Understanding Carbs in Fruit
When assessing which fruit has the lowest carbs in it, it's crucial to understand the concept of net carbs. Net carbs are calculated by subtracting the grams of fiber from the total carbohydrates. Since fiber is a type of carbohydrate that your body cannot digest, it doesn't raise blood sugar levels and is often excluded from the carb count on low-carb diets like keto. This is why some fruits that appear to have moderate total carbs, like certain berries, can actually be quite low in net carbs due to their high fiber content.
The Top Contenders for Lowest Carb Fruits
While most people associate fruits with high sugar and carb levels, there are several delicious exceptions. The lowest-carb fruit is arguably the avocado, a versatile addition to any diet. Other non-traditional fruits, such as olives and tomatoes, also feature very low carb counts. For more conventional fruity flavors, berries are your best bet.
The All-Star: Avocado
Avocado is a standout fruit for anyone watching their carb intake. Botanically a large single-seeded berry, it is exceptionally low in net carbs and high in healthy fats, which promote satiety and heart health. A 100-gram serving of avocado contains approximately 8.5g of total carbohydrates but a significant 6.7g of fiber, leaving a net carb count of just 1.8g. Its creamy texture and mild flavor make it an excellent addition to salads, smoothies, or enjoyed on its own.
Berries: Low in Sugar, High in Flavor
Berries are a favorite among low-carb dieters due to their flavor, versatility, and high antioxidant content. Different berries offer varying levels of carbs, but most are considerably lower than tropical or starchy fruits.
Raspberries: A 100-gram serving has around 12g of total carbs and a notable 6.5g of fiber, resulting in a net carb count of 5.5g. Blackberries: These contain roughly 10g of total carbs per 100g, with 5.3g of fiber, for a net carb count of 4.7g. Strawberries: With 100g providing about 7.7g of total carbs and 2g of fiber, the net carb count is 5.7g.
Melons: Hydrating and Refreshing
Melons, with their high water content, are another excellent low-carb choice, especially during warmer months. Water content dilutes the carbohydrate density, making them a hydrating and lower-calorie snack.
Watermelon: This quintessential summer fruit is one of the lowest-carb options by total weight, containing just 7.55g of carbohydrates per 100g. Cantaloupe: A 100-gram serving has 8.16g of carbohydrates, providing essential vitamins A and C.
The Unconventional Fruits
Some foods we commonly think of as vegetables are actually fruits and have surprisingly low carb counts.
- Tomatoes: These are technically berries and are exceptionally low in carbs, with just 3.9g of total carbs per 100g. They are a great source of lycopene, an antioxidant linked to various health benefits.
- Olives: Another fruit, olives are prized for their healthy fats and low carb content. A cup of green olives contains just over 5g of carbs.
- Rhubarb: This plant is legally considered a fruit in the US and offers a very low 3g of carbs per half-cup serving.

How to Incorporate Low-Carb Fruits into Your Diet
Integrating these fruits can be simple and delicious. For a breakfast boost, add a handful of raspberries to Greek yogurt. Use sliced avocado and tomatoes to top a salad or make a satisfying, low-carb avocado toast on keto-friendly bread. Fresh berries can be enjoyed with a dollop of unsweetened whipped cream for a guilt-free dessert. Lemon or lime juice, which are also very low in carbs, can be used to add flavor to water or marinades without increasing your carb count. For those following a ketogenic diet, it is important to track net carbs carefully, as even small portions can add up.
