Good morning! I'll just stick my two cents worth in to add another example.
I've done a lot of tweaking on primal to experiment.
I replaced meat with dairy for four days.
I gained four pounds.
I dropped dairy and went back to meat.
I lost the four pounds in two days and kept losing.
I dropped all grains.
I have never had the need to binge since.
So, for me, for whatever reason, I like the results. I have lost 11.6 pounds since 1/16/12 and 9 inches. Those are the only changes I have made. Sugar, processed foods and vegetable oils, beans, nuts, etc. were only a negligible part of my previous vegetable, grain, and fruit diet.
I have lowered fruit intake as well, but it was never huge.
Hope this adds to your search.
