Your brain runs on glucose.
'...In a new study published in The Quarterly Review of Biology, scientists argue that carbohydrate consumption - particularly starch - has been instrumental in the evolution and expansion of the human brain over the past million years.
According to Harvard's School Of Public Health, the healthiest sources of carbohydrates are unprocessed or minimally processed whole grains, vegetables, fruits and beans.....

'....Neurons, which use twice the energy as any other cell type in the body, run almost exclusively on glucose. They don't run on protein and fat.* Moreover, because neurons aren't able to store glucose as glycogen as other cells in the body do, they must receive glucose in constant supply...That's glucose in amounts that could not possibly be supplied by any abundance of meat eating....
.....Peter Ungar, distinguished professor and chair of anthropology at University of Arkansas, who was recently named a fellow of the American Association for the Advancement of Science, what his take was on the role of meat eating versus carbs in human brain evolution. He wrote back, "Even the staunchest meat advocates recognize that protein and fat cannot power the brain – and we lose much of our gluconeogenesis capabilities at weaning. The argument is that meat eating provided the calories needed to power other parts of the body, freeing available carbohydrates to focus on the brain… Even in that case, it’s carbs, not meat that powers the brain......'
