Formula
net carbs = total carbohydrate − fibre − sugar alcohols (carbohydrate = 4 kcal/g)= 17
Note
Simplified nutrition model using standard reference constants (protein and carbohydrate 4 kcal/g, fat 9 kcal/g, alcohol 7 kcal/g, 1 kg of body fat about 7700 kcal, salt to sodium factor 0.393). Real energy needs and body composition changes vary between individuals. This is not medical, dietetic or nutritional advice; consult a qualified health professional before changing your diet.

How are net carbs calculated?+
Net carbs are calculated by subtracting fiber grams (and often sugar alcohols, depending on the convention used) from total carbohydrate grams, on the reasoning that fiber and certain sugar alcohols have minimal impact on blood sugar compared to digestible carbohydrates.
Why do people on low-carb or keto diets track net carbs instead of total carbs?+
The net carbs approach assumes fiber is not significantly digested or absorbed and so doesn't meaningfully raise blood glucose or count toward carb-restricted goals, allowing higher-fiber foods to be included more liberally in a low-carb diet plan than total-carb counting would allow.
Is the net carbs concept the same everywhere?+
No — it is not a standardized regulatory term in most countries, and different sources handle sugar alcohols differently (some subtract them fully, others partially, others not at all), so treat 'net carbs' as an estimate that can vary depending on which convention a label or calculator uses.
Do all sugar alcohols affect blood sugar the same way?+
No, some sugar alcohols like erythritol have minimal blood sugar impact and are reasonably excluded from net carbs, while others like maltitol are absorbed more significantly and can raise blood glucose meaningfully despite being commonly subtracted — this is a known limitation of the simple net-carb formula.
Should people with diabetes rely solely on net carbs for blood sugar management?+
Not exclusively — because sugar alcohol impact varies and the net carbs concept isn't strictly standardized, individuals managing diabetes should also monitor actual blood glucose response to specific foods rather than assuming net carbs alone fully predicts glycemic impact.
