Im age 15 16 in sept , 5Ƈ.5ft, & 166.5lb Im wondering how many calories would I need to take in to lose atleast 2lbs a wk. Also I would be exercising 1hr a day burning around 600 calories. It would really help if someone could tell me because I want/need to get healthy.

Try to aim for about 1200 calories of healthy nutritious meals, and stick with your exercise plan. You can do it.

following a diabetic diet is found to be one of the most effective ways to lose weight of course, along with cardiovascular exercise always 60% higher than your maximum heart rate (yes this means VERY INTENSE cardio), this has been shown thought studies so you are in a really good position!
cardio ca be a lot of things just to give you some tips:
Running
Bicycling
Swimming
Step Aerobics
Rowing
Rock Climbing
Walking
Handball

thumbs up for exercising
as for calories wise, dont pull out a calculator and counting, trust me, it gets discouraging and annoying
just eat healthy
like pick up an apple when you are hungry
drink water
no fast food
no fattie food
stay a healthy diet =)
then you will be losing about 2lbs a week
and mix up your cardio workout a little ya know
