Don't confuse "
dietary ketosis" which is quite safe and natural and "
diabetic ketoacidosis" which is very dangerous, and can occur when someone (usually a type 1) has both very high glucose levels and very low insulin levels; their body then starts breaking down fat and produces ketones, but in a completely uncontrolled runaway manner, which results in a dangerous build up of acids in their blood which may actually be fatal.
There is actually a lot of confusion even amongst medical professionals about the two conditions.
If you are eating a very low carb diet you'll probably end up in ketosis but you'll have (or should have) both low ketone levels,
and low glucose levels too so
shouldn't ever have a problem - it's an absolutely normal condition and young breast fed babies are naturally in a state of ketosis. But you obviously need to be fairly sensible about things, and make sure that you're eating adequate fat n place of the previous high carbs, for your energy. It's certainly not a case of the higher ketone levels the better!
This graph will show you the big difference between the two conditions - people in dietary ketosis should be safely at the lower green end and no-one should want to be in the red!
