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.
At the end of the day, you have to go with what works for you. We've all heard arguments for both sides of many dietary stories, arguments based on nutrition, ethics, evolution, anthropology, etc. But if something makes you feel sick, none of that really matters.But being more vegan/vegetarian is better for me.
