The keto diet is a low-carb, high-fat eating plan that was originally developed to reduce epileptic seizures in children. It is also used for weight loss, diabetes prevention, and management. Fruits contain natural sugars that contribute to a person's daily carbohydrate intake, so some fruits are restricted on the keto diet. However, some fruits are suitable as part of a keto meal plan, including avocados, lemons, tomatoes, berries, and kiwis. Citrus fruits like lemons are commonly used in ketogenic menus, especially in desserts, due to their low glycemic index and high vitamin content.
| Characteristics | Values |
|---|---|
| Carbohydrates | Less than 15 grams per serving |
| Sugars | Natural sugars are allowed |
| Glycemic Index | Low GI fruits are allowed |
| Fiber | High-fiber fruits are suitable |
| Net Carb Count | The only thing that matters is the net carb count |
| Examples | Lemons, limes, avocados, strawberries, olives, raspberries, blackberries, blueberries, tomatoes, coconuts, watermelon |

What You'll Learn
Lemons are a keto-friendly fruit
Lemons are keto-friendly fruits that can be incorporated into various keto-friendly recipes. They are low in carbohydrates and sugar, with an average-sized lemon containing about 6 grams of carbohydrates, 1.8 grams of fibre, and 4.2 grams of net carbs. Lemons have a high vitamin C content, which promotes a strengthened immune system and enhances overall health. The acid in lemon juice can also aid digestion and may even help with weight loss.
Lemons are versatile and can be used in drinks, desserts, and savoury dishes. Lemon water, for example, is a great way to stay hydrated and aid digestion. Lemon juice should not break a keto fast, as it is low in calories and carbohydrates. However, it is important to watch your intake of added sugars or artificial sweeteners, as they can quickly increase your carbohydrate intake.
Lemons are the most commonly used fruits in ketogenic menus, especially desserts. Their low glycemic index and high vitamin content make them essential for keto menus. They can be used in sweet or savoury salads, dishes, or desserts, and their antioxidant and astringent properties help cleanse and renew the body.
Overall, lemons are a great addition to a keto diet, providing flavour and health benefits without compromising ketosis.

Avocados are low-carb and keto-friendly
The keto diet is a low-carb, high-fat diet that aims to put the body into a state of ketosis, where it burns fat instead of sugar. Fruits contain natural sugars, so they can be difficult to fit into a keto meal plan. However, some fruits are lower in carbohydrates and can be enjoyed in moderation as part of a keto diet.
Avocados are one such fruit that is low in carbs and keto-friendly. Avocados are classified as fruits, although they are often used like vegetables in savoury dishes. They are a good source of healthy fats, vitamins, minerals, and fibre. The predominant fat in avocados is unsaturated, making them a great substitute for foods high in saturated fat. They also have a low carbohydrate content and a high lipid content. This makes them a perfect fit for the keto diet, which is based on eating low-carb, high-fat foods.
The recommended serving size of avocado for someone on the keto diet is around one-third of a medium-sized fruit. This provides 8 grams of total fat, 6 grams of healthy fats, and only 4 grams of carbohydrates. Avocados also contain fibre, which reduces the net carbs (the total carbs minus grams of fibre). For example, half an avocado (100 grams) contains 8.5 grams of carbs and 6.7 grams of fibre, resulting in less than 2 grams of net carbs.
In addition to their nutritional benefits, avocados are a convenient choice for the keto diet because they are available all year round. They can be easily incorporated into a variety of dishes, such as smoothies, toast, or eggs, to meet your nutrient needs throughout the day.
Other keto-friendly fruits include strawberries, olives, lemons, raspberries, and citrus fruits. It is important to note that while these fruits are generally considered low-carb, portion control is still necessary to stay within the carb limits of the keto diet.

