Cardio along with a little weight training to better tone. Watching my diet, I've cut hundreds of calories that I used to consume some days. I try not to eat fast food, and when I do I eat really moderately. I've lost about 11 pounds over 4 months, so not incredably quick but I still get to eat some foods I like, also I've gained a noticeable amount of muscle from the weight training so I can't complain.
