As someone who has suffered from fertility issues, I can assure you this is a very emotional subject and not one to discuss with people you don't know well (especially refrain from giving advice). If you can't help mentioning Paleo to them, I would suggest you don't mention infertility. Just talk to them about all the health benefits you've experienced and maybe send them to a couple of good Paleo/primal blogs that have a good post on infertility (but don't actually link the fertility page . . .).

Certain conversations are supposed to be awkward. Offering unsought fertility recommendations to couples you don't know well. Significant potential for mere awkwardness to rise to full blown offensiveness. If this is a selling point, full speed ahead.

Get your girlfriend pregnant and then wait until they ask you how you did it so fast.

touchy subject there, i dont know i would recommend anything, this is coming from an infertile paleo...

I have long term infertility and I have been eating paleo for 6 months. I think the changes in my eating will be generally helpful for my health but I may not still conceive because of them. There are multiple reasons why men and women have infertility, it is a highly personal and deeply painful area. I would not like unsolicited advice about improving my fertility from someone who may not understand what I have been through or the reasons for my and my husbands fertility issues.

I agree with the person who suggested talking about the overall health benefits of eating paleo. That is the way I would approach it. Let the other person bring up potential fertility benefits but don't do that yourself.

Fortunately or unfortunately, a paleo, low carb diet tends to restrict fertility in ladies because paleo just naturally is more satiating and thus folks eat less food.

This is because of our evolutionary genetic makeup and how our bodys react to the amount of calories consumed. Evolutionary wise, when we eat paleo, our bodys think we are heading into winter time when there is less food available or will be less food available to nuture a fetus to term. Lots of unwanted amenorrhea in the paleo community.

How to fix fertility in paleo females...females have to eat lots of meat and fat with some unprocessed carbs like sweet potatoes and yams and fruits in the late winter..early spring to in effect "fatten up the female body" to ovulate after coming out of what the body considered a winter famine..a dearth of food.

Just suggesting paleo as a fertility remedy may not be fruitful.

As to the appropriateness of your advise, how important is it to the couple to conceive? And how important is it to you to advise your GF to assist this couple? Why do you think you should assist this couple through your GF. If it is important to you, talk directly to the husband.

If you want third party validation, ask Robb Wolf He has talked about paleo and fertility. http://robbwolf.com/2009/12/29/the-paleolithic-solution-episode-8/

or a mild suggestion (when the subject comes up, or have the GF mention) that the chemicals in processed foods might be interfering with the hormones involved? best if you can find some links to related research- growth hormones in beef/chicken, etc.. but yes, wait for an opening- don't force the subject. HTH, and good luck to all, KM
