Ketone level is a gradient. It's never "on" or "off" until we draw an arbitrary line. At the 50g~100g level I suspect you'll flirt with higher ketones overnight then decrease them after the first meal.
It is advised to take less than 50g carb a day to stay in ketosis.
Also, as far as I know, it is said that brain needs 100~150g carb a day.
Now, what happens if I take 50 ~ 100g carb a day which will not induce ketosis but also not enough to fuel brain without ketone?
Then, what exactly is Ketosis? Does it just mean that the state in which ketone is constantly generated?
Also, it is also said that a few days to a few weeks are need to be adapted to ketone.
Is there any adverse effect using ketone as a brain for fuel when not in ketosis (so not adapted to ketone)?
The state of ketosis is when your body is primarily utilizing ketones for fule however, and only utilizing the bare minimum of glucose necessary for survival. The more fat you costume and the less carbs, the more likely tht you will enter into this state. Different people have to restrict carbs more or less than others to hit this state and your level of physical activity can also make it more or less difficult for one to enter into a state of ketosis.
BOHB level of 0.5~3.0 mmol/liter. Average carbohydrate intake keeps people around 0.1~0.3. (For some reason people enjoy measuring acetone in urine but it's not the same thing).
As I understand it ketone adaptation is mostly a concern for athletes who initially suffer reduced skeletal muscle performance on a VLC diet (light-moderate active people won't notice it). The brain is always capable of burning both glucose and ketones in whatever proportion is available at the moment. In fact all SCT and MCT fats we consume (butter, coconut) become ketones and find a good home regardless of our carb intake.
A clear explanation on wiki Ketosis - Wikipedia, the free encyclopedia
When I'd had enough of the grain and starched based 'diabetic eating for health' diet (eating for health, my ass!) my weight was 242.5 lbs. On starting primal- 18th April 2013 weight : 238.1.
27th July 2013. weight after 100 days 136.9 weight lost 101.2lb ; that's 105.6lbs since I stopped the 'diabetic eating for health'

People seem to be misinformed. Oxidation of glucose is the main source of energy for brain function, which is why there are many transporter isoforms for the brain, whereas ketones are limited by transport capacity.
