Men have more willpower than women when it comes to resisting food, a small new study suggests.
"We didn’t expect such striking differences between males and females," study co-author Nora Volkow, director of the National Institute on Drug Abuse, tells ScientificAmerican.com. "Men were able to inhibit their desire for food . . . and women weren’t able to do so."
Scientists had 13 women and 10 men who had fasted overnight look at, smell and taste – but not dig into — goodies like pizza, burgers and cake. They then told the subjects to practice "cognitive inhibition" (read: to try to convince themselves they weren't really hungry) and measured their brain activity using positron emission tomography (PET) scanning. (PET scans measure increases in blood flow linked to brain activity.)

Last spring, British researchers hit on what seemed like a startling finding: Eating lots of cereal before getting pregnant was associated with conceiving a son. Never mind that sex is determined by chromosomes in the father's sperm. The apparent link between gender and diet generated buzz.
But it turns out cereal may not be your lucky charm if you're hoping for a boy.
Today, another group of scientists is disputing that study, charging that its analysis was flawed and its conclusions due to chance. The researchers—from the National Institute of Statistical Sciences, Cornell University and New York Medical College—report their findings in today's Proceedings of the Royal Society B, the same journal that published the cereal study last April.
