Can a vegan diet help you to lose weight and even tone up? What are the best vegan foods to help you to lean out?

I am planning on becoming a vegetarian but I would like to know if anyone thinks that is good method to loose weight? What are the bad and good things about it? What are the types of food for vegetarians I know it’s no meat so what can we eat ?

Is it a healthy way to live? Also is it easy to stick with or do people usually go back to meat ? Thanks
