detox of environmental toxins for men and women before pregnancy and detox also to lose weight?

This is for all of those men and women who are considering having a baby or know someone who is.  I don’t know much about this but Dr. Bonnie Nedrow (a naturopathic physician specializing in environmental medicine) and Dr. Rod Newton (a chiropractor) talk about all the toxins that we have been exposed to and how many of them remain in our body and get locked into the fatty tissue.  I know some people won’t believe this, but what if it’s true and what if every man and woman did an environmental detox on their bodies and homes before trying to conceive a baby, especially with autism and other issues.  I wonder if that would decrease the numbers.  (They have a book called The Seasonal Cleanse Workbook:  Mind-Body Detoxification for the 21st Century.)

They also discussed a picture that showed two mice who had been exposed to the same food, had the same genetic makeup, etc., but one had been exposed to a minuscule amount of environmental toxin.  That tiny amount made the mouse significantly fatter than the other one.  So, they were saying if many toxins are stored in fatty tissue and people try to lose weight and that releases the toxins, the toxins need to be flushed out of the body somehow because if they aren’t then the body does what it can to protect itself and puts the toxins back into the fatty tissue and people gain back the weight.