Olives are high in fat and antioxidants
The keto diet is a low-carb, high-fat eating plan designed to put a person into a state of ketosis, where the body burns fat instead of sugar. While the keto diet limits the consumption of fruits due to their carb count, some fruits fit the keto dietary plan in moderation. These include avocados, lemons, tomatoes, berries, and kiwis.
Olives, which are technically categorized as a fruit, are high in fat and antioxidants. They are a good source of vitamin E and other powerful antioxidants. Studies show that they are good for the heart and may protect against osteoporosis and cancer. The healthy fats in olives are extracted to produce olive oil, a key component of the Mediterranean diet. Olives are also enjoyed in salads, sandwiches, and spreads.
Olives contain 11–15% fat, 74% of which is oleic acid, a type of monounsaturated fatty acid that is the main component of olive oil. Oleic acid is linked to several health benefits, including decreased inflammation and a reduced risk of heart disease. It may also regulate cholesterol levels and protect LDL (bad) cholesterol from oxidation.
Olives are also a good source of iron, which is important for red blood cells to transport oxygen. They contain copper, an essential mineral often lacking in the typical Western diet, and calcium, which is essential for bone, muscle, and nerve function. Some methods of olive processing add calcium to the fruit. However, olives may contain high amounts of sodium if packaged in saltwater.
The vitamins and antioxidants found in olives offer important health benefits. Olives are rich in vitamin E, which can improve skin health and boost the immune system. They also contain phytonutrients, including antioxidants that reduce inflammation, which can damage healthy cells and lead to cancer. People who eat diets high in monounsaturated fat, like that found in olives, tend to have better blood sugar control.

Kiwis are high in net carbs
The keto diet is a low-carb, high-fat diet that aims to put the body into a state of ketosis, where it burns fat for energy instead of carbohydrates. This diet typically involves strict regulation of calorie intake for each of the three macronutrients: fats, protein, and carbohydrates. While fruits are often removed from the diet due to their natural sugar content, some fruits can be included in moderation.
Kiwis, or kiwifruits, are high in net carbs. A 100-gram serving of kiwi contains 14 grams of total carbohydrates. After accounting for the 3 grams of dietary fibre, it still contains 11 grams of net carbs. This constitutes a significant proportion of the daily carb limit on a strict ketogenic diet, which is typically between 20 and 50 grams per day. Therefore, including kiwi in a ketogenic diet can be challenging and may even jeopardise the state of ketosis.
However, it is important to note that kiwi is a rich source of essential vitamins and minerals. It is particularly high in vitamin C, with 74.7 mg per 100-gram serving, outranking other vitamin C-rich fruits like oranges. Kiwi also provides dietary fibre and is a source of vitamin K, potassium, and various other nutrients.
Despite the challenges posed by its higher net carb content, some individuals who have followed a strict keto diet for several years may choose to reintroduce kiwi to their diet. This decision may be influenced by the nutritional benefits of kiwi and a shift in priorities towards longevity and quality of life rather than maintaining full-time ketosis.
In conclusion, while kiwi is a nutrient-rich fruit, its high net carb content makes it less compatible with a strict ketogenic diet. Those adhering to a ketogenic diet may need to monitor their carb intake throughout the day if they choose to consume kiwi.

Blackberries are high in fibre
The keto diet is a low-carb, high-fat diet that promotes weight loss and can be challenging to incorporate fruit into. However, some fruits are suitable for a keto meal plan, including avocados, lemons, tomatoes, berries, and kiwis. Fruits that are lower in sugars and higher in fibre are more suitable for the keto diet, as fibre is indigestible and lowers the net carb count of the fruit.
Blackberries are a type of berry that is high in fibre. A cup of raw blackberries contains almost 8 grams of fibre, which is 14% of the recommended daily fibre allowance. They contain both soluble and insoluble fibre, which have different health benefits. Insoluble fibre does not dissolve in water but aids healthy digestion by increasing the bulk of stools, making them easier to pass. Soluble fibre, on the other hand, dissolves in water and can help to lower blood sugar levels and maintain healthy cholesterol levels.
Blackberries are also a good source of vitamins and minerals, including vitamins C, K, and A, and manganese. They are low in calories, carbs, and fat, and have a low glycemic index (GI) of 25, meaning they are unlikely to spike blood sugar levels. Blackberries also contain antioxidants, which help to fight against the adverse effects of free radicals in the body, such as cell damage, ageing, cancer, and heart disease.
Blackberries can be easily incorporated into a healthy diet, such as in fruit salads with yogurt, added to cereals, or in fruit smoothies. They are a great option for satisfying a sweet tooth while maintaining a low-carb eating plan.
