Try cutting out dairy. A month and a half ago I did a vegan 30-day trial and had great results. I have no problem with meat cravings either, but it was socially difficult for me to keep the dairy out. So after 30 days I reintroduced a little dairy, and I just feel crappy all over again!
I agree with this....dairy is just nasty....liquid meat. Frankly, I'd rather eat a little meat from time to time than dairy.
Also...and this is just me, but there's a lot of data to back this up...I don't really believe eating a large amount of whole grains is good either. I try to always shoot for building my "pyramid" around greens, greens, greens, vegetables, fruit, beans, greens, and nuts. I have had by far the best weight loss and health results from this.
William Harris has a great article published a while age called "Less Grains, More Greens"
There's also a lot of "Vejunktarians" out there...who eliminate meat, but don't really eat much that is healthy.
My basic rule is I try to stick to unprocessed stuff that grows out of the ground.
