Recent studies suggest that women who are trying to get pregnant can benefit from eating a healthy breakfast. It was discovered by Tel Aviv University and the Hebrew University of Jerusalem that eating a substantial breakfast increases fertility in women who experience irregular periods. What did the study investigate?
The study set out to understand if meal- times have an impact on the health of a woman with irregular periods due to Polycystic Ovary Syndrome. Currently, PCOS affects 6 to 10 percent of women. The researchers followed 60 women aged 25 to 39 over a 12-week period. Each of the women suffered from PCOS and had a body mass index (BMI) of less than 23. From there, researchers led by Professor Oren Froy, Professor Daniela Jocabovitz and Dr. Julio Weinstein divided the women into two groups; each was allowed to consume 1,800 calories a day. The only difference between the two groups was the time of day at which the women consumed their biggest meal. 30 of the women ate their biggest meal at breakfast while the remaining 30 ate their biggest meal at dinner.
The study concluded:
Women who ate their biggest meal at breakfast had decreased glucose and insulin levels (down by 8 percent), compared to the dinner group who showed levels that remained virtually the unchanged. Also in the breakfast group, researchers noted that testosterone levels were down by nearly 50 percent. But the most interesting was that women were ovulating at a much higher rate when they had their biggest meal at breakfast.
Of the findings, Froy said that the research “clearly demonstrates that indeed the amount of calories we consume daily is very important, but the timing as to when we consume them is even more important.”
