Can You Eat Fruit On Keto?

The main job on keto is cutting your carb intake, so it’s easy to see why fruit gets a bad reputation. But here’s the thing, completely avoiding this colourful food group means you miss out on vital vitamins and minerals that support your health. You just need to know which low-carb fruits to choose!


While keeping your daily carb limit low is the key to staying in ketosis, you don’t want to miss out on the health benefits that fruits offer. Many options are also a good source of antioxidants.


Sure, many tropical fruit options are off the table. But choices like berries and avocados are great keto fruits that can make a great addition to your diet. When you eat some fruits, you get fibre, which is brilliant for your health. To work out the net grams of carbohydrates, you just subtract the fibre from the total.


But a word of warning: All fruit juice is bad news. It’s pure sugar without the fibre. Just stay away!


The key is choosing wisely. When planned right, fruit can provide balanced nutrition to complement your keto meal plan and even help you lose weight.

Benefits of Eating Fruit on Keto

While keeping your carb intake low is super vital to staying in the blissful state of ketosis, it's also important not to miss out on all fruits out there (And their health benefits!). 

 

Though tropical fruit options, bananas and grapes are often off the table in anything more than micro servings at the start of a strict keto diet, fruits like berries and avocados are great keto fruits, and offer an array of benefits:

 

  • Disease-fighting antioxidants and phytochemicals like lycopene, anthocyanins, quercetin, and lutein. These help reduce inflammation and protect cells.
     
  • Essential vitamins and minerals like Vitamin C for immunity and skin health, potassium for heart function, folate for cell growth, and magnesium for bone strength.
     
  • Fibre to support satiety, healthy gut bacteria, digestion, and regularity. This promotes weight management.
     
  • Flavour and sweetness to prevent burnout from overly restrictive dieting. The natural sugars add palatability.
     
  • Versatility as ingredients in keto recipes like smoothies, chia puddings, muffins, savoury salads and more. They liven up meal prep.
     
  • Low glycemic impact compared to processed sweets. Berries, for example, have a minimal effect on blood sugar.
     
  • Hydration from the high water content in many fruits. This aids metabolic and brain health.

 

When appropriately planned, fruits can provide balanced nutrition to complement your keto diet and promote sustainable, long-term success.

The Best Fruits You Can Eat on a Keto Diet

Honestly, when you're figuring out what to eat on the keto diet, the following fruits are the main ones you should really be consuming. Otherwise, you might find it a real struggle to keep your carb intake low enough.

List of Keto-Friendly Fruits

Here are the only fruits you need to think about on keto. Let's go through each of these 'Keto allies'…

1. AVOCADOS

The Ultimate Keto Fruit! 


This is the undisputed king of keto fruit! An avocado is a high-fat superstar, very low in net carbs. It's perfect when you eat on a keto diet.


Nutrition per 1/2 Avocado Nutrition per 100g
Calories: 161 Calories: 167
Fat: 15g Fat: 15g
Carbs: 9g Carbs: 9g
Fiber: 7g Fiber: 7g
Net carbs: 2g Net carbs: 2g
Protein: 2g Protein: 2g

Avocados are full of healthy fats and are a fantastic good source of potassium. Being so rich in fat and fibre, they really help you feel full and keep your blood sugar steady. They contain far fewer carbs than other fruits, making them a top choice.

Research shows that consuming more lutein and zeaxanthin may prevent age-related macular degeneration and cataracts.

Overall, avocado is one of the healthiest keto fruit options with plenty of fiber, vitamins, minerals, and beneficial plant compounds.

2. STRAWBERRIES

Strawberries are relatively low in carbs and can fit into your lifestyle in moderation. A surprise entry on the list of fruits to eat!


Nutrition per 1/4 Cup Strawberries Nutrition per 100g
Calories: 13 Calories: 32
Fat: 0g Fat: 0.3g
Carbs: 4g Carbs: 8g
Fiber: 1g Fiber: 2g
Net carbs: 3g Net carbs: 6g
Protein: 0g Protein: 0.7g

They won't send your blood sugar on a rollercoaster. You might be surprised that one cup of strawberry halves contains just about 8.5 grams of carbs, not bad at all! They're also rich in vitamin c and a good source of manganese.

Strawberries provide a range of disease-fighting antioxidants and polyphenols, including anthocyanins, which give strawberries their red colour. Research shows these antioxidants reduce inflammation, protect the heart, and may lower the risk of type 2 diabetes.

