no its not bro science.. YOUR BRAIN NEEDS GLUCOSE EVERYDAY.. if your body has 0 glucose it converts PROTEIN to glucose, its science, go and search for it on google
your brain does need glucose daily.... if you have no glucose where do u think your body gets it from?
the brain CAN burn fat for energy, but it still needs a little amount of glucose regardless..
You also use glucose in the muscles if you do any kind of work out/ etc..

and i used that link because it SUPPORTS Low carb so u dont bitch.. im also a low carber..
"One of the myths spread about the low carb diet is that your brain needs carbohydrates to function well. Actually your brain needs just a small amount of GLUCOSE - which is provided by protein quite easily."
no need to argue with u.. but spend 5mins and u'll see your body converts protein to glucose.. didnt you learn this in grade school?
and this is the reason why body builders on low carb worry about muscle catabolism and end up eating carbs pre/post workout.. otherwise your body will just burn protein and convert it to glucose to feed the burned out muscles..
