grams of dietary fiber from the total carbohydrate count.
- Total Carbohydrates: Around 40 grams per cooked cup.
- Dietary Fiber: About 16 grams per cooked cup.
- Net Carbs: Approximately 24 grams per cooked cup.
For a strict ketogenic diet that limits net carbs to 25–50 grams per day, a single cup of cooked yellow lentils could consume a significant portion or even exceed the entire daily allowance. This places them firmly outside the category of low-carb foods.
Yellow Lentils on a Keto Diet
The ketogenic diet's primary goal is to shift the body's metabolism into a state of ketosis, where it burns fat for fuel instead of glucose derived from carbohydrates. This requires a very low daily carbohydrate intake.
-
Incompatible with Strict Keto: A strict keto diet typically restricts net carb intake to 25 grams or less per day. Since one serving of yellow lentils contains over 20 grams of net carbs, it is largely incompatible with this dietary plan. Including lentils would make it extremely difficult to remain in ketosis.
-
Moderate Low-Carb Diets: For individuals on a more moderate low-carb plan, smaller portions of yellow lentils may be incorporated with careful planning. For example, a quarter or half-cup serving, which contains significantly fewer net carbs, could be used as an addition to meals, provided other food choices for the day are also low in carbohydrates.
Nutritional Powerhouse: Beyond the Carbs
Despite their high carbohydrate count, it is important not to dismiss the nutritional benefits of yellow lentils. They are packed with health-promoting nutrients, which is why they remain a staple in many balanced diets.
- Rich in Protein: Lentils are an excellent source of plant-based protein, with approximately 18 grams per cooked cup. This makes them a valuable food for vegetarians and vegans.
- Excellent Source of Fiber: The high fiber content is a major health benefit, promoting digestive health, managing appetite, and stabilizing blood sugar levels.
- Packed with Minerals: Yellow lentils are a good source of essential minerals, including iron, folate, potassium, and magnesium.
- Low Glycemic Index: Due to their high fiber and complex carbohydrates, lentils have a low glycemic index, meaning they cause blood sugar to rise gradually rather than spiking it.
Comparison: Yellow Lentils vs. Low-Carb Legume Alternatives
If you are following a strict low-carb or keto diet but want to incorporate some legumes, here is a comparison of yellow lentils with some lower-carb alternatives. Values are approximate per cooked cup.
| Legume | Total Carbs (g) | Fiber (g) | Net Carbs (g) |
|---|---|---|---|
| Yellow Lentils | ~40 | ~16 | ~24 |
| Soybeans | ~17 | ~10 | ~7 |
| Lupini Beans | ~18 | ~6 | ~12 |
| Edamame | ~14 | ~8 | ~6 |
Benefits of Including Lentils in a Balanced Diet
For those on a diet that allows for their carbohydrate content, lentils offer numerous health advantages:
- Weight Management: The high protein and fiber in lentils contribute to a feeling of fullness and satiety, which can help manage calorie intake and aid in weight loss.
- Heart Health: Lentils can help lower LDL ('bad') cholesterol levels, reducing the risk of cardiovascular disease.
- Blood Sugar Regulation: Their low glycemic index and fiber content make them beneficial for stabilizing blood sugar, which is particularly helpful for managing diabetes.

How to Incorporate Lentils on a Modified Low-Carb Plan
For those following a more flexible low-carb plan, portion control is key. Instead of using lentils as a primary component, consider them as a flavor or texture accent.
- Use as a Garnish: Sprinkle a small amount of cooked lentils over a salad or roasted vegetables.
- Blend into Soups: Add a small quantity to vegetable-based soups to increase fiber and protein without drastically increasing carbs.
- Mix with Low-Carb Vegetables: Combine a small portion of lentils with a large serving of non-starchy vegetables like cauliflower or leafy greens.
Conclusion
In summary, yellow lentils are not a low-carb food, with a high total carbohydrate and net carbohydrate count that makes them unsuitable for strict ketogenic diets. However, they are a highly nutritious food, rich in protein, fiber, and essential minerals, offering significant health benefits like improved heart health and weight management. For those on moderate low-carb diets, they can be included in small, controlled portions. The key is to be mindful of serving sizes and balance them with other low-carb food choices to stay within your daily carbohydrate limits.
