Hey bro, don't know what your training schedule is like, but 10-15 mins cardio warm up before resistance training, then 20-40 mins cardio after. Weight training imo, is by far better at burning calories throughout the day. You muscle mass is your metabolic furnace.
As far as loosing weight it's easier than you think. All boils down to calories in vs calories out. If you want to get serious, get a food scale and start measuring and counting grams/ calories. Once you do it for awhile you'll get used to it and figure out what amounts to what.
Try to swing to a higher protein diet, 1 gram protein per pound body weight. Low glycemic carbs, lots of green leafies. Cut out all processed shit. Like Arnold said "Stay lean and mean". And it's true, first part of a real diet you'll be grumpy and hungry as hell. Your body will be fighting you at every step. Btw, don't know your family situation, but if they're not on board with your lifestyle decision, you will fail, or results will lag. Dad might have to have boiled chicken instead of hamburgers.... oh, and forget about wing night, 1 lbs of wings are aprox 1000 calories....
Good luck, stay focused, keep your goals in sight.
