Keto: What Fits, and What Your Limit Changes
Almost every keto page on the internet gives you a list of allowed and forbidden foods. That is the wrong shape for the rule. Keto is a number — a daily net carb limit — and whether a given food fits depends on your number and your portion, not on which list someone put it in.
Net carbs are total carbohydrate minus fibre. The subtraction is standard practice because most fibre is not absorbed as glucose; sugar alcohols are the genuinely contested part, and we say so on the pages where they appear. Most people run somewhere between 20 g and 50 g of net carbs a day, and that range is wide enough that the same food is a clear yes at one end and a clear no at the other. Which is exactly why a list cannot answer it.
