I found this article and found it really interesting! I'm transitioning into a plant-based lifestyle, which for me means mostly plants, with animal products sometimes. I didn't start out wanting to be plant-based, my body just was telling me that it can't handle meat all the time--my body just doesn't like it, and I end up feeling very heavy and tired if I eat it too much.
The benefit to this aversion of meat all the time (I still do have it a few times a week, but not enormous amounts each time) is that I'm filling in the spaces with plants, and reaping the health and monetary benefits from it.
Anyway, the article is from www.theage.com.au
