As the article says, ketosis is not a bad metabolic state for most people (there are a few exceptions, like when you're taking certain medications that can cause kidney stones). Ketoacidosis is a bad metabolic state, but that is something altogether different.
ummm, do you know what ketosis means? Ketosis is a benign by-product of FAT BURNING. In order to LOSE weight one must burn fat. Would you agree with that statement?
Now, whether one is on a high carb, low carb or booger diet, if they are burning fat, they are in ketosis. If one does not burn fat [a healthy happenstance in most circles, but i guess not this one] then where does all that fat go? hmmmm
Perhaps it just stays in the body and clogs the arteries and creates heart disease?
Many often confuse ketosis with KETOACIDOSIS, which is a very dangerous condition for disbetics. However, noone serious would claim that fat burning is harmful. [unless they don't know what they are talking about]
