How about this... none of you really no anything, there have not been any longitudinal studies done on LC diets, therefore longterm and any other side effects of the diet in question can not be proved or disproved. You can read and quote all of the studies you want, but until there are LT studies and those studies are replicated we are all SOL. That is why we all have to do what we think is right and what our bodies are telling us. Anyone that knows anything about research would be questioning about 90% of the studies that have been done. They are crap.
