Not critical as such so much as concerned. We dont have all the info and can only go with what info you provide and then guess how to help. Eating primal is not just about vlc or zc. in fact I dare say that is not it at all. Mark suggests for weight loss that 50 to 75 g carbs a day be your target for a reason. So your body can learn to balance its hormones and nutritional needs.
Going vlc works for some folks definitely does not for me. Folks are all over the map on this but really is it healthy to do vlc/zc long term? I doubt it. I hope such a fast reintroduction of starches does not make you miserable 'cause man it would ruin my day.
The whole point of going primal is to live with optimal health and your hormones do require that you eat a good supply of balanced nutrition. I cant do that VLC, maybe you can.
I generally dont criticize folks but I do try to suggest caution and slowing down.
Hope this works for you.
