I am sure it is very possible to eat too few carbs. Even 100 grams is much lower than what the "normal" person consumes. The body does need other fuels. Like a car needs gasoline but it also needs a coolant and motor oil to run efficiently. We can think of fats as the fuel, water as the coolant and motor oil as the carbohydrates. Now what happens if you never add motor oil to the car?

We have the concept if a little is good then more must be better, or if less is good than fewer must be better ( as with atkins ), which is not the case. This is why we are supposed to gradually incorporate more carbs into our diet. This is the way I think. Even though one can stay on induction for a much longer period of time than the minnimum 2 weeks, you don't want to exhaust the body.
