“I am interested in a Ketosis meter, and a chart that would show what a health range is, along with blood sugar range, according to sex, age, and weight.”
The upcoming videos later today and in the coming days will present a lot of information about those details.
Generally speaking, a person enters ketosis at about 0.5, reaches optimum levels around 1.5, and extends the range during exercise and stress upwards to 3.0. Ketones become progressively undesirable beyond 3.0 until reaching the neighborhood of 10.0, where the onset of frequently lethal ketoacidosis occurs in Type I Diabetes patients and Type II Diabetes patients whose islets in the pancreas are not producing insulin.
In the meantime, there are currently at least two patient meter systems which combine glucose and blood ketone testing into one meter. Abbott laboratories offers the Precision Xtra blood glucose and ketone monitoring system. Nova Diabetes Care offers the Nova Max Plus.
