I totally agree that it is possible to overeat on any plan and therefore not lose weight. I am the one who wrote the calorie counting threads pointing out this reason for failure in some Primal eaters. Remember?
I'm interested in optimal health but for many people here that means losing weight. If a plan is going to displace a lot of nutritionally dense foods with calorically dense but nutritionally sparse ones, that is cause for concern. You, yourself stated this as the reason you don't plan to start eating table sugar. See, we are agreeing.
