I already eat like that and have been for several weeks, and i'll tell you I haven't felt better! When I first began Atkin's I went ahead and bought the artificial sweetners, lots of bacon (still buy it but natural, and only once a month for a nice Sunday breakfast) lots of cheese (which could be aiding you in your inability to have normal bm's) and ate just like the book says.
However, I decided to change certain things like only buying grass fed organic meats, organic veggies, using more olive oil instead of butter, eggs high in Omega 3's (cage free as well -- oh boy, they taste so yummy!) and so on. I told myself that if I was going to eat such healthy foods, I could go ahead and cut out the artificial stuff, and any other processed things I was taking in.. I included the bars, and atkin's shakes in this catagory. So I did this, and feel absolutely wonderful. Before, I was ok, but now I really can tell the difference. It's hard to explain.. but I guess the point is... eat the good meats, fats, and veggies and there shouldn't be any complaints. I find it even funnier that your husband eats so terribly but has a large opinion on your way of eating. LOL Men sometimes.. <grins>
Rockgirl - I would love to hear how you feel after making your woe even more healthy. I know you'll see a difference.
