If i want to lose a minimum of 2 pounds per week how much should i exercise per day and how many calories should i consume i am 5'8 and weight about 180 pounds?

You will need to burn 3500 calories a week to lose 1 pound. So you would need to cut out 500 calories or burn 500 calories a day. You would need to double this in order to lose two pounds in a week. I just lost 40lbs myself, I am a bigger girl and weighed in at 267 at my heaviest. My resting metabolism was like 2600. So what I did was drop my calorie intake to 1200-1500 a day. I lost 40lbs in less than 6 months. Its a simple diet and it works. Don't tell anyone but I barely did any exercise :-)
