I do not even think the substitions are a good idea for me.

What I am trying to do is to re-orient my mind so that grain and sugar are no longer part of my lifestyle.

If I eat the sweet cake-like Atkins bar, or the bread-like MIM, I am just taking a step backwards by flirting with that which I can no longer have.

Sure... it may not be hurting my body... But I am making things more difficult on myself because I will not be allowing my mind to adjust at the same rate as my body.
