if so what should it be?
Seems like a good chance to gather data (perhaps yearly) on a few hundred or more people who generally stick to this 'fad' (I'm kidding) diet. Even though macronutrient ratios are argued about, most people generally steer clear of gluten, legumes, milk, and refined sugars.
Perhaps a basic height/weight might be a good place to start but maybe include lipid panel numbers or something?
