Detox programs exactly like the one offered by Dr. Lauren Gouin is discussed in this month’s Elle magazine!

I’ve lectured on this topic in the past. I think detoxification programs are a great idea, but not for everyone. In the right setting they can support health body composition, improve energy and promote overall better health. I certainly recommend it 6-12 months prior to trying to conceive as a way of preparing the body and ridding it of excess toxins. 3 weeks of improving liver function and decreasing stress on the body can really hit the reset button!
