I'm very busy paying my mortgage so this response and the upcoming studies are all that time will allow in this thread. >Agree. Just as natural. That's no reason to suspect humans beeing unable to >live on carbohydrates. Humans cannot, repeat, CANNOT live on carbs alone. They CAN, however live without them. Protein and fat are required to sustain human life. Carbohydrates are the only macronutrient NOT required to sustain human life. So they ARE unable to live on carbohydrates alone. I hope to post both studies by week's end.
