Body fat percent

ok my bfp atm is about 19... im not fat in my arms or legs or chest... just in my stomach and lower back. i have been doing cardio every day for the past 2 months or so. so they way to lower you bfp is just dieting and cardio right? are you able to over-cardio? i really wanna lose all my fat and get cut up... about to get on a diet and increase my running distance and speed. i found out that i burn 630 calories per running session and about 400 per lifting session so if i take in fewer calories than i burn the fat will melt away right? if anyone has any tips/advice/good diets lemme know.... :)
