I find these Facebook groups pretty interesting and not overly time-consuming:
McDougall Friends, McDougall Maximum Weight Loss Support, and McDougall Mary's Mini…
They describe their diet parameters at the top of the page.
Then of course there's Jeff Novick, and Dr. McDougall, and Engine 2 diet. They post useful information. oh and vegsource. There were some very interesting articles posted there a few weeks ago about vitamin D.
