let me first tell you how wonderful it is that you have chosen to become an organic vegan! Well done. Next let me give you a couple of hints when it coems to sticking to this new lifestyle. First educate yourself. When I first became a vegan (and believe me I couldn't find any references at all. I only met fat vegetarians
) Try and buy, or borrow some really god vegan cook books. I have a book called Vegetarian Cokking Without which I use quite regularly (make up large portions and freeze them, then just zap later for convenience). Try the library for some refernce books for a vegan lifestyle as you'd be surprised what animal products are actually hidden in packaged foods. Most beers, for example, is filtered with by products of animals.
Be aware of your nutritional needs also. Its so easy to lose loads of bodyfat if you're not careful. I was sporting a bodyfat of around 13-15% without any effort at all when I first chose to become vegan (thats just after I chose the lifestyle). I ended up anemiac (mind you I have always been a border line with my heamoglobin count anyway), and you can imagine everyone elses reaction regarding that! Loads of "see I told you its not healthy!"
I'm sure you'll really excel. Hope to see you on the circuit as a vegan competitor!
