I want to lose weight and make my heart more healthy. what are some possible ways to do that?

That's terrific: The best way to lose weight is to eat a diet that is satisfying but lower in calories than what you're eating now. So unless you already know what to eat, find information about healthy foods and then make a plan to change your diet gradually so it lasts a lifetime.
