Health Advice Please

Ok, so I'm very unhealthy. I'm almost 17, 5' 11'', almost 300 lbs, but am very strong. I know I can still make a change for the better and that's why I'm here. I need help making good diet restrictions, exercise recommendations, and vitamin/mineral suggestions. I am always tired, and my lower back hurts. I don't eat too much junk food, and just stopped drinking soda. I work next to a specialty pharmacy that just opened and a farmers market. Anything will be helpful. Thanks
