Hi Kay.
There's a forum for Ideal protein
https://www.3fatchicks.com/forum/ide...tein-diet-236/
It's pretty quite lately, but I think you will get some good input.
Here is the most active thread:

I did IP, just the packets, and also buying non IP packets that were less costly from NashuaNutirtion.com. Now that you know the macros, you could pick comparable products. Many of theirs were identical to IP, otherwise you pick the ones that fit IP.
I think you could get the same results eating real food. And maybe you'll enjoy it more. There are tons of wonderful low carb, IP-compliant recipes out there, and also here on 3FC, on the IP forum.
Huge Congratulations to you for 150 down!

And best wishes for your continued success!
