I'm interested what people know about 'net' carbs and ketosis. I'm not all that savvy on this stuff. I'm looking at a package of chia seeds, which says it's got 16 grams of carbs per quarter cup include 14 grams of fiber. On the Web, I see 'net carbs' calculated in this case as total carbs in grams minus fiber in grams: 16 - 14 => 2. Curious if ketosis occurs when you keep these 'net' values below 20. Another way of asking this is: Is the idea of 'net' carbs legitimate, when talking ketosis? Can I eat up to 20 grams of net carbs and have a reasonable expectation of ketosis, even if the 'total' carbs were 10 or 15 times the 'net carbs'?
