Carbs in Apple: The Quick Answer
Apple contains 12.7g of net carbs per 100g, calculated by subtracting 2.1g of dietary fiber from 14.8g of total carbohydrates. With 61.0 calories, 0.2g protein, and 0.1g fat per 100g, it is classified as Moderate Carbs for carbohydrate content.
Net carbs — not total carbs — are what matter for keto and low-carb diets. Only net carbs raise blood sugar and affect insulin, which is why tracking them accurately is key to staying in ketosis. Use our Keto Macro Calculator to find your daily net carb limit based on your body and goals.
Is Apple Keto Friendly?
Apple has 12.7g net carbs per 100g, which is moderate. It can be included occasionally on keto if portions are controlled and the rest of your day's carbs are kept very low.
How Net Carbs Are Calculated
Net carbs are calculated by subtracting dietary fiber (and sugar alcohols, if present) from total carbohydrates: Net Carbs = Total Carbs − Fiber. For Apple: 14.8g − 2.1g = 12.7g net carbs per 100g.
Dietary fiber is subtracted because it passes through the digestive system without being absorbed as glucose. It does not raise blood sugar or trigger an insulin response, making it irrelevant for carb counting on keto and low-carb diets.
