Mark had a post recently where he said he didn't understand where anybody got the idea that the Primal Blueprint was a high fat, gorge on all the fat you can eat, low carb diet. He said that you can eat carbs if you are active. The only problem then is that he defined active as being fairly extreme, whereas lifting weights and walking most of the time he didn't consider active enough to eat potatoes and starchy things. I think that was a mistake on his part.
Mark's message IS a little confusing. Hopefully he is part way toward re-examining his message, maybe altering it a little. I have no doubt that low carb can help a lot of people (carbs make some fat people fat, but they don't make thin people fat). I also have no doubt that eating lots of starchy roots and tubers is fine for most people, even people who aren't extremely active.
Anyway, to the OP, if you didn't find cutting out grains and crappy vegetable oils to suit you, then rock on.
