The keto diet is a low-carb, high-fat eating plan that restricts carbohydrate intake to 20–50 grams per day. This diet is often used for weight loss and diabetes prevention, but it can also be used to treat epilepsy and other seizure disorders. Fruits are usually high in carbs, but some are suitable for a keto diet when eaten in moderation. These include avocados, raspberries, strawberries, lemons, and limes. These fruits are low in net carbs (total carbs minus fibre) and can be added to meals in creative ways, such as in smoothies or salads.

What You'll Learn
Avocados are keto-friendly
The keto diet is a low-carb, high-fat, and moderate-protein diet. It involves limiting carbohydrate intake to less than 20-50 grams per day, which can be challenging for those who enjoy eating fruits, as they tend to be high in carbs.
However, avocados are a keto-friendly option. Although avocados are often used and referred to as a vegetable, they are, in fact, biologically considered a fruit. They are a good source of healthy fats, which makes them a great addition to a ketogenic diet. Avocados are also high in fibre, with 6.7 grams, meaning the net carbs are less than 2 grams for half an avocado.
Avocados are also a good source of essential nutrients, including vitamin C, vitamin K, potassium, calcium, magnesium, B vitamins, and folate. Eating avocados regularly can help reduce levels of "bad" cholesterol and improve heart health. The recommended serving size of avocado is around one-third of a medium-sized fruit.
In addition to avocados, other keto-friendly fruits include berries, lemons, and limes. These fruits can be enjoyed in moderation as part of a ketogenic diet.

Berries are low-carb
The keto diet is a low-carb, high-fat eating plan that limits daily carbohydrate consumption to 20–50 grams. This amounts to just 5–10% of your total daily calories coming from carbohydrates. As a result, many fruits are considered off-limits on the keto diet due to their high carbohydrate content.
However, berries are generally low in carbohydrates and can be enjoyed in moderation on a ketogenic diet. Strawberries, for example, contain just 11.7 grams of carbohydrates per 152-gram serving, as well as 3 grams of fibre, which is indigestible and doesn't count towards your total daily carb count. This means strawberries have a net carb count of only 8.7 grams per cup.
Raspberries are another keto-friendly berry, with a net carb count of around 5 grams per 100 grams. They are also a source of vitamins C and K, which protect immune and bone health. Blackberries are also a good option, offering fibre to support digestion.
In addition to being low in carbs, berries offer a host of other health benefits. They are loaded with antioxidants, such as anthocyanins, ellagic acid, and procyanidins, as well as vitamins and minerals like vitamin C, manganese, and folate.
While berries are a great low-carb option, it's important to remember that you don't need to eat fruit at all on a keto diet. All the nutrients found in fruit can also be obtained from vegetables, without the sugar content. So, if you're unsure about whether a particular berry is keto-friendly, it may be best to opt for low-carb vegetables instead.

Lemons are low-carb
The keto diet is a restrictive eating plan focused on extremely low carbohydrate consumption. People following the keto diet are instructed to limit carbohydrates to less than 50 grams per day. There is some variation in the amount of carbs permitted per day, and some sources say to consume no more than 20 grams daily.
Lemons are low in carbohydrates and sugar, making them suitable for many keto-friendly recipes. One medium-sized lemon contains just 5 grams of net carbs, a relatively small amount compared to other fruits. Lemon juice provides only around 2 grams of carbs per ounce, according to USDA data. This isn't enough to raise your blood sugar and will keep insulin levels low.
Drinking lemon water is a great way to stay hydrated and can help aid in digestion. Lemon water can be consumed during a fast as it is low in calories and carbohydrates and will not impact your blood sugar or insulin levels. However, it is important to remember that lemons do contain some carbs, and excessive intake could raise your blood sugar levels and push you out of ketosis.
Lemons are also a rich source of essential nutrients. They are particularly high in vitamin C, which promotes a strengthened immune system and enhances overall health. They are also a good source of folate, potassium, and vitamin B6. In addition, lemons are high in fibre and contain pectin, a type of fibre associated with several health benefits. Pectin can help stabilize blood sugar levels, fight inflammation, and slow the growth of cancer cells.
Lemons can be used in a variety of ways on the keto diet. Lemon juice can be added to water or used in sauces and dressings. Lemon zest can also be added to recipes, and lemons can be baked into keto-friendly desserts.

Tomatoes are low-carb
The keto diet is a restrictive eating plan focused on extremely low-carbohydrate consumption. People following the keto diet are instructed to limit carbohydrates to less than 50 grams per day, with some sources suggesting no more than 20 grams.
Tomatoes are a fruit with a significantly lower carb count than many other fruits, making them a good choice for those on a low-carb diet. They are also low in calories and rich in beneficial plant compounds, vitamins, minerals, and antioxidants. One cup (180 grams) of raw tomatoes contains about 7 grams of carbs and 2 grams of fibre, resulting in only 5 grams of net carbs.
The number of carbs in tomatoes can vary depending on the variety and size of the tomato, or whether it is a tomato product. For example, a medium-sized tomato has a net carb count of roughly 2.7 grams, while one source states that cherry tomatoes are low in carbs. People following a low-carb diet should check the labels of tomato products for total carbs and any added sugar, and avoid overly processed tomato products or those with added salt.
Tomatoes can be enjoyed in a variety of ways on the keto diet. They can be eaten raw in salads, diced in keto recipes, or cooked in homemade tomato sauce. They can also be paired with other low-carb foods, such as avocado, eggs, and cheese, to create a balanced meal.

Olives are low-carb
The keto diet is a restrictive eating plan focused on extremely low carbohydrate consumption. People following the keto diet are instructed to limit carbohydrates to less than 50 grams per day, with some sources suggesting no more than 20 grams daily. The standard approach to this plan requires about 70 to 80 percent of your calories to come from fat, 10 to 20 percent from protein, and 5 to 10 percent from carbs.
Olives are a keto-approved fruit that can be consumed plentifully. Eighty percent of olives' total calories come from fat, with only 5% of an olive made up of carbs, making them the perfect snack for the everyday keto dieter. They are also extremely nutrient-dense and have profound anti-inflammatory properties. Olives are also a great source of healthy fats, with the fat content being approximately 75% oleic acid, a monounsaturated fatty acid. These types of fats have several health benefits, including a decreased risk of heart disease.
Olives are also a convenient snack option when hunger strikes, as they are much easier to grab than, say, an avocado. They are also a great source of healthy fats, which can be extracted to produce extra virgin olive oil, a staple in the ketogenic diet.
Olives come in several types, both green and black, and can be cured in different solutions to give them different tastes. However, not all olives have the same nutrient value, and many are soaked in a solution that contains lye and water to soften them.
Other keto-friendly fruits include avocados, raspberries, strawberries, lemons, tomatoes, and watermelon.
