Why a day-level comparison is more useful than a single-product claim
A front-of-pack “net carbs” claim can make one product look keto-friendly, but most users do not live on one product in isolation. A stricter keto day can be thrown off by several moderate differences adding up. That is why a total carbs vs net carbs comparison calculator is useful: it measures the whole day rather than one marketing headline.
This is especially relevant for users trying to keep carbs low enough for nutritional ketosis, weight-loss keto, or a very low carb routine where the daily ceiling is already tight. A difference of a few grams on one serving may not matter, but the daily gap between total carbs and net carbs can become large surprisingly quickly.
