How do you go from eating everything to being a vegetarian?

I don't eat too healthy...I do eat meat currently...I tend to eat junk food and many times I overeat...and I wanna lose some weight...so how do I go from eating everything to eating healthier? How do I transition from one to the other?How do you go from eating everything to being a vegetarian?
Gradually. Start by cutting some junk foods out, then when that gets easy, cut them out altogether.

Think up yourself a punishment. If you eat the food; you have to do something to pay the price.
