Fruits To Avoid During Low Carb Diet

Low-carb diets have surged in popularity due to their potential health benefits, including weight loss, improved blood sugar control, and better energy levels. By reducing carbohydrates and increasing protein and fat intake, individuals aim to change their metabolism from relying on glucose to utilizing fats for energy. However, one challenge is that many healthy foods, including fruits, contain natural sugars that can hinder low-carb progress. This article will explore fruits that should be avoided or limited during a low-carb diet and offer advice on alternatives and ways to enjoy fruit without compromising your diet goals.

Understanding Carbohydrates in Fruits

Fruits contain different types of natural sugars, primarily fructose, glucose, and sucrose. While these natural sugars provide a quick energy source, they can quickly add up, leading to a higher carbohydrate intake than desired on a low-carb diet.

Glycemic Index and Load: The glycemic index (GI) measures how much a food raises blood sugar levels compared to pure glucose. Fruits with a high glycemic index cause a rapid spike in blood sugar, which is generally undesirable in low-carb diets. Glycemic load (GL) takes into account the serving size, offering a more comprehensive understanding of how a specific amount of food impacts blood sugar.

Importance of Portion Control: Even low-GI fruits can become problematic if consumed in large quantities. Understanding serving sizes and carb counts in different fruits helps maintain a low-carb diet more effectively.

Fruits to Avoid on a Low-Carb Diet

High-Sugar Fruits

These fruits contain higher amounts of natural sugars and are best avoided or limited on a low-carb diet.

  • Bananas: Bananas are rich in potassium, vitamins, and dietary fiber, making them a healthy choice for most people. However, a medium banana contains around 27 grams of carbs, which can quickly consume your daily carb allowance. Instead, opt for berries or other low-carb fruits in smoothies and snacks.
  • Grapes: Grapes are packed with vitamins and antioxidants but have a high glycemic index and carb content. A cup of grapes contains around 27 grams of carbs, making them less suitable for a low-carb diet. Replace them with lower-carb options like strawberries or raspberries.
  • Mangoes: Known for their sweetness, mangoes are a favorite tropical fruit but pack about 25 grams of carbs per cup. They also have a high glycemic index, meaning they can spike blood sugar levels quickly. Consider substituting mangoes with papayas or melons, which have fewer carbs.
  • Cherries: Despite their small size, cherries are high in natural sugars and carbs. A cup of cherries contains around 22 grams of carbs, making them less than ideal for low-carb diets. Opt for lower-carb alternatives like blueberries or blackberries.
  • Pineapples: Pineapples are known for their juicy sweetness and high vitamin C content. However, a cup of pineapple contains 22 grams of carbs and a high glycemic index, which can quickly elevate blood sugar levels. Substitute pineapple with fruits like strawberries or kiwi, which have a lower carb count.
  • Figs: Figs are nutrient-rich and high in fiber but also high in natural sugars. Fresh figs contain around 9 grams of carbs per fig, and dried figs have even more due to the concentrated sugar content. Instead, consider snacking on lower-carb fruits like raspberries.

Dried Fruits

Dried fruits are highly concentrated sources of natural sugars and carbs due to the removal of water content during the drying process.

  • Raisins, Dates, Apricots: These dried fruits contain significantly higher carb counts than their fresh counterparts. For instance, one small box of raisins (about 1.5 ounces) has 34 grams of carbs. Dates and dried apricots can exceed 60 grams of carbs per serving. These concentrated sources of carbs can easily derail a low-carb diet. Fresh or frozen berries are preferable options for a sweet snack.

Fruit Juices and Smoothies

Fruit juices and smoothies can be deceptively high in carbs due to their high concentration of fruit sugars.

  • Juices: Fruit juices often lack fiber and contain concentrated sugars that cause a rapid increase in blood sugar levels. An 8-ounce serving of orange juice contains about 26 grams of carbs, nearly equivalent to a full orange without the fiber content that moderates sugar absorption. Instead, try drinking water infused with lemon or cucumber slices.
  • Smoothies: Smoothies made primarily from high-carb fruits can quickly exceed carb limits, especially when adding sweetened yogurts or fruit juices. To keep smoothies low-carb, use unsweetened almond milk or water as a base and include low-carb fruits like spinach, cucumber, and berries.

Fruits Lower in Carbs: Safe Alternatives

While some fruits should be avoided on a low-carb diet, there are still options available that can be enjoyed in moderation.

  • Berries: Berries, such as strawberries, raspberries, blackberries, and blueberries, are lower in carbs compared to other fruits and provide high amounts of fiber and antioxidants. A cup of strawberries has about 11 grams of carbs, making them a favorable option for those on a low-carb diet.
  • Avocados: Avocados are low-carb, with only 3 grams of net carbs per half avocado. They are high in healthy fats, which promote satiety and support heart health.
  • Olives: Olives are low-carb fruits rich in healthy fats and antioxidants. They are a good snack choice, with just 2 grams of net carbs per 10 olives.
  • Coconut: Coconut meat and unsweetened coconut flakes have a low carb content and provide healthy fats and fiber, making them a versatile ingredient for low-carb diets.

Tips for Incorporating Fruits on a Low-Carb Diet

  • Portion Control: Even low-carb fruits can add up in carb content if eaten in large amounts. Be mindful of portion sizes to avoid exceeding daily carb limits.
  • Pairing with Protein/Fat: Pairing fruits with protein or fats, like nuts, seeds, or cheese, can help slow down the absorption of sugars, leading to more stable blood sugar levels.
  • Frozen Fruits: Frozen fruits, especially berries, can be enjoyed in small quantities as toppings for yogurt or low-carb desserts.


Selecting the right fruits while following a low-carb diet is crucial for maintaining dietary goals. While high-sugar and high-carb fruits can derail your progress, several low-carb options still allow you to enjoy the natural sweetness and health benefits of fruits. Understanding the carb content and glycemic impact of different fruits helps ensure that your low-carb diet remains effective.
