Even though I haven't seen an Oprah episode in years... I popped on and read this thread.
I have been reading "The China Study" which is very interesting and talks about a whole foods plant based diet (basically vegan but without processed foods). Although I wasn't very happy about the beginning of the book calling the South Beach diet a high fat/high protein diet, I think the rest of the book is fascinating. One thing that struck me was that what we consider good cholesterol levels in the US and other western countries is actually considered high cholesterol in other countries that eat minimal meat/dairy. The other thing I found fascinating is that animal based protein may contribute to cancer cell growth. I had already known that animal based protein can have a negative impact on our calcium levels but I didn't know that it could contribute to something such as cancer.
I am personally trying to follow a vegan diet although I don't think I'd ever call myself a vegetarian or a vegan because I really have no real qualms about eating meat or dairy. In the past 2 weeks though, I've eaten meat once and cheese a couple of times. In the past week, I've eaten no meat and no main dairy items but I have eaten some things that contain trace amounts of dairy like my beloved bread
Is it hard? Honestly, no. It is a challenge sometimes, especially when eating out. I think it is fun to change up your diet and see how you can fit an eating pattern into your life. This is actually my 2nd or 3rd attempt at trying to follow a mostly vegan diet (sorry SoulBliss if I offend!) but the first few times I failed miserably. Even a vegetarian diet was only fleeting with me mostly because I find my weight stalling if I eat a vegetarian diet. It is my ideal though and has been for a couple years to cut out most, if not all, animal products. I work on improvement, not perfection

I think once you start enjoying non animal products, it is a lot easier to cut animal products out.
