Speaking of steps, pick your cardio machine of choice (bike, treadmill, etc) and just spend time on it for now. Preferably you dial it just enough so that you arent huffing and puffing while doing it, while still being a workout and not just a stroll. That should be good for week 1 and 2.
Also huge disclaimer; NEVER and I do mean NEVER, consider calories burned during cardio when thinking about food. This line of thinking easily slips into

Remember the old adage, 'you cannot outrun a bad diet'. Cardio is still great for bodily functions, increasing your metabolism, etc, just dont expect to lose 20 pounds doing it in one week
