That's great for you! In the book it said the vegetable oils have a 1-2 year half life in our bodies. It will take 4-5 years before they are replaced with good fats. We are about 2 years in now. Our latest change is consuming a LOT of minerals. And by a lot I mean increasing dosage until you are running to the bathroom many times a day and then backing off a bit. The magnesium is insane once it's dialed in. I feel so much calmer.
