I forgot to write that I saw last week in a bookstore a book "lowcarb for vegetarians" in Hebrew. Looked interesting.
I must admit that I am not that strict as you are. I did eat "kazait" matza with my mother-in-law's haroset. Of course, I blame only myself for not losing these last pounds. But I eat wisely and I exercise. I changed place a month ago and I go now to Ladies Fitness.
