Healthy Weight and Optimal Fertility In Men and Women

Brittany Darling from Wholefood Healing Shares Why a Healthy Weight is the Key for Optimal Fertility in Men and Women.

Ensuring a healthy weight is a key factor for optimal reproductive health and fertility in both male and female partners. Infertility is defined by The World Health Organisation (WHO) as “the failure to conceive after 12 or more months of regular unprotected sex”. Approximately 10-15% of couples worldwide are considered infertile and data suggests that obesity is a material contributor to primary infertility (1). Weight management is an effective strategy for improving reproductive outcomes in couples having difficulty conceiving or maintaining pregnancy (2).

Obesity and an increased body mass index (BMI) contributes to female infertility by directly affecting the hormone regulatory axis from the hypothalamus to the pituitaryand the ovaries. Being overweight is also major component of insulin resistance, polycystic ovarian syndrome, amenorrhea (absence of periods) and anovulatory (absence of ovulation) cycles (3).

In men, increased body mass is implicated with disruption to the hypothalamic-pituitary-gonadal axis, increased adipose (fat cell) oestrogen production and reduced sperm concentration and motility (2).

Reaching an optimal weight for both partners is an effective and non-invasive way of improving fertility and pregnancy outcomes. Unfortunately, it isn’t always offered as an option. This is sometimes because of the narrow window for conception given increasing maternal age as well as concern of potential nutrient depletion if a restrictive approach is adopted prior to conception in the female (2).

Eimele’s (pronounced “a meal”), weight loss management system offers a 100% plant based, sustainable and effective approach to weight loss. Eimele’s meal replacement products supply balanced and complete nutrition by using ingredients sourced from whole foods with nothing artificial added. Each meal contains complex carbohydrates, adequate protein and essential nutrients including iron (25% RDI), calcium (25% RDI) and iodine, supporting you to your ideal weight while maintaining an optimal nutritional status. Achieving an optimal weight not only increases the woman’s chance of conception both naturally and assisted, but also reduces the risk of pregnancy complications including gestational diabetes, preeclampsia, and increased infant birth weight that can lead to birth complications (1).

As well as achieving a healthy weight, ensuring both partners have sufficient levels of nutrients is a key component of fertility (4). It is estimated that 30% of women of reproductive age are iron deficient (5). Iron is an essential mineral for almost all living organisms as it participates in a wide variety of metabolic processes (6). Iron assists in the transport of oxygen throughout the body and is required for adequate neurotransmitter production, immune function and is critical for early foetal brain development in utero. Ensuring adequate iron levels prior to conception is essential for fertility, optimal pregnancy and the future health of the infant (7).

Iodine is an essential mineral for the production of thyroid hormones. During the first trimester of pregnancy, maternal thyroid activity is increased to support the development of the foetus (8). Adequate iodine stores, prior to conception can mean the mother can adequately support maternal thyroid hormones formation and the development of the unborn child for the duration of pregnancy, without her stores running low (9). Therefore having sufficient iodine levels prior to and throughout pregnancy is extremely important for the mother and infant.

The National Health and Medical Research Council recommend a total daily iodine intake of 150 mcg per day for adults and 220 mcg per day in pregnancy (8). As iodine availability in food is fairly low, compulsory fortification of commercial bread with iodised salt was introduced toAustralian in 2009, as an effective way of providing adequate iodine to the general population (10). Unfortunately, those wanting to lose weight often take the “low carb” approach and are missing out on their daily requirement of iodine.

Eimele products are 100% plant based – with the ethos to eat as close to nature as possible to maximise the amount of high fibre, high protein, great tasting, low calorie foods in the individual’s diet. The Eimele range of products include a delicious range of porridges, soups and snack bars conveniently packaged in individual portions for hassle-free complete nutrition on the go.
