Wanna give birth to a son? A hearty breakfast laced with sugar appears to boost a woman’s chances. The odds of having a male baby also sharply increased for women who had at least one bowl of breakfast cereal each day compared to women who ate less than or equal to one bowl a week. The study (published in Proceedings of the Royal Society B: Biological Sciences) found that a low-calorie diet is more likely to yield a girl baby.
