I still want to know what NED means.
But I don't see why one couldn't be a high level primalist.
It requires you to have more carbohydrates in your diet than I would ever eat.
Depending on the type of exercising/activity you train for.
Though if you eat berries it's quite easy to get a lot of micros and carbohydrates at the same time.
Some people have been suggesting sweet potatoes and other starches for athletes as well. I wouldn't know how that works because I don't have access to any sweet potatoes.
