High ketones are a sign of inefficient fat burning. If you have high ketone readings or if you can easily produce high ketone readings, you are not 100% fat adapted. Of course, if you are on a Zero Carb diet, you are in ketosis all the time, but our ketone levels become stable, just like our blood sugar levels.
The science on this is very new and very misunderstood. Dr Phinney has done the most research on it, but even he is misunderstanding. He thinks elevated ketones, in a target range, are a great thing and we should strive to be in “nutritional ketosis”. I wish he would try Zero Carb, so he can see what happens when people eat the human optimal diet, meat, with no restrictions or counting macros.
