Does anyone know why net carbs theory does not apply to CAD/CALP?
or does it?

carb addicts are sensitive to all carbs. (supposedly)

Personally I think the whole net carb thing is just a marketing ploy for companies to sell us products we shouldn't be eating by trying to convince us that it's not harmful.

Carbohydrate addicts (CAs) are insulin reactive to all carbs, even fiber and sugar alcohols. We're even reactive to artificial sugar (AS). Therefore net carb theory doesn't work for us. That's why some of the foods allowed on Atkins are not allowed at CMs. That being said, some CAs are less sensitive than others and can tolerate more carbs/AS at CMs than others. The place a lot of CAs trip on these products is that many just think they aren't sensitive because they're not aware of cravings. But insulin levels can still be affected and stall weight loss even if cravings don't result. That insulin affect can also affect hunger and the balance of RMs.
