(Is this topic still alive?)
I've been vegan for over a year and I became vegan for moral reason only.
And even as a vegan I eat a lot of junk food.
However, I eat a lot of greens and fruits and grains. Specially all sort of vegetables, if I don't eat an all vegetables plate I feel tired and even angry. Being vegan made me start to cook more often (I already liked cooking, so it wasn't a big deal for me to start cooking for myself). I had to do a lot of research in order to avoid sickness and the first few months I had constant headaches because I didn't ate enough vitamins or nutrients or whatever.
When people tell me they want to become vegan or vegetarian I often tell them that they should make a lot of research and if it's on their possibilities, they could consider getting help from a nutritionist or doctor. Researching recipes is always encouraged.
Honestly, I love being vegan, I think I never had any meat cravings (sometimes, when I smell meat or chicken I think it smells good, but I don't actually crave it). My skin is less greasy, I have more energy, I haven't really lost any weight, but it wasn't one of my goals, so it's good. I know it may sound cheesy or cocky and that this is not an animal's rights thread, but I feel better knowing that I don't eat animals or contribute to their exploitation.
I was a huge food lover before being vegan and now, one year later, I enjoy my food as much.
