I feel better being ketogenic than getting my energy from glucose, but I didn't know that this was the theory behind it. that's the second thing I've learned from you today, @Merida ! at this pace I'm gonna be super smart by the end of the week! hahaWell, after a lot reading I found that some people lack the enzyme that transports glucose across the blood brain barrier. The CNS can use ketones for energy production, and they do not need that special enzyme to cross the blood brain barrier.
But being more vegan/vegetarian is better for me.
