My best cycling was when I was completely ovo pesco vegetarian. So I too can't say much for meat being the full issue. But never hurts to try something when you don't have any better ideas.
I wish I could go back to the almost 2 years I didn't eat meat other than fish, but spouse and other family like their meat. But I have gotten them down to 6 oz or less per day since I'm the one doing the cooking.
