Low-Carb = Poor Memory

Extra pounds may not be the only thing you lose if you follow a low-carb diet; you might also be diminishing your memory, according to researchers at Tufts University. Memory tests given to low-carb dieters have shown that cognitive functions were significantly worse after just one week of severe carbohydrate restriction. Carbs are broken down into glucose, which is the brain's preferred source of energy. The lower the carbohydrate intake, the less brain fuel available.
