Finding the right fruits to fit your low-carb lifestyle can be challenging while following a ketogenic diet. Many fruits are high in sugars and carbohydrates, making them unsuitable for keto. However, there are several delicious and nutritious low-carb fruits that can be enjoyed without kicking your body out of ketosis. Let’s explore which low-carb fruits are best for your keto diet.
What Makes a Fruit Keto-Friendly
A fruit is considered keto-friendly if it has a low carbohydrate content, allowing you to stay within the daily carb limit typically recommended for ketogenic diets, which is usually around 20-50 grams of net carbs per day. Net carbs are calculated by subtracting fiber from total carbohydrates, as fiber does not raise blood sugar levels.
One advantage of keto-friendly fruits is that they provide essential vitamins, minerals, and antioxidants without spiking your blood sugar. This is crucial for maintaining ketosis and reaping the benefits of the keto diet, such as improved energy levels, mental clarity, and weight loss.
Top Low-Carb Fruits for Your Keto Diet
Several fruits fit well into a ketogenic diet due to their low carbohydrate content. These include avocados, berries, and certain tropical and citrus fruits. Each of these options offers unique flavors and nutritional benefits while keeping your net carb intake low.
Keep in mind that portion control is key when incorporating these fruits into your diet. Even low-carb fruits can add up if consumed in large quantities, so it’s important to enjoy them in moderation to stay within your daily carb limit.
Avocados: The Perfect Keto Fruit
Avocados are often hailed as the perfect keto fruit. They are incredibly low in carbs and packed with healthy fats, making them an ideal choice for those on a ketogenic diet. A 100-gram serving of avocado contains only about 8.5 grams of carbohydrates, with 6.7 grams of that being fiber, resulting in just 1.8 grams of net carbs.
A big plus of avocados is their versatility. They can be used in salads, smoothies, or even as a spread on keto-friendly bread. Additionally, avocados are rich in essential nutrients such as potassium, vitamin K, and folate, which support overall health and well-being.
Berries: Are They Really Keto?
Berries can be a bit tricky on a keto diet, but some varieties are indeed keto-friendly. Raspberries, strawberries, and blackberries are among the best options due to their relatively low carbohydrate content. For example, a 100-gram serving of raspberries contains about 12 grams of carbs and 6.5 grams of fiber, resulting in roughly 5.5 grams of net carbs.
Note that while blueberries are often considered a healthy fruit, they are higher in carbs compared to other berries and should be consumed in smaller quantities on a keto diet.

“Strawberries are considered a low-carb and keto-friendly fruit, with around 11.7 carbs and 3 grams of fiber per 1-cup of halved berries (a 152-gram serving),” according to a 2021 study published in the Journal of Nutrients. The study suggests that eating strawberries daily could help promote better blood vessel functioning and protect against the risk of heart attack (Huang et al., 2021).
Tropical Low-Carb Fruits
While many tropical fruits are high in sugars and carbs, there are a few that can be enjoyed in moderation on a keto diet. Examples include coconut and star fruit. Coconut meat is low in carbs and high in healthy fats, making it an excellent addition to your keto meals. One cup of shredded coconut meat contains about 12 grams of carbs and 7 grams of fiber, resulting in 5 grams of net carbs.
Star fruit, or carambola, is another tropical fruit that is relatively low in carbs. A 100-gram serving of star fruit contains about 6 grams of carbs and 3 grams of fiber, resulting in only 3 grams of net carbs. This makes it a refreshing and exotic option for those on a keto diet.
Citrus Fruits on Keto
Citrus fruits like lemons and limes are great for adding flavor to your dishes without adding significant carbs. A whole lemon contains about 6 grams of carbs and 1.8 grams of fiber, resulting in 4.2 grams of net carbs. Lemons and limes can be used in a variety of ways, from flavoring water to adding zest to your meals.
Keep in mind that other citrus fruits like oranges and grapefruits are higher in carbs and should be consumed sparingly. Using lemon or lime juice as a flavor enhancer is a great way to enjoy the benefits of citrus without overloading on carbs.
Lesser-Known Keto Fruits
In addition to the more common low-carb fruits, there are several lesser-known options that can be included in a keto diet. These include fruits like olives and tomatoes. While often thought of as vegetables, both olives and tomatoes are technically fruits and are low in carbs.
Olives are a great source of healthy fats and contain about 3 grams of carbs per 100 grams, with 1 gram of fiber, resulting in 2 grams of net carbs. Tomatoes, particularly cherry tomatoes, are also low in carbs, with a 100-gram serving containing about 3 grams of net carbs. These fruits can add variety and flavor to your keto meals.

Fruits to Avoid on a Keto Diet
While there are several low-carb fruits suitable for a keto diet, many fruits should be avoided due to their high carbohydrate content. These include bananas, apples, and grapes, which can quickly exceed your daily carb limit and disrupt ketosis.
Note that dried fruits and fruit juices are particularly high in sugars and carbs, making them unsuitable for a keto diet. Instead, opt for fresh, low-carb fruits and be mindful of portion sizes to stay on track with your keto goals.
