Humans need carbs. The brain runs off of glucose. It's as simple as that.
This blood sugar is obtained from carbohydrates: the starches and sugars you eat in the form of grains and legumes, fruits and vegetables. (The only animal foods containing a significant amount of carbohydrates are dairy products.)
Too much sugar or refined carbohydrates at one time, however, can actually deprive your brain of glucose ? depleting its energy supply and compromising your brain's power to concentrate, remember, and learn. Mental activity requires a lot of energy.
Now...The carbs won't put on weight UNLESS you don't fucking exercise! The problem with people who go on fad diets is that they rarely get off of their ass and do some cardio/weights/swinnimg/sports.
If you burn the carbs, you don't put on weight. It's that simple. Does anybody ever wonder WHY Atkins himself had a heart attack?
