Re: which came first, the allergies or the disease? (edited)

I haven't read much about atkins diet but I know that introducing diet on atkins diet was a ketogenic, mostly all meat.

I am sorry for your mother, I really am. To find success with one diet but later see failure from the successful diet is disappointing. It's very hard for me to know why it caused these problems for her. I am just a new fish in this.

Raw meat is neutral and cooked meat is slightly acidic if we want to relay on the foods ph. Body balances it's ph with calcium. If calcium is deficient it takes it from the bones(I might be wrong here). Is your mother diabetic because if she is she might have developed ketoacidosis (ketogenic diet does not cause it). From wikipedia: "The presence of high blood Sugar levels (hyperglycemia) caused by the lack of insulin can lead to further acidity in the blood."
Maybe HV can help here: If she was diabetic and consumed high fat diet then cheating with sugary things would cause high blood Sugar and insulin resistance from the fat? This leads to ketoacidosis.
