gonna start losing weight!! need advice!

So I keep putting off getting healthy and loosing weight and its time I start! I have some beach body dance videos I ordered months ago I never stared using, so ill do that for exercise and do my own at home, maybe go to the gym on the weekends. My worst part is diet! Im a vegatarian but that doesnt mean I eat so healthy, and I have hard time finding healthy foods I like or making meals. So what are some books I can look at or foods to buy that are healthy for a veggie??
