I went vegan for about 9 months just to try it and see how it went. I lost weight without counting calories or even trying and felt great. I also had plenty of energy. Most people actually get far more protein than you need to be healthy and normal so as long as you make sure to include some proteins in your vegan diet you will feel great.
The problem I found is that it is a pain in the ass. You can't really go anywhere to eat and there are almost no quick and easy foods you can make yourself. It was this reality,plus the fact that I sometimes found myself dreaming of meat and missed it that caused me to stop.
