I am so confused!

My husband was diagnosed as a type 2 diabetic on Mon. of this week and was given actos and metformin to take daily. His blood sugar before meds was in the 400’s after 3 of meds his fasting blood sugar this AM was 212 (I know this is high but better than 400 right?)yesterday after dinner it was (2 hrs) 201. I don’t really like the dr. we have seen so far as he is not answering our questions. What do we need to do dietarily? Some websites say carbs are fine, some say no carbs what should he be eating???
