Intermittent Fasting and Infertility in Women
The same study conducted by Heilbronn LK, “Glucose Tolerance and Skeletal Muscle Gene Expression in Response to Alternate Day Fasting,” discovered an improvement in insulin intake for men, but that intermittent fasting can worsen blood sugar control in women. Blood sugar imbalances can cause high production of the insulin hormone, which in turn can impact weight, adrenaline, low energy, hunger, cravings and anxiety. Due to a lack of blood sugar control, women’s health and fertility rates are much more negatively affected, and it can worsen their experience of the intermittent fasting side effects (see overall side effects of intermittent fasting). Your hunger and cravings will be much greater than a man’s experience of these symptoms, should you choose to fast.
Blood sugar control can escalate to fertility issues for women. How? Sugar can cause weight gain. Weight gain is already considered negatively impactful on fertility, but it can also lead to other health complications that affect fertility, such as diabetes and obesity. Weight gain can also increase oestrogen production, thus creating hormonal imbalances. Hormone imbalance is suggested to hinder fertility. This can lead to high levels of insulin, which encourages more oestrogen to be produced, and the cycle continues until the body has an oestrogen dominance which affects your menstrual cycle.
Other studies of intermittent fasting (tested on female rats) found that it can cause missed menstrual cycles, infertility and can cause the rats to become masculinised. Anecdotal reports of women on the intermittent fasting diet concluded that it can encourage menstrual cycles to cease altogether (amenorrhea), and only resume once the women have stopped fasting and returned to their usual diets. This evidence has proved a link between intermittent fasting and infertility in women, so if you are looking for a healthy diet that is compatible with fertility, this may not be the right regime for you.
