Surely you need the presence of free fatty-acids with glycerol to form triglycerides, and if the diet is very low in fats then this metabolic cycle is going perform differently for fat storage, even with elevated carbohydrates. Well this is my understanding and though quite possibly wrong (albeit oversimplified), but I assume you need elevated free fatty-acids and glycerol presence to do the deed, an imbalance of one of the other will adjust the propensity of triglyceride formation and storage, be that via low carb high fat, or low fat high carb? No?
One other thing I always worry about with stuff like this, is that if one day she decides that eating raw isn't the best idea, it is going to be a really hard for her to change with all the pressure of her website. I mean that in comparison to say Robb Wolf et al who tends to be quite verbal and open to softening on some issues (not gluten). But of course I am comparing not apples with oranges, but apples and beef steaks. I wonder if Durianrider and his fellow fruitiples don't even give themselves room to budge on some issues, and so lock themselves into ideology. I bit like a Veganehovah's Witness, or Paleoyper-Calvinist.
Also Robb has never dressed up like a watermelon or posted a bikini dance.
