Precisely - 4 days. I said 3 weeks. Notice what the author is
talking about - a very short term carb deprivation. We were talking
about a long term low carb diet on which the need for glucose
drops even further, to the 40gm per day for all tissues, if I
recall correctly. (Again, this is without high intensity
exercise).

Yes, if you are a type I diabetic. If you can still make insulin
this is NOT a problem as the body will limit the amounts of
ketones it will produce. Either the author is unaware of this,
is trying to cover his legal butt, or intentionally trying to
scare people.
