Bigger Belly, Smaller Brain
Another reason to skip the pasta: Being fat causes your brain to shrink, say University of Pittsburgh researchers. Scans of 94 older people revealed that the brains of the overweight were 4 percent smaller than those of healthy-weight people; in the obese, they were 8% smaller. Excess weight restricts blood vessels and lung capacity, depriving the brain of oxygen, says study author Paul Thompson PhD. The result is a prematurely aged brain.
