The Voracious Vegan and her 7 Days for World Hunger (if you missed it, lower down on the post she has links to each day). Super important information and a lot to think about. I didn't weigh my meals, but just ate one meal a day to keep my mind on her journey and that was tough. I've wanted to do something similar for years, but I always seemed to be pregnant or nursing (I am still nursing, but was sure it wouldn't negatively effect my milk supply). Parker was inspired by Tasha and would like to do something similar. I think we'll do a world hunger homeschooling project without him changing his eating habits.
Happy Herbivore is doing a 30 Whole Days Challenge. It may not be as easy as it sounds, even for those eating a "whole foods" diet already. Watch as HH and others go 30 days without processed foods.
