BMI may be a significant factor in fertility weight loss, as an increase in BMI in the male by as little as three units can be associated with infertility 1. Obese men are three times more likely to exhibit a reduction in semen quality than men of a normal weight 2. Several studies have demonstrated that an increase in BMI is correlated with a decrease in sperm concentration 3, 4, and a decrease in motility 5. Overweight men have also been found to have increased DNA damage in sperm 6, 7.
Sadly obese women have a higher rate of recurrent, early miscarriage compared to non-obese women. In a systematic review, Boots & Stephenson reported a miscarriage rate of 10.7% in women with a normal BMI, which was significantly lower than that of 13.6% in obese women (OR: 1.31; 95% CI 1.18-1.46) 8.
The negative effects of obesity on fertility in women may be reversible. Clark et al. found that after losing an average of 10.2 kg, 90% of obese previously an ovulatory women began ovulating 9.
Sometimes difficulty in losing weight could stem from an underlying health complaint. Thus there is no such thing as a one size fits all program when it comes to weight loss. If you have irregular menstrual cycles, low energy, unexplained weight gain acne or male pattern hair growth, it will be important to have blood tests done to see check for an underlying cause to your excess weight.
Regular monitoring with BIA (bio impedance) screenings to ensure you are losing weight correctly (through fat loss instead of muscle or fluid loss), allows Kylie to adjust your program as your health improves. This is a non-invasive, painless and quick screening, giving you a breakdown of your body composition.
It is based on a technology with over 2000 published scientific studies behind it.
REAL FOOD is recommended as your weight loss “medicine” along with nutritional and herbal support to ensure elimination of all toxins and balance of blood sugar levels. No meal replacements, starving or calorie counting is needed.
Even if you are suffering from thyroid concerns or polycystic ovarian syndrome you can lose weight. All that is required is a healthy attitude and desire to lose weight and it can be achieved.
