HI L.D RIght now I am also counting Cals. and Its all depends on how many cals you burn and you take in. I know that you need to have a 7000 cal def. (Cals burned-Cals taken in) to lose 2lb. a week.
I Know it might be some money but i ended up getting (gowear fit) and it tells you how many cals you burning in one day. Its and arm band that can be up loading into you PC and it will show you how many Cals you burn, how many steps you taken, also you can log in food you eaten, and it will show you how your Cal Deffiet is for that day. Its cool but its about $200 i payed, its works and its really motivates you do do what you planed. Check it out if you want hope it helps.