3. RASPBERRIES

Like strawberries, raspberries are fantastic low-carb fruits to eat. Their high fibre content is a huge plus, as it helps to slow down sugar absorption.


Nutrition per 1/4 Cup Raspberries Nutrition per 100g
Calories: 15 Calories: 52
Fat: 0g Fat: 0.7g
Carbs: 4g Carbs: 12g
Fiber: 2g Fiber: 7g
Net carbs: 2g Net carbs: 5g
Protein: 0g Protein: 1.2g

With only 5 g of net carbs per 100g, these are an easy choice. They are packed with antioxidants and other nutrients like potassium and vitamin c while being naturally low in calories. A handful is a perfect way to keep that carb count low.

Along with strawberries, raspberries have a low glycemic index (GI), meaning their sugar is absorbed more slowly and they do not cause major blood sugar spikes.


Incorporating raspberries into a keto eating pattern can provide critical nutrients and plant compounds that fight disease, enhance weight loss results, and satisfy sweet cravings - an all-around win.

4. BLACKBERRIES

Blackberries are incredibly high in fibre and are another one of the best fruits you can eat on keto.


Nutrition per 1/4 Cup Blackberries Nutrition per 100g
Calories: 15 Calories: 43
Fat: 0g Fat: 0.5g
Carbs: 4g Carbs: 10g
Fiber: 2g Fiber: 5g
Net carbs: 2g Net carbs: 5g
Protein: 1g Protein: 1.4g

The fibre helps keep you regular and feeling full. A small serving offers a huge punch of vitamin C. Because they are also low in net carbs, they can easily fit into your diet.

Some early research indicates blackberries could help prevent and manage metabolic syndrome, which raises your risk for stroke, heart disease, and diabetes. Animal studies also show potential anti-cancer effects.

With only 5g of net carbs per 100g, blackberries can easily fit into a keto diet, especially considering the immense amount of nutrition and fibre they provide.

5. LEMONS

Don’t forget these citrus heroes! They fit perfectly into a keto diet. A squeeze in your water gives you a boost of vitamin C, and the amount of carbs is tiny.


Nutrition per 1/2 Lemon Nutrition per 100g
Calories: 7 Calories: 29
Fat: 0g Fat: 0.3g
Carbs: 3g Carbs: 9.3g
Fiber: 0.5g Fiber: 2.8g
Net carbs: 2.5g Net carbs: 6.5g
Protein: 0.3g Protein: 1.1g

Lemons shine on a ketogenic diet thanks to their low net carb count and high vitamin C content. One 100g serving provides over 50% of the RDI for vitamin C. This vitamin acts as an antioxidant and is essential for immune function and collagen production.

Research indicates that the vitamin C in lemons lowers blood pressure and cholesterol levels, reducing risk factors for heart disease. The combination of plant compounds and vitamin C may also prevent free radical damage by acting as antioxidants.

6. LIMES

Like lemons, limes provide a nutritious, low-calorie, low-carb fruit option. They have antioxidant and anti-inflammatory benefits.

 

Nutrition per 1 Lime Nutrition per 100g
Calories: 6 Calories: 30
Fat: 0g Fat: 0.2g
Carbs: 3g Carbs: 7.7g
Fiber: 0.4g Fiber: 2.8g
Net carbs: 2.6g Net carbs: 4.9g
Protein: 0.1g Protein: 0.7g

 

Limes are low in net carbs while providing good amounts of vitamin C - over 30% of the Daily Value in 100g. Lime juice contains potent antioxidants like hesperidin, quercetin, kaempferol, and limonene.

 Drinking lime juice diluted in water creates an excellent hydrating beverage that is perfect for a post-workout refreshment while on keto.

 

Limes also have antimicrobial properties, likely due to compounds like limonene in their peels. Early research shows essential oils from lime peels can suppress bacterial growth that causes foodborne illnesses.

7. COCONUT

Coconut is loaded with fibre and a great source of the keto ‘wonder fats’, MCTs. For that reason alone, it can be a great addition to your keto meal plan.


Nutrition per 1/4 Cup Unsweetened Shredded Coconut Nutrition per 100g (Unsweetened, Shredded)
Calories: 187 Calories: 354
Fat: 18g Fat: 33g
Carbs: 4g Carbs: 15g
Fiber: 2.5g Fiber: 9g
Net carbs: 1.5g Net carbs: 6g
Protein: 1.5g Protein: 3g

Unlike other fats, MCTs are metabolized differently and are linked to health benefits related to energy, weight management, and cognition.

