Plus, these zesty citrus fruits are packed with phytonutrients that can help keep you healthy and ward off diseases. So go ahead and squeeze some lemon into your life.

It's got that tangy, refreshing taste that everyone loves. But it's not just tasty—it's also packed with health benefits.

In this article, we'll take a closer look at the carb content of lemon juice, talk about its nutritional value, and see how it fits into different diets.

Carb Content of Lemon Juice

A serving of 24ml (a little under 5 tsp) of lemon juice only packs 1.2g of total carbs and 6 calories, made up of roughly the same amount of fiber and sugar.

It's important to note that lemon juice from the store or a lemon-flavored drink may have more carbs because of added sugars or other additives. Make sure to check the nutrition label to get the real scoop on the carb content.

Versatility of Lemons and Their Juice

Lemons are famous for giving a kick of flavor, a burst of freshness, and a tangy twist to beverages and dishes. They're the go-to citrus fruit that people use the most. Lemons also come in handy for fancy decorations and enhancing the taste of desserts. You can squeeze them to get the juice, slice them into wedges, or grate them to get that lemony zest.

This amazing fruit is packed with vitamin C and you can find them throughout the year. They're a must-have in your kitchen for making salad dressings, adding some zest to seafood recipes, infusing water with a refreshing taste, and so much more.

There are many different types of lemons out there. Most of them are bright yellow, but some have a bit of a greenish tint. Fun fact: one of the most popular kinds, the Meyer lemon, isn't actually a true lemon. It's a mix of a lemon and a mandarin or orange.

When you go to the store, the lemons you see are probably Eureka, Lisbon, or Bearss lemons. They're the ones that are grown in California, Florida, and Arizona.

You can usually find lemons in the grocery store all year long because  some growers harvest them year-round, but the best time to get them is in late winter to early spring or summer.

How Does Lemon Juice Fit into Different Diets? 

Lemon juice is often included in many diets because it tastes refreshing and has potential health benefits. One of these benefits is that it contains a relatively low amount of carbs. Now, let's dig into how lemon juice and its carb content play a role in different diets.

1. Low-Carb and Keto Diets

Lemon juice is totally cool to add to low-carb and keto diets, which are all about cutting back on carbs. A fluid ounce of lemon juice usually has around 1.2 to 1.5 grams of carbs, mostly from natural sugars. Since lemon juice is pretty low in carbs, you can enjoy it in moderation without messing up your carb limit.

2. Weight Loss Diets

Lemon juice is a popular addition to weight loss diets because it can help boost metabolism and improve digestion. The low amount of carbs in lemon juice makes it a great option for those following a calorie-restricted diet. Plus, it can be used to add a natural burst of flavor to water or other drinks without piling on extra calories or carbs. So, if you're looking to shed some pounds, consider adding a splash of lemon juice to your daily routine. It's an easy and tasty way to support your weight loss goals.

3. Diabetic Diets

If you have diabetes, it's important to keep an eye on how many carbs you eat to control your blood sugar levels. Lemon juice is okay to include in your diet because it doesn't have a lot of carbs. However, remember to think about the total amount of carbs in your meals and drinks, including any added sugars or mixers, to make sure your blood sugar stays steady.

4. Mediterranean Diets

The Mediterranean diet is all about eating lots of fresh fruits, veggies, whole grains, and good fats. Lemon juice is a popular ingredient in Mediterranean cooking because it adds a nice flavor to dishes and dressings. Even though it has some carbs, the Mediterranean diet is flexible enough to include lemon juice without breaking its rules.

5. Intermittent Fasting

If you're planning to try intermittent fasting, which involves specific periods of fasting and eating, having a bit of lemon juice during the fasting window may not hinder the benefits of the fast. But, keep in mind that even a small amount of calories can technically break the fast, so it's important to be mindful of what you consume.

6. Balanced Diets

Lemon juice is totally fine to add to your balanced diet without worrying about carbs. It tastes super refreshing and can even make you want to drink more water, which is essential for staying hydrated. Plus, lemon juice has loads of vitamin C and antioxidants that are really good for your overall health. So go ahead and enjoy that lemony goodness.


Although lemon juice itself is low in carbs, some lemon-flavored products like lemonades or lemon desserts can have more carbs because of added sugars or other ingredients. Therefore, it's a good idea to read the labels or make your own versions using fresh lemon juice to have control over the carb content.
