I can only tell you that from my experience with doing lc and having hypothyroidism that I avoid all products with soy. I found that it was keeping me from loosing weight.

Someone told me the best way to do lc is to keep it real. So I try to avoid the lc snacks and most lc products because of that.

I also started reading lables very closely to see if they contain soy. If they do I put the product back on the shelve and look for something else.

Hope this helps, but only you will be able to determine if it is affecting you.

Good Luck with your weight loss.
