Many of the monetarily successful diet plans have additional "sales"
opportunities.  The zone has a line of products, so does Atkins and
Eades.
Ray (and Anchell) will probably be limited to book sales (or maybe
seminars),
unless he can start a pemmican factory. NeanderThin is a non-sellout
(interesting word) program that works on it's own.

By the way, I am not saying selling additional products is wrong.
