Hi Minimoo
The point you make about the brain needing carbs I'm afraid is a bit misleading. The brain needs glucose specifically and this can be obtained directly from glucose in the blood or glucose delivered form the liver and this can be indirectly derived from fats and proteins. The link you provide i.e.
http://www.fi.edu/learn/brain/carbs.html is also misleading. It says, correctly that the brain needs glucose but quite incorrectly implies this only comes from carbs derived from starches and sugars ignoring what the liver can deliver. It's this misleading info that helps the 'professionals' go on about needing to eat carbs to keep the brain working which is not correct; you need to eat 'food' to keep your brain working.
true, but also misleading
bother, i cant copy a table in here, right, i dont expect anyone to read this so ill quickly add the summery
Clearly the below represents a pretty drastic range of carbohydrate requirements, depending on the specifics. For a typical male with 160 pounds of lean body mass, daily carbohydrate intake could range from the physiological requirement of zero grams per day to a near maximum of 1120 g/day during a carb-load. Which makes it no wonder that people are confused.
Simply, the question “How Many Carbohydrates Do You Need?” has no singular answer. The goals of the person, the amount and type of activity, their individual needs (e.g. insulin sensitive vs. resistant, whether or not they function well in ketosis or not), their individual goals all determine how many carbs are ideal in the diet.
