Carbs in Bread: The Quick Answer
Bread contains 17.6g of net carbs per 100g, calculated by subtracting 0.0g of dietary fiber from 17.6g of total carbohydrates. With 252.0 calories, 16.4g protein, and 12.9g 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 Bread Keto Friendly?
Bread has 17.6g 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.
Best Low-Carb Swaps for Bread
Bread is high in carbs. If you're eating low-carb or keto, these swaps deliver the same satisfaction with a fraction of the net carbs.
| Instead of | Try this | Why it helps |
|---|---|---|
| Two slices of white bread (~25g net carbs) | Lettuce wraps (romaine or butter lettuce) | Near-zero carbs — works for deli meat, tuna salad, burgers |
| Toast with eggs | Cloud bread (eggs + cream cheese) | Fluffy egg-based bread, ~1g net carb per slice |
| Sandwich bread | Almond flour bread (homemade or store-bought) | ~3g net carbs per slice vs ~13g — same sandwich experience |
| Bread for dipping in soup | Sliced cucumber or celery sticks | Surprisingly satisfying for scooping thick soups or dips |
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 Bread: 17.6g − 0.0g = 17.6g 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.
