When it comes to embarking on a ketogenic diet, one of the common questions that arise pertains to the keto-friendliness of various food items.

Today, we turn our focus to a fragrant herb that is a staple in many cuisines around the world: Is Lemon Grass Keto-Friendly? As we'll explore in this article, Lemon Grass is not only compatible with a keto diet due to its low net carbohydrate content but it also brings along potential health benefits and exciting culinary uses.

Whether you're a seasoned pro at keto or just starting out, this comprehensive guide will help you understand how Lemon Grass can fit into your ketogenic lifestyle.


  • Yes, Lemon Grass is Keto-Friendly due to its low net carbohydrate content, but that's not all it has to offer.
  • Lemon Grass provides potential health benefits such as aiding digestion, reducing inflammation, and may even enhance mood.
  • There are many creative ways to incorporate Lemon Grass into your keto diet, from teas to curries and stir-fries.

Is Lemon Grass Keto-Friendly?

Let's get straight to the point: Is Lemon Grass keto-friendly? Yes, it is.

When we discuss whether a food item fits into a ketogenic diet, we generally focus on its carbohydrate content. As you may know, the ketogenic diet is a low-carb, high-fat diet, so any food to be considered 'keto-friendly' must have a relatively low carb content.

Now, let's take a closer look at Lemon Grass. For every 5 grams of Lemon Grass, there are only 1.27 grams of net carbs. That's relatively low compared to many other herbs and spices. It's this low net carb content that makes Lemon Grass a friend to those following a ketogenic lifestyle.

It's worth noting that net carbs are what you're left with when you subtract a food's fiber content from its total carbohydrates. In the world of keto, we care about net carbs because your body can't fully digest fiber. As a result, fiber doesn't impact your blood sugar levels the way other carbs do, and it doesn't throw your body out of ketosis.

Just to give a bit more context, the daily carb limit for a typical ketogenic diet is around 20-50 grams. So, the relatively small 1.27 grams of net carbs that Lemon Grass contributes can easily fit within this limit, even if you were to use it liberally in your cooking.

Can Lemon Grass be Incorporated into a Strict Keto Diet?

We've established that Lemon Grass is keto-friendly - but how does it fare on a strict ketogenic diet? Even more so than in a standard ketogenic diet, those adhering to a strict keto diet need to keep meticulous track of their carb intake. So where does Lemon Grass come in?

With its low net carb content of 1.27g per 5g, Lemon Grass can indeed be accommodated in a strict keto diet. However, like all things, it must be consumed in moderation. You see, every gram of carbohydrate counts in a ketogenic diet - particularly a strict one. So, while Lemon Grass is low in carbs, these carbs still contribute to your total daily intake.

That is why it's crucial to maintain a balance and keep track of the amount of Lemon Grass you consume along with other dietary components. It's all about ensuring that you're staying within your daily carb limit, which for a strict keto diet is typically at the lower end of the 20-50g range.

Now, when it comes to tracking your carb intake, there are several handy tools available. Nutrient tracking apps can be your best friend here. They allow you to log everything you eat and drink, give you an easy way to check the nutritional breakdown of various foods, and most importantly, help you keep track of your daily carb consumption.

Delving into the Carbohydrate Content of Lemon Grass

Let's take a closer look at the carbohydrate content in Lemon Grass that makes it a keto-compatible food item. As we've mentioned, Lemon Grass contains 1.27g of net carbs per 5g. But what does this mean, and why is it important for those of us following a ketogenic diet?

Net carbs are what you're left with when you subtract the fiber content of a food from its total carbohydrate content. This distinction is important because unlike other carbs, fiber is a type of carbohydrate that your body can't fully digest. As a result, it doesn’t affect your blood sugar levels the same way that other carbohydrates do and doesn't interfere with ketosis – the metabolic state at the heart of the ketogenic diet.

So, when we talk about the 1.27g of net carbs in Lemon Grass, we're talking about the carbs that matter when it comes to maintaining ketosis.

Now, let's translate this into real-world serving sizes. If you were to add a tablespoon of chopped Lemon Grass (about 6g) to your soup or stir-fry, you'd be adding approximately 1.5g of net carbs to your meal. If you used a whole stalk of Lemon Grass (about 36g) to infuse a pot of soup or broth and then removed it before eating, you'd be adding negligible carbs to the entire dish since the actual amount of Lemon Grass consumed would be minimal.

