Check carbs against a low carb goal.
Low-carb plans are almost always written in net carbs: total carbohydrate minus fibre, because fibre is largely unabsorbed and has little effect on blood glucose. Subtracting fibre first and then comparing against your goal is what tells you whether the day worked. The tier reflects the conventional bands — up to about 20 g net is the ketogenic range, up to 50 g very low carb, and up to 130 g moderate — and the calorie share puts the same figure in the context of the whole day.
Net carbs
Net carbs = total carbohydrate - fibre
Carbohydrate share
Share = (net carbs x 4 + fibre x 2) / daily calories x 100
These figures are population-average estimates for general planning only and are not medical or dietetic advice. Individual energy and nutrient needs vary widely with body composition, activity, medication and health status. Consult a qualified health professional or registered dietitian before making significant changes to what you eat, and especially if you are pregnant or breastfeeding, are under 18, or have a medical condition or a history of disordered eating.
Partially. Erythritol is essentially unabsorbed and usually subtracted in full; maltitol is roughly half absorbed and should not be. This calculator only subtracts the fibre you enter, so handle sugar alcohols by adjusting the total you type in.
It means you came in under your goal, which is on plan. Very low intakes sustained for long periods warrant professional oversight, particularly if you take glucose-lowering medication.
Because part of it is fermented in the colon into short-chain fatty acids the body can use, which is why it is priced at about 2 kcal per gram rather than zero.
