I'm interested in this, also! I will start marathon training in January and will be curious to how eating Primal will affect my endurance/energy levels during long runs.
I've been eating Primal for about 3 weeks now and seeing slow fast loss, and still able to keep up my exercise routine (running, spinning, mountain biking, Crossfit workouts, some treadmill sprints)
As for my carbs, besides vegetables- I eat sweet potatoes and Larabars
I'm trying my best this week to cut out dairy to see if that helps quicken fat loss