Health Implications of Lemon Grass on a Keto Diet

Incorporating Lemon Grass into a ketogenic diet does more than just keep your carb count in check. This aromatic herb also offers a variety of health benefits that can complement the advantages of a keto lifestyle.

Firstly, Lemon Grass is known for its potential digestive health benefits. It has been used traditionally in many cultures to soothe stomach ailments and ease digestion. While on a ketogenic diet, a well-functioning digestive system is crucial to ensure optimal absorption of the nutrients from high-fat, moderate-protein foods.

In addition to aiding digestion, Lemon Grass has anti-inflammatory properties. Inflammation is a natural response by the body to protect itself from harm, but chronic inflammation can lead to various health issues. A ketogenic diet is often praised for its potential anti-inflammatory effects, largely credited to the reduction in sugar intake. Adding Lemon Grass to your keto meals may amplify these benefits.

Furthermore, research suggests that Lemon Grass may have mood-enhancing properties. The encouraging scent of Lemon Grass is believed to help reduce anxiety and stress, promoting a sense of well-being. And while a keto diet is not a cure for mental health conditions, many followers of the diet report increased energy levels and improved mood.

Lastly, Lemon Grass is a source of several essential vitamins and minerals, including vitamin C and iron. While these nutrients are not provided in high amounts, every bit contributes to your overall nutrient intake.

Incorporating Lemon Grass into Your Keto Meal Plan

You've learned about the keto-friendly nature of Lemon Grass and its potential health benefits. Now, how can you incorporate this fragrant herb into your ketogenic meal plan?

Lemon Grass is a versatile ingredient that can fit nicely into a variety of dishes. It's commonly used in soups, curries, stir-fries, and even teas. Just remember, like with any ingredient on a ketogenic diet, it's all about moderation and tracking your intake.

One of the simplest ways to use Lemon Grass is in a homemade tea. Just simmer sliced Lemon Grass stalks in water, strain, and enjoy a warm, comforting cup of tea. For added flavor, you could infuse it with other keto-friendly ingredients like ginger or a dash of heavy cream.

Next, you might try incorporating Lemon Grass into your main dishes. It pairs well with coconut milk, another keto staple, in a fragrant keto-friendly curry. Sauté your choice of low-carb vegetables and protein in coconut oil, add in your chopped Lemon Grass, pour over some full-fat coconut milk, and let it all simmer together for a dish brimming with flavor.

Lemon Grass is also fantastic in stir-fries. Combine it with your favorite keto-friendly veggies, like bell peppers and broccoli, and a source of protein like chicken or tofu. Just make sure to chop the Lemon Grass finely or remove the larger pieces before serving, as it can be tough to chew.

Lastly, let's not forget about marinades. A simple marinade of Lemon Grass, garlic, chili, and lime can transform your grilled meats or seafood into a tantalizing meal.

Keto-Compatible Alternatives for Lemon Grass

Even though Lemon Grass is completely keto-compatible, it may not always be readily available, or some individuals might prefer a different flavor profile. Fortunately, there are a few keto-friendly alternatives that can be used as effective substitutes in various recipes.

One such alternative is Ginger. Like Lemon Grass, it's low in carbs, with only 1.77 grams of net carbs per 5 grams. It brings a spicy, warm flavor that can work well in soups, stir-fries, or teas, much like Lemon Grass. For example, you could use ginger instead of Lemon Grass in your homemade keto-friendly tea or your coconut milk curry.

Another versatile and keto-friendly substitute is Kaffir Lime Leaves. These leaves pack a potent, citrusy aroma that can add depth to your keto dishes. They contain around 1.39 grams of net carbs per 5 grams, making them as keto-friendly as Lemon Grass. Kaffir Lime Leaves can be used whole, finely chopped, or even as a zest in your keto-friendly curries, stir-fries, or marinades.

Lastly, you may consider using Lemons. The zest and juice of lemons are often used to mimic the citrusy overtones of Lemon Grass. Bear in mind, though, that lemons contain slightly more carbs, with about 2.5 grams of net carbs per medium-sized lemon. So be sure to adjust your carb count accordingly. Lemon zest or juice can be used in most dishes where Lemon Grass is used, for a different but equally refreshing flavor.
