Are Lentils Keto-Friendly?

Lentils are relatively high in carbs; therefore they don’t make the best option for low carb diets like Keto.  However, on more liberal low-carb diets, you may be able to incorporate a moderate amount of lentils.

Any kind of lentils are high starch nutrients, therefore these legumes are not typically eaten on a Ketogenic diet.  Granted, they may be a healthy food, but the high carb counts won’t help your body stay in ketosis.  Avoid these legumes on the keto diet or strictly limit them to a ¼ cup serving if following a more liberal low carb diet.

How Many Carbs Are In Lentils?

A 100 gram serving of lentils contains 20 grams of carbs.  A 1 cup serving of lentils contains 40 grams of carbs, 16 of which are fiber, totalling 24 grams of net carbs.

Similar to lentils, legumes like peas and beans, as well as grains like corn and quinoa are all fairly high in carbs – so these foods should be limited on a ketogenic diet.

How Many Calories Are In Lentils?

There are 116 calories in a 100 gram serving of lentils.  A 1 cup serving of lentils contains 230 calories. 

Because lentils are low in calories, they make a great food choice if you are embarking on a weight-loss journey and following a diet other than Keto. Because lentils are virtually fat-free and high in fiber, they tend to keep you feeling satiated for longer periods of time.

Lentils can be added to almost any dish to bulk up the plant-based protein and fiber; such as, stews, soups, and salads. Adding lentils to your meals may even help reduce cravings and prevent overeating.

What are Lentils?

Lentils are an edible legume. They come from a bushy annual plant known for its small round seeds. The crop reaches heights of around 40 centimetres and grows pods that typically contain two seeds in each. 

Origin of Lentils

Lentils are thought to have originated in the East and Mediterranean areas.  They have been a popular food source of our ancestors since ancient times. In fact, they’re one of the earliest domesticated crop known to man!

Health Benefits of Lentils      

Lentils are low in fat, high in protein, folate, phosphorus and iron.  They are high in B vitamins, iron, magnesium, potassium and zinc. They’re also an excellent source of plant-based protein.

Lentils are high in fiber to support a healthy digestive tract and the growth of good gut bacteria. Eating lentils can help ease constipation and improve gut function.  The soluble fiber in lentils also regulates your cholesterol and blood sugar levels.

Additionally, lentils contain a variety of important plant compounds known as phytochemicals.  These compounds help the body fight off chronic illnesses, such as heart disease and type 2 diabetes.

Types of Lentils

Brown: These are the most popular type and are earthy in flavour and retain their firmness while cooking.  Brown lentils make a great addition to stews and soups.

Green: These can vary in size and are usually a more cost efficient alternative to using Puy lentils in recipes.

Yellow and Red: These lentils are split and cook quickly. They have a slightly sweet and nutty flavor.

Puy: These lentils hail from the French region of Le Puy.  Puy lentils have a peppery taste.  They look similar to green lentils, except they’re considerably smaller in size.  Puy lentils are also known as French lentils.  These small lentils hold their shape better after cooking.

Beluga: These lentils are so tiny and black, they almost resemble caviar. They make a great addition to salads.

How to Prepare Lentils

Lentils are simple to prepare and can be used in a variety of dishes.  When using dry lentils, pour the beans into a strainer and run cold water over them for about a minute, tossing them to ensure they are rinsed well throughout. Add a half cup of dry lentils to 1 cup of boiling water. Turn the heat down to low and simmer for about a half hour, until tender.

If you are going to use lentils in a salad, you may only want to cook them for only 15 minutes to give them a firmer texture and make sure they aren’t too mushy.