Consuming coconut oil or coconut butter makes adding MCTs to meals and beverages easy. Just stick to unsweetened varieties and account for net carbs.

8. STAR FRUIT

Although hard to find, star fruit (or carambola) is a tropical fruit that is an excellent low-carb choice for keto diets.

 

Nutrition per 1/4 Starfruit Nutrition per 100g
Calories: 6 Calories: 31
Fat: 0g Fat: 0.3g
Carbs: 2g Carbs: 7.7g
Fiber: 1g Fiber: 2.8g
Net carbs: 1g Net carbs: 4.9g
Protein: 0g Protein: 0.6g

 

Although uncommon, star fruit (or carambola) is worth including in a ketogenic diet because it's low in net carbs while providing antioxidants and fibre.

With only 5g of net carbs per 100g serving, star fruit earns its place among low-carb fruits. Its unique tropical flavour and antioxidants make it a tasty choice for keto dieters.

When choosing fruit on keto, choose lower sugar, higher fiber options. Prioritize nutrition and enjoy fruits in moderation as part of a well-formulated ketogenic diet.

One Fruit to Consider In Small Amounts... Blueberries

Blueberries don't quite qualify as a low-carb fruit at about 12 grams of net carbs per 100 grams. However, they still deserve consideration for inclusion in a well-formulated ketogenic diet due to their incredibly high antioxidant content.
 

Nutrient (per 100g) Amount
Calories 57
Fat 0.3g
Carbs 14g
Fiber 2.4g
Net Carbs 11.6g
Protein 0.7g

Blueberries are a nutritional powerhouse, but they do have more carbs. While not one of the best for strict keto, their antioxidant level is so high they are worth considering in small amounts.


Fresh blueberries can be pricey, but frozen wild blueberries are more affordable while still retaining great flavour and nutritional value.

Fruits to Avoid on Keto

Okay, I haven't included tomatoes on the list above, as most people see them as low-carb vegetables, not fruit! The same goes for olives. Both are fine in moderation.


This table shows why we are so specific about the fruits to eat on keto. You can see how the total carbs stack up:


Fruit Total Carbs Fiber Net Carbs
Raspberries 12g 6g 6g
Blackberries 10g 5g 5g
Strawberries 8g 2g 6g
Blueberries 14g 2g 12g
Lemon 3g 1g 2g
Lime 11g 2g 9g
Avocado 9g 7g 2g
Tomato 4g 1g 3g
Watermelon 8g 1g 7g
Cantaloupe 8g 1g 7g
Peach 10g 2g 8g
Plum 11g 1g 10g
Clementine 12g 2g 10g
Kiwi 15g 3g 12g
Grapes 18g 1g 17g
Mango 15g 2g 13g
Apple 14g 2g 12g
Banana 23g 3g 20g
Orange 12g 2g 10g

Berries are clear winners, with raspberries at their lowest at just 3g net carbs per serving size.


Higher sugar options like bananas and grapes should be avoided. They can have over 15 grams of carbs per serving and will knock you out of ketosis. Your diet should focus on the 8 keto-friendly foods we talk about, not high-sugar fruits or starchy vegetables.

Keeping Fruit Portions in Check on Keto

While some low-carb fruits can fit into a keto diet, portions must be controlled to avoid disrupting ketosis. With daily carbs ranging from 20-50g on keto, fruits can account for a significant percentage if you overindulge.

 

Remember to subtract the grams of fibre from the grams of carbs to get your net carbs!

 

Berries are great but stick to 1/2 cup or less daily. Spread intake throughout meals and snacks rather than consuming in one sitting. 

 

A 1/4 cup or less is a good guideline for moderate-sugar fruits like blueberries and starfruit. High-carb bananas and mangos should be avoided or limited to a few small bites.

 

That being said, with mindful portions and smart substitutions, even fruits with more natural sugars can be enjoyed occasionally on keto. The key is being diligent about carb counts so fruit can stay within your goals.

 

After you have been in Ketosis for some time, you become able to handle a few more carbs than when starting out. Use Ketone Strips or an Electronic Ketone Monitor to monitor your levels while testing your resilience to higher-carb foods. 

 

You may find that you can handle more carbs than someone else on the keto diet.

Everyone is different!
