Keto Net Carbs

For someone in the US or Canada, where carbs include fiber, just track fiber (which IMO people should anyway, especially if doing low carb) and subtract the fiber from carbs. When I was ketoing I usually ate around 60 total carbs, but 25 g of fiber, so it came (on average) to around 35 net carbs, which is plenty low enough for keto.

I ignored sugar alcohols, didn't consume a lot, and didn't want to consume a lot, so to the extent my total carbs were actually a bit lower than stated I just considered that a bonus/extra cushion.

On the website you see 5 things: protein, fat, carbs, fiber, and sugar are the ones I currently track. (The fifth one is just because there's nothing else I care about.)

They can't do net carbs (which would mean automatically subtracting fiber from carbs, the same thing it's easy to do in your head), since it's an international site and many entries are from countries where fiber (fibre!) is not included in carbs, and subtracting them off again would be inaccurate. Better to place it on the user to choose net carb or total carbs (as defined in the US) entries. That said, I think there are scripts you can add that do it for you. For me, even when ketoing, it was really quite important to know my fiber and total carbs as well as net, for my own views on the type of diet I wanted.
