PB and anyone else on this thread that wants to chime in - I have a question about ketosis and carb flu that I'd like to ask (don't mean to hijack your thread). I never experienced anything like carb flu and switching to primal was incredibly easy for me. I don't know what my pre-primal carb levels were but probably pretty bad - my meals were 50% giant salads with a little protein and fat, 30% "healthy" carbs (fruit, whole grains), and 20% fast food for convenience with occasional candy bars. Plus too much coffee "for energy" daily.
When I started primal, I kept carbs at or below 100g/day, then cut to 50g/day and saw increased weight loss (15 lbs in about 6 weeks). Currently I've been experimenting with shooting for an average of 50g instead of an exact number. I do count calories and stay around 1200/day net of exercise. Since I started varying carb amounts by day, I've lost a few more pounds but not enough to definitely demonstrate that this is a significant factor.
So I guess my questions is: If I never had carb flu, does that mean I'm still eating too many carbs for me? I would welcome your opinion.
