Now, the above reccomendations would seem pretty clear. I've made a dietary experiment on myself to test the 'eat less carbs + eat less proteins' points, or rather to optimize the quantitiy of carbs and proteins.
There are conditions that lead to a lack of carbohydrates. For instance a lack of fiber (provided in whole wheat bread and flax seed) in diet which can lead to pancrea and liver problems and diebetes. There are also carbohydrates that are recommended. For instance Paramahansa Yogananda said that maple syrup stimulated brain activity.
