The keto diet is a low-carb, high-fat diet that limits the number of carbohydrates consumed, putting the body into a state of ketosis where it burns fat for fuel instead of carbohydrates. While fruit is normally considered healthy, it tends to be high in carbohydrates and natural sugars, which can make it difficult to keep within the strict carbohydrate limits of the keto diet. Apples, in particular, are considered too high in sugar and carbohydrates to be included in a keto diet, with a single medium-sized apple containing more than 22 grams of net carbs, which is enough to exceed the entire recommended daily carb intake for someone on the keto diet.

What You'll Learn

Apples are high in sugar and carbohydrates
The keto diet is a low-carb, high-fat diet that limits many fruits. The diet aims to induce ketosis, a metabolic state where the body burns fat instead of sugar. To stay in ketosis, it is recommended to limit carbohydrate intake to 25-50 grams per day on a 2,000-calorie diet, which is typically 5-10% of total calories.
Apples are generally considered too high in sugar and carbohydrates for the keto diet. A single medium-sized apple contains roughly 22-25 grams of net carbs, mostly from natural sugars. This amount alone can exceed the recommended daily carb limit for keto dieters. Even Granny Smith apples, the variety with the least sugar, contain around 11 grams of net carbs per 100-gram serving (about 3/5 of an apple).
While apples provide essential nutrients, their high carb content can quickly add up and impede ketosis. Therefore, it is best to limit apple consumption on a keto diet or use them sparingly in small portions, such as in recipes where a small amount of apple is spread over several servings.
Instead of apples, keto dieters can opt for low-carb fruits like avocados, berries, olives, lemons, and tomatoes, which can be consumed in moderation while still maintaining ketosis. These fruits offer nutritional benefits without the high sugar and carb content of apples.

Keto diet is an extremely low-carb diet
The keto diet is a very low-carbohydrate diet. It involves limiting your carbohydrate intake so that your body enters a state of ketosis, where it burns fat instead of carbohydrates for fuel. Typically, on a keto diet, you aim to get 80% of your calories from fat and only 5–10% from carbohydrates. This means that many foods that are conventionally considered healthy, such as fruits, legumes, dairy, starchy vegetables, and whole grains, are not suitable for a keto diet.
Fruits tend to be high in carbohydrates and natural sugars, which can quickly add up and exceed the recommended daily carb intake for keto. For this reason, it is generally recommended to avoid fruits or choose low-carb fruits such as berries, avocados, olives, lemons, and tomatoes. These fruits can be consumed in moderation while still maintaining ketosis.
Some examples of fruits to avoid on a keto diet include apples, bananas, grapes, pineapple, mangoes, and oranges. These fruits have a high sugar and carbohydrate content, which can impede progress on a keto diet. For instance, a medium-sized apple contains more than 22 grams of net carbs, which is enough to exceed the daily carb limit for keto.
It is important to note that the keto diet can be restrictive and may lead to deficiencies in essential nutrients. It is always recommended to consult with a healthcare professional or registered dietitian to determine if the keto diet is suitable for you and to ensure you are getting all the necessary nutrients while maintaining a healthy and balanced diet.
While it may be challenging, it is possible to incorporate some fruits into a keto diet by being mindful of portion sizes and choosing low-carb options. This can help ensure you are getting the nutritional benefits of fruits while still maintaining ketosis.

Apples can be eaten in small portions
The keto diet is a low-carb, high-fat diet that limits the consumption of many fruits due to their high natural sugar content. While apples are considered too high in sugar and carbohydrates for the keto diet, with a medium-sized apple containing more than 22 grams of net carbs, they can be consumed in small portions.
A ketogenic diet typically restricts carbohydrates to 25-50 grams per day on a 2,000-calorie diet, which is a significant reduction from the recommended daily intake of 225-325 grams. As a result, fruits like apples, which are high in natural sugars (fructose and glucose), can quickly add up in carb counts and impede ketosis.
However, small portions of apples, such as in the Apple and Ham Flatbread recipe, can be incorporated sparingly without disrupting ketosis. Granny Smith apples, for example, have the lowest sugar content among apple varieties, containing around 11 grams of net carbs per 100 grams serving.
It is important to note that the keto diet can be restrictive and challenging to follow, and it is always recommended to consult a healthcare provider or registered dietitian to ensure it is right for your health and to help you follow it in a nutritious way.

Other fruits to eat on keto include avocado, berries, and olives
Apples are not keto-friendly due to their high carbohydrate content. However, there are some fruits that are suitable for a keto diet, including avocado, berries, and olives.
Avocados are a popular choice for those following a keto diet because they are high in healthy monounsaturated fats, which can help lower the risk of heart disease and stroke by reducing bad cholesterol levels. They are also a good source of potassium and B vitamins, and a whole avocado contains only 17 grams of carbs, 14 grams of which are fibre, and 30 grams of fat.
Berries are another keto-friendly option, as they are relatively low in carbs and contain healthy antioxidants. Strawberries, raspberries, blackberries, and blueberries are all good choices, but remember to consume them in moderation as they do contain some sugar.
Olives are also a keto-friendly snack, as they are rich in healthy monounsaturated fats and antioxidants from vitamin E. They are low in calories and almost devoid of carbs, but it is important to note that they can contain high levels of sodium.
In addition to these fruits, other keto-friendly foods include non-starchy vegetables like broccoli, cauliflower, zucchini, and bell peppers, as well as nuts, seeds, and high-fat dairy products.

Consult a healthcare provider for a personalised keto diet plan
The keto diet is a low-carb, high-fat diet that aims to put your body into ketosis, burning fat instead of sugar. While it can be a healthful diet, it is not fully balanced due to its restrictive nature. As a result, people on the keto diet are often at risk of deficiencies in essential nutrients such as vitamins B, C, and D, calcium, selenium, and magnesium.
Before starting any new diet, it is important to consult a healthcare provider or registered dietitian to decide whether the diet is right for you and to ensure you are getting all the nutrients your body needs. They can help you create a personalised keto diet plan that takes into account your unique health profile, including your health goals, past weight loss experiences, dietary preferences, and any medical conditions you may be managing.
For example, a keto diet plan can be tailored to fit your food preferences, budget, and how often you like to eat. It can also be combined with high protein for a winning weight loss and body composition improvement strategy. Additionally, a healthcare provider can help you maximise the carbs you do eat and ensure you are focusing on quality foods, such as wild seafood, organic eggs, and grass-fed butter and steak.
By answering a series of questions about your lifestyle and preferences, a healthcare provider can recommend a program that best meets your needs and helps you set yourself up for success. This can include providing recipes and shopping lists to simplify your keto journey.
