Net Carbs Formula:
| From: | To: |
Net carbohydrates represent the total amount of digestible carbohydrates in food, calculated by subtracting dietary fiber from total carbohydrates. This measurement is particularly important for low-carb diets like keto and Atkins.
The calculator uses the net carbs formula:
Where:
Explanation: Dietary fiber is subtracted because it's not digested and absorbed by the body, therefore it doesn't impact blood sugar levels or contribute to net carbohydrate intake.
Details: Calculating net carbs helps individuals following low-carb diets track their actual digestible carbohydrate intake, maintain ketosis, manage blood sugar levels, and make informed food choices.
Tips: Enter total carbohydrates and dietary fiber values in grams. Both values must be positive numbers, and dietary fiber cannot exceed total carbohydrates. Values can include decimals for precision.
Q1: Why subtract fiber from total carbs?
A: Fiber is indigestible and doesn't raise blood sugar levels, making it non-impactful for net carb calculations in most low-carb diets.
Q2: Are all fibers treated equally in net carb calculations?
A: For most dietary purposes, yes. However, some specific fibers like soluble corn fiber may have minimal impact on blood sugar and are sometimes treated differently.
Q3: What is a good daily net carb limit for keto diet?
A: Typically 20-50 grams of net carbs per day, but this varies by individual metabolism, activity level, and weight loss goals.
Q4: Should I count sugar alcohols in net carbs?
A: Most sugar alcohols should be subtracted from total carbs, but some (like maltitol) have higher glycemic impact and may need partial counting.
Q5: Is this calculation accurate for all foods?
A: This calculation works for most whole foods. For processed foods with modified fibers or sugar alcohols, additional adjustments may be needed.
