How many net carbs are in half an apple?

Knowing how many net carbs are in the foods you eat is important when following a low-carb or keto diet. Net carbs refer to the total carbohydrates in a food minus the fiber and sugar alcohols. Fiber and sugar alcohols are indigestible, so they don’t raise blood sugar like other carbs. When counting net carbs, you only count the carbs that impact blood sugar. This gives you a more accurate assessment of a food’s true carbohydrate content.

One common food that people want to know the net carb count for is apples. Apples are a healthy fruit packed with vitamin C, antioxidants, and fiber. But are they low-carb friendly? Let’s find out how many net carbs are in half an apple.

What Are The Macronutrients In Apples?

Before determining the net carbs in half an apple, let’s look at the full nutritional profile of apples per 100 grams:1

Nutrient Amount
Calories 52
Total Fat 0.2 g
Saturated Fat 0.0 g
Total Carbohydrate 13.8 g
Fiber 2.4 g
Sugars 10.4 g
Protein 0.3 g

As you can see, apples are made up of mostly carbs and fiber, with minimal fat and protein. Now let’s focus specifically on the carb content.

Calculating Net Carbs In Apples

According to the USDA, one small apple (approx. 100 grams) contains:2

– Total carbohydrates: 13.8 grams
– Dietary fiber: 2.4 grams
– Sugars: 10.4 grams

To find the net carbs, we take the total carbs and subtract the fiber:

– Total carbs: 13.8 g
– Fiber: 2.4 g
– Net carbs: 13.8 g – 2.4 g = 11.4 g

So there are approximately 11.4 net carbs in a whole small apple.

Net Carbs In Half An Apple

Now that we know there are 11.4 net carbs in a whole apple, we can divide that in half to determine the net carbs in half an apple:

– Net carbs in 1 small apple: 11.4 g
– Net carbs in 1/2 apple: 11.4 ÷ 2 = 5.7 g

Therefore, half of a small apple contains approximately 5.7 grams of net carbs. This is a reasonable amount of net carbs for a low-carb diet. Some people even fit small apples into a keto diet which aims for under 50 g daily net carbs.

Let’s compare to look at the math another way:

Nutrient In 1 Small Apple In 1/2 Small Apple
Total carbs 13.8 g 6.9 g
Fiber 2.4 g 1.2 g
Net carbs 11.4 g 6.9 g – 1.2 g = 5.7 g

As shown, half of a small apple weighing approx. 100 grams contains 6.9 grams total carbs and 1.2 grams fiber. Subtracting the fiber gives us 5.7 grams net carbs, the same amount as our previous calculation.

Net Carb Counts For Different Apple Sizes

The net carb count will vary slightly depending on the exact size of apple. Here are the approximate net carbs in different apple sizes:2

Apple Size Net Carbs (Whole Apple) Net Carbs (Half Apple)
Small (100g) 11.4g 5.7g
Medium (150g) 17g 8.5g
Large (200g) 23g 11.5g

As you go up in apple size, the net carb count increases since you are consuming more total fruit and carbs. However, on a half apple basis, even large apples contain a moderate amount of net carbs.

Tips For Fitting Apples Into A Low-Carb Diet

Here are some tips for enjoying apples on a low-carb or keto diet:

Stick To Smaller Portions

Aim to keep your portion to half a small or medium apple. This will provide around 5-9 grams net carbs, which can likely be accommodated in a low-carb meal plan.

Pair With Protein and Fat

Eat apples as part of a balanced meal or snack that also contains protein and fat. This helps slow digestion and prevents blood sugar spikes. For instance, enjoy half an apple with natural peanut butter.

Select Low-Carb Accompaniments

Top apples with low-carb mix-ins like cinnamon, unsweetened shredded coconut, lemon juice, sugar-free caramel dip, or chopped walnuts. Avoid high-carb toppings like granola.

Count Towards Your Daily Carb Limit

Double check that half an apple fits within your net carb limit for the day. You may need to balance it out by choosing lower carb foods for other meals and snacks to stay on track.

Increase Fiber Intake

Make sure to get enough fiber from low-carb vegetables, nuts, seeds and even supplements if needed. Fiber helps reduce blood sugar impact and keep you feeling full.

The Blood Sugar Impact Of Apples

In addition to net carbs, it’s useful to understand the glycemic index (GI) of apples to know the impact on blood sugar levels:

– The GI of apples ranges from 29-44, which is low to moderate.3

Foods with a GI below 55 are considered low glycemic and less likely to cause unhealthy blood sugar spikes.4

Apples have a low GI thanks to their fiber content. Fiber helps slow the digestion and absorption of carbs, resulting in a more gradual rise in blood sugar.

This makes apples a better choice than many other fruits for diabetes management and low-carb diets. Though portion size still matters.

Research shows eating 1-2 small apples per day only provides modest benefits for lowering HbA1c in type 2 diabetics. Larger intakes don’t seem to have additional impact.5

So stick within the recommended portion of half a small apple to obtain blood sugar benefits without overdoing carbs. Pairing with protein or fat can further help maintain steady, low blood sugar levels.

The Carb Counts Of Common Apple Products

Beyond whole apples, there are many popular apple products. Here are the carb counts for some common processed or cooked apple foods:6,7

Food Serving Net Carbs
Apple juice 1 cup 28.9g
Applesauce (unsweetened) 1/2 cup 14.7g
Dried apples 1/4 cup 33.2g
Apple pie filling 1/2 cup 26.2g
Baked apples 1 fruit (with skin) 20.8g

In general, processed apple products are higher in carbs and sugar than fresh apples. Stick with whole apples or unsweetened applesauce if lowering carb intake. Avoid drinking apple juice.

Typical Keto Macros For Half An Apple

The standard keto diet calls for consuming around 5-10% carbs, 15-30% protein, and 60-80% fat from your total daily calories.

If you are following a keto diet with a net carb limit of around 50g per day, here is an example breakdown of how half a small apple could fit into these macros:

Macronutrient Grams Calories Percentage of Calories
Net Carbs 5.7g 23 kcal 6%
Protein 7g 28 kcal 8%
Fat 8g 72 kcal 21%
Total Calories 123 kcal 100%

As you can see, half a small apple contributes 23 calories from net carbs (6% of calories), keeping it low enough to fit into a keto diet if the rest of your food choices also adhere to the macros.

On non-keto low-carb diets with up to 100g daily net carbs, an apple is easy to accommodate within your limits.


To summarize, half a small apple weighing around 100 grams contains approximately 5.7 grams of net carbs. The exact amount will vary slightly depending on apple size.

Despite being a fruit, apples are relatively low in sugar and carbs compared to many other fruits. Their fiber content reduces blood sugar impact.

When eaten in moderation and balanced with protein and fat, apples can be included as part of a healthy low-carb or keto diet. Stick to small portions and pair apples with low-carb mix-ins to stay within your macros.

Now that you know how many net carbs are in half an apple, you can enjoy this nutritious fruit without worrying about it derailing your low-carb diet!
