Strong statement. The brain can run on ketones just fine, it’s constantly titrating energy consumption from different sources. You might say the brain uses glucose first as a priority, but that is also true for alcohol.
Fat can be broken down into glucose, though
Not really a complete statement, gluconeogenesis requires more inputs then just fat, so of the glucose produced only 15% of the energy is coming from fat.
There is a 1972 paper that demonstrates normal functioning after prolonged fat adaptation, it’s a great read, but this specifically speaks to brain glucose utilization - https://doi.org/10.1172/JCI107095
Note how I said it can be converted to glucose. Note how all you did was describe how it can be converted to glucose. Nowhere did I say that process took nothing. Nowhere did I say it needs only glucose.
Just like your car doesn’t only need gas to function, and can technically ‘run’ on other things like pure alcohol.
