Hiya,
Personally I cannot lowcarb AT ALL as I do get hypoglyceamic episodes.
if I cut out carbs, even a bit, I start to sweat and get dizzy, then get a headache ( acute, like someone sticks a knife in my head) and chest pain and have fainted a few times as well.
If I then eat some carbs, I feel better but can still feel "out of it" for the rest of the day, and sleep poorly.
For me, GI diet (eating carbs, but making sure they are wholegrain, such as oats, brown rice etc.) is the key.
Low carbing is not for people with sensitive blood sugar.
people who can lowcarb successfully, have a certain level their blood sugar just doesn't go below.
Search for hypoglyceamia. It is not a disease, it just means you have to "manage" your blood sugar. It is the opposite of being diabetic, if that makes sense.
