What is the best, fastest, easiest way to lose weight?

I’m a girl…All my life I have been overweight and I’ve decided that I’m tired of it. I want to lose weight but I don’t know what exercises are best. Please don’t answer with “consult/ask your doctor about this”. I want to know what is the easiest and fastest way to lose weight and how to keep it off. You could write a weekly exercise plan for me or just give me a few tips. Please Help!
