Researchers at Tufts University found that when dieters stopped eating carbs, they performed worse on memory-based tasks than when they reduced calories alone. When they ate carbs again, dieters' memories returned.

They think it's because the brain uses glucose as fuel, but it can't store it. Carbs are broken down into glucose that reaches the brain in the blood stream. Atkins and other low-carb diets reduce the brain's source of energy, and cognitive abilities decline.

Brain function may decline the longer a person is on a low-carb diet say researchers. But brains go right back to normal when carbs are re-introduced.

My brain works better, and I have more patience with my kids, when I get the right amount of protein, veggies and carbs each day--not too much and not too little.
