The keto diet is a low-carb, high-fat diet that involves reducing carbohydrate intake and replacing it with fat. This diet is designed to induce ketosis, a natural metabolic state where the body burns fat for energy instead of carbohydrates. While the keto diet has become increasingly popular, it can be challenging to determine which foods are keto-friendly, especially when it comes to fruits like apples.
Apples are a type of fruit that is generally considered to be high in carbohydrates. On a keto diet, it is recommended to limit carbohydrate intake to around 20-50 grams per day. A medium-sized apple typically contains about 21 grams of carbohydrates. Therefore, consuming an apple can quickly add up to a significant portion of the daily carbohydrate limit.
However, it is important to note that not all apples are created equal when it comes to their carbohydrate content. For example, Granny Smith apples, which are known for their tart flavour, have the lowest sugar content among apple varieties. A 100-gram serving of a Granny Smith apple with the skin contains around 11 grams of net carbs. In comparison, other popular apple varieties like Gala, Golden Delicious, Liberty, and Fuji apples contain about 11.5 grams of net carbs per 100-gram serving.
While apples may not be the first choice for those on a keto diet due to their relatively high carbohydrate content, they can still be enjoyed in moderation or as part of a larger meal. Additionally, apples provide various nutrients, including vitamins and fibre, which can contribute to a healthy and well-rounded diet.

What You'll Learn
Granny Smith apples are the least sugary variety
Granny Smith apples are indeed the least sugary variety of apple. They contain 12 grams of net carbs, 2.5 grams of fibre, and 14.5 grams of total carbs per 100 grams (3.5 ounces). This is compared to other varieties, such as Gala and Golden/Red Delicious, which contain about 11.5 grams per 100 grams.
Apples, in general, are considered to be a major source of antioxidants in the United States and worldwide. They are rich in fibre, vitamins, minerals, and polyphenols. Polyphenols are a group of antioxidants that fight free radicals in the body and may help prevent cancer, inflammation, heart disease, and weight gain.
However, apples are fairly high in sugar and, therefore, are not considered suitable for a keto diet. On a keto diet, it is recommended to keep total carb intake below 30 grams per day to enter ketosis. Just one apple can make up the majority of the recommended daily carb intake.
If you are on a keto diet and want to include fruit in your meals, it is best to stick to berries (raspberries, blackberries, and strawberries) and lower-carb fruits such as avocados, olives, and tomatoes.

Apples are generally too high in sugar for keto
Apples, in particular, contain around 12g of net carbs per 100g of fruit. This means that a medium-sized apple (180g) may contain about 21g of carbs. This is a significant amount, considering that a keto diet aims for fewer than 20g of net carbs per day.
Even Granny Smith apples, which have the lowest sugar content of any apple variety, still contain around 11g of net carbs per 100g serving (about 3/5 of an apple). This makes them a difficult fruit to fit into a keto diet. Other varieties, such as Gala, Golden/Red Delicious, Liberty, and Fuji, contain about 11.5g per 100g serving.
Therefore, apples are generally too high in sugar to be considered for consumption on a ketogenic diet. If you really can't live without apples, it is best to use them sparingly and in small portions.

Avocados and tomatoes are fruits, not veggies
Avocados and tomatoes are fruits, not vegetables. While they are often used like vegetables and eaten in salads, they are fruits from a botanical perspective.
The main botanical difference between fruits and vegetables is which part of the plant they originate from. Fruits develop from a plant's flower and often contain seeds, whereas vegetables usually consist of stalks, flower buds, roots, or leaves.
Avocados are native to Mexico and grow on trees in warmer climates. They are defined as large berries with a single seed. They have a creamy, smooth texture and are covered by a bumpy, thick, dark-green or blackish skin.
Tomatoes are the second lowest carb fruit and are a keto staple for many savory recipes. They are a great source of vitamin C, potassium, folate, vitamin K, and the antioxidant lycopene, which has been linked to a reduced risk of heart disease and cancer.
While on a keto diet, it is best to avoid most fruits except for berries, avocados, olives, and tomatoes, which can be eaten in moderation.

Apples are nature's candy
Fruit is filled with glucose and fructose, which can decrease ketone production and make it difficult to enter ketosis. That's why it's generally recommended to avoid most fruits on a keto diet, except for a few that are lower in carbs.
Apples are relatively high in carbohydrates, with around 12 grams of net carbs per 100 grams of fruit. That's about 3/5 of the daily carb intake recommended for keto diets. So, if you're following a ketogenic diet, apples are just too high in sugar content to be considered for consumption in most cases.
However, if you can't live without apples, you can try using them sparingly in small portions. For example, you can spread a small amount of apple over several servings of another dish to satisfy your sweet tooth. Granny Smith apples are the least sugary variety, so opt for those if you can.
Remember, there are plenty of other low-carb fruits that you can enjoy on a keto diet, such as berries, avocados, olives, and tomatoes. These fruits can be eaten in moderation and won't kick you out of ketosis.

Fruit juice is best avoided
For example, an 8 oz bottle of apple juice has 28 grams of net carbs, which is already more than the daily carb allowance for most keto dieters. Cranberry juice has a similar amount of net carbs, and store-bought fruit juices typically have well over 10 grams of net carbs per serving. This is too high for most keto diets, and too much sugar can quickly bump you out of ketosis.
In addition to being high in carbs, fruit juices also tend to be low in fiber, as the juicing process removes a large portion of it. Fiber helps slow down any rise in blood sugar, so by removing it, juice becomes even more detrimental to a keto diet.
While there are some keto-friendly fruits like avocados, tomatoes, and berries, it is best to consume them in their whole form or as part of a smoothie to get the full benefit of their fiber content.
If you are craving something fruity, there are some alternatives that are better options than fruit juice. Lemon and lime juices, for instance, are keto-friendly and can be added to water or tea for some extra flavour. You can also try keto-friendly beverages like tea, coffee, or sparkling water.
