The best way is your diet and cardio. Work your entire body not just your fat pad.
Perform workouts.
Eat vegetables, whole grains, brown rice, oatmeal, high-fiber cereal, fruits, lean meats, eggs, fish and low-fat dairy, such as cottage cheese or Greek yogurt.
Avoid processed foods like deli meats, potato chips, frozen dinners and pre-seasoned rice and pasta.
Switch to soy, rice or almond milk instead of cow's milk
Eat often to increase your metabolism.
