About this calculator
Total carbs vs. net carbs: total = all carbohydrates including fiber. Net = total minus fiber minus half of sugar alcohols (FDA convention used by keto trackers). Strict keto: <20-25g net carbs/day. Lazy keto: <50g. Standard low-carb: <100g. The FDA Daily Value reference is 275g/day on a 2,000 kcal diet (55% of calories from carbs). For diabetics, dividing carbs evenly across meals (45-60g/meal) helps blood-sugar control.
