Big breakfast diet may boost fertility for women with PCOS


Women with polycystic ovarian syndrome who control insulin levels can improve their fertility by increasing calories at breakfast and decreasing them at dinner. Most women with PCOS are typically “insulin resistant,” meaning that their bodes produce too much insulin. Eventually the excess insulin goes to the ovaries and prompts the production of testosterone. The increased testosterone decreases fertility.

Big breakfast of 980 calories, lunch of 640 caloris and dinner of 190 calories

Prof. Daniela Jakubowicz who led the research at the University of Tel Aviv, explained that doctors often suggest weight loss for overweight women with PCOS in order to manage their insulin. However, many women with PCOS are not overweight. For this study, Jakubowicz took two groups of women with PCOS and normal BMI and had one group eat a big breakfast and the other group eat a big dinner. The breakfast consisted of 980 calories and was the largest caloric meal of the day. The other group ate a 980 calorie dinner with other meals being calorically smaller. Both groups ate 1800 calories a day. After 90 days their insulin, glucose and testosterone were tested. Their ovulation and menstrual cycles were also analyzed.

Results are promising

The results showed that neither group experienced a change in BMI, but the big dinner group still had high levels of insulin and testosterone. The big breakfast group had 56% less insulin resistance and a 50% fall in testosterone. The big breakfast group also reported a 50% rise in ovulation rate.

The diet addresses all kinds of symptoms, not just infertility

Prof. Jakubowicz explained that the big breakfast meal plan follows the body’s metabolic cycle. The diet promotes insulin management. Even if a woman is not trying to get pregnant, the diet will help with other symptoms of PCOS including unwanted body hair, oily hair, hair loss and acne. There is also the added benefit of preventing type-2 diabetes.
