Weight Loss and Male or Female Fertility

Will I increases my chances to conceive if I gain or lose weight?

Well, let's look at some studies. In a DAnish Study published in Fertility and Sterility in Oct 2004, after looking at the reproductive hormones and semen quality of 1558 Danish men, they found that high or low BMI (Body Mass Index) was associated with reduced semen quality.

In several studies including one from a place in Germany that I can't pronounce :) reports that high or low BMI in women can have a negative impact on IVF outcome leading to decreased chance of pregnancy.

Keeping these studies in mind then, we want to find our health weight range which according to the BMI is 18.5-24.9. You can calculate your own BMI by going to http://www.cdc.gov/nccdphp/dnpa/bmi/calc-bmi.htmTherefore at our clinic I stress slow steady healthy weight loss or weight gain in some cases.

Think about it, rapid weight loss like that which is purported in some of the over the counter weight loss products or even some of the physician's assisted programs, won't accomplish what you are looking for. Losing weight quickly is also associated with diseases such as cancer.

Remember, you want to keep the body OUT of stress mode because when our body is in stress mode, reproduction goes on the back burner.Starting with a low glycemic index (www.glycemicindex.com) along with exercise is a good approach. Eliminating excess sugar from your diet and all the processed carbs is important. There are good carbs out there that burn slowly in your system (check out the GI database on www.glycemicindex.com) versus the convenience foods that have high amounts of sugar or burn quickly in our system shooting up glucose and insulin levels. These low gi carbs should always be accompanied by good protein and good fats.

Protein is important. And I recommend to stay away from soy products unless they are fermented such as tempeh, miso, natto, and some soy sauces. Soy has been shown to negatively effect fertility in some studies. Vegetable protein such as chickpeas, beans and lentils are great sources of protein. Other sources of course are animal proteins. Choose grass fed whenever possible to decrease saturated fat intake.

Protein powders can also be valuable. You can make them into shakes or sprinkle them on your low gi cereals in the morning. The popular whey protein powders are popular and effective for some people. Pay attention however to the back of the canister and if it says, "not suitable for pregnant or lactating (breastfeeding) women" then you know there are many artificial ingredients that could be hazardous to your health even if you aren't pregnant or breastfeeding.

And remember FAT does NOT make you FAT. Healthy fats from avocados and nuts are just a few examples of good fats you can increase in your diet. So the proper balance of proteins, slow burning carbs and essentials fats are so important for your overall and reproductive health.

Exercise is also very important and should be incorporated into your life 3-4 times per week to address weight loss. Cardiovascular exercise as well as resistance training is important to help you lose weight and optimise your fertility.

Speak to your practitioner about what type of eating plan is right for you as he/she may need to evaluate if you are having difficulty with your weight and your fertility because of a thyroid and or adrenal issue. Do not rely soley on blood tests to rule this out. Your symptoms are important to note as well.
