Hmmm...looking at Yogabare's poll, it's possible that ~20% of us stay under 50 gm carbs a day long-term, so your chart doesn't really work for me. Nice looking, though!
The chart does not show up for me. Hmm.
Stumbled into Primal due to food allergies, and subsequent elimination of non-primal foods.
Start Gluten-Free/Soy-Free: December 2012; start weight 158lbs, Ladies size 6
Start Primal: March 2013, start weight 150lbs, Ladies size 6
Current: 132lbs, Ladies size 2
26lbs lost since cutting the crap.
Mark's chart helped me immeasurably when I first started Primal. It was one of the first things that "clicked". Realizing that they eat far too many carbs is a good first step for those on the SAD diet. Primal carbs are a different story, but it's a good starting point for someone just learning about this stuff.
